In the Battle of Chicago scene from Transformers: Dark of the Moon, Sentinel Prime squares off against Optimus Prime in a fight to save their homeland of Cybertron, but at great cost. For Cybertron to survive, it must enter Earth’s atmosphere through a space bridge and drain it of its natural resources. Seeing victory slip away, Sentinel Prime calls for reinforcement from nearby Decepticon ships to delay Optimus Prime long enough for the space bridge to be opened. This Studio Series 61 Voyager Class Transformers: Dark of the Moon-inspired Sentinel Prime figure converts from robot to Rosenbauer fire engine mode in 32 steps. Remove backdrop to showcase Sentinel Prime in the Battle of Chicago scene. Figure features vivid, movie-inspired deco.
