But then the question comes up, who would they donate?
When you think Square, who do you think of? Cloud comes to mind, but he hasn't appeared on a Nintendo console.
(Actually, he has. The Kingdom Hearts GBA game.)
Next in line would be Sora. He's recognizable, has an established fan base, and has made an appearance on a Nintendo console. Though, he ranked low in the polls, and would Square go through the trouble to convince Disney as well?
Next would be a character from the NES or SNES Final Fantasy games. But those characters have smaller, and more scattered fan base.
The most logical character from that stand-point would be Geno, in my opinion.
He has a large fan base, ranked high on the polls, and they have no use of him as of now. Geno would be an easy, quick, and cheap way to be represented in Smash Bros.
