I'm not gonna delve too deep because if I do I'll go into hyper-critical OCD mode over stuff.

I actually have a RWBY character designed after Nikola Tesla who takes a few design cues from Tony.

Mostly in the personality area, though he also iterates improved versions of his weapon in Mk versions like Tony does the Iron Man suits.

His weapon btw started off as a pair of gauntlets that shoot lightning, he has a ton of different versions that he keeps in a sort of armory/vault in his house. He isn't actually a Huntsman (flunked out of combat school) but he keeps building new versions of his old weapon as a hobby.
