Simon is a fairy TV producer and was also one of the judges on Fairy Idol. In his first appearance, he was voiced by Carlos Alazraqui. He was later voiced by Simon Cowellhimself in Fairy Idol.
He is the same general size of a fairy, but instead of being scrawny, he still has a pronounced chest and face, with a large chin. His hair is violet and wavy and he has turquoise eyes. He wears a white t-shirt and blue pants.
He first appeared in Timmy TV, where he was secretly producing a TV show about Timmy's life and broadcasting it to all of Fairy World. When Timmy eventually found out, Simon offered Timmy a contract so that he could make changes to his life and increase ratings. However, when Simon goes too far, Timmy offers him a replacement show in Crocker TV, starring Denzel Crocker, which got higher ratings than Timmy TV had ever gotten.
Simon appears again during Fairy Idol, taking on the role of one of the judges to the event.
Similar to Juandissimo Magnifico and Jorgen Von Strangle, Simon shares a rather unique physique, unlike most fairies who have small bodies with thin limbs and big heads, he is quite muscular, but still have the small legs.
