About LEGO Shadow's Mech vs. G.U.N. Trooper

Gaming enthusiasts and LEGO builders aged 8 and above will find plenty of action in this 374-piece Sonic the Hedgehog battle set. The centrepiece is Shadow's imposing mech, which stands over 20 cm high, 16 cm wide and 14 cm deep, equipped with articulated limbs and four shoulder-mounted stud shooters for dynamic combat scenarios.

The mech features opening bull bars at the front that deploy the included Dark Rider motorcycle, adding tactical variety to play. Shadow can also equip a pair of Doom Wings for aerial manoeuvres, while the mech itself comes armed with two swords for close-quarters combat.

Figures and Accessories

The set includes a Shadow the Hedgehog minifigure and a G.U.N. Trooper figure, setting up the classic hero-versus-military conflict from the video game series. Two collectible Chaos Emeralds are included, adding authentic details from the Sonic universe.

Build Features

All limbs on the mech are fully posable, allowing builders to create dynamic action poses and battle stances. The motorcycle can be stored within the mech or deployed separately, whilst the shoulder-mounted weapons provide multiple points of articulation for targeting enemies during imaginative play scenarios.
