Karen Mizuki

"Heart Queen!"

- Heart Queen's roll call

Karen Mizuki (カレン水木) is Heart Queen (ハートクイン) of J.A.K.Q. She is half Japanese/half Caucasian and a former policewoman.

J.A.K.Q.
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.

Gaoranger vs. Super Sentai
Heart Queen is among the Sentai warriors seen in clips when Miku Imamura (MegaPink) lectured Sae Taiga (GaoWhite) about the past female Super Sentai warriors and their shared mastery of disguise and habit of changing their clothing in the blink of an eye, something that Sae had never done before.

Legend War
Years later, Karen fought alongside not only her own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders. Akarenger noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. The Heart Queen powers are later utilized by Ahim de Famille via the Ranger Keys.

Farewell Space Pirates
After the Zangyack's final defeat, Marvelous returned the Ranger Keys to their original owners. It is assumed Karen and her teammates have their powers once again.

Super Hero Taisen
Karen, alongside her team, among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker. During the final battle, she was seen in the background fighting Yaiba of Darkness.

Personality
Karen is a skilled martial artist and is proficient in a number of fighting methods. For a time she was part of the Kono Karate School where she befriended Kono Natsuko (Shihomi Etsuko) who was also a skilled martial artist. Karen has a flair for fashion and often sported tight red leather ‘hot pants’ and red long boots. Towards the end of the series, she fell in love with teammate Goro Sakurai (Spade Ace).

Super Sentai Battle: Dice-O

 * Profile:
 * Karen Mizuki/Heart Queen: J.A.K.Q.'s lone woman, who fights Crime to avenge her father's enemy. With specialties in disguises and karate, she defeats enemies after transformation with her Q-shaped magnetic shield: the Heart Cute

Super Sentai Battle Base
Heart Queen is among the vast pantheon of Rangers which are avaliable in the mobile game Super Sentai Battle Base.

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).

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
"J.A.K.Q.!"

- Mobilates' Gokai Change announcement

The Heart Queen Ranger Key (ハートクインレンジャーキー) 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.
 * Alongside Marvelous, Joe, and Don, as they became the original four Jackers while fighting Action Commander Nanonanoda.
 * When the Gokaigers became JAKQ in their fight against Action Commander Zaggai.
 * When the Gokaigers became JAKQ in order to use the Big Bomber cannon against Action Commander Shieldon in a vain attempt to penetrate his shield.

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.

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.
