Wow. They've really bastardized Norse myhtology. Originally, the person we know as Odin was something closer to "Wotan" or "Woden". The changes came in the translations from the original texts. So he's Odin's archaic namesake....and here I thought you were being old-school about it, but he's apparently Thor's son.
Oh you didn't disappoint me. Just Marvel did.
And your battles are always tough to comment on. There's only maybe 2 people on that list I can tell you anything about, so despite my Authority knowledge I can't say who would win with any certainty. And the bios help sometimes, but most times still don't give a full knowledge of the person's power level...at least not enough of one that I feel comfortable responding.
