A Ukaldian
The Ukaldians are a species of squat, thin-limbed aliens from the planet Ukal, located near the Tund System. Their bodies are short in stature and covered with green skin. They have no neck or shoulders, as most humanoids do, and their faces seem to make up their entire torso. When United Earth scouts first made contact with the Ukaldian race in 2575, they were unable to comprehend the visitors from the stars, and their civilization was thrown into turmoil. International wars erupted, much to the dismay of the scouts, who had been led to believe the Ukaldians were peaceful. After many weeks, the Republic was able to re-establish contact with the Ukaldians, realizing that the sudden appearance of aliens triggered a fight-or-flight instinct in the Ukaldian people. Eventually, the Ukaldians agreed to join the galactic community, after realizing that alien races weren't something to fear. The Ukaldians quickly adopted the technology of the Republic, and began to colonize nearby worlds. Modern Ukaldians were forced to flee Ukal when an environmental disaster left the planet uninhabitable.
