Fiction

Ask Vector Prime

After MegaZarak sent Fenris and his team to Beast to steal the Ultra Matrix, Fortress responded by reverse-engineering their Pretender technology, and sending four warriors, including Eos, to stop them. Though the Decepticons managed to steal the Ultra Matrix, Eos and her teammates were able to defeat them; in gratitude, they were given the Ultra Matrix by White Leo. Ask Vector Prime, 2015/09/30

Notes

• Eos, and the other Pretenders of Primax 304.25-P3 Zeta, were based on unused concepts seen in Transformers Generations Deluxe.
• Eos (Ἠώς Ēṓs) is the deity of the dawn in Greek mythology. You may be more familiar with the name of her Roman counterpart, Aurora.
