Meet the World’s First Auto Converting Flagship Optimus Prime TRAILER KIT by Robosen

Backup has arrived and is here to fully equip your FLAGSHIP Optimus Prime with the addition of the World’s First auto- converting Trailer and Roller set! Expand your arsenal and defend against the Decepticons by completing the ultimate, auto-converting, Optimus Prime experience ever to launch! Modeled after the original G1 design, and measuring at an impressive 3ft (91mm) in height (when fully extended with combat deck grapple-arm), the Trailer auto-converts into maintenance and battle mode by folding open, pivoting upwards, and exposing its massive firepower from within the combat deck. Stationed inside, Roller awaits your command to explore and engage the enemy, all via app control - along with human sidekick Spike, who is ready to jump into action or enjoy the ride!
