Brittany and Victora Donnovich are the sisters of Trent Donnovich and the secondary antagonists of season 5 of Arby 'n' The Chief. They both have SPARTAN avatars with pink armor, though Brittany's has white streaks on it while Victoria's has blue streaks.
At their brothers wedding, the two greeted guests as they walked in the door, and rejected one guest because he came with an Elite avatar instead of a SPARTAN one. They were later seen talking with Brian and asking if he had ensured that Trent's wedding was going accordingly.
Later, when Master Chief and Arbiter crashed the wedding, the two piloted a falcon and shot at them. However, they were shot down by Master Chief.
Trent later mentioned that his sisters hadn't spoken to him since Bad Games went bankrupt.
