There hasn't been a monster like this in an Earth town in a long time. Sometimes they try to visit, but Thor is pretty good at not letting them. This one's strange, mirror-faced and slithery. Thor - or, really, the fraction of Thor that's here facing the weird snake monster, picks up a civilian who doesn't seem able to dodge, runs to his car, sets her down, takes Mjolnir out from under the jacket on the back seat (why is Earth so allergic to warhammers these days? this is annoying and unnecessary and someone could have died!), and meets the beast head-on to shatter its mirror face as it charges him.
The mirror face doesn't shatter. So that's interesting.
