Nightcaster Arkvarius II was the Ledgerdomain-born half-Anodite, half-Oneiromancer, hell bent on destroying Azmuth as was his father's goal. He appears in Back in Action: Alien Universe.
He first appeared in Hit and Miss.
Back in Action: Alien Universe[]
- In Hit and Miss, he battled his way into Azmuth's headquarters on Galvan Mark II and kidnapped him as Ben was unable to stop him. He later left a hypnotized, transformed version of Eunice fight Ben in his place.
- In Ten Plus Twenty, he fought Ben in the middle of Downtown Bellwood and lost at the hand of both Obsorber and Nigester, who was removed from the Omnitrix for being a possible gateway for Nightcaster back to life. He was accidentally killed by Ben in the same episode when Nigester dealt a powerful blow to his fragile body.
Appearances[]
- Hit and Miss (first appearance)
- Ten Plus Twenty (final appearance; killed)
Trivia[]
- Nightcaster II takes after his father's Oneiromancer side more than his brother since his body proved to be far more fragile in his final battle with Ben.
- Because Oneiromancers reproduce asexually, he is technically a genetic clone of his father.
