Backstory: So, I'm not sure how I can realistically say a guy with inter dimensional travel literally on his fingers would just be here and stay for some reason.
So, here's my bs reason: He was brought here against his will and some god-like or unknown figure of tremendous power is restricting him here, or at least from permanently leaving here.
Equipment: Sling Ring, Cloak of levitation, Eye of agamotto (Assuming your cool with having the infinity stones)
