>>40537491Because it takes way more effort to come up with bullshit than it is to refute it.
Just a few:
Wurmple is different because it's a single caterpillar with two evolutions.
"Mammal" is an extremely broad category which indicates that OP is grasping at straws, by that same logic Skitty is also a Rattata ripoff.
Pidgey is a 3 stages line while Taillow is a 2 stages line. If anything it'd be the counterpart to Spearow. Wingull is Water/Flying which is different.
Vileplume and Victreebel are both Grass/Poison while Ludicolo is Grass/Water while Shiftry is Grass/Dark.
Gardevoir doesn't require trading to evolve.
Venonat and Venomoth are both Bug/Poison while Surkist is Bug/Water and Masquerain is Bug/Flying.
Greloom is Grass/Fighting.
Nincada has an unique evolution method where you get two Pokemon when he evolves, and all three of them have a different typing from each other AND from Paras.
