Fairly Goth Parents - Trixie Tang - Virus

In the episode "Virus R' Us", Trixie was bitten by a Virus known as "Corruption.BAT". A powerful Virus capable of destroying Computers and Machines alike. When bit, Trixie began to feel an incredibly painful transformation, allowing her to change from Human to Virus on a whim. Other powers she gained were;

Mind control to any and all viruses
Absorb all corrupted or viral data
Travel from computer to computer
And it gave her the ability to speak in Virus and Binary Code.

She used her Virus powers to stop Corruption.BAT from destroying the world's machines via the Internet and later placed it under Quarantine after restoring her Computer's Anti-Virus program.
