Now, Sunny Starscout and her friends must team-up with the Autobots and rekindle the relationship between Equestria and Cybertron.

This is my first MLP G5 and Transformers story
This story will be a continuation of the IDW My Little Pony G4/Transformers comic crossovers, Friendship in Disguise and The Magic of Cybertron.
This just my idea of what a possible third sequel to the IDW My Little Pony G4/Transformers comic crossovers would be like, if the sequel was set in the world of MLP G5.
