wanting to be rid of him, darkseid's omega beams randomly teleport doomsday to asgard. after feeling slightly confused, he sees some rock troll and starts attacking them.the trolls gets easily crushed and doomsday sets his sights on the golden asgardian kingdom.
odin's omniscience detects the threat and the asgardians prepare for war. after the first wave of asgardians get destroyed, tyr suggests odin unleash the destroyer.
----------------
destroyer can be possessed by any and all asgardians if need be including odin himself.
and doomsday is at his best regardless of the name or whatever.
fight is in asgard but can spill over to anywhere as fights of this nature usually do.
Doomsday, [from DD-Wars], was H/P DD with the intellect of Brainiac. He'd have the best shot, imo. However, I just don't see how he could beat the Destroyer animated by Odin.
