Nimrel is the malevolent corruption of the wizard Merlin and an antagonist in The Mask: The Animated Series.
He was a medieval wizard who became a monster after an accident with a spell. Nimrel was also one of the wearers of the Mask of Loki and was brought from dead by the imp named Skillit to fight Stanley.
He was also promised to wear the Mask again by Skillit. Stanley managed to send Nimrel back to the Shadow Lands which foiled Skillit's plan.
- his demonic appearance seemingly but vaguely resembles the Xenomorphs from the Alien franchise.
