Shrek

Shrek is a powerful figure from German mythology. He is depicted by Mike Meyers in the famous 2001 film that bears his name, which generated

three sequels, all depicting different feats allegedly performed by the figure. Historians are uncertain whether or not Shrek literally performed a number of the actions accredited to him, or if it's all metaphorical, although almost all of mainstream modern academia now believes he existed in some shape or form.

The entirety of Hausen in da Haus famously occured in the mind of Shrek.
