@Judas-la-Carotte
Perhaps the ability to manipulate machines (magically of course)? I'm kind of getting that vibe since he used to be an engineer; ok this isn't a superpower per se but maybe he has higher persuasion skills than normal seeing that he's not in the right time period and yet nobody suspects a thing. Not sure why, but maybeee the ability to read others' emotions, even if they're hidden??? I know it kind of comes out of left field oof
I'm sorry if any of these aren't good, if you want I can redo any of these or add some more!
