Marvin The Martian

Marvin hails from the planet Mars but is often found elsewhere, travelling on the Martian Maggot or other ships. He is often accompanied by his dog K-9, and sometimes by other creatures (one gag, first used in "Hare-Way to the Stars", being candy-sized "Instant Martians" that become full-size on addition of drops of water).

Appearance: Marvin is depicted as an unusual humanoid dressed in a red (green in his final two Golden Era appearances) unitard underneath a vaguely Roman-style suit and a pair of oversized white sneakers, this design was chosen due to Mars being the name of the Roman god of war and has served him well as it makes him stand out from the crowd as a distinctive villain. Chuck Jones, who directed most of his shorts, stated that he based Marvin's blank black face on black ants, which he found scary.
