What if the 13 Primes were alive to this day? Alive AU

It seems Unicron hasn't been defeated as he was now hiding inside Earth. So the Primes grabbed a space shuttle and took off from Cybertron. It was going to be a very long journey....trying to avoid Quintesson ships, cosmic rust on isolated planets, and dark energon matter floating around in space. As much as they would have loved to stay on Cybertron...they couldn't have Unicron torment yet another planet filled with fragile creatures..
