Shrek is a disgusting overweighted ogre who was born in Inverness, Scotland in 1957. He then moved to Waterford, Ireland after he finished Worcestershire Academy in the early 1980s. In 2008 he left Waterford, Ireland and then moved to Pensacola, Florida because he had been selected to go on Main Character Judging and since he has won the award he now lives with Mario, Black Yoshi, Woody, Tony the Tiger, Mr. Pig and Toad, who now mooches off Mario by living with him without any payback. Shrek is obsessed with eating Cheesecake and taking craps. He is so obsessed with cheesecake that he literally has sex with it more than he eats it. He has eaten so much that his veins are filled with cheese, and he is obsessed to the point that murdered Toad for eating his cheesecake. Shrek also is obsessed with taking "craps" in the bathroom. He at one point even got his own sewer just to contain his crap. His obsessions lead him to wasting his entire life eating cheesecake, taking crap, and just generally being gross.
Shrek is shown to sometimes extremely cruel to just about everyone. He has shoved a corn-dog up Mario's butt, forced Mario to drink his diarrhea simply because Mario wouldn't give him toilet paper, brutally murdered Toad multiple times, threw Toad out of the house, made Toad eat his crap on multiple occasions, made an extremely hurtful and mean rap against Toad with Black Yoshi, and much more.
Shrek refers to Mario as "Donkey." In Shrek's Big Crap, he asked Mario to get him coke and he refused to give it to him. When Shrek uses up all of the toilet paper he blames Mario. For some reason, Mario hasn't kicked him out despite all the cruel things Shrek has done to him.
Shrek and Black Yoshi are seen to get along well and could be friends or in a creepy pansexual relationship. They often team up with each other (mostly to kill someone). In The Bird, Skittles, a rare African bird that Woody adopted, ate Shrek's cheesecake and McDonald's and messed with Black Yoshi's Call of Duty (which he does likes). This resulted in them teaming up to assassinate Skittles. Shrek stuffed him in a trash bag, tossed the bag to the side of the house, and had Black Yoshi shoot him. However, a news report then states that the bird was missing from the zoo and that a $20,000,000 reward will be given to anyone who can bring it back alive. In Toad is Cool, he and Black Yoshi teamed up again, but to oppose Toad and Ray Cheesey through a rap battle.
Chef Pee Pee
Shrek and Chef Pee Pee are good friends. When Mario refused to get Shrek some cheesecake, Shrek asked Chef Pee Pee to make him some. Shrek is also seen calling Chef Pee Pee multiple other names such as Chef Cock, Chef Penis, Chef Peehole, Chef Donkey and Chef Weiner. Shrek tells the Chef that he will pay him $50 an hour to make him homemade cheesecake. Chef Pee Pee agrees to do so and puts melted cheese on a Zebra Cake. Disappointed in Pee Pee's work, Shrek decides to change Chef Pee Pee's job to wiping his butt after he takes a huge crap. Chef Pee Pee refuses the job opportunity and returns to working for Bowser.
