Karateka/Headscratchers


 * If Mariko can kill the hero in one hit, why can't she just escape herself?
 * Because she doesn't kill the hero due to her overwhelming martial arts ability, she kills the hero because he doesn't expect the attack - the same reason any enemy can One Hit Kill the hero if he's not in fighting stance. Presumably her guards would be much less trusting.
 * Also, the hero is short enough such that Mariko could kick him in his One Hit Kill spot, whereas the Big Bad is too tall for that to work.
