He is voiced by Grant Albrect.
Dr. Locus is a stout and fairly stocky man. In his reference to his work creating robotic farm animals, he has the design of a typical farm worker. He wears dull green overalls and underneath is a white buttoned shirt. Although roughly middle-aged, Dr. Locus seems to have underwent premature balding only with two strands hair remaining, he has a curly cream yellow beard that extends all the way to his chest. Regardless of his workaholic nature, his beard is well neatly trimmed along with his eye brows. His eyes are tealish blue, he wears glasses, and has a big reddish nose.
- Locus is the final antagonist of the entire series.
- In additon to Vexus, Smytus, and Armagedroid, Dr. Locus is one Jenny's most formidable and dangerous foes. By using his engineering and intellect, he is able to manipulate, intrude without warning, and even control any robot to his own advantage using a remote control device he invented, as seen in the final episode Turncoats.
