Tramp

The Tramp is the male protagonist from Disney's 1955 animated film Lady and the Tramp, as well as the tritagonist in the sequel. He was voiced by Larry Roberts in his debut, and later was voiced by Jeff Bennett in the sequel, Lady and the Tramp II: Scamp's Adventure.

Development
In early script versions, Tramp was called Homer and although he was first conceived as Lady's suitor, he ended up as her ex-dog pound mate in the final 1943 storyboard pitch. A few years after that version  was scrapped, Walt read a story called "Happy Dan the Cynical Dog" in Cosmopolatin Magazine and decided that such a character as him was just was was needed to enhance the film. Before settling on Tramp, which was Walt's originally suggested name, the animators first called him Rags, and then Bozo.

Design
Tramp is a medium sized, scruffy looking dog. He is mostly dark gray with lighter gray muzzle and stomach. After he is taken in by Jim Dear and Darling, he wears a red collar with a diamond shaped license.

Personality
In the first film, Tramp is a very laid-back character. He prefers to live, in his own words, "footloose and collar-free." It's implied that he is flirtatious, given his history of multiple girlfriends. He is known for his street smarts, able to both avoid dog catchers and deal with junkyard dogs. In the sequel, he has become used to home living, but still retains his street smarts. He is also portrayed as being a loving, yet firm father to his and Lady's puppies.

Lady and the Tramp
Tramp is introduced as a stray mutt, who overhears Jock and Trusty attempting to explain what a baby is to Lady. Tramp gives his opinion on the matter, which is somewhat negative. Annoyed with Tramp, Jock and Trusty order him out of the yard.

Later on, Tramp rescues Lady, whom he calls "Pidge" from a pack of junkyard dogs. Lady reveals that she has been muzzled, and so Tramp attempts to help her take it off. He takes her to the local zoo, when he is able to manipulate a beaver into removing the device, by claiming it will help the beaver haul logs. That night, Tramp takes Lady out for a night on the town. he reveals that he goes to different houses each for scraps, and that he has a different name at every one of them. That night, he takes Lady to a small Italian restaurant, where they are served spaghetti and meatballs by the owner, Tony. Tramp takes Lady home, but on the way back, she is picked up by the dog catcher.

After he finds Lady, who has been released from the pound, he attempts to apologize. However, an angered Lady confronts him on rumors she heard at the pound regarding Tramp's multiple past girlfriends. She orders him to leave, which Tramp sadly does. However, he soon hears Lady barking furiously and rushes back. Lady reveals that a rat has gotten into the baby's room, and so Tramp rushes to stop it. He is able to successfully kill the rat, but is found by Aunt Sarah. She calls the dogcatcher to take him to the pound. However, Tramp is released due to the combined efforts of Jock and Trusty, who had overheard the humans talking after they discovered that rat that Tramp had killed.

The next Christmas, it's revealed that Tramp has been made a member of the family by Jim Dear and Darling. He has become the father of 4 puppies: 3 girls that look like Lady, and a son that resembles him.

Later on, Scamp runs away from home and Tramp blames himself for his son leaving home because he was too harsh with him. After Scamp joins a dog pack known as the "Junkyard Dogs", Scamp learns of his father's infamous reputation. Unknown to Scamp, the pack's leader, Buster, was once Tramp's protege, and now seeks revenge on Tramp. Buster later learns that Scamp is his son.

When Scamp is asked by Buster to steal a chicken from his family's picnic, Tramp soon arrives and confronts Scamp on his behavior. He asks Scamp to come home, but Scamp refuses. However, later that night, a young stray (Angel) arrives and tells him and Lady that Scamp is in trouble. He and Angel race to the dog pound and Tramp saves Scamp from getting killed by a vicious pitbull named Reggie.
