Nemo

Nemo is the titular tritagonist of the 2003 animated film, Finding Nemo and a major character in its 2016 sequel, Finding Dory. He is the son of Marlin and a clown fish, who got captured by scuba divers but then many days later was freed by a fish named Gill and reunited with his father.

He was voiced by Alexander Gould in the first film (who would later voice Bambi in Bambi 2) and Hayden Rolence in the sequel.
