O'Sullivan was in charge the Anaheim Electronics office on the moon at the city of Von Braun. Outwardly, he supported the Federation, but was also more than happy to deal with their enemies, including Cima Garahau, for the sake of business. His motives were greed and the desire for greater independence for the moon.
Following the outcome of Operation Stardust, O'Sullivan was found in his office dead, having shot himself in the head rather than be arrested for his implications with the Zeon uprising.
