The Mighty Thor(1991) #435

Thor II and the Asgardians make a plan to free Odin from Annihilus. Thor II doesn’t understand their warriors' code and does whatever is necessary to win, which the Asgardians find distasteful. They manage to free Odin and seemingly kill Annihilus. Annihilus was able to drain some of Odin’s lifeforce into his Cosmic Control Rod. Heimdall gives Thor II a clue to Thor’s whereabouts before sending him back to Earth.
