Obsessed with robots and electronics of all kinds, to the point of considering biological lifeforms to be vermin, Otto Maton replaced his body parts, one-by-one, with robotic parts, until all that remained of his human body was his head.
Dubbing himself Dr. Droid, he's gone on to terrorize Anaheim with robots and technology of his own design, including a HAL-like computer called "J76412" that can control all other electronics in its radio-wave range, lifelike female androids collectively named "Drena," and a new, more powerful arachnid-like body for himself (which is ultimately destroyed by the Ducks).
