Deep in Khornes realm of Chaos, underneath his throne of skulls is a small -extremely out of place- man door that has no business being there. And when Khorne starts to get uppity and even contemplates reaching for his big ass sword to take care of business, a lone metallic bang will come from that tiny door that will make Khorne sit the fuck down. That’s why he hasn’t gone and fucked shit up himself yet.
On the otherside of that door is a lone Doom Marine and his shotgun reminding Khorne that he will come in there.
Y’know, as much as I like this idea, Khorne would adore Doomguy. Especially the earlier incarnations. Pure weapon combat, no magic, straight up smashing the Argent energy shunts. I mean, please tell me that Bloodthirster of Unfettered Fury or of Insensate Rage doesn’t describe our boy.
Remember, Khorne’s also the god of martial prowess, honor, and individual strength. The one that patronizes those that carve the bloodiest swathes through his champions.
