6. Gogo Yubari - Kill Bill Vol. 1
She dresses like a Japanese schoolgirl, looks barely old enough to drive and her name derives from Mach GoGoGo (Speed Racer), but you underestimate the bodyguard of O-Ren Ishii (Lucy Liu) at your peril, as one character discovers in an early scene. When a businessman attempts to pick her up in a bar, Gogo stabs him with a samurai sword and says, Do you still wish to penetrate me? Or is it I who has penetrated you? But her biggest moment comes in her showdown with The Bride, where her love of weaponry becomes apparent. Armed with nothing less than a meteor hammer, she takes a characteristically sadistic delight in attempting to strangle her nemesis with the chain, only for her efforts to be curtailed by a nail to the brain. Incidentally, if the character looks familiar, thats because Tarantino based Chiaki Kuriyamas part on her role in Battle Royale.
