Malaki was a Zaldan Starfleet Officer serving in Starfleet during the 24th century. By 2364 he was serving as the USS Vigilant's Navigation Officer.
During the battle that destroyed the ship, the Conn console exploded, shredding his hands and the delicate webbing in between his fingers. After the battle, in an escape pod, Gedna Tachion used his own sleeves to bandage Malaki's hands.
By 2371 he was the Executive Officer of the USS Hornblower.
