MP-21G Masterpiece Bumblebee has a metallic gold G2 paint job and transforms into an officially-licensed Volkswagen Type 1 Beetle. He comes with three swappable face plates including the smiling mask, neutral mask, and battle mask; two side mirrors, spare tire cover, license plate, and a pistol. This version includes a jet-pack as worn by Bumblebee in the cartoon episode "Dinobot Island, Part 1" instead of the Exosuit figure. In robot mode, he is in scale with MP-10 Optimus Prime's robot mode, making him out of proportion with the other Masterpiece cars. In car mode, he can fit inside MP-10 Optimus Prime's trailer.
Cited as the stealthiest and most energy efficient of the Autobots, configured for underwater reconnaissance, Bumblebee is especially proficient in his capacity as spy. Among the most loyal and courageous of Optimus Prime’s original crew of Autobots, Bumblebee quickly becomes a surrogate big brother to Spike Witwicky; Bumblebee is subsequently present alongside the adult Spike when Unicron’s monstrous planet mode unexpectedly attacks Moonbase 2.
