Most art they have for the games look nothing like the people in the game sometimes. Besides that picture of Garland was probally for the games battle sprite. They decided they needed more of a person for the FMV because a guy in grey armor with a bit of purple wouldn't be as cool I guess.

Besides it's Garland. End of discussion. Since when have you seen a fighter with purple armor, a horned helmet (needless to say, the same purple armor and horned helmet of Garland) and since when have you seen a fighter cast a spell on his sword?

1: RPGs don't show Bad guys Killing monsters!!
I disagree. FFV showed X-Death. FFIV had Golbez. FFVI the bad guys killed lot's throughout the entire game. FFX they kill all the time as well.

2: Garland's CRAP!!
Obviously you haven't (SPOILER)gotten to the end of the game, cause Garland IS the final boss. He transforms himself into Chaos at the end.
