I wanna know in Shounen animes.

I wanna know if there is an animé villain ou bad-guy out there in the animé universe that is able to beat nakama power. Seriously I'm just getting irritated about those power-ups. Some baddies are just too powerful to beat and the protagonist wins because of this. It's like toi can pass a written exam just par believing in your Friends and having the will to protect them ou something.

The only thing I can think of are the titans in Shingeki no Kyojin and I liked those titans because of that reason.

I will be truly grateful to anyone who réponses and I'm probably gonna insta-fave the animé character mentioned. Thnx!
