Kanewisher was a member of the Dark Legion. He was one of the numerous Echidnas that was captured by the Eggman Empire and killed from the prolonged exposure to the Egg Grape Chambers. (StH: #141)

Writer Jon Gray stated in a private Q & A that Kanewisher was actually supposed to be named after his best friend's last name "Kanenwisher", but "was misspelled as Kanewisher for whatever goofy claptrap reason anyway making it all moot."
