Otis is a black and white male cow who is the leader of the barnyard. Although male, he is called a "cow" not because he is one but because of his udders, the fact that he is male despite being a cow is not explained in the series. He is the show's lead protagonist. In the episode "Cowman and Ratboy", Otis becomes a superhero named Cowman. He also appears as Cowman in the special 1-hour episode "Cowman, the Uddered Avenger". Otis is also a huge party animal (no pun intended) and enjoys anything with action or stunts and enjoys watching sports bloopers. He has a big crush on Abby. Some of his other aliases are "Professor Exposition", politician "Ned Bovine", newsman "Gil O'Malley", golfer Heifer Woods (punning off the famous golf star Tiger Woods) along with many other human disguises, and in the show's Christmas special, we learn he went to high school with two of Santa Claus' reindeer, Donner and Blitzen. He also plays a lot of pranks on Nora Beady (their next door neighbor, who claims to hear them talking and having their wild parties).
