Señor Chaos is a Matador, working in 'El Guapo'. His first and only appearance is in the comic Ole!, published in the Cartoon Network Action Pack series, issue 2.
The Matador is shown to be very vain, aspiring to be known worldwide, as well as continually basking in the cheers of his crowd. His words as he was arrested show that his motivation was to be loved even more than he already was. Although he did try to warn Four Arms of his bull's propensity of violence towards the color red, showing some concern for his creation's rampage.
Presumably of Mexican ancestry, sporting slicked back black hair, and dressed in a traditional, blue Matador outfit with red and yellow trimmings.
When working, he wears a bright red hat, and carries with him a red cloth.
Powers and Abilities
We're lead to believe that Señor Chaos was a skilled bullfighter, being well renowned as a local celebrity even before his scheme with the robotic bull, with his act being slated as the main event.
Also shown is his technical skill in robotics, as well as making his creation indistinguishable from the real animal, even to Grey Matter, who was up close to the creation.
He has a remotely controlled robotic bull of his own creation, which near-instantly became uncontrollable, and eventually was destroyed by the Tennysons.
