She was assigned to investigating illegal drug/narcotics trafficking routes into Japan. During her investigations, Karen uncovered that Crime controlled a majority of these routes and was going to assist ISSIS in destroying these routes. Crime attempted to kill Karen by arranging a fatal car accident. Miraculously, Karen survived the accident but lost her right arm. Her father, a fellow police officer, was also killed in the crash. Enraged and seeking revenge, Karen willingly accepted Joker's offer to undergo his bionic process and join JAKQ. Tvicon.png TV STORY-Ep. 1: 4 Cards!! The Trump is J.A.K.Q.

Heart Queen

Heart Queen

As Heart Queen, Karen's cybernetic enhancements enable her to control magnetic energy; which she dubs her “Heart Cute Jiki Power” (Heart Cute Magnet Power). Using her magnetic powers, Karen is able to push and pull metallic objects and was even able to halt bullets in flight. Her powers can be further enhanced by focusing them through her Heart Cute weapon; sending out waves of magnetic energy that can bowl over opponents or force them into erratic behaviors (which she gleefully enjoys and asks afterwards "Do you want another?" (もう一つ、いかがですか "Mō hitotsu, ikaga desu ka?").

Her Heart Cute weapon can be used as a blunt impact weapon or as a method to focus her magnetic powers. She is also equipped with a “Magnetic Counter” in her right index finger which can send out a magnetic detection pulse used to pinpoint and identify objects (both metal and organic) in a way similar to radar.

Ranger Key

The Heart Queen Ranger Key.

The Heart Queen Ranger Key (ハートクインレンジャーキー Hāto Kuin Renjā Kī) is Karen Mizuki's personal Ranger Key and what became of her powers after she along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The Heart Queen Ranger Key was mainly used by Ahim de Famille (Gokai Pink), who used it to fight as Heart Queen.

The J.A.K.Q. keys, along with all the Ranger Keys of the first 33 Super Sentai, were briefly taken by the Black Cross King and turned into Ranger puppets that were fought by the Gokaigers and the Goseigers. The J.A.K.Q. keys were defeated by Super Gosei Red. Tvicon.png TV STORY-Gokaiger Goseiger Super Sentai 199 Hero Great Battle

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Karen received her key and became Heart Queen once more. Tvicon.png TV STORY-Final Ep.: Farewell Space Pirates
