Who is this guy?

Wrath of the Cosmos expansion, environment deck the Enclave of the Endlings, card Hall of the Terminarch. Who’s that Dolemite-looking dude next to Legacy?

Black Fist

Mr. Fixer, before he became a mechanic.

I really hope that’s a joke.

Okay, I’ll bite, it sounds like there’s a story there. How’d pre-Mr.-Fixer Mr. Fixer end up in Kirbyton?

His first appearance was as Black Fist. It’s not confirmed but I can’t see the groovy character in the Hall of The Terminarch being anyone but H.R. Walker.

Especially with that robe matching what fixer wears on his character card, minus the ripped sleeves.

Here's where Christopher posted the high-res image, if anyone needs it.
