Mortimer Mouse (simply known as Mortimer) is the overall secondary antagonist in the Mickey Mouse franchise. He is Mickey's arch-rival and second arch-nemesis (after Pete). He is a giant, anthropomorphic mouse. Unlike other mouse characters, he has two large teeth, like a rat (except in House of Mouse, where he doesn't have them). He has big feet like Goofy, and he is tall as him, with some of his appearances making him almost tall as him, or taller than him. Because of some of his rat-like traits, many characters and people mistake him for a rat. 


He loves girls, but love is just not on his side. In "House Of Mouse", it is shown that Mortimer is hated by all the guests. Even Pete is shown to dislike him. When Mortimer isn't trying to get Minnie or Daisy, he is trying to get other girls, such as the Ugly Stepsisters, Madam Mim and Ursula. The only girl he doesn't like is Clarabelle, who ironically is, the only girl who loves him.


He first appeared in Walt Disney 1936 cartoon "Mickey's Rival". He appeared in many comics where he was called Mortmorency Rodent, Mortimer Rodent or Mr. Slicker. His second cartoon appearance is in 1999 long-length cartoon Mickey's Once Upon A Christmas. He is also one of main antagonists in 1999 series Mickey Mouse Works, and he is supporting character in 2001 series House Of Mouse,where are shown Mickey Mouse Works shorts. He also appeared in "House Of Mouse: Christmas Special". He also made many appearances in 2006 series Mickey Mouse Clubhouse,with most important role in episode "Super Adventure", where he was a super-villain named Megamort who redeems himself. He also appeared in Mickey's Roadster Racers episode "Daredevil Goofy". He made two appearances in 2013 series Mickey Mouse, in episodes "No" and "Pete Scorned".
