That was an interesting thought, but Donnie quickly cast it aside. Doomsday King did not possess Ancient Doomsday's ability to create Destruction Spores. His resurrection could only come through being killed again and again, then regenerating from scraps of flesh and blood. Unlike Ancient Doomsday, he could not parasitize countless lifeforms and use Destruction Spores to resurrect anywhere, anytime.
