Whenever Robert Jekyll is angry, injured, or sometimes aroused he transforms into Hyde, an anti-hero with the superhuman powers of great strength, speed, and invulnerability. Unlike Jekyll, he is confident, risk-taking and lives on the edge. Hyde seems to be a less dramatic transformation than that of Robert's grandfather Henry Jekyll's alter-ego, Edward Hyde, in that not only does he continue to refer to himself as "Dr. Robert Jekyll," but for the most part he is physically identical to his counterpart (unlike Mr. Hyde's more grotesque appearance).

- "Oh, no no, the question is, what am I?"
- "Thanks for waking me up, Cyclops. I wouldn't miss this for the world."
- "Well, that's enough speeches. I'm gonna go break something."
