BEST Starter in Every Pokemon Region! 

Don't forget that in the original Gen 1 games, bulbasaur destroys Erika and her gym because they will just spam poison powder, which will do nothing to bulbasuar or whatever form it's at at that point

well explained and good

Venusaur - Yes Feraligatr - Nope, its actually Typhlosion. Feraligatr and Typhlosion are tied in neutrality and type weakness, but Typhlosion has 2 advantages, which Feraligatr doesn't have. Taking movesets into consideration isn't really fair, considering Totodile cannot even learn Ice Fang until level level 20 (And that is only in the remakes, its not even able to learn any Ice moves by level up in the originals, its like saying Charmander is the best to use in Kanto due to it being able to learn Fly in Yellow and Metal Claw in the remakes). Swampert - Yes Infernape - Nope and its not even close. Best starter in Sinnoh is Torterra. Torterra is strong against Rock, Water Steel, Electric (With the immunity even), Fire and Ground, while its weak against Ice and Bug. Infernape is strong against Grass, Ice, Steel, Rock and Bug. However, it has more weaknesses than Torterra, since its weak to Water, Ground and Psychic. (So it has more weaknesses). However, also looking at Cythia's team type wise, Torterra checks Lucario, Gastrodon, Milotic + is the only Sinnoh starter not weak against Garchomp. Emboar - yes Greninja - Nope and its not even close. Delphox does way better in a playthrough. Greninja is weak against Fighting, Electric, Grass, Fairy. Delphox is only weak against Rock during the gym run, while it has only 2 weaknesses overall with Rock and Water. Delphox is strong against Bug, Fighting, Grass, Ice and Steel. Greninja is only strong against Rock, Psychic and Fire. Primarina - yes Cinderace - Nope - we have 2 different versions with 2 exclusive gym leaders, however, overall Inteleon is the better mon, since due to the lack of Electric type specialist, its only weakness is Grass, while itself is strong against Fire and Rock (In Sword). Cinderace is weak to Water and Rock (In Sword). In Shield, Cinderace loses its Rock weakness and gains another advantage with Ice (Next to Grass). Leon is gonna be the deciding factor here, which makes Inteleon fare better Skeledirge - Nope. Skeledirge reigns supreme during the Gym Run (Being strong against 6 out of 8 GL and neutral against Larry - while also being weak against only 2. Ququaval reigns supreme against the titans (Its only weak against Bombirdier) and has the advantage over the rest, while neutral against Dondozo/Tatsugiri. Quaquval also does best against team Star, being strong against Fire and Dark, Skeledirge doesn't have any advantages type wise (While being Weak to Dark) and Meowscarada is weak against 4 out of 5 star members. I haven't even talked about the Elite 4 yet, where Skeledirge is only strong against 1 member (Steel), with Quaquaval being strong against 2 (Steel and Ground). If i take into account Blueberry Elite 4, Ququaval is strong against 2 of them (Steel and Fire) while Skeledirge is only strong against 1 of them (Steel). However, i am not going to take into account Blueberry (Not that it effects the end result anyways). Quaqual is the best to use in the game, as its the best to use in 2 of the 3 paths (Titan and Team Star). In the long run, stats, abilities and movesets don't matter if you cannot do something with it (Like, if we line up movesets, by proxy in every game the Water types are the best, because they tend to have the best movesets as well). Taking Protean for Greninja is problematic in the grand scheme of things, since Greninja didn't have acces to Protean in normal playthrough, since the abilities weren't released, nor could you breed a Froakie with Protean.
