Marvin The Martian is a Looney Tunes  villain, created, much like Yosemite Sam, out of the need to make a challenging foe for the ever-tricky rabbit known as Bugs Bunny. While Elmer Fudd was considered too dim-witted to be a threat and Yosemite Sam was quickly becoming just as hopless, so the creators of Looney Tunes felt the time had come for Bugs Bunny to meet a new kind of villain altogether, a villain who is both very clever and who posed a true threat.

Thus the alien menace known as Marvin The Martian was born, being a more calculating and dangerous opponent than those that came before him he nevertheless found himself defeated in the end by Bugs Bunny - though due to his popularity he returned and has stayed on as one of the Looney Tune's most popular villains, appearing in many cartoons and films as well as countless merchandise, Marvin has even been adopted as the mascot of a few NASA vehicles among other things.

Marvin is depicted as a strange humanoid dressed in a vaguely Roman-style suit with a pair of oversized sneakers, this designed 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.
