Elmer Phitts

Elmer Phitts is the biological son of Donna Phitts and was kidnapped many decades ago by Bryce Tankthrust. He was put in a special machine that would keep him a baby for as long as he was in there.

He is used to create clones of him and when they are at the right age their hearts are harvested by Bryce so she could live forever. The hearts only last a few days so there are many clones of Elmer working at one of Bryce's many companies.
