Avengeformers

It didn't take long for the Avengers to come into contact with three Autobots, Optimus Prime, Bumblebee, and Ratchet. And it took even less time to realize they would be teamed up in an epic battle against the Decepticons and their new allies, the Slythers. Megatron has returned yet again, and has devised a single plan called Project Black Hole. In the sudden circumstances, the Avengers and Autobots create their team and call themselves the Avengeformers, all in order to save humanity from being sent into an alternate dimension within four days by finding three Black Hole Generators. With almost no information on the Generators, and no help from anyone at all, can they save Earth from the grasp of the Slythers and Decepticons? Join Optimus Prime, Tony Stark, Bumblebee, Natasha Romanoff, Clint Barton, Steve Rogers, Starscream, Nick Fury, Jetfire, Agent Coulson, Ratchet, Bruce Banner, and Thor Odinson on this epic journey of the multiverse where morals are challenged, loyalties are put to the limits, and a race against the clock makes even the strongest fall, and the weakest rise to take their place.

I do not own Transformers or Marvel or any of the characters from either two franchises that appear within the story.
