1st character(the lead guy.).probbably a knight or swordsman(a samurai dark knight or mercenary would be good but a DK and a merc have been done before.)hes called steve or something like that.hes a swordsman with a samurai sword.
2nd character(suppose the lead girl .).as in most FF games theres gonna be some kind of love story .she gonna be some girl that you pick up along the way(maybe someone your character know from the past.)and her job class i cant decide but id prefer it not to be a wimpy job class like white mage or somethin.
3rd character.cid.the(i bet youll never know what all write next!)the airship engineer(shock horror!!!).he attacks with a variety of spanners and screwdrivers and has some abilitys unique to his job class.
4th character and fifth characters.biggs and wedge.two guys you find a an army base.wedge has a machine gun and biggs throws grenades they have abilitys that they learn later which are unique and only they learn(no point in me saying that realy because every character does.
6th character.im making a few random characters now but im gonna make gungo the alchemist who has all the capabiltities of an alchemist and holds potion bottles which he throws at enimies.
7th.julie the red mage who eventually learns all of the BM and WM spells in the game and holds maces.(WM isnt always as good as alcheny but black magic pretty much the ultimate power.)
8th.???.a strange human like cyborg who joins you to find out his mysterious past and who he is.he is a monk which means he is a very powerful fighter he has a lot of hp but lack in speed he has some realy powerful abilitiy as well as having the mimic command.he has an ability called download which lets him learn blue magic of an enemy by using it on them.
hope this helps!
