Alright. My favorite characters are Minh and Guy.

I like Guy because, well, he's definately the coolest character of the mains.
First of all, he doesn't fall into any sappy love triangles or relationship garbage.
He is Guy. he is the embodiment of the FF1-3 hero. He takes more hits from the enemies, he dishes out damage like a monster, and when the going gets tough, he can talk to even the animals to make his way through. There's no baloney with Guy, and he's keepin' it real in a world of Fantasy.
So I like him.

But, even more than Guy, my favorite character is Minh.

This guy is just awesome. He has, like level 7 LIFE. Do you know what that means? This guy has resurrected 700 dead guys, healed 800. He's cast protection spells and safety spells- I swear this dude must have been a one man back up to the entire military force.
He's assistant to the king and queen, the best of the best, and, by the time I'M through with him, he can swing a club like a champion too.

And anybody who can club you to death and then bring you back to life is a badass in my book.

But that ain't all. He has a chance to totally show up the kids who are saving the world, and ally with them, but he's so awesome that he's got other plans. He doesn't need the help of 3 bastard children. He thinks on his own. He decides, "Hell, I'm just going to go and get Ultima and end this clown and donkey show.

Ironically, it cost him his life. And nobody could revive him, this man who'se saved thousands of lives.
His life puts the entire history of heroes of mankind to shame. Especially since we all know what use the kids used Ultima (sucks)
