Tom Cat

Thomas "Tom" Cat is a fictional character and one of the two main protagonists in Metro-Goldwyn-Mayer's series of Tom and Jerry theatrical cartoon short films, created by William Hanna and Joseph Barbera. Tom is a blue/grey anthropomorphic domestic short-haired cat who first appeared in the 1940 animated short Puss Gets the Boot. Tom was originally known as "Jasper" during his debut in that short, however, beginning from his next appearance in The Midnight Snack and onwards, he is known as "Tom" or "Thomas".

Personality
Tom's personality has changed remarkably over the years, especially after the first episodes. For example, in his debut, he was quadrupedal and had normal cat intelligence. However, over the years (since the episode Dog Trouble), he has become almost completely bipedal and has human intelligence. As a slapstick cartoon character, Tom has a superhuman level of elasticity. When acting as Jerry's antagonist, Tom is usually defeated (or very rarely, killed) in the end, although there are some stories where he outwits and defeats Jerry.
