Titania Prime is the long-lost wife of Optimus, having been assumed dead after she and her team failed to dismantle the Alpha. She didn't actually die; she was merely put into stasis lock for a few centuries, and when she came to she immediately sent out a distress signal, as she and her team were blocked from leaving their Earth's atmosphere. Optimus describes her wistfully, showing that he still misses her despite the centuries they've spent apart. She is resourceful, just, and more down-to-earth than her husband. Initially, there is only one Titiania, but once Whitney leads the team to a new world, she falls to the power of Alpha.
