|Powers and Abilities||Rejuvenates Odin|
Odinsleep is a yearly event where the Allfather of Asgard recharges his power.
To maintain the immense power required to protect his kingdom, the Allfather, in this case Odin, must spend a relatively brief period "sleeping."
During this time, the Allfather becomes extremely vulnerable and can be easily killed. The Allfather tasks the rest of Asgard with his protection in order to prevent Ragnarok.
During each Odinsleep, the enemies of Asgard gather together and lay siege to the city. It is up to the Asgardians to not only defend the Allfather but their home as well. They are often attacked by combinations of trolls, giants, Frost Giants, dark elves, and demons.
Over time, Odin's son Thor became disgruntled with having to repeat the cycle.
The Loki-controlled-Hulk attacked Asgard and fought Thor. However, Hulk's own personality overpowered Loki and he broke free. Hulk, without Bruce or Loki, was pure rage and nearly killed Thor.
He was about to strike down Odin in his Odinsleep but was stopped by Hela. When Hulk and Bruce were once again merged, Hela sent him back to Midgard. Odin then woke, fully charged.
Afterwards, he thanked Bruce for his sacrifice in helping to save Asgard.
First animated version of this state.
In the Comics
The name changes depending on who has the Allfather's power. For example, it became Thorsleep when Odin died and Thor became the Allfather.
