Editing Mutant Enemy (section)

===Original end-of-credits logo===

The company's [[production logo|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 (Buffy episode)|Once More, with Feeling]]": He sings the line in [[falsetto]].
* "[[Storyteller (Buffy episode)|Storyteller]]": The monster (overdubbed by cast member [[Adam Busch]]) sings a line from the episode, "We are as Gods".
* "[[Chosen (Buffy episode)|Chosen]]": He turns and pulls a face at the viewer.

The episode "[[Bargaining, Part One]]" references the end-of-credits logo. [[Tara Maclay|Tara]] gives [[Rupert Giles|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 <obscured> the Santorio Corporation!"

====Parodies====
At the end of the credits of the animated sketch comedy parody show ''[[Robot Chicken]]'', a parody of the Mutant Enemy, Inc. logo appeared with Joss Whedon (guest starring as himself) providing the "Grr... Argh..." As the enemy mutant rips apart the city, the scene cuts to an office where Joss Whedon is playing with dolls and an executive says to him, "Come on Joss, that's why you got kicked off ''[[Wonder Woman in other media#Undeveloped and abandoned projects|Wonder Woman]]''."
