Well i'm looking for anime that's about a boy/man on a magic or fight school and he's kinda the underdog/ the one being bullied, But actually he's the strongest one in school ( hidden powers or just to damn lazy to do anything)
the beginning of legend of the legendary heroes, chrome shelled regios or something like Toaru Majutsu no Index. I watched all the animes i could find with this setting but i hope some of you know another one.
Like the guy said above,
History's mightiest disciple, Kenichi is an awesome anime that fits your target. It's funny too.
Ichiban Ushiro no Daimaou is also good too. The main character is ostracized cause he's predicted to be the next demon lord (kinda hard to explain). But he's crazy powerful, and pretty much owns. This anime is pretty funny too, but has a lot more fanservice.
Macademi WAsshoi! - Magical School + Random Parodies/Fights/etc.
Negima: Mou Hitotsu no Sekai (Magic World OVA's + Manga) - TV series may not have been good since they stopped literally at the point where the series becomes great. The tournament where Negi begins to actually do some kick ass fighting. The Mou Hitotsu OVA's are quite a bit further ahead of that though. He isn't exactly being bullied but it has somewhat similar vibe as being looked down in his situation, by Fate, the antagonist of the arc or so it seems.
Touma (MC) is the most powerful person, but is classed as the weakest. Some school settings, but less further on in the anime as he goes on various missions. Ok, so its more like schoolchildren are involved, but not much school setting. Hard to explain lol.
Mahouka Koukou no Rettousei
Revealed early on (to viewers) that he is strongest, but only slowly leaked to his school. Protective of his sister. Cannot be touched in battle, but is classed in the lower half of the school.
