Vada Prime was a triumvirate warrior caste made from the best genetic stock of the Robotech Masters' Tirolian Legion. Those that were lucky to be part of this select group were armed with the best equipment, as was the case during the initial deployment of the Bioroid Invid Fighter. Vada Primes were also allowed to select their genetic mate for breeding purposes. The group included Karno and his clone brothers Darsis and Sookol.
