Lloyd is much akin to Cless, Colette is much akin to Mint, both characters from ToP, which is a fair point to base characters on since it was an earlier game in the series.
I'm sure there's some kind of basis for all of the characters from other Tales games too.
But EVERY DAMN HERO is either obsessed with justice and protecting people, or at first doesn't care and the ends up being obsessed with justice and protecting people.
You'd be hard pushed to find a different hero-archtype.
