Ok after reading some posts in the Barret thread i made its made me realise that a lot of stereotypes are presented - but then Broken in FFVII.
Ill go through the list of main characters :
Cloud - shown as being the Stereotypical hero - strong silent and confident in himself - when he's nothing of that.
Barret - see barret thread
Tifa - in all honesty Tifa is shown as being the loud outspoken slutty girl - yet she isnt at all - shes quiet conservative and very kind.
Aeris - shown as being perfectly innocent and weak - the damsal in distress - When she isnt considering that shes the one that saves the world
Red XII - hes a dog you expect him to be cute and fluffy - he isnt XD
Cait sith - Ditto for red XD
I cant think of any of the others at the moment - as Cid Yuffie and Vincent fall into there stereotypes perfectly. feel free to debate against my beliefs or form your own

I'd never really thought of it like that, but you raise some good points though. At first you do expect Nanaki to be a cute little dog (after you free him from the cage thing) but, well, he isn't xD
