IC-4447

Ennen was a Clone commando and a member of Galaar Squad, trained by an unidentified non-Mandalorian Corellian sergeant from the Cuy'val Dar.

After Order-66 was enacted and Palpatine established the Galactic Empire, Galaar Squad was disbanded and Ennen, along with squadmate Bry, were the only two who survived. They were combined with Omega Squad's Niner and Darman Skirata to form Squad 40 of the 501st Legion. On their first mission as a squad, they were sent to the planet Celen to capture Jilam Kester, an Antarian Ranger who was helping Jedi escape capture from the Empire. Upon storming the building where Kester was residing, the commandos came face to face with Jedi Master Iri Camas, who previously commanded the Special Operations Brigade. Camas distracted the commandos, allowing Kester to escape, and ended his own life by igniting a gas line and causing the building to explode. Bry died in the explosion while the rest of his squad managed to escape.
