Open with Zack, nostalgia trip as he started the whole thing
cid sounds good,
third definitely holds a STAFF. it's a fire wiz. should be aerith
next one holds an axe, could be tifa
after that another sword knight, could be cloud ( maybe with a slightly edited suit as a 'young cloud' )
another axe, could be
a small staff, this could be vincent with his claw
another spear, could be substituted with yuffie and her shuriken
this one has some weird kind of weapon that resembles a staff as well. Could be aerith again
this one has a spear again
second to last one has a big axe
last one has yet another sword, should be cloud
big one should be septh
if you can get models to just use the knights weapons, then you wont have any trouble. I dunno if you can though
