Lost Comrade

The war for Cybertron has proved futile as the planet is dying. Ursa Pax, an elite guard for Alpha Trion, was Persephone Jackson in her past life. Before she was captured by the 'Cons, Trion made Ursa the last of the Primes designated with the name Ultima Prime. She manages to escape the 'Cons and land on a planet called Earth. She had come to call it home over the ten years she spent there. But what she didn't know was that her twin and his crew were also there. Being friends with Raf, Miko, and Jack, what happens when she recognizes the Autobots, one by one? How does the crew react?

I do not own TFP. I only own Ursa/Ultima and the story plot.
