Tarkan

Tarkans were a race of green-skinned giants native to the planet Morobas. They were the hated enemy of the Morobi people, to the extent that the Jedi stationed at Morobas often had to act as peacekeepers to prevent the two races from starting war against each other. Though the Morobi viewed the Tarkans as ignorant brutes, the average Tarkan possessed about the same intelligence as the average Morobi.

Behind the scenes
The Tarkans were loosely based on the Green Martians from ' Martian stories, and were named for Tars Tarkas, one of the prominent Green characters in the series.
