He was once one of the Shadowreavers with Igiulaw until Wario and Waluigi killed them. He is later encountered in OiramOiram12345 and The Dark Star X and stole Tico's DNA before being killed by Wario again. He reappears more times in the movie without any major role whatsoever. In the end, he (spoilers!) was killed with all the other dopples at the end of the movie.
