Louis ‘the brain’ Mayer is a member of the Harlem Heroes and Harlem Hellcats (in the story Inferno), from the pages of 2000AD.
After the crash that nearly wiped out the Heroes (2000AD prog 1), Louis is reduced to a brain in a jar, but when the Harlem Hellcats are formed (in the second Heroes story ‘Inferno’ by Tom Tully and Massimo Belardinelli), Louis is given a cyborg body and joins the team.
