Stephen Thompkins (Earth-78)

"Bravo, Mr. Nashton, able to sustain such a traumatic experience, and still overcome it. It's a remarkable feat. I salute you, because you've not only endured, but prevailed. I believe I speak for all of us fellow colleagues and victims how delighted we are for you to make this group and help us coup with the collateral damages."

Doctor Stephen Thompkins is a surgeon at the Elliot Memorial Hospital, husband of Lisa Thompkins and father Mackenzie Foy. Formerly a abusive and manipulative family man, Thompkins was captured by the Joker and forced to undergo his twisted challenges and mental games alongside Ben Urich, another victim of the serial killer. After having to cut his own foot to survive, Stephen was saved by Joker himself, who manipulated him into becoming a part of his group, which he accepted after he learned what his acts have caused.

Becoming his secret follower, Thompkins helped the Joker into numerous of his perverse traps, such as the key behind Michael Lane's eyes, and blinding Matt Dent. Stephen eventually joined Edward Nashton's Joker Survivor Support Group, secretly observing his lies. As a last request by the Joker, Stephen was tasked by him to watch over Hannah Quinzel, before she was killed by Frank Simpson. With the help of Mike Ward and Chris Flass, two survivors of of the Joker, they took Simpson and locked him up in the Bathroom, the place where he was first locked in, but giving him no chance of survival
