Grimm (voiced by Deven Christian Mack) – A young, talented male mid-level Astromancer who is stationed in the palace. He becomes the Mysticons' new instructor in mystical abilities. He has romantic feelings for Arkayna, which are expressed somewhat when he admitted that he was scared that he might lose her. Unlike top-level Astromancers, his exceptionally powerful innate magical aura is colored light orange; the same as his aunt Geraldine Yaga. He is the love interest and starmate of Princess Arkayna. Douglaphius "Doug" Hadderstorm (voiced by Doug Hadders) – A large cyclops Astromancer and friend of Malvaron. He becomes Malvaron's assistant in training the new Mysticons. He has an obsession with a tiny child's collectible called "Twinkly Mare" and "Twinkly Dragon". Even though he is in the Order of the Astromancers, he seems to possess no magical abilities whatsoever, which he himself officially confirms in The Secret of the Fifth Mysticon chapter book of not having any "flashy powers." He goes by "Doug" for short. Queen Necrafa (voiced by Valerie Buhagiar) – Leader and witch queen of the sinister Spectral Hand who was defeated by the original Mysticons a thousand years ago. Dreadbane intends to resurrect her with the Dragon Disk, though it is later implied she is imprisoned in another dimension that Dreadbane intends to breach. Once she is released, she double-crosses her devoted general by hurling him into the dark world where she was trapped. She similarly uses the Codex, draining its magic to rejuvenate herself and amplify her power, before hurling it through the gateway. Necrafa doubts Tazma's word that there are new Mysticons, and regards them as mere children when she confronts them in Drake City. Necrafa joins with the Spectral Dragon but is destroyed by Arkayna and Zarya who bonded together and turned into twin dragons. However, a fragment of the skeletal mask she wore is left behind. It is revealed that she was originally a powerful elf, highly gifted in ancient elf magics, whose entire being was fully consumed by the mask of the Spectral Hand, turning her into undead lich-queen of pure evilness. This implies that she is/was distantly related to Piper. General Reginald Bane "Dreadbane" (voiced by Deven Christian Mack) – The undead leader of the skeleton army who loves Necrafa and seeks to steal the Dragon Disk to resurrect her. He eventually succeeds but she rejects his feelings and hurls him into
