A bizarre, mysterious, alleged alien entity that was first encountered by Everett “Carl” Higdon Jr in Medicine Bow National Forest, Wyoming, USA on October 25, 1974.

Ausdo One is a thin, 6'0 bipedal alien humanoid wearing a black full-body suit akin to that of a scuba diver. Crossing over his chest were two straps similar to bandoliers; this was accompanied by a belt decorated with a yellow six-pointed star buckle that encircled the waist and an unidentified insignia.

He also has yellowish skin, no neck, no detectable ears, small eyes with no brows and the dome of his skull is covered with incredibly coarse hair, almost as if he had straw growing out of his head.

His facial-features are rather disconcerting, consisting of a thin lipless mouth containing three large blocky teeth on each jaw, no discernible chin, and a pair of rigid antennae on his forehead. Instead of a right hand, Ausso One possessed a prosthesis that resemble an enormous drill and didn't have a left hand at all.

Ausso One is also pilots a cube shaped spacecraft without doors or windows.

He claims that his homeworld is 163,000 lightmiles (not lightyears away from earth, all the oceans on his world are yellow and the fish are all dead. He and his people come to earth to hunt for animals like elk and fish to convert them into food in the form of pills. He and his people wear black suits to protect them from the sun. They also occasionally bring humans back to their world for breeding programs.

Ausso One seems to have telepathy and control over gravity.

"How you doin'?"

"Are you hungry?"

"Your sun burns us."

"Do you want to come along?"
