Well, the guy picking up the hammer at the end of Fantastic Four had a medical bag with D.B. on it. Not that that means anything. Could’ve been former Detroit Red Wing Doug Brown for all we know.
Skrulls sound possible, but my money is on this being mind control. Thor’s back, and I can’t wait to see how they work that out. DeciMation reboot maybe? Anyways, it stands to reason that if Thor is back, Loki could be back as well.
I was wondering about the “why” regarding this character as well. What would drive a god to adhere to the jurisdiction of one of the subdivisions of planet earth. I’m sure that he’s sees “hero’s” as earthly extensions of gods… who would never submit to oversight.
But then, considering one of his last storylines was all about him taking over earth acting above the law and everything pretty much going to pot as a result, I can see where this character might now better appreciate super powers under some kind of oversight.
