Set adapted by Arturo and tested by Peter Durieux.
Protect the Chaos Emerald or hunt for more with Shadow’s Mech vs. GUN Trooper (77120), an action-packed building toy for boys and girls ages 8 and up. Kids can create fierce battles between Shadow the Hedgehog and the GUN Trooper with the mech and Dark Rider motorcycle. Control the mech action figure’s articulated limbs, 2 swords and 4 shoulder-mounted stud shooters. Kids can help Shadow hop on the motorcycle or attach the Doom Wings to the mech or Shadow for more imaginative role play possibilities. This pretend-play toy makes a cool gamer gift for boys, girls and video game merch collectors. Expand the play and display possibilities with other LEGO® Sonic the Hedgehog™ toys, sold separately.
The packaging captures the speed and intensity of a battle from the Sonic the Hedgehog universe, with Shadow, his powerful mech, the Dark Rider motorcycle, and the GUN Trooper arranged across a dramatic outdoor scene. The front of the box shows Shadow’s large mech charging into battle, its black, red, and white armor highlighted by pearl-gold details, broad white feet, pointed shoulder sections, and dark wings extending from its back. The mech is posed with its articulated arms and legs spread dynamically, holding a long pearl-gold sword in each hand, while the four shoulder-mounted stud shooters point toward the action. The smaller dark green, black, and dark orange GUN Trooper stands nearby with its compact limbs bent into a fighting stance and its projectile launcher raised. Shadow rides the black and red Dark Rider motorcycle through the center of the scene, with the vehicle angled forward as though racing between the two machines. The background resembles a rugged Sonic landscape, with rocky ground, distant mountains, clouds, and a dark blue sky framing the confrontation. On the top left corner, we have the classic LEGO logo, followed by the Sonic the Hedgehog branding. Along the left side, the set information is also visible, including the age rating, set number, name, and piece count. The left of the box continues the LEGO Sonic the Hedgehog visual style, with an image of Shadow. The back of the box shows another arrangement of the included characters and builds, now focusing more clearly on the set’s play features. Namely, smaller images show that the mech has articulated arms and legs for different battle poses, can hold both pearl-gold swords, and includes four shoulder-mounted stud shooters that can fire their transparent dark pink ammunition. It also shows how the bull bars on the front of the mech can open, allowing the Dark Rider motorcycle to be stored in or deployed from the torso area. The GUN Trooper is shown in an opposing pose with its movable limbs and projectile launcher, while the two Chaos Emeralds provide objectives for the battle. On the top left corner, we have the LEGO logo, together with the Sonic the Hedgehog branding. The right side of the box contains multilingual product and safety information, including the warning that the set contains small parts and is therefore not suitable for children younger than 3 years old. The top of the box has the classic LEGO logo, the Sonic the Hedgehog branding, the name and number of the set, and a 1:1 scale image of Shadow. The bottom of the box is a tidy strip that contains the barcode as well as a few technical bits: the LEGO logo, SEGA and Sonic the Hedgehog copyright and trademark information, the set number, recycling information, manufacturing details, and other packaging notices.
