My big issue with the shiny Pokémon in overworld is that the lighting itself can really mess with the color of Pokémon and make it harder to tell at times, I almost missed a shiny mankey which is green because the lighting made both the shiny and regular dulled out like crazy

I love how your channel is basically “Pokemon For Adults”. Very insightful

I think the best solution would be to handle it like in LGPE. No sound to potentially alert you that you missed a shiny, but a visual sparkle effect to reinforce that the Pokemon you're looking at is really shiny. It really shouldn't be difficult to tell when you're staring directly at it

While I can understand the reasons brought up as to why both the sparkles and sound are gone as well as why this is the first 3D region with an abundant number of shinies that suffer from Garchomp syndrome, I still can't say I like the decision. I feel like between having to miss a few shinies I *was* aware of and constantly feeling like I'm missing something I'd take the former. I'm gonna miss a lot anyway, at least I know I struck out now.

Personally I find SV’s shiny hunting very anti disabilities. I suffer from a form of colour blindness which stops me from seeing certain types of colours, so I can’t distinguish between some regular Pokémon and shiny Pokémon. I also find it hard to see really minute details on Pokémon such as Frittle. I think PLA perfected shiny hunting for a lot of players who share the same disabilities as me. I would love if they either added back the shiny over world sparkle seen in PLA or even LGPE or a chime at least 😊

Honestly, it feels like SV are just major steps down from Arceus. I got Arceus AFTER I got SV since I originally skipped it but ended up getting it for Christmas. I used to breed shiny competitive Pokemon in older games and I love shiny hunting for funsies on my own so I was stoked to try it in SV but it was such a miserable experience that I actually started to make myself physically ill multiple times from riding in circles resetting picnics and focusing so intensely on the Pokemon glitching into the environment. I've also fully skipped trying to shiny hunt certain Pokemon like Tatsugiri due to the fact that each form has a different freakin' shiny and they're SO. SMALL. Getting Arceus for Christmas and playing it after dumping hours into SV made me regret those hours spent. It felt like they had all these great ideas and concepts for Arceus that were dropped for SV purely because they were so determined to make an open world game while not actually knowing how to make and program an open world game. I've been playing Pokmon since 1998 and grown up with + played every main line game, so I want to cut it slack but just like...they don't have a big enough team, they don't have the programming chops or knowledge, and they're rushing these games out too fast. The lack of indicators isn't demanding skill of the player, it's a lack of feature they didn't have the time/ability to program in due to other limitations they caused by lack of time/ability. Sorry this turned into a novel, I was genuinely looking forward to hearing your take and appreciated it. I just can't fully agree with it. I will however say you're freakin' right about Veronica Taylor forever being the voice of Ash to me haha

Something that's worth noting, which has probably been mentioned already but bears repeating, is that your Pokemon will NOT attack a shiny Pokemon in an auto battle via the Let's Go mechanic. This is particularly helpful for Ditto, Zorua, and Zoroark as they won't appear as a shiny of whatever Pokemon they're currently disguised as.

I think a significant downside to the way SV handles it though is how disproportionately not having a sound effect or animation punishes players who don't see color the same as everyone else. One of my best friends is color blind, (he has real trouble seeing the difference between standard and shiny Kyogre, as well as seeing some shades of green differently) and I don't think it's just a coincidence that he's the only one of our friend group who still has yet to find a shiny in these games. I wonder if you could approach a subject like accessibility in a future Tama Byte. So many games have upsides and downsides- like how LGPE may have been more accessible to people who had a tough time reading text on a small 3DS screen by nature of being on a home console and TV, but forced motion controls is a pretty big sticking point in communities where accessibility in gaming is discussed.

fun fact that i have tested multiple times in SV! shiny pokemon do Run Away and do not dissapear with weather! sillocobra and dunsparce dig a tunnel and run away when they notice you but ive found shinies of them and they cant! sudowoodo runs off and dissapears but once again the shiny can not! sandyghast melts in the rain, shiny does not. igglybuff, jigglypuff, hoppip, skipbloom all float away in the wind, shiny does not. bramblin blasts away in the wind, shiny does not. (i have a few clips on my switch showing this off when i found some that I could upload but getting them on my phone to upload is a Pain)

I find it odd that with shiny ditto in gen 2 you actually have some of the highest odds of shininess from breeding

I didn't realize Masuda Method was only published on his blog lol. That's crazy. You always drop at least 1 thing I didn't know in these. Also Gen 5 actually had 2 shiny boosted methods! There's a pass power in BW2 only that increases their odds! I know the weakest version of it makes the game XY normal odds, but idk the rest.

Suggestion for a Tama Byte? Maybe the Safari Zone? I understand why they removed the Game Corner, but we haven’t had a conventional Safari Zone since the Great Marsh in Sinnoh.

As many have mentioned, I do feel their logic, while it makes sense, doesn't work for those with color blindness; the accompanying sound effects in PLA worked so well because it allowed more people to notice the shiny Pokemon. I feel like there must be a happy medium.

Thank you for your contribution to our community, also thank you for making my childhood much better.

This is a very informative breakdown of how Shiny hunting works in Scarlet and Violet. While I don't actively Shiny hunt, I have friends who do, so I'll share this with them. I really like how you analyzed the changes in how Shiny hunting works between Legends: Arceus and Scarlet and Violet and theorized the justifications for those changes based on the changes to the games' mechanics.

I think the lack of a sound effect for shinies could have been just an oversight. It was a inplemetation for Legends Arceus that for whatever reason the didn't bother to bring it to Scarlet and Violet too since Game Freak was divided in different groups during development of both games and maybe not everyone knew they add this mechanic to Legends Arceus. It goes with the many bugs and glitches Scarlet and Violet have along with some odd things that used to work before but now not. For example you can order your Pokémon moves in your team but not in the boxes, something that never happend since Gen 3. Another one is you cannot nickname Pokémon in the boxes when in the Let's Go and Legends Arceus you could do that. I wonder if the studio have such messy enviroment, or is a consequence of crunch that increases the amount of mistakes in the newer games.

Yes, I think the reason they didn't have the sound/sparkle is because the combination of more complex map (easier for pkmn to spawn out of sight and/or reach) and how pkmn despawn creates huge potential for a frustrating experience, but probably also because, combined with the much higher number of spawns overall, shinies announcing themselves like in legends:Arceus basically becomes a common event that disrupts the gameplay. Even in Legends I sometimes felt like the sound interrupted everything else I was doing at any point it happened, in order to look around and play a game of spot the shiny... So personally I actually do not want them to do the sound/sparkle the way Legends:Arceus does it in SV or in future games. Instead, I can think of a number of other ways to "improve" the experience of finding shinies that I think would be nice: - display a shiny symbol next to the Pkmn name, in menus and in the wild (or/and different colored name) AND make Pkmn names more easy to see in general (the LZ button functionality in SV is just trash in its current state.. - I mean maybe add a toggle to display pkmn names on your screen when close enough in general) - add a sound effect to shinies BUT have it only play once you get relatively close to them (so it doesn't go off when the shiny isn't remotely relevant to what you're actually experiencing) - have new Pkmn games have an actual artstyle where Pkmn STAND OUT instead of blending in with an unexciting environment due to some dated striving for muh realism. The lack of outlines + weather/lighting as in SV is more often detrimental than it adds to the experience, but this gets quite subjective... + also, in regards to people with visual impairments, they should try to make the game itself more color-blindness friendly, whether inherently or as optional settings, because it's 2023.

Not having the sparkle and sound when they spawn is really frustrating especially when tons of shinies are barely different from the normal forms

"you'll be happy never knowing a shiny spawned at all" if the developers cared about that they wouldn't have put a shiny Pokemon scene indicator on you profile

gotta say, i really love the use of a webcam in these tama bytes. they make the videos feel so much more personal and down to earth which is the perfect vibe for these shorter, more laid-back videos. been loving this series!

I don't want to gatekeep others' shiny experience, but I'm definitely of the camp that what makes shinies exciting is their rarity, so the rarer they are, the more exciting they are to find. When I found a shiny Tangela in Crystal, it felt like my heart was going to leap out of my chest, it was such a special moment. When I find a shiny in Violet, my reaction is just "Oh, neat." I miss when it was 1 in 8000. Of course, I realize I'm probably just in the niche here, so I think a middle ground for this would simply to make the boosting odds all optional. Most of them are, but some, like gen 6 and up doubling the odds, or the gen 8 increase with each Pokemon defeated, are automatic and involuntary. It'd also be nice to be able to complete the dex without opting in to the charm either, at least it should have an option to be able to be turned off.

I’m surprised you didn’t mention things like marks or size differences, which I think were intended to add another way of making each Pokémon feel unique and individual. The knock-on effect is that even though shiny Pokémon are easier (read: more accessible) than ever, finding a shiny Pokémon with a special mark is very hard, and finding an especially large or small shiny Pokémon with a mark even more so. I think it’s a result that should appease players who feel like shinies have become “cheapened” in recent gens.

As much I hate this change I can’t deny the absolute thrill it gave me Alright so here’s the story, I thought I encountered a shiny swablu but sadly it was just a trick of the light so that sucked, later I once again thought I found shiny swablu NOPE it was a numel who phased into a swablu, at this point I’m just pissed until hours later I found an actual shiny swablu and it was honestly the most hype experience I’ve had with a Pokémon game in a long time

“Aw, this is a cute channel! I really hope she still uploads! :D” *8 Months Ago* “NOOOOOOOOOOOOOOO!!!!!!!! 😭😭😭”

A good method for singeling out shinies are the auto battles because your Pokémon leaves shinies alone. I never would've noticed some shinies without this. But all in all, I don't have as much fun shiny hunting as I had in PLA. Would be cool if you made a video about raids in SWSH and SV and how they managed to make them even more frustrating.

I heard a theory that there's no shiny sparkle and sound in these games, because there are so many pokémon spawning out of bounds, behind every wall basically, so you would have a shiny sound of a pokémon you literally couldn't get to pretty often, which would be even more frustrating than just racing by too quickly

i can understand people’s issues with it, especially ones relating to accessibility, but for me personally I think finding shinies in scarlet and violet is the most fun it’s been in the entire series 😭 it makes finding the unexpected ones feel so much more rewarding, too! i love these Tama Byte videos, and I’m also so happy to see more and more content from you! cant wait for more :’)

Love the video and keep up the great work tama

Holy shit, I didn't realise you were uploading again. This is great!

Honestly as someone who loves to shiny hunt I do not love shiny hunting in scarlet and violet. The lack of an indicator is annoying making me feel like I pass so many shinies. Also getting herba mystica is such a pain! I do full odds hunts for gen 3 which can take forever so In the more modern games I prefer easy shinies. So having to get herba mystica and play spot the difference makes shiny hunting in this game less fun for me.

It's also worth noting how so many potential shiny Pokémon are unable to be caught because they spawn in areas which can't be reached by the player, e.g. stuck inside walls. I'm sure lots of players would get frustrated quickly if they could hear/see a shiny right nearby but not be able to catch it. However, in my opinion the trade off isn't worth it when you consider how inaccessible shiny hunting in SV is for players with colour blindness, impaired vision, etc. I hope they go back to including the shiny sparkle and sound effect in the next Pokémon title. 🙏 Great video btw!! As someone who loves deep dives on Pokémon and game design, your Tama Bytes series has been super interesting and enjoyable!

I've been following Tamashii since my Childhood and I'm 25 years old now just got curious and opened my old yt account and visited her channel. Glad to see her again making videos. ❤ 7:46

Great Video!

I don’t think people don’t realize that Pokémon still spawn behind you as well as in front. If you walk forward while facing the camera, you’ll see that many Pokémon behind you will spawn for a split second before getting despawned again. I could see the amount of spawns you never see in game to be around 1/3 if not more.

Great video!

Wish they'd add more shiny variations, like instead of just Blue & Red Gyarados, they include Black and Gold too.

I can't believe I found your channel again, after all these years

This is good. Keep up the good work 👍

A shiny Tama Hero appears! Me: Gah! My eyes! *wildly throws pokeballs in random directions*

Somehow I knew this'll come up in your videos when I spotted my first Shiny (Mareep) the other day 😅 Considering how X/Y felt like the first time Values were acknowledged in-game (at least casually), it really does work as a good counterpoint to how Shinies were given their own showstopper with Red Gyarados 😄 Informative as always! 👍

That's a very good take I hadn't thought about. Players being upset if they were constantly being notified of a shiny just before they go out of range. It does require you to look harder, however with the performance the way it is, my eyes get strained quick. Also not sure if you're doubling as The Flash because you seemed to keep popping in from the right every few seconds lol

I never got into shiny hunting because it just didn't seem worth the time investment to me. Breeding a specific Pokémon that had just the Nature, Ability, and IV's you wanted was challenging enough!

One time in pokemon violet i saw a shiny rockruff pass by in the background during a trainer battle. After I was done with the battle, it had despawned. So making shiny pokemon less obvious in order to make passing them by less frustrating makes sense now :')

Love your content.

How I felt when I was shiny hunting Iron moth. Most of the violet paradox shint forms are very distinct and can be seen from a distance. Iron moth has the smallest changes and I needed to get real close to really tell. I can't even imagine shiny hunting Deering where the only change is the flower from yellow to white

Shiny Pokémon being almost indistinguishable just seems lazy to me this generation especially since the change where gamefreak chooses custom palettes. Also the developers doing everything they can to punish playing the game in ways they didn’t intend is pretty disgusting

agreed on the theory of no sparkles + sound bc of how the pokemon spawn, i still dislike no visual que (audio not as much bc im not sure how easy an open world game like this is to play for a blind person ?) bc of accessibility. i dont think a pop out effect like Legends would work but a small aura of sparkles around them like in Lets Go would be a good solution i have a feeling that herba mysticas will become easier to obtain in the eventual dlc. i dont use them bc of how tedious and head pounding farming them is but with the charm and 60ko outbreaks shinies are still super easy to get now that theyre shown on the overworld so im not complaining

I like this format of video. We used to get one 40 minute video a year so now I'm surprised to see a 8-10 minute video a week

I remember diamond and pearl, or at least platinum, did mention shiny pokemon (or different coloured pokemon) when you got the pokeradar, and talked to dawn/lucas outside rowans lab. tiny detail but.

Yesterday I lost a Shiny Great Tusk because of the issue you mentioned. It spawned at the last possible second while riding on Koraidon 🥺😭 I really wish they had kept the shiny sound!

Not really relevant but I still love watching your X and Y tutorials like how to shiny hunt or breed for IVs, thanks for these videos!

Why does the youtube algorithm hate this channel? In several years of watching poketubers, I've never seen this channel before.

Shiny Charcardet is a crime

do a video on power creep, edpecially with abilities. I would love to see your take on it

The shinies that are slightly different from the original are kinda lame. I just want cooler designs. I don’t know if anyones favorite shiny would be that new shiny Tauros for example.

As one who has been playing Pokémon almost my whole life, anytime I've found shinies in generations three through seven, it's been by accident. I don't have the patience to shiny hunt. I found a shiny Lechonk the day I started my Violet playthrough. Since I got the shiny charm, I have found a shiny Hawlucha, Venomoth, Hoppip, Skiddo, and Diglett. I'm not exactly a shiny collector, but I try not to think about how easy it is to potentially miss shines in SV, it is frustrating though.

It would be nice if that, in ScarVo, whenever a shiny does actually spawn in a cluster of pokemon or just in general, the game would make that specific Pokemon not be able to despawn unless you were to go into the main city, cross some invisible threshold separating the areas between each other, or exiting the game without saving, that way if people run past it and notice it at the last second, or if they even pass it, go to the Pokemon center, and pass by it again, they won't miss a shiny. I will say though, with the situation we have currently in the games, being careful and not constantly running is the way to go so you can't lose a full odds overworld shiny. But imo, if it's a shiny that's barely different from its base colors (like the Gengar line, Garchomp, the Snorlax line, Charcadet, the krikitune line, to name a few), you shouldn't feel bad about missing it, because it realistically isn't really worth it. It's barely different, it's ok. Maybe it's just me though 😅

9:12 moments before disaster, IYKYK

Excellent video!! Believe it or not, I'm actually breeding for Shinies right now in the original Crystal version. I'm using a Blue Ditto that I got from the Pokemon Blue trick(trading Red Gyarados to Blue version) Currently I've hatched 121 eggs trying to get a Shiny Charmander and still no luck 😅 I was hoping the Blue Ditto would up my chances but so far that is not the case. Haven't given up though. 🤞🏾

I still have my Battlestadium in my closet. So many great phrases said so slowly. "Lets. Have. A. Pokemon. Battle?" "Should we battle a. Fire. Pokemon. Trainer? A. Water. Pokemon. Trainer? A. Grass. Pokemon. Trainer?"

I agree, and I think another part of why they don’t play any sound in particular is just the sheer amount of Pokémon that’s spawn out of bounds, which they were certainly aware of. I can imagine people hearing a sound for Pokémon they were unable to get and going mad searching forever for it. It is cool, however, but they also made shiny Pokémon behave differently than normal Pokémon. For example, shiny voltorbs don’t explode, and Pokémon that can flee don’t when shiny. Shiny Pokémon also stay on screen for longer ranges and despawn less frequently

The lighting can be really annoying with certain pokemon. My first encounter in area 0 was a shiny corviknight, and I almost didn't encounter her bc I thought the light was just being weird. Two other corviknight that I thought were shiny weren't and actually were just being lit incorrectly

You would think that since PLA and SV both have their foundations in the same engine, something as small as the shiny indicator would carry over. Sometimes i really think PLA is better than SV because that game feels like it was crafted with a lot more love and respect for its source material whereas SV has clearly suffered from the corporate machine of Pokemon the brand forcing out the game to co-incide with the likely years of plans the higher ups have made for the entire proceeding generation of games. Even a year on (happy birthday PLA) i find myself going back to Legends: Arceus more than i do SV despite the newness factor which is strange because despite not really liking sword/shield that much, i have over 200 hours in those games. Idk what im really trying to say, but what I do know is these videos really make me stop and reflect and think.

Why do you have a polygonal snail at the beginning? MyLastBrainCell?

I've played Pokemon since Gen. 1, and up until Gen. 8, I'd found a whopping five random full-odds shinies. Between BDSP, PLA, and SV, I've found nine. Five are from SV alone, and I had two before I beat the first gym. It's almost more rare now to meet someone in a raid who isn't using a shiny. It's just a strange transition, that's all.

Hello Tama! I have been a fan for years now. I know this may come off as rude, but I don't intend it to be that way! Have you thought about getting a better camera for your videos?

I'm still hoping for you to do a video on satogoh

Loved the video. Personally I wouldn't go out of my way to shiny hunt, I am ok with randomly finding them during my playthroughs. It makes them more special for me. As for another video topic, i would love if you talked about the title of legendary pokemon, for example what are the basic "criteria" that make a pokemon legendary and how in the more recent games term "legendary" doesn't feel like that anymore, since there are pokemon that are almost as strong as legendaries without reason.

As someone who bred a shiny Mareep in gsc , i only did it because of the color regardless of the rarity (since the odds are 1/128) and i just really adore its shiny form (it looks like cotton candy ^_^)

I'm so happy I got a shiny Wooper on my first post-Shiny Charm outbreak, no sandwiches, and last night I got a shiny Scorbunny on my 13th egg! With a japanese Ditto of course

That lottery analogy is genius btw

I really want to know what camera you’re using, I’ve complimented you before on the aesthetic and I feel like I’m in a retro ghost in the shell / Janet Jackson scream video when I watch this

also in SV auto battling is a good way to see if a pokemon is shiny or not - your pokemon will refuse to fight a shiny, making it a good way to spot shinies that don't look too different from the normal ones

I'm a very casual Pokemon player. The only shiny I've encountered was an Eevee distributed in a Diamond/Pearl event. Never once encountered a shiny in the wild. Not that I've gone shiny hunting. And last game I (nearly) completed was Sun/Moon so idk.

I love shiny hunting in gen 4 and gen 6 I did a whole Badge Quest in HGSS

Playing Violet worrying I might be overlooking a shiny is a tad stressful. This is my first playthrough so I'm more focused on experiencing all the new stuff not really on combing the area with a fine toothed comb. It does kind of suck because I would love to have a legit shiny but I really don't want to spend hours/dayd on it. It doesn't feel satisfying, it feels like a chore. I tried in the past and I was intensely bored.

Shinies have been massively devalued because of all the hacking. Wish game freak would actually develop a somewhat competent algorithm to catch these hacked Pokémon when people try to battle or trade with them.

Counterpoint to the no-Shiny Indicator in S/V: When rushing around on Koraidon/Miraidon, you can flick the stick back in the direction you came from to immediately begin a sliding turn and shift your direction. It barely sends you flying and can easily be used as a break if you think you passed a Shiny and want to make a check. It would be a lot simpler if even just the noise popped up so you can begin sleuth mode

I actually stopped playing Arceus because I got 3 shinys in 2 days while still going through the normal story. I felt kinda bummed that they weren't that rare anymore even though I wasn't doing anything to increase their odds. It took me from gen 2 to Alpha Sapphire to get my first shiny so getting several really quickly just kinda made me a little annoyed with them

I'd enjoy a video on your experience with the anime and how it related to your fandom as a whole. I'm also a Veronica-Only lover of the show

Your videos always showcase your wonderful intelligence. I always click so instantly!

It's silly that there is no silly indication especially with how small some of the pokemon are. I am always worried I am running past shinies with so many pokemon barely visiable. I have two shinies, 1 is a Hariyama, which is massive, so hard to miss. The other is a sinistea, which I accidentally biked into as I was making a turn. Would have 100% just zoomed past it if not for pure coincidence.

S/v is the first game that I legit shiny hunted and once I figured out the sandwich method, I had a full party of shinys in less than a week and I ran out of Pokémon I wanted to shiny hunt. Haven’t actually played the game in a month or two at this point lol.

0:22 poor cat wanted to come in but found the door closed 🥺

I wish they would make a Shiny combo variant do no one could have the same shiny.

Wish they still had the sounds for accessibility reasons

I hope you come back. Ya didn't croak on us, did you?

There is no other RU-vid channel breaking down Pokémon in this fashion. Way to go Tama!

I find myself always using the let’s go feature on Pokémon I suspect to be shiny because it really is so hard to tell. That’s a good way to confirm but doesn’t address the issue of respawning due to proximity.

YURRR I’m a up and coming poketuber and was just wondering if you’d want to voice a few lines for this Pokémon abridged series I’m doing! It may be like 4 or 5 but it would be for Roxanne in Pokémon emerald. Thank you for taking the time to read this and I know you’re busy as a RU-vidr so if you want me to pay you I got you homie. Thanks once again🙏🏾

Can't believe this has been 11 months ago

I agree that not having the shiny sparkle might just be a consequence of technical issues. Though I think they could have worked around it with some programming tricks, like giving shiny Pokemon a higher despawn range or something like that. On the other hand, I think it's also possible that the shiny sparkle just didn't return from Legends because both games were developed in parallel. By the time Legends released, Scarlet and Violet were probably already in beta. It's very possible that they just didn't get the chance to utilize any learnings from Legends for Scarlet and Violet. Whatever the case, while I do personally want the shiny sparkle to return, not having it does make accidentally bumping into one a lot more thrilling.

For me, the most controversial change in shiny hunting was when they decided to make the shiny charm non functional for wild encounters in BDSP, despite the item description in game saying that it does. I hunted exactly one shiny Pokemon in BDSP before I stopped. I gave up on Darkrai and Shaymin because 1/4096 is awful in 2023.

Ok, so a friend of mine (who did not cite a source) said that the reason they removed the overworld sparkle + sound is that so many Pokemon spawn out of bounds (inside walls, below the map, etc) that during playtesting, players were getting frustrated that they would hear the sparkle and not be able to find the Pokemon, or find that it was stuck in a wall. So rather than fixing the spawning conditions, it was easier to just sweep the problem under the rug (or under the map lol) by removing the animation. Again, take it with a grain of salt, as I don't know where my friend got this info. But we're both game devs ourselves and it seems like a very realistic theory to us.

I wonder if she's going to make a video on pokemon design and maybe region design

Yeah, I probably missed like 18 shinies.

I was shiny hunting skowpoke for the 7 star raid cuz i like to be fancy like that and it was a nightmare unless you got lucky and found a shiny slowbro instead its almost impossible to tell the difference. I literally got lucky and bumped into it. And when its night time its even harder cus they already look different. I love that they made shiny hunting easy but still rare enough that you are unlikely to find one without trying. I believe there was a problem with people buying shiny pokemon online and by making them a little easier. They allow people who don't have the time to spend literally hours if not days of their life looking for a shiny and by doing this they could potentially eliminate or at less reduce illegal pokemon trading.

Imagine a shiny spawning in an area you can't reach because Koraidon/Miraidon didn't get their fill of power-boosting sammiches yet.

An anti-frustration feature in SV's Shiny hunting is that certain Shiny Pokémon will behave differently in the overworld. Voltorb won't explode, Sudowoodo will run more slowly, and Sandygast won't dissolve in the rain, for some examples. However, they're not guaranteed to show the same mercy in battle if they have a self-KO move.
