Asgard is currently stuck in Oklahoma. But it's always been a bit iffy about whether Thor counts as off world or on simply because Asgard is pretty closely connected to the planet, normally.

The first Sentry was Kree, but I'm not entirely certain about the last one. I think he was from Earth? But last I heard, he wasn't ON Earth, so that puts him out of the running.

I think we're talking straight up brute strength in this case. Or that's where I was going with it. I think Apocalypse could count, but I...think he's dead right now? Can he die?

[Vance does keep up a bit with some of the X-Men stuff, mostly because it does affect mutants a lot and he is one. It pays to know about their villains.]
