Under the command of the fearless OPTIMUS PRIME®, AUTOBOT RATCHET and AUTOBOT JAZZ left their ancient home of CYBERTRON™ to wander the infinite breadth of deep space in search of the AllSpark. Hoping against hope, they searched, dreaming of the day they would return home bearing life and light. They found little of their quarry among the stars, but they carried with them always hope and healing for the sentient creatures they encountered. The search for the AllSpark has now ended, but the battle rages on. From one world to the next, they battle and defeat the DECEPTICONS®, leaving freedom in their wake. For ages BLACKOUT and BARRICADE have raged across the galaxy alongside MEGATRON®, bringing sorrow and destruction wherever they stepped. Hundreds of worlds bear the deep scars left by their heavy feet, cities and mountains cut to pieces by the heat of their lasers. They have quested in search of the AllSpark, that legendary artifact that will, at long last, make them invincible. Though deprived of their leader MEGATRON®, their quest continues, and at its end lie the broken, rusting bodies of their eternal enemies – the AUTOBOTS®.
