Wobbly-Headed Bob appeared in the Johnny the Homicidal Maniac comic book. He exists in a different fictional universe and was essentially a separate one-page series within JTHM. Wobbly-Headed Bob is a depressed, conceited outcast with rodent-like features and a huge "freakishly overdeveloped" head. Bob believes himself to be the "ultimate being" as he is so smart, but is tortured by his own dark intelligence or the world's problems, and has an amazing knack for causing misery in everyone he meets. He meets cutesy, happy, ignorant, carefree characters. By showing them the horrifying reality which he perceives to be their life, Bob makes them miserable, often causing them to commit suicide, which he barely seems to notice.
