Supersonic is the boss of Deathskull.

History
In "The Staff Of Jeff" Supersonic sends Deathskull on a mission to fight Nico. He also calls Jeff about Nico coming but Jeff says he is neutral. Then the two attack Nico but she was her staff and banishes Supersonic. "Glitching" is his next appearance and during a fight between Nico and Deathskull he appears. Nico then flees to her base and the two don't enter. Then Deathskull summons a creature and Supersonic watches. The creature is hit into the sun by Nico and burns to death. Supersonic runs and Nico gets infected by Deathskull. She starts glitching and Supersonic gets shocked, she makes Deathskull a zombie and Supersonic runs. Then after Deathskull returns to normal, Nico, Deathskull, and Supersonic disappear. In The Other Dimension, Supersonic attacks Linmaar and Nico but is nearly killed by Linmaar. He tells Deathskull to chase after them. Supersonic later fights Linmaar but he is defeated. He is left in Linmaar's Dimension with Deathskull and Nico.
