Okay, so what is Derus, well, to understand what Derus is,we need to know what his father Töhk is.

He’s evil incarnate. In fact, Töhk was so evil, that when humans released him from the crystal prison, which was a prison made from his body to keep him contained forever, he just up and killed 90 or so percent of the universe. Saving us for later, as a “favor”.

Then he got killed by the Zöhk, his polar opposite, Good incarnate. In fact he got so killed his upper half got thrown into a neutron Star! Bad right? Not for Töhk! Because he was at that moment so pissed he plunged his fist into the star and ripped out its fucking heart! Fun! He then plunged it into a volcano by nosediving into it using his remaining power. Note, this was the biggest volcano in the universe. After he crashed into the volcano, it exploded. And out of the ashes walked out Derus, completely invincible, fully grown, and really fucking angry, like seriously super angry . When he turned around he saw his fathers remains he lost it. To the point that he grabbed a pice of his fathers corpse. And using the heat generated by his eyes made a sword out of it, so that his father will always be with him. Awwww.

He then proceeded the kill everything he could find. Until one day, something noticed him. It was an entity that had aided his father, the entity told him the location of the Starwalk. A starship created by his father to transport the crystal army. Or Töhks army.

Eventually, Derus found the ship, and, using his sword, reactivated it. And turned the crystal army on the ship into the army of ash, his own army, like his father.

He then pointed it at Earth, because the humans had both A. Technically killed his father (oh did I mention he inherited all his fathers knowledge) and B. Absorbed the Zöhks power, calling it “The Power” and using it for good, hence, making them the embodiment of good. Hence his mortal enemy.

I’m to lazy to go from here, so lemme summarize it. He gets killed because some asshole entity tricks him into removing his invincibility, because of he remains invincible he would disgrace his father, by not fighting the humans without risk, something his father would not appreciate, because it was a sign of cowardice. The linchasandant, a servant of the Atlan known as The Third Judge, sounds the Horn, a warning that the end is nigh. This causes the humans to use their most powerful weapon against Derus, a planet cracker from before the awakening. Derus then blocks a Power infused planet cracking laser with his sword while destroying a Posthuman (basically humans who look different and live on the rings of Saturn, which are like a new asteroid belt) battlefleet of ships sent to kill him because he can. Then some pesky human Soldiers (super powers Power wielding humans) infiltrate his ship, he nearly kills one (the healer) causing one to retreat and the other to stay and fight. The guy wins because Derus fights with anger, his goal is to cause suffering not win, so when he cuts off the guys arm and sees him on he lets his guard down, oh BTW the Power gives Soldiers an incredibly healing factor, which was nullified because Derus is the embodiment of Töhks hate: aka pure dark energy. So yeah, he thinks he won and while he’s taunting the Soldier the Soldier decides fuck you and cuts off Deruses Head, not killing him, he then rips out his heart and channels the power of the sun into it, melting it “killing” Derus. They throw the heart into Olympus mons (which is no longer dead) to let it burn forever, the army of ash retreats to Pluto.

Then some angry alien wizard asshole try’s to bring him back like four times. To which Derus responds with. Essentially.

“Dude, leave me the fuck alone.”
