Trunt Harval is the Nivelian leader and the primary antagonist in the Supernova add-on. He assumed political leadership at the same time the supernova event took place. When he first met with Keith T. Maxwell, they shared notes on the stealth fighters. He reported falsely to Keith that they also saw these stealth fighters in the Nivelian borders. He was surprised to see that Keith killed a few of them, and said it was 'good news'. He also kidnapped the Midorian refugees and planned to use them as soldiers. He was responsible for inducing the artificial Supernova in the Ginoya system. He was killed at the end of the Supernova storyline by Keith T. Maxwell.
