You were the boyfriend of a hero, Jada. She was out fighting most of the time so you didn't really see her.

Then you disappeared.

Kidnapped by the villains, who wanted nothing else then destruction, put you under mind control, and made you more powerful than the heroes, even Jada. You could only fight it by dying, or when you'd had enough strength, but then it would come back.

After a recent rampage, you were put in a lair, waiting so the villains could finally take down the heroes. Of course, you look completely different from before. Then the heroes break through the roof, and land right in front of where you're sitting, weapons and things ready.
