Tetra

Tetra is a member of a race of aliens known as the Ancients who lead the Grey aliens. Tetra is many thousands (possibly even millions) of years old.

Tetra was the commander and overseer of the Grey spacecraft that was shot down over Shag Harbour, Nova Scotia, on October 4, 1967. They commanded to craft to be submerged and berthed off the coast of HCMS Shelburne as the craft repaired. Upon hearing that the Hybrid Sarah, who was thought to have been incinerated in the blast, had survived and was stranded on Earth, Tetra sent a small retrieval team consisting of Contrast and another Hybrid named Celeste who had been accompanying them.
