I mean, they both… have blue eyes. It’s so obvious now, isn’t it? And stop, because I know what you’re going to ask me next.

“Tarryn,” you’re going to ask me. “Is Commander Keen – whose real name is Billy Blaze, everybody totally knows that – also perhaps related to Wolfenstein’s Nazi-punching Übermensch William Blazkowicz? Because those names are kind of similar.”

Yes, he is! That’s Commander Keen’s grandpappy. The id Software catalogue is a family business like that.

Responding to a fan’s question on Twitter about the DNA relationship between the three, id co-found Tom Hall confirms that they’ve probably even spent Christmas holidays together. Not in as many words, as such, but it’s definitely implied. Can you imagine Doomguy in his cyberdemon onesie, opening up some socks? I can. Now.

With his model physique and that “saved the world from the Fourth Reich, no big deal lol” thing on his Tinder profile, BJ was always going to be popular with the ladies – but the dorky Billy Blaze, not so much. I won’t make any jokes about Commander Keen’s “pogo-stick”, though, because he’s only 8 and that’s gross.
