It's The Marvel Universe Variant Play Arts Kai Figures - Black Widow.
Black Widow is a world-class spy who stands out within the Marvel Universe. Clad in her signature form-fitting black body suit for this Variant series, Square Enix paid close attention to both her feminine physique and the design of her protective armor to ensure it allowed a wide range of mobility. The paintwork and the color balance are exquisite, with varying contrasts on different parts and metallic paint application, which make for great accents that add flare to her look.
Her accessories include special effect parts to replicate the electric shock of the stun barrettes and shots being fired out of her guns, and various gadgets including two handguns, and a knife, making this a substantial package.
Figure includes display stand.
