Captain Louie

Captain Louie is a character in the Pikmin series who first appeared in Pikmin 2 for the Gamecube. He is Captain Olimar's assistant, and is considered to be clumsy.

Name
His name is thought to resemble Luigi's (from the Mario series.) name. Not only does it look the same, but Mario's name is similar to Olimar's, which can further make this fact.
