I know he's in the Kingdom Hearts series but which game does he first show up in? I just started playing the first KH not to long ago, about 5 years late XD I just beat Atlantica, it was so confusing!! Anyway Awesome picture!! you make him look so hunky =w=
The first game to really feature him was Kingdom Hearts 2. But you can learn more about him by playing the Nintendo DS game, 358/2 Days. He is also alluded to in the secret ending of the original, and there is a scene in Chain of Memories where he is almost inadvertently mentioned.
