Balpar
Balpar was a Pulsan imprisoned at the same Associates testing facility where Dr. Natalia Kasyov and Lieutenant Commander Tovar were taken. Like other Pulsans, Balpar had a massive cranium, which made him very alluring to Kasyov. Well, we're sure his personality entered into it as well. Balpar introduced Kasyov to Loborus and asked for her help plotting an escape. Kasyov and Tovar were rescued by the USS Anomaly, but Balpar was left behind at the testing facility. As Kasyov was beamed away, Balpar told her where to find the resistance against the Associates. (Domestic Tranquility [BG])
Three weeks later, Captain Reginald Bain and Kasyov returned aboard the USS Navigator to rescue Balpar and Loborus at the same time a group of Pulsans from the resistance arrived to do the same thing. At that time, Cranius informed Balpar that Balpar was now in charge because their previous leader had gone home. In addition, the group hadn't done much resisting in Balpar's absence. Balpar traveled on the Navigator and continued growing closer to Kasyov. (Transparent Motives [BG])
