Wolf (sometimes known as Big Bad Wolf) is one of the characters in the Shrek series. He is loosely based on the character of the same name voiced by Aron Warner. He is very laid-back, which makes him appear quite lazy, although he is a very busy wolf. He is also apparently on good terms with the Three Little Pigs.
In the first film, he was seen in Shrek's bed and pointing to another man when Shrek asked where "this Farquaad guy is". At the end, he sang "Who Let The Dogs Out" in the karaoke Shrek and the Swamp dance party.
In the second film, he had a far bigger part than in any of the others. He first appeared in Fiona's Dragon Keep in her bed reading "Pork Illustrated" with a picture of a pig in near to nothing on the front cover. He then told Prince Charming that Fiona was on her honeymoon. He also helped Shrek and the others stop Fiona from falling for Charming and defeat the Fairy Godmother. At the end, he sang "Hungry Like The Wolf" with The Three Little Pigs in front of Shrek, Fiona, and Simon Cowell.
Shrek The Third
In the third film, he appeared at Fiona's baby shower and, along with Gingy, The Three Little Pigs, Pinocchio, and The Three Blind Mice, gave Fiona a gift. He then helped save Shrek from being killed by getting in dressed as a bear.
He appeared in Shrek the Halls to celebrate Christmas with all the other fairytale creatures who all accidentally made Shrek's Christmas a disaster. He was the first to forgive Shrek because of him not bothered attitude and because he was hungry. When everyone forgave him, they all went back to the house where he kicked Pinocchio out of his "good spot".
Shrek Forever After
When Shrek enters the alternate reality, Wolfie was Rumplestiltskin's Wig handler and he was dressed as a maid. He also had a brief appearance at the birthday party of the Orge triplets, blowing up balloons but accidentally popping them when blowing too hard.
Video Game Appearances
In Shrek: Reekin' Havoc, Wolf appears as one of the bosses.
Big Bad Wolf is a playable character in Shrek Super Slam, although, he does not wear his regular pink, instead his gown colours are red, blue, green, and yellow, but in the video game intro he is shown wearing the pink gown. It could have been the beta version of the character. His slam is huffing in pair and puffing it out, the direction of the blow can be controlled.
