Jack Steeplechase (Earth-4605)

"We all wear masks, Jason. But the question is, which is the mask? The one that hides your face, or the one that is your face. The thing is, I took off my mask a long time ago. The mask I wore, it made me seem like a good and noble man. But bad things always happen to good people. I can vouch for that. I've seen a lot of good people die, and I've seen that in their final moments they take off their mask and they show you who they really are."
