Evil Dr. Yequil is more or less an antagonist, even thought he´s just a kid who wants attention and seeks it by any means. Althought he´s between 10 and 12 years old, he´s a complete genius. He invents from time travelling machines to robots with A.I, and from spaceships to giant buildings in a matter of days.
The irony is that his mother thinks he´s just a standard kid, completely ignoring the giant building in their backyard and the two robots that follow him all day.
His first appearance is in "The Birthday Concert ", where he tricks The Lyosacks by telling them to play a song in a concert, when it was actually his birthday party. In this episode, Yequil competes with them, finally losing, but swearing revenge.
He appears in a lot of episodes, in some of them he´s an antagonist and in others he´s just walking around doing something. And he does this all just because he´s bored.
In Time Trouble, Yequil somehow is seen rulling the world along with Don Morettini in the future, since everything is too futuristic for the time. Yequil designed an army of robots and a pill that keeps Don Morettini alive. This time line is then erased when Alec and Ray go back to the past and "killing" the Morettinis.
- In "The Return 2", it's revealed he becomes a genius because of an experiment the aliens did to him while he was in her mother's womb. Little is known as to why the aliens wanted to create a human genius, but with the clues given in "The Abduction", we can guess it's part of their experiments to create a perfect species, since they created humans by giving their genes to apes.
- Yequil is seen making lots of things such as a robot in Yequils birthday concert, time machine in Nazi Zombies Movie and a tower in Time trouble and Mafia Wars.
- In "The Return 2" it's revealed that he is Mr. Gonzalez's son, but due to some events in the past it seems him and her mother forgot meeting each other. For now, we know she doesn't remember due to the aliens errasing her memory.
