Granted, Thor does cut a slightly different silhouette than he has in everything Earth's media has broadcast of him, but a haircut and an eyepatch doesn't help hide those biceps and how they fit into his armor. The fact that he's used lightning to burn out the edges of his circle is kind of a dead giveaway, too.

Her call catches his attention, and while he doesn't recognize her at all, Thor is very used to being recognized himself. Comes with the territory when you're royalty, as well as being an Avenger, if the multitude of selfies he's participated in are any indication. She doesn't look like his typical fan, however; the leather and the spear stand out like beacons, and despite the casual position she's taken at the edge of the ring, he can tell from the way that she stands that she knows how to use them. She reminds him of the Valkyrie, to some extent.

"Training," he calls back, tightening the final strap on his vambrace as he turns to face her direction. "Gotta keep the skills sharp, you never know when you might need them, you know? Besides, it's a beautiful day." He might have something to do with that, too; it's hard to find people to fight you when it's storming out, no matter how exhilarating Thor finds it.
