Cosmo is a character in the animated television series The Fairly OddParents who is voiced by Daran Norris. Susanne Blakeslee, on the other hand, voiced characters such as Wanda, Timmy Turner's teacher, Mrs. Crocker, and Trixie Tang. Therefore, Cosmo was not voiced by Susanne Blakeslee in The Fairly OddParents.
