Joanna Cargill, also known as Frenzy, is a fiction character, a mutant superhuman in the Marvel Comics universe. She has been a member of supervillain groups, including the Alliance of Evil and the Acolytes, as well as the superhero team the X-Men.
Frenzy first appeared in X-Factor #4 (May 1986) as a member of the Alliance of Evil, and was created by Bob Layton and Keith Pollard.
