While the Seducer made puppets, and the Fraudulent falsified its nature, Pulsus reflected all that surrounded it.

Powers: From the Twenty Primal Demons, it could be said that Pulsus was the only one that did not by its own choosing battle. As was its being and nature, the creature was void of any personal status, and merely mirrored and reflected on its body whatever it was that was around it, and its personality was not developed, but rather borrowed, from its brethren. In a primal environment of chaotic instances, where the elements themselves were battling each other, Pulsus reflected the evil from its brethren, the rock that was around it, and the fire from the Sunguards that fought it. What the Demon really looked like is a mystery, but perhaps due to it's shapeshifting powers, as well as its appropriation of elements, it never had one to begin with.

Defeat and Aftermath: Since it had no thought of its own, no patterns to understand, and no stable form and attributes, the Sunguard had difficulty battling the towering monster. In a gambling move, the Sunguard were able to draw the Demon into a position of instability, then pushing it down the Pit, a gamble that worked in their favor. Due to only being surrounded by rock, heat, and activity, falling into the frozen depths of the Pit had a powerful effect on Pulsus, and due to being all alone, it was not able to reactivate itself, reflecting in its body the ice it was surrounded by, at the same time it froze the creature to its core. Despite this, in the eons to come, Pulsus would still silently adapt its form with other lifeforms that would surge across the Cosmos.
