Mr. Unfit used to be part of the Nerd Clup. He is very wimpy and weak and is constantly sweating. Although weak, he is very mentally powerful, which is how he got into the Nerd Clup back in 1999. Mr. Unfit was second-best friends with Terry, who seemed to be very lonely all the time. Mr. Unfit was in charge of gathering the boron weekly for the Friday slideshow (don't ask).
Mr. Unfit was featured in the Actionfiguresinator (set 3).
