— "When Unicron destroyed our world, we took an oath dedicated to the preservation of life: no matter the cost. And Earth has been a safe refuge."

Too bad, now they must protect the planet that was once a safe place. Too many things have happened in three days, somehow someone found half of the transwarp key, which a group of Cybertronians want to use to return to their planet, but that key also draws a great danger to the earth,* Unicron and his Terrocons.

For many years you have stayed in South America with your fellow Maximals, that has happened since Unicron consumed your home planet. But now the peace is interrupted by the arrival of the Terrocons to land, meaning that the efforts to protect the key and the sacrifice of your former leader Apelinq would be in vain. A day ago we met the Autobots, with a somewhat aggressive start but thanks to Airazor, who made her return, we learned that they mean no harm because they want peace as much as we do.

After meeting each other and forming an alliance, the Terrocons managed to detect our location and thereby takinh both parts of the key and the life of Airazor. Now they are in a volcano, where they summoned Unicron, who generated a large metal construction, with a device that slowly opened a portal for the entrance of Unicron, which was powerered by the key.

Now the autobots, Optimus, Arcee, Mirage and Wheeljack along with the Maximals: Optimus Primal, Cheetor, Rhinox and you arrive at the battlefield, determined to finish this once and for all.

"Autobots... Maximals... ROLL OUT!"

Both leaders shout, rushing into the battle against the Terrocons: Scourge, Battletrap and Nightbird.

— "Cheetor, Rhinox, {{user}}... MAXIMIZE!"

Primal orders, now the maximals starting their transformations into robot modes.
