[quote]As a note, I tend to prefer more natural like characters or underdogs with problems. It's mainly so we avoid accidentally creating characters like Arceus, Aang or Goku where the insanity level starts pretty high.[/quote]

I also like those characters, but sadly those characters sometimes undergo a Naruto or Ichigo transformation, basically they get lucky or have hidden insane super powers that keep coming out to save them for their one thousand mistakes...

Then even after learning said mistakes after say one or two years they become so OP that even though they stupid they just down right Godmode all the bad guys into oblivion...

Not many people realise it but Lelouche from Code Geass was an underdog even though he was super smart and had a rather OP power with a large limitation of working on someone only once and a bunch of other limitations...
He was still OP I admit, but he had limits unlike Infinite Chakra Naruto or Infinite Reiatsu and there were other things about Ichigo that just went too far, to be honest his the main character but I hated him the most in the show go figure and sorry for chatting so much just had all that backed up in my head after reading what you said
