You could do the easily identifiable ones in Naruto
One punch, Bleach, Gintama take your pick
If you want a specific character perhaps Sakura in Naruto?
you could also go old school and do sailor moon, dragonball, utena, gundam, pokemon, evangelion, etc
i don't really think there's a way to represent all of manga/anime with just one character because of all the different plots/genres/styles etc, but if you're looking for most identifiable then i'd say go with what esc said
How about the first "modern manga" character
Tetsuwan Atomu, AKA Astro Boy
I need to represent manga and anime in one picture, so I need one character who can represent them all...I don't care what genre, possibly shoujo or shounen seeing as these are most common.
I'm looking for ANY character with big eyes, unusual hair color, and some kind of unusual clothing
