Transformers: Robots in Disguise-1
Following in the storyline of Transformers Prime, when a new age of peace is ushered in on Cybertron, many heroes of the past war chose humble service. Bumblebee, upon seeing a vision of Optimus Prime, leads a small team of Autobots to Earth to counter a new Decepticon Threat -- escapees from the prison ship Alchemor, crash landed in the scrapyard belonging to Denny Clay. Allied with the 'junk collector' and his son, Russel, Bumblebee, Strongarm, Sideswipe and Grimlock -- with the Alchemor's resident caretaker and minibot Fixit, seek to keep their cover in disguise and not alert Earth to their presence while capturing escaped Decepticons and restoring them to cryopods for continued imprisonment.
Little do they know how much danger they could be in, as the rag-tag group builds up their strength -- and trust -- in their teammates and themselves, Decepticons regroup, and ready themselves to fight.
