Transformers:Aftermath is a series that takes place 4 years after the live-action movie, in the year 2011. Mini-Cons exist in this universe. The human's attitude towards Transformers is largely cautionary, as evidenced by the development of the Anti-Transformer-Robots, or ATRs. Some groups, like Black Sunshine, are more violent in their methods.
When evidence surfaces that the All Spark is back, Optimus and Starscream send a team each to Earth, with the intention of finding the All Spark. The main problem is that the All Spark's energy had been dispersed, and is now starting to gather back together. The two sides realize the potential danger of too much energy in one place, and must get it before something catastrophic occurs.
