This is a posable action figure from the Revoltech series.
Kaiyodo unleashes their first mass-market deluxe box set in their hit Revoltech toy line: Sousuke's tremendously powerful Arm Slave ARX-8 Laevatein, with a slew of armaments and attachments befitting the one-man army mecha! The 12.5cm Revoltech action figure utilizes 16 Revolver joints and boasts 50 points of articulation for a world of posing possibilities! Its weapons and accessories include a 165mm demolition gun with Gun-Howitzer Mode attachment, two demolition gun magazines, a 76mm shot canon, a pair of anti-tank daggers, two AS-grenades, a pair of monomolecular cutters, a pair of stored monomolecular cutters, two shoulder armor parts, two Lamda Driver Cancelers, three robot arms, five optional hands, an interchangeable head, and a heat-dispensing wire part. A display base with joint arm is included to assist with dynamic poses. Please note that figures such as this are mass produced and as a result some inconsistencies in finish and painting may occur; these are not considered manufacturer's defects. If you absolutely must have perfection, prepare to do some touch-up work on your own.
