Tachyons

Tachyons are an advanced race of beings created as part of the Balanced Universe Palate, which was supposed to bring balance to the universe. They stand at 10 feet tall, and Brutes stand at 15 feet tall. They rely on sheer brute force and superior technology to win their wars. They went to war with the Precursors, and failed due to the Sentinel program's success. Their race was all but absorbed into the Shade after the Precursors defeated them, since the Alpha Shade believed that they had failed him and they would do better as his servants.
