First Strike (IDW 2005)

The Transformers are a massively powerful, ancient alien race that has been warring with itself for millions of years. That war has brought death and destruction to every planet it has touched. And now, The Transformers have annexed earth into their galactic empire. History tells us this could be a problem. What, if anything, can one person do to save a planet? What sacrifices must be made to save mankind? ...How do you destroy all The Transformers?

A Hasbro comic book event! A new era of peace is dawning as Earth formally joins the Cybertronian Council of Worlds. That is… until Baron Ironblood joins Destro, Storm Shadow and other nefarious villains in a terrorist attack on Iacon! As chaos takes hold on Cybertron, it will be left to Scarlett and the rest of G.I. Joe on Earth to discover the true purpose behind the attack before both worlds descend into all-out-war!

With Cybertron under siege by Baron Ironblood's forces, Optimus Prime and Arcee defend their homeland! Caught in the middle is the human/Transformer team known as the Revolutionaries—and one of them has a secret that puts everyone at risk!

The crossover of the year continues! Scarlett learns the truth behind Baron Ironblood's plan to destroy all life on Cybertron, but with her team stranded on Earth, she must turn to an unlikely ally to help her reach the besieged planet. Enter: Soundwave!

Secrets revealed! G.I. Joe, the Autobots and M.A.S.K. make their way to Cybertron to stop the siege and encounter the COBRA leader, but all is not as it seems! Will their arrival help—or just bring more disaster?

Captured by Transformers! Even with the Autobots on their side, G.I. Joe is in trouble! Starscream doesn't trust anyone, much less armed humans who show up during Cybertron's darkest hour and he'll do anything he can to keep G.I. Joe under control—including let COBRA get even closer to their goal!

Continued from Optimus Prime: First Strike! When a bounty hunter drags one of their own into the wilds of Cybertron, the Revolutionaries join forces with Arcee and pursue! But in the midst of war, can humans and Cybertronians put aside their differences, or has the invasion of Cybertron doomed any chance at peace?

Prison Break! After a daring escape, Optimus Prime, the Autobots, Scarlett, G.I. Joe and M.A.S.K. must venture into the heart of Cybertron to stop Cobra's devastating weapon that will kill every Transformer on the planet!

War for the Core! Deep within Cybertron, the ultimate weapon to kill all Transformers is about to be activated! Meanwhile, Elita One plans to stop the weapon—by killing every human on Cybertron! Either way, looks like some species on Cybertron is going down unless Optimus Prime and Scarlett can save the day…
