it's my headcanon because Odin did some crazy things after he was brought back from the dead.
in Agent of Asgard, Odin couldn't use the Odinforce or something because it was almost fully depleted or something and Freya asked Odin if Odinforce was charged up or something.I don't understand your statement about Agent of Asgard
Where in Original Sin is that? I read the whole series and I don't recall. Was that in the Tenth Realm mini?
as for Original Sin, during Asgard vs Heven war, it was a stalemate until Odin's power rose up when he got pissed which is weird why he didn't do it immediately so I took it that he wasn't at 100% until the Queen of Angels killed his daughter.
