Odinsleep (Yost Universe)

The Odinsleep is Odin's long slumber that replenishes his OdinForce power every year. He only awakens as his powers was replenished once again.

However, the Odinsleep had brought some advantages to the enemies of Asgard to take the opportunity to take over Asgard while its king was alseep.

So then on, all of Asgard's warriors and heroes including Thor must know protect him at all costs from the dark forces until their AllFather has awoken again every year which frustrates Thor who rather fight a real battle on Midgard than fight the same battle every year.
