OK, so Thor is the Norse god of legend. He’s Odin’s son, Loki’s step-brother, all that nonsense. Here’s the tricky part: originally, in the comics, Thor was also a dude named Dr. Donald Blake. Or rather, he thought that he was also Blake. I’ll come back to that. Anyway, Blake is out for a walk one day and gets trapped in a cave where he finds an old stick. Blake (who walks with a limp) takes the stick and tries to use it a lever to move a heavy rock, fails, and then whacks the stick on the ground in frustration. BOOM. The stick becomes Mjolnir and Blake becomes Thor. Then he fights rock monsters from Saturn and everybody agrees that he’s rad enough to stick around.
