Gamer had a transformation that he constantly went through. But he was so ashamed of it, he never told anyone, not even his girlfriend, Jasmine.
For the last 4 years, every other day at exactly 8:00 pm, he was forced to go through a horrible change, and he didn't change back until midnight. Every time it happened, first his shirt and jeans disappear. Then his skin and shoes turn black, his gloves and fur (besides his quills) turn dark blue, his pupils become dark blue, his irises turn black, sharp claws extend from the wrists and fingers of his gloves, spikes extend from the front and back of his shoes, his quills turn dark blue with black outlines, and he becomes surrounded by a black aura. He looked like almost like a combination of Dark Sonic and "regular" Sonic. This transformation was called "Dark Gamer".
When it was complete, his energy bombs become 10 times more powerful, his telekinesis also becomes 10 times more powerful, he can run 10 times faster, and he can teleport in 10 times more situations (so he could teleport while chained up in this form, for example). But the reason he was ashamed of it was because of the fact that, like Sonic when he's in his Dark Form and Nebula when she's in her Rage Mode, his rage took over and he became a force for destruction. But unlike those two, the rage was caused by the transformation, not the other way around.
To avoid hurting anyone, he teleported to the desert at 7:50 pm. Then he spent the next 6 minutes running as fast as he could to get as far away from civilization as possible. At 7:56 he spent the next 4 minutes running around the area that he was in to set up several targets that looked just like Eggman, Sally, Scourge, and Gregory. He did that because, as much as he didn't want to hurt anyone, he still had to release his rage or it would kill him. When the transformation happened, he was able to release his rage on the targets for the next 4 hours.
He hated it so much, he never wanted anyone to find out. But, like most big secrets, it wouldn't stay that way for long.
