Obsim was a male Invid who worked as chief scientist within the armies of the Regent.
He was stationed in a laboratory on his masters starship and greeted the Regent following his return from the surface of Tirol. Obsim reported that there were no traces of the Flower of Life on the Robotech Masters homeworld and that the native Tirolian population were ill fit to serve as slaves. With the failure in his mission, the Regent tasked Obsim to serve as his lieutenant whilst his master returned to Optera in order to save face from the Regess.
Obsim claimed he was honored and that he would sift through Tirol for signs of the Protoculture Matrix. In response, the Regent said success would bring about a reward and failure would mean Obsim relegated to remain on Tirol for eternity.
