Origin
Marvin the Martian is a cartoon character from the Looney Tunes franchise that made his debut in 1948's Merrie Melodies short "Haredevil Hare". He appears frequently throughout the franchise usually as an antagonist who wants to either capture or destroy the planet Earth for petty reasons, such as wanting a better view of Venus. Marvin is the quietest, calmest and politest of the Looney Tunes villains, and the most soft-spoken, and unlike most of the other villains, he is very clever.

Official Biography
"Where's The Kaboom? There Was Supposed To Be An Earth-Shattering Kaboom!" "Make way for an earth-shattering kaboom!"

Marvin the Martian has always had one dream in life: Conquering the universe in the name of Mars! However, no matter how hard he schemes, no matter how much he plans, he always seems to end up thwarted by none other than Bugs Bunny, a simple Earth rabbit. Over the years, Earth has continued to be a thorn in his side that he has vowed to eliminate, but he can never quite seem to make it stick...

Default Variant
Marvin's default look seems to be based on his design from the 2019 Looney Tunes Cartoons animated series.

Trivia
