Señor Senior, Junior

Señor Senior, Junior is a vain man-child with little to no interest in being a villain. While he generally goes along with his father's evil plans and has even attempted a couple jobs himself, he is usually too busy maintaining his tan and becoming a pop star to concern himself with world domination schemes.

Junior's first appearance is in the episode "The New Ron". Nestor Carbonell provides his voice.

History
Junior and his dad live on a fairly intimidating private island, somewhere off the coast of Europe. Kim first encountered them when Junior's giant tanning lamp was causing rolling blackouts across Western Europe. Upon going to their island and realizing that Senior didn't mean any harm, she gave him a lecture about energy conservation and let him be.

Unfortunately, during that same encounter, Ron commented that several features of Senior's island bore strong resemblance to a villainous lair, and gave him more suggestions for making his home more villain-worthy (Spinning tops of doom, self-activating lasers, speedboat for quick escapes, etc.). Senior originally dismisses Ron's suggestions, saying that they sound too sinister, but upon reflection, he decides that he needs a new hobby, and pretty much drags poor Junior along for the ride for the rest of the series.

Description
Junior is, for the most part, interested only in himself. If he put his mind to it, he would likely be a better villain than his father, as he favors simple solutions over more complex "traditional" schemes, but he is also extremely lazy. His dream is to become a pop star, although it is shown in several episodes that he has no musical talent.

Junior wears a tight yellow t-shirt with a red belt and tight black pants.
