If there were ever to be a Square representative, it should be Black Mage. Aside from Chocobo, Moogle and Cid, it's been a staple of the Final Fantasy series, sort of, and at least a recognisable character. One that has appeared in many Final Fantasy games that appeared on Nintendo consoles and handhelds.
And Black Mage is easier to handle than Chocobo. I mean:
Blizard (B, shoots ice balls straight forward)
Aero (^B, surrounds the character in a projectile shield, and also grants a one second hover, after and during which no actions can be done)
Fire (>B, shoots a homing fire ball)
Gravity / Demi (vB, halves damage done to you during this move, while dealing twice the regular amount of damage that would have been inflicted)
Meteor (Final Smash, unleashes a rain of meteors)
