Lazlo is an eccentric Brazilian spider monkey. Often annoying to Lumpus, he is a very happy-go lucky monkey. As a hippie, Lazlo loves peace. Lazlo has a serious case of Coulrophobia. Lazlo "goes where the wind blows" by his own statement. He is the main protagonist/hero of the series. Carlos Alazraqui voiced Lazlo (Like Rocko from "Rocko's Modern Life").
Seth Benedetto Joseph Romero Brandon Lopez Toro and Ishmael Mendoza, creators of Camp Lazlo, originally created Lazlo for a children's books concept. As he developed the concept, Benedetto Romero Lopez Toro and Mendoza believed that a children's books could not contain the stories and the ideas, so he decided to create a television show. According to Benedetto Romero Lopez Toro and Mendoza, when he thought about Lazlo's personality, a spider monkey came to his mind.
Lazlo comes from Brazil. Benedetto Romero Lopez Toro and Mendoza wrote on his website that Lazlo's parents moved to the U.S. to start a local store, allowing Lazlo to learn English, French, Spanish, Korean, Japanese, Swedish, and Mandarin. Originally Benedetto Romero Lopez Toro and Mendoza wanted Lazlo to carry a strong Brazilian accent, but when Cartoon Network TV Shows asked Benedetto Romero Lopez Toro and Mendoza to choose only one character to carry a strong accent, Benedetto Romero Lopez Toro and Mendoza opted Raj and gave Lazlo an Americanized voice. Benedetto Romero Lopez Toro and Mendoza said that they did not plan Michael Angelis to voice Lazlo; according to him the arrangement simply occurred.
