Martian (El marciano, 1970)

Martians are a humanoid species from Mars, who showed indiscriminate hostility towards Humans.

Biology
Martians are humanoids with a mostly Human-like body shape. However, they have light green skin and a taller cranium than Humans, with a ridge in the middle of their larger forehead, and dark hair. Additional features include a protruding chin and large, semi-pointed ears with large earlobes. Despite evolving in the Martian environment, they are perfectly capable of surviving in Earth's environment.

Culture and society
Little is known of Martian society, other than they appear hostile towards Humans, sending one-man invasion forces to Human establishments, although the Martians in question do not use lethal force, implying that they want to capture Humans alive. Martians, or at least their soldiers, wear dull silver jumpsuits with a metal collar, likely for a helmet, with black gloves, reflective silver boots, and a thin grey belt. The Martian language is identical to Spanish.
