Boss Battle Fusion Collab 

I love the implication here that Robbie Rotten is the final boss battle of Lazy Town

1 day later, sans was announced for smash bros

Oh boy I love necromancer can't wait to hear it in a cool soundfo-

may i ask why "The Beatles: Yellow Submarine" is a boss battle

That smash 64 part was so high effort props to the team

Little did you know. Cuphead vs. Master Hand can happen.

I NEED a complete version of that mash-up of Kirby with Plants VS. ZOMBIES

I didn't notice until now but at 5:57 Sans just went off screen from the game footage before coming to us.

The fact actual effort was put into the art for a simple 3 second jebait is what makes me love the people who work on this channel

That boss fight against the yellow Submarine was hard as hell.

the power of this collab summoned Sans Undertale into SSBU

After several watched I only now realize it says "Mega the Man"

Unironically i want to hear this songs in full

Damn, this is ambitious as all hell. Amazing stuff as always on these fusion collabs!

Imagine not knowing siiva and randomly finding this video with a weird title and an interesting thumbnail And then it's just megalovania so you quit after 10 seconds

Sans with the word "devil" written on his forehead is the most undertale way to represent the cuphead final boss, and I love it.

I was confused and then shocked and now very impressed with this idea.

Uncle Grandpa: “Don’t worry bro, none of this is canon.”

This was SUCH an amazing and unique fusion collab. You outdid yourselves yet again, SiIva team.

I need a full version of that King Dedede/Plants Vs Zombies bit at 1:58 I genuinely love that part.

Siivagunner: naah Sans will never be in King For Another Day Sakurai: toby fox kicked my ass in Smash so I added Sans

Hey guys it's me Ness earthbound just wanna congratulate my bro sans Undertale on this bop

Never in my life did I think I'd get to see the final boss theme of Plants vs. Zombies remade with the soundfont of "Hey Bulldog" from the Yellow Submarine animated Beatles movie. This is a theatrical masterpiece

Using DeDeDe’s weakness as “hypno shroom” was a nice touch

I would have never expected a friggin Yellow Submarine remix of PvZ. That. Now that is beautiful.

No one's talking about how the quiet bit at the end where it scrolls through the titles (6:28) plays a little bit from each melody as it passes its respective game, and to me that's the most magical part of this rip.

I want the full version of Smash 64 Chaos King. And even if I don't get it... *I'll make it myself*

Song list: MEGALOVANIA - UNDERTALE Evil Destroyer - Thunder Force IV Boss - Hyper Princess Pitch We Are Number One - LazyTown Porky Means Business - EarthBound Taisen 4 - Puyo Puyo Fever King Dedede's Theme - Kirby: Squeak Squad Brainiac Maniac - Plants Vs. Zombies Hey Bulldog - The Beatles Momentum Mori - Crypt of the NecroDancer Wood Man Stage - Mega Man 2 Final Boss - Sonic the Hedgehog 3 Fly Octo Fly - Splatoon 2: Octo Expansion Hooktail Battle - Paper Mario: The Thousand-Year Door Chaos King - deltarune Final Destination - Super Smash Bros. One Hell of a Time - Cuphead For anyone who was wondering.

What I'd give to get a full version of Dedede's theme in the Plants vs Zombies soundfont

I actually love this, have a theme from a game, then remix that theme in other style, then that in other style Fuck, I need more of this

The joke is that I don't know half of these games, but this is still fantastic

Everyone in the comment section is like "can we have the full version of this one", but deep down of all of us, we all know it will never happen

I can’t believe sans *actually* got into smash

That art of Ness in the Puyo Puyo style was actually pretty fresh tho.

You feel as if you're going to have a High Quality time.

That "Crypt of the Necrodancer"-style cover of "Hey Bulldog" was amazing.

God BLESS that Yellow Submarine x PvZ collab. If there were ever a full version of that I’d probably die happy.

Goddamn it. I dunno what I was expecting, but it definitely wasn’t this.

Therapist: “Earthbound Robbie Rotten isn’t real, he can’t hurt you.” Earthbound Robbie Rotten: ゴゴゴゴ

>PVZ in rip Instant addition to my playlist

This is basically Inception, but with music.

amazing to see how 5:26 accidentally predicted the direct

The PvZ+Yellow Submarine crossover honestly slaps.

This is probably the sickest fusion collab yet, good job everyone

I was actually expecting just plain old Megalovania to play uninterrupted

I actually didn't get the gist of the collab until like, the 4th or 5th section. That's actually a unique idea, taking a list and playing Chain Reaction with it. Color me impressed, SiIva team.

5:12 Ah yes. My favorite ssb character. *LOG*

This is not a simple fusion collab. This is the future of the fusion collab: THE COLLAB CHAIN

I like that I can still appreciate this video when I only recognize less than half the music

This may be the most creative video on the channel. Also, please for the love of god, do more PVZ stuff. Edit: I still listen to this from time to time. Decided to check out some of the original songs, and I must say, the Hyper Princess Pitch boss theme and Taisen 4 (Puyo Pop Fever) are some personal favorite, both in and out of the colab. Speaking of, we need some more Taisen 4 please.

I love that you can hear Goombella talking at 4:16 and it just naturally feels like part of the song. Like it's needed to complete the Paper Mario aesthetic

I love how sans' devil costume is just the word "devil" written on his head

Glad to help in the Collab! I provided the Deltarune King model/animation used in the N64 part of the video!

0:00 - 0:31 MEGALOVANIA in the style of Thunder Force IV 0:32 - 0:47 Evil Destroyer in the style of Hyper Princess Pitch 0:48 - 1:01 Boss in the style of Lazy Town 1:02 - 1:15 We Are Number One in the style of Earthbound 1:16 - 1:36 Pokey Means Business! in the style of Puyo Pop Fever 1:37 - 1:57 Taisen 4 in the style of Kirby Squeak Squad 1:58 - 2:18 King Dedede's Theme in the style of Plants vs Zombies 2:19 - 2:40 Braniac Maniac in the style of Yellow Submarine 2:41 - 3:13 Hey Bulldog in the style of Crypt of the Necrodancer 3:14 - 3:27 Momentum Mori in the style of Mega Man 2 3:28 - 3:48 Woodman's Stage in the style of Sonic 3 & Knuckles 3:49 - 4:01 Final Boss in the style of Splatoon 2: Octo Expansion 4:02 - 4:29 Fly Octo Fly in the style of Paper Mario: The Thousand Year Door 4:30 - 4:56 Hooktail Battle in the style of DELTARUNE 4:57 - 5:25 Chaos King in the style of Super Smash Brothers 5:26 - 5:53 Final Destination in the style of Cuphead 5:54 - 6:08 One Hell Of A Time in the style of UNDERTALE

0:15 this should have been the whole song this slaps

3:30 *Mega The Man* My favorite game.

What a wild ride this one was. Definitely a step up in production value. Well done to everyone involved in the making of this fantastic rip.

I guess this is what they thought we deserved after the “Farts and Hearts” incident.

That zomboss squeak squad mashup is godly, two of my favorite final boss themes, mixed into one divine concoction

I can't believe a Paper Mario TTYD Repainted joke got into this collab. I shouldn't be surprised but I am.

Having sans represent all of the boss themes really puts an original twist on it instead of him just being “the Undertale guy”

I like how Master Hand has four fingers just to fit the style of Cuphead.

Paper Mario x DeltaRune... The crossover we need

This fusion collab manages to combine the chaotic-meme-orgy fusion collabs and the constant-changing-soundfont type fusions collabs really well. Super cool idea, well done SiIva team!

2:08 "Weakness: Hypno-Shroom" Yeah, pretty much.

Really admired the reference to the previous fusion collabs shown in the Smash Bros character select screen. For a second I just thought they were doing a funny with Steven but then it clicked when seeing everyone else.

3:49 YOO! THAT SO GOOD!! Never have I ever thought to myself, I wanna hear "Off The Hook" sing the freakin' Big Arms theme!! Incredible work!!!

...alright, I'll just about forgive the D-Va and Kingdom Hearts incidents after this. *Just about.*

5:53 I NEED THE FULL VERSION OF THE "ONE HELL OF A BAD TIME"

I see now. The rips prior were our final boss fight. A fight of faith.

coming back to this after the shop collab and holy moly, how far this channel and the sublime creatives behind it have come....

Kirby should be: "Poyo Poyo Fever"

6:00 *sans was too lazy to dress up so he wrote “devil” on his skull with red sharpie marker.

THE SANS FAKE OUT LMAO Also wow, this might just be the best fusion collab to date. Excellent work, everyone involved.

1:37 this part was amazing and I freaking loved squeak squad (or mouse attack because I live in the uk and we always get the garbage names) so I want a full version of this and 1:58 because I am an insane Pvz fan

5:13 Hey, those are the previous fusion collabs!

I need a full version of the "we are number one" in Earthbound soundfont

When are we getting a full version of the Deltarune X Smash Bros. and the Plants vs. Zombies x Kirby segments

1:15-1:36 Y E S I unironically want this as a full song.

Interesting reveal today from the SilvaGunner channel. I'm not a master at editing, but these collabs look like they're a ton of fun to participate in.

So many bops, damn! Was not expecting Paper Mario TTYD, Cup Head, THE BEATLES!?, all the artwork looking so stunning. The e n d i n g. 5/7

A brawl is surely brewing now holy shit

1:02 JESUS CHRIST! ROBBIE LOOKS LIKE HE’S GONNA TEAR YOU TO PIECES!

*_get dunked on, yall thought there would be a kfad2 reveal_*

Can we have individual rips for each of these?

2:19 Let's jus admire this part for a sec, because I want a full version of this.

The amount of dedication and attention to detail in these fusion collabs are always an awesome experience

Crazy Dave: awab od au KDDD?! (How can i help you King DDD?) DDD: I need a Flower to cloba dat der Zombie!

We need a full 'One Hell of a time' in megolvania's sound font pronto.

Ah yes, the real final boss of mega man 2, woodman

I like how most of the villians have some evil stance, but because king dedede's a hero he's just smiling and waving.

it's like witnessing a snowball roll down a mountain if the mountain was made of musical notes and the snowball was made out of memes

4:54 Fandom: **sweats profusely**

1:57 i wish this had a full version. Whoever made it is awesome

1:22 "PK fire. PK flash! PK thunder! Okay. Okay. Okay. Okay. Okay. Okay. PK STARSTORM!

I NEED THE FULL VERSION OF THAT KIRBY SQUEAK SQUAD AND PVZ MASHUP I NEED IT NOW

It took me like 6 songs to realize the pattern of this Fusion Collab. I love it!!

Love the yellow submarine inclusion.

0:48 man I want to hear the full song of this

Subtitles: Music Deaf People: Damn this is fire
