Mutant Enemy Productions - Name and Logo

Name and Logo

The name "Mutant Enemy" is taken from the song "And You and I" by progressive rock band Yes, of whom Whedon is a confessed fan. (On the special features of the Buffy DVDs, Whedon also says in an interview that he called his typewriter "mutant enemy".) The company's end-of-credits logo and mascot is an intentionally poorly animated vampire monster cartoon figure crossing the screen from right to left and saying, "Grr. Argh." It was drawn and voiced by Whedon himself. In certain episodes of Buffy the animation was changed:

• "Becoming, Part Two" — He says "Oooh, I need a hug" instead.
• "Amends" — He wears a Santa hat.
• "Graduation Day, Part Two" — He wears a graduation cap — the image used is a reversed logo from the U.S. national college honor society Mortar Board.
• "Once More, with Feeling" — He sings the line in falsetto.
• "Storyteller" — The monster (overdubbed by cast member Adam Busch) sings a line from the episode, "We are as Gods".
• "Chosen" — He turns and pulls a face at the viewer.

The episode "Bargaining, Part One" references the end-of-credits logo. Tara gives Giles a small rubber monster and says "And a monster. Sort of a Sunnydale souvenir, we thought. Grr. Argh." In season seven of Buffy, there is a species of ancient Vampires called "Turok-Han" or Ubervamps. They look like more detailed versions of the Mutant Enemy.

In the canonical Buffy the Vampire Slayer: Season 8 comic books, issue 22 "Swell", on page 10, the slogan for an in-comic fictional product is "Vampy Cat! Grr! Argh! He'll love you to the Santorio Corporation!"
