Biography
He is one of Hecate's generals.

Season One
Rajani arrived on Earth and used the powers of the Elementalist Crystals to free her and the other generals, Oculos and Avvar, the four of them attempted to complete the ritual to revive Hecate but were stopped when Aasim was revived and scattered the crystals.

He attempts to be a mediator and keep the situation calm, specifically when Avvar and Rajani are at each other's throats.

He has come up with a plan following several failed attacks, he will impersonate a student at the girl's school and seduce one of them into becoming evil. This plan came into fruition in Act 8 when he attacked and killed Leon by swallowing him entirely, absorbing his DNA and transforming into him.

He successfully impersonated Leon and seduced Natalie, infected her with a poisonous bite that put her into a deep sleep. He was able to steal her crystal and then turn her evil with Rajani's help and magic.

In Act 16 he assisted Rajani and Oculos in attempting to steal the Pink Crystal but was beaten back by Kennedy, Rowan, and Aasim. He later returned in Act 20, taunting the girls, and was once again defeated - this time by a newly re-powered Natalie.

After Hecate's revival, he was pulled into a vortex with her, the other generals, and Aasim and the Guardians. He tormented Natalie once again, showing her an illusion of the deceased Leon and making her believe he was alive. He summoned the Thunder Titan to fight Natalie and was soon after destroyed by her.
