This is Chad:
Chad likes wine, bright colors, and pretty boys. He’s a gay interior decorator and party planner. He has never killed anyone.
This is Oliver:
Oliver likes to smoke like a chimney, wear boring suits, wears glasses, ladies underwear, and is a serial killer who skins his female victims and makes lampshades out of their skin. He’s a doctor—like a real one. He also died before Chad was born.
This is Sylar:
Sylar is also a serial killer. He likes to wear black when he’s evil, and he’ll wear grey when he’s trying to be sort of good. He kills people because he likes to play in their blood and brains. He collects superpowers the way Chad collects Martha Stewart Living back issues and Oliver collects skins.
He only wears glasses in flashbacks when he’s still Gabriel Gray.
