The Celebrity Doll Museum also has the white Mattel Platinum version in the collection.
From the box:
Barbie® captures the attitude of the Black Widow aka Natasha Romanoff. Armed with dual batons her electric Widow Bite gauntlets, Black Widow combines acrobatics with her expertise in various martial arts – including karate, kung fu, and judo – to accomplish her mission. Marvel’s Black Widow Barbie® doll reflects the unwavering bravery and unstoppable determination she uses in the fight to protect the world.
The Scarlett Johansson doll comes wearing a black collared bodysuit with gray markings with shiny black and red plastic shoulder pads, gold and black wrist gauntlet launchers, a black plastic backpack to hold the batons, a black plastic with gold and red painted buckle combination belt/thigh pistol holster.
On the feet are black plastic knee-high boots which are capable of balancing the doll to stand on its own. They have slits up the back for easy removal and to reveal the normal Barbie high heel feet. The hands are painted with black finger-less gloves and the fingers are curved to hold the black plastic batons. The two black plastic pistols are part of the holster which unfortunately cannot be separated from the holster. All the clothing is removable. The bodysuit would require serious stretching to remove the body through the neck opening.
The face has realistic pixelated painted green eyes, reddish painted eyebrows, and pink lips. On the doll’s left earlobe, there are three silver painted small hoop earrings. The waist length pony tailed red rooted hair is soft and comb-able with three red braid coming down from the doll pony tail holder band. The braid ends are secured with a small rubber bands.
The doll has the new Mattel female superhero body which is articulated at the neck (twists and small up and down motion), shoulders and hips(ball joints), knees, elbows, and wrists. The torso/waist and the ankles are fixed. The doll can do both the side and front and back splits and the knees go up to 90 degrees before they swing wide. The doll can be posed in most martial arts poses that don’t require kicks higher that 90 degrees or any twist in the torso. The suit and holster are designed to move with the poses. The batons poly-banded into the hands but they are removable and fit in the back pack.
An unnumbered Mattel Certificate of Authenticity and clear plastic stand with a black base are also included.
