Once a simple skull spider, Doomra's life changed course when he came in contact with a pool of energized protodermis. No longer a skull spider, the first thing that he realized was that he was no longer bound to the golden skull spider mask. The second thing that he realized was the hunger for power. And so he traveled the land of Okoto searching for power, in any shape that it presented itself. Following his thirst for power, he came upon something more powerful than anything else he had beheld, the Nuva sword. Upon finding that he could not absorb it, he decided that no one else could have it. And so he dwelt ever in the darkness waiting for someone to come and claim his prize, as he knew they would try, and they would fail.
