The TAV-21 Optimus Prime marks the first in a larger class size for the Transformers Adventures line. He stands 11.80" tall in robot mode and features light and sound electronics. He transforms into a futuristic trailer truck and the trailer can also be converted into a battle station. When you scan the Autobot symbol on his left shoulder with the TakaraTomy version of the Robots in Disguise mobile app you unlock the toy in the collection list.
Transformers Adventure is the Japanese version of the Robots in Disguise franchise launched in 2015 that focuses on Bumblebee and a group of Autobots that travel to Earth to capture Decepticon criminals. The faction symbol “shields” on each figure can be scanned with the compatible app to temporarily unlock the toy for use in the game.
