Cyberskull - the living computer virus

Cyberskull was a villain that appeared in the cartoon series "Mighty Max".
He was a programmer who merged with the virus he was creating, becoming able to alter reality and becoming pure electricity. He immediately set out to destroy Mega Corp, the company founded by the man whom he believed had stolen his ideas. Max was able to stop Cyberskull's first attempt at domination by using his video game skills. Cyberskull returned later, however, and attempted to create a physical body for himself by mentally controlling several prominent figures, including the head of Mega Corp.
