Earth-X (or Earth-9997 if you don't want to mistake it for the DC Earth where WWII never ended) is a parallel world in the near future where Black Bolt released the Terrigen Mists into the atmosphere, turning everyone into a superhuman. As you can imagine, that pretty much fracks society up and the result becomes an extended What If. But I'm less interested in the What Ifs here than I am about the What Abouts. Specifically: What about Rom in this alternate Marvel universe?
He's there! In Universe X #3, Captain America, Baby Mar-Vell and a super-powered Ka-Zar jump to Belasco's version of Hell/Limbo and find they're all the same. So of course, you've got Dire Wraiths there. If any of this doesn't seem to make sense, please note that Hell has indeed frozen over.Ka-Zar's mutate ability, by the way:
Steps into the fray: Rom! Proving that you never give up the fight, and that the action figure may be copywritten, but not his damn accessories!
And I like that his shield is a piece of his armor, too. It's not a big role, and we don't get much in a way of explanation, but you can imagine Rom dying and spending the whole of the afterlife fighting Wraiths. In the end, he gives his Neutralizer to Cap, giving him the means to destroy his enemies without killing.
You know, that reminds me of Cap yielding Thor's hammer. I bet the guy can pull Excalibur out of a stone too. That's just cool.
