Cosmo

Cosmo is a former meet-and-greet character at Kings Island. He is one of the two title characters from the animated TV series The Fairly OddParents. Along with his wife Wanda, Cosmo was formerly a meet-and-greet character in the Nickelodeon Universe section of the park, which was since converted to Planet Snoopy in 2010, with all Nickelodeon themes being removed. He was also one of the stars of the Fairly Odd Coaster attraction, with one of the sets of cars being based on his ability to disguise himself as various inanimate objects.

Background
Cosmo is one of the main characters of The Fairly OddParents, along with his wife Wanda, and their godson, Timmy Turner. He and Wanda are fairies from Fairy World who were sent to take care of Timmy during his childhood. Cosmo is recognized primarily by his light green hair and eyes, and is known for his goofball personality. Cosmo is generally not the smartest person around, and is frequently the source of comic relief as a result. His voice is provided by Daran Norris, who also voices Timmy's biological father, Mr. Turner.

Along with Wanda and Timmy, Cosmo first debuted in The Fairly OddParents on March 30, 2001. The success of The Fairly OddParents led to Cosmo and other characters from the series making appearances outside of the show, such as numerous made-for-TV movies, various video games, and eventually the Paramount Parks, which included Kings Island.

Park Appearances
Cosmo usually appeared in the Nickeldeon Central section of the park, particularly as a meet-and-greet character in the Nickelodeon Theater when shows were not being presented. Cosmo could also be seen greeting guests alongside Wanda during the Nickelodeon Celebration Parade. When Hanna-Barbera Land was converted to Nickelodeon Universe in 2006, Cosmo's role as a meet-and-greet character was expanded, and he not only appeared in multiple live shows, but also got his own ride along with Wanda when The Beastie was rethemed to the Fairly Odd Coaster.

Cosmo would remain in the park until 2009, when Cedar Fair, who had taken over park operations in 2006, had decided to remove all Nickelodeon themes from the park. The Nickelodeon Universe area was renovated into Planet Snoopy, with the theme being changed to the characters of Charles Schulz's Peanuts comic strip. The Fairly Odd Coaster was also affected by this, and renamed Woodstock Express in 2010.
