Shrek is the titular protagonist in the franchise of the same name. He is an ogre that lives near in his own swamp, preferring to live alone and undisturbed. The name "Shrek" is derived from the German word, Schreck, and the Yiddish word, both meaning "fright" or "terror".
He is a gigantic, green-skinned, brash and intimidating ogre with a Scottish accent who initially lived alone in a desolate swamp, feared by villagers. This changes when he is sent on a quest by Lord Farquaad to save Princess Fiona from a dragon.
