Honestly Incineroar isnt even that bad. I think people are still salty that the fire starter turned into a standing bipedal yet again, hence the hate.
No, Incineroar is that bad. I'm not one to get salty over fire starters because I always expect the worst from them. Incineroar isn't just your average underwhelming fire starter, it really is a fucking embarassment to the Pokémon franchise. It's not just a hideous looking design, it's all wrong. His proportions are all garbage, his fingers look like some boneless jelly, the whole thing is just terrible taste from top to bottom.
That isn't to say the other ones you posted are much better, but I wouldn't say any of them is as bad.
