Kinda looking for a manga where the main character changes like that, from pathetic to strong. Cat Street is the only example i can think of atm.

Naruto
Bleach
Parasyte

Glados is a bitch. She made me kill the companion cube, the only friend I'll ever have. 😢

Chibidoro-sama=Neko-freak

how does naruto have a weak and timid personality? same with ichigo, when i said main character i mean the MAIN character the whole manga revolves around.

oh, crap. I read it wrong. I thought you meant physically weak.
Love Hina
Gantz (doesn't really start out weak, but does get a lot stronger)

Kind of obvious ones for me are:

Othello (shoujo) comes to mind, don't know if you're interested in shoujo though.
