Martian (Mars Attacks!)

Martians are intelligent carbon-based life forms featured in the 1996 film Mars Attacks!.

Biology
The Martirns' biology is similar to Humans except that, instead of breathing oxygen, they breathe nitrogen.

History
When the Martians came to Earth, they began with a peaceful approach until they saw a pigeon and immediately annihilated it with their ray guns. They immediately began attacking people, sparking a war between Mars and Earth.

At first, US President James Dale thought that the reason why the Martians were attacking was because they had a cultural misunderstanding with the Earthlings. Over time, he later discovered that it was not the case. Once a weakness involving yodeling music was discovered by Richie Norris and his grandmother Florence, all Martians on Earth were killed and the planet was saved.

Weaknesses
The Martians possess sensitive hearing, as they cannot stand the sound yodeling, superficially Slim Whitman's "Indian Love Song". Just listening to it can cause their heads to explode.
