<b>Nabiki</b> is the middle of the three Tendo sisters, and a senior at Furinkan High School. She has done several things to obtain money, such as selling clandestinely-taken photos of <b>Ranma</b> and <b>Akane</b>, making book on <b>Ranma</b>'s fights, and blackmail.

She also was willing to let someone fall to his death rather than lose a bet—quite literally, although the man did survive a very long drop from a helicopter. She also has a small group of flunkies who will assist her when the need arises.

Despite the fact that she comes from a martial arts school, <b>Nabiki</b> is not a combatant. Although she always keeps her wits about her, she is unable to fight. The only fighting skill she has shown is the ability to use a variation of her father's Yokai head technique when she is very upset with him; examples of this are: when <b>Soun</b> lost the Dojo in a bet and when she discovered her father had sold her into a marriage to the Chardin family.
