TRANSFORMERS TIMELINES (2011)

"Optimus Prime versus Megatron. A bitter rivalry that has spanned decades, generations, and now even universes! In this all-new story set in the multiversal hub known as Axiom Nexus, the heroic Autobot General Optimus Prime is on the hunt for his nefarious Decepticon counterpart and the rest of Cybertron's Most Wanted after what would appear to a brilliant prison break. However, in the Cybertronian city of Axiom Nexus, nothing is ever what it seems; the power outage that allowed the breakout was actually caused by something far more dangerous. Something lurking in the shadows, deep inside the caverns city."

"Noble, wise, and loyal to the cause, the Knights of Cybertron are steadfast in their protection of their homeworld. Any villainy that dare threaten the planet will be met with valiant courage, unwavering will, and Cybertron's greatest warriors! What remains of Unicron has cast its shadow over Cybertron for years, a constant reminder to the planet's inhabitants of the war that almost destroyed their world. Though he has been dormant for a long time, Captain Cannonball, Scorponok, and the pirate crew of the Star Seekers have arrived to change that. Hoping to use Unicron's insatiable hunger to drain Cybertron of Energon, the pirates may have underestimated the chaosbringer's own ambitions!"
