AKA Black Mamba This here? This is a trained assassin, Beatrix Kiddo, code name: Black Mamba. She's here for revenge. She's here to kill Bill. And although a long trail of gore follows in her wake, we kind of admire Ms. Kiddo. She never took no for an answer. She's stubborn to a fault, making sure she finishes her business. Not to mention her serious skills. She definitely operates under anti-hero territory. Fun Details Now, you can look that part of the Quentin Tarantino anti-hero with this Kill Bill Beatrix Kiddo Costumed, AKA The Black Mamba. It's a simple yellow polyester tracksuit with black stripes down the sides . The jacket has a front zipper and high collar, and the pants have bell-bottom style legs. You'll look just like Beatrix when she took on Go Go, O-Ren, and the Crazy 88. That is, exactly like her, minus bloodstains. But we're pretty sure this costume looks better without them.
