The eponymous first half of the Tom and Jerry duo.

An anthropomorphic blue/greyish cartoon cat who has a perpetual rivalry with Jerry Mouse. Said rivalry is friendly/playful or otherwise, depending on the shorts (and era).

Is often depicted as being short-fused and resilient.

One of the most (if not perhaps, THE MOST) iconic, recognisable and beloved cartoon characters out there, with his (and Jerry's) fame and reputation transcending time, space, language, culture and other such barriers.
