Just a silly thing I decided to make one day a couple years ago. Everyone needs a stereotypical evil twin/evil side. This is Big-Red's dark half, Dark-Red.

Red becomes this black hole of a creature when he drains the last of his energy. This form is not Red in mind. It has no moral, no mercy, no guilt. It only seeks to absorb energy to return to the Big-Red state again. It acts on instinct, because it is more of a self-defense mechanism to protect Big-Red when he's run out of energy. That's not to say it's stupid; it's incredibly cunning and vicious. It's abilities are mostly unknown, but what has been seen seems to resemble the characteristics of what could be called a "black hole organism". It can absorb amazing amounts of energy quickly, including surrounding light to turn an area completely pitch black, it has some control over local gravity, and it can reverse absorbed energy into attacks.

TL;DR: It's a form Big-Red turns into to protect himself when he's run out of energy blah blah blah evil side.
