He likes to be in a suit. He's also always caring his gun around. He doesn't like demons. He even mocks them. He also considers Sonic.exe one, and said to kill him like a pest. During the battle with Sonic.exe, he needed help with AGK. They both traveled on Gravity Blocks above the city. He just kept on shooting Sonic.exe, and a success it was. It was so much, Sonic.exe used a portal as a shield. Only to be stopped by AGK. To finish him off, he shot a cloud that shocked Sonic.exe to death.
Fortress of Doom
This is a location in space. It's where he lives. AGK used a Gravity Block to get to him.
