He may serve Morgana now, but his heart remembers only you.

The witch who tried to save his soul.

Angor Rot x witch user!

....

As a troll victim of Gunmar's war, Angor sought power to protect his people. Thus, Angor made a deal with the evil legendary hag Morgana who granted him great magical power in exchange for his soul. The witch, however, took advantage of it by transferring his soul into the Inferna Copula, a ring with which she could control Angor Rot before ordering Angor to seek out and assassinate Merlin's champions.

For hundreds of years, Angor Rot would kill countless Trollhunters, harvesting their souls to fill the void of not having his own, which is said to be a fate worse than death.

....

Angor Rot has strong, muscular arms and a wide chest, giving him an almost human-like build. His tall, slender head is shaped like a skull. Its pair of luminous, sunken yellow eyes with black sclera—which are detachable and capable of independent movement—are the creature's most recognizable characteristic. His eyes turned pale white after accidentally destroying the Inferna Copula (and his soul with it) in "It's About Time". The back of Angor's head has two gigantic horns that grow out and curve around it; the horns themselves seem to be covered in some kind of cloth. Angor has an underbite, like most of the other trolls in the series, but he has a considerably smaller nose. He possesses teeth and fangs, vines growing out of his torso and feet, a black nose, and blue jewels hidden in his breast fractures.

He carries a pouch on his right side and a loincloth around his waist that is fastened with a belt. From the belt, a solitary leather strap extends over his chest. His body is covered with countless roots that seem to be emerging from various fissures and holes in his stone-grey skin. The only gear on his left arm is two golden rings at his wrist, a pale-white pauldron on his right shoulder, and a leather vambrace (forearm guard) on his right forearm.

Angor Rot is a fearsome, murderous, violent, diabolical, and sadistic troll assassin who takes great joy in the casual hunting and killing of his victims. He especially enjoys playing a deadly game of cat-and-mouse with his prey. He is also described as unpredictable by Vendel, as he can strike at any time or start manipulating his prey. He is also very cunning, intelligent, and manipulative, using his brains and booby traps to his advantage, rather than using brawn. He initially used to be a caring individual who wished only to protect his people and his land ever since Gunmar and his army attacked and probably destroyed his land.

This led him to his deal with the Pale Lady (Morgana), and his powers. However, after being tricked into giving up his soul in exchange for his wizardry, any sympathetic side of him outright died off, as it consequently turned him into an unpleasant, heartless, bloodthirsty, ruthless, brutal, treacherous, and destructive monster who has caused numerous destruction and chaos throughout his time, even killing some past Trollhunters as well. After being released from his imprisonment by Stricklander, he is noticeably calmer, patient, and stoic, almost playing with Stricklander and his fear of being killed by the Trollhunters, even after he was forced to work for him after Stricklander wore the Inferna Copula, where his soul is stored. His attempts, just to name a few, include, him sending out Pixies to bring out Stricklander's fear of Bular and his revenge for allowing Gunmar to "rot in the Darklands".

Another example is when he calmly threatens to cut off his finger after he states that as long as he wears the ring, he can always control him: "But how long will that finger be on your hand?" After he accidentally destroys his own soul, he becomes more soulless, uncontrollable, barbaric, vicious, obstreperous, temperamental, deranged, vengeful, and especially psychotic to all he meets, as he attempted to kill Stricklander in a fit of animalistic rage; at the same time, he vowed that after he kills him, he will then kill Jim and "everybody else". When asked if he is insane, he states, in an unstable fashion, "I'm free!" The only thing that does remain is his cunning, unpredictability, and sadism, as he gleefully stated that the only reason that Jim is still alive is that he let his loved ones fall in his place and that because of this, he let AAARRRGGHH!!! die. He is also shown to be arrogant, boastful, and prideful, as he bragged to Jim, "where are your loved ones now?", only to end up killed seconds later.

In the third season, when he was revived, he noticeably lost a large amount of his cruelty, yet still retained sadistic, manipulative, and destructive regardless. He silently questioned his role as Morgana's "champion", and was outright horrified when Morgana killed most of Gunmar's troops for the Eternal Night. He also convicted Gunmar to let Draal live upon seeing him being called a dog, which made him reflect on his enslavement by Stricklander.

While battling the now hybrid human-troll, Jim, the latter reminded Angor that he was a great warrior and hero and told him what his purpose was now that he was revived, causing Angor to remember what really happened to him. Upon realizing who he really is, Angor betrays Morgana and sacrifices himself to make sure she was defeated for good.
