This guy is based off of the same issue of Thor as the Bor that I made a while ago. To trick Bor into fighting Thor, Loki cast a spell on Bor that made him perceive everything he saw as a hellish version of itself, including Thor. Since this demonic looking creature that Bor saw was holding Odin's hammer, Bor assumed that he had killed Odin, and began to unleash his fury.
The cool part about this guy is that he could really stand in for a Zombie Thor too, if you're into the whole Marvel Zombies thing.
The observant may notice that the rune on his belt is reversed from how Thor wears it. This is a bit of artistic license I took, as in the comic it was placed normally. The rune is "Uruz", which when worn the direction that Thor wears it means courage, strength, wisdom, and masculinity. When reversed it becomes "Merkstave", which means weakness, callousness, violence, and domination of others.
If I were to do him again, I would probably use the SMC Hobgoblin instead, since he's much taller than the Green Goblin.
