This is an amazing drawing, that is obviously bahamut if the people below are thinking otherwise, it does look more FF8 style than anything. Now I am a big FF fan and I have actually played 8 multiple times. 1 his name is diablos, diablo is either an MMORPG or a really fucking fast car made by Lamboghini, and 2 how does either of those two look like diablos? He isn't a dragon or a fuckin person with a sword. If you are interested and you haven't done so already, look up GF diablos or Bahamut on google images, they are both really cool and you will see where I am coming from. I actually think if anything the guy with the sword is sephiroth for 4 reasons. 1 sephiroth is notoriously left handed. 2 he has a really long samurai sword called masamune. 3 he has really long white hair. Finally he wears a long black cloak similar too the one in this picture. if you don't know who sephiroth is look him up too.
its bahamuth, diablo from ff VIII is more thin and the wings are diferents too, thats one for shure is bahamuth, compare it with bahamuth from FF IX and you get your response, the only one things going out from here is the pose, that is not tipical for bahamuth. is like is saying hey whats with you dude you still like to fight me? you crazy dumb!!!... but the draw look really good i like the stile!! yo you have an art point.
