Kimberly Ann Hart/World of the Coinless

1="I’m gonna go kill Lord Drakkon. He’s taken Jason, Billy,... and now Matt. I’m not gonna let him take anyone else"

- Kimberly (World of the Coinless)

2="I'm bringing our lord back to us."

- Ranger Slayer to Finster 5 This version of Kimberly Ann Hart is from the World of the Coinless who (before being freed) had served under Lord Drakkon as a brainwashed Power Ranger, known as the Ranger Slayer. She is also the pilot of the Gravezord.

"The Fall of the Rangers"
The history of this version of Kimberly Hart parallels the history of her counterpart from the central timeline until events which creates the World of the Coinless. Kimberly fought alongside her fellow Power Rangers against the forces of Rita Repulsa and Lord Drakkon, culminating in "The Fall of the Power Rangers" battle that saw the deaths of Jason Lee Scott, Billy Cranston, and her world's version of Zordon. As a result of the battle, Lord Drakkon claimed the Tyrannosaurus, Sabertooth Tiger, Pterodactyl, and Mastodon Power Coins. Zack Taylor and Trini Kwan would eventually escape and form the resistance movement known as The Coinless.

Kimberly was also a member of the resistance helping get people to safety and running reconnaissance missions with Skull. On one of these missions, she witnesses the death of her universe's Matthew Cook. This, combined with the other losses she has experienced, leads her to wage an attack against Lord Drakkon on her own. While she is able to defeat many Sentries on her own, she is eventually possessed by Drakkon using a similar spell as the one Rita used on him as the Green Ranger. Even though the Pterodactyl Power Coin was originally claimed with the others and used to power Pterodactyl Sentries, the coin was returned to her and, combined with the new, evil energy of the Bow of Darkness, she is able to become the Ranger Slayer.

Shattered Grid
After Lord Drakkon's defeat during the Black Dragon arc of Mighty Morphin Power Rangers, he was dragged back into the present day by accident; eventually getting captured and remanded to the care of Promethea and its CEO (and Red Ranger of the 1969 Power Rangers) Grace Sterling. Meanwhile, on Drakkon's world, the power structures were under revolt as the Coinless were making strides and Scorpina and her loyalists were going rogue; a situation exacerbated by the arrival of the HyperForce Rangers. In desperation, Finster 5 gave the last shard of the Green Chaos Crystal to the Ranger Slayer with the hopes that she could use it and the Gravezord to track Lord Drakkon and bring him back.

Unfortunately for her, she arrived at a point when the Rangers were still new and long before Tommy Oliver ever arrived in Angel Grove. Desperate, she tried to contact Finster 5, but failed. It was then that Rita Repulsa arrived and offered to charge the Gravezord for her. Later the Ranger Slayer sent her Gravezord into downtown Angel Grove to draw out the Power Rangers, and while it attacked them, she suck into the Command Center with her Pterodactyl Power Coin. She used a Quantum Field Disruptor to disrupt Zordon’s brain, and ripped off Alpha 5's arm. She then issued an ultimatum: If they cooperate and let her use the Command Center’s sub-spectrum long-range communication array, she’ll leave them all in peace. When Alpha 5 got defiant, she readied to brutally attack him but then was attacked by the main world's Kimberly Hart, who ordered her to keep her hands off of Alpha. In the ensuing fight, the main world's Kimberly managed to shatter the Ranger Slayer's Bow of Darkness, and thus breaking Drakkon's hold on her.

Immediately, the elder Kimberly had PTSD flashbacks of what Drakkon made her do. To alleviate her pain, both Kimberlys went to the juice bar; where as Kimberly's cousin Sally, she was overjoyed to see Bulk (who was a loyal comrade in the World of the Coinless), and conflicted by seeing Matthew Cook (whose counterpart in her timeline died in her arms). Eventually, Drakkon managed to contact the Ranger Slayer saying that she would be stranded a little longer as he is on the verge of breaking the Morphin Grid. When he asked where her bow was, he realized that she had broken his control and left her to rot in the past.

She returned to the Command Center to repair her bow and plot her next move by using an opportunity changing the fate of past-present Power Rangers, including that timeline's Tommy and Matthew. She uses an improved Green Crystal to revive the Gravezord to fight alongside the Mighty Morphin Megazord against two monsters, then implanted one of the crystal's fragments into her arrows to shoot past-present Tommy, giving him the vision to prevent his original future-present's fate without killing him. The Rangers managed to defeat the two monsters with Mega Gravezord's Inferno Blaster.

Final Battle Against Lord Drakkon
Immediately after the battle with the two monsters, Kimberly was recruited to the main timeline by Grace Sterling, presumably bringing the Gravezord with her, as it unmerged and dematerialized from the Mighty Morphin Megazord at the same time.

She takes part in a rescue mission to Lord Drakkon's moonbase in the World of the Coinless as the other Rangers are waging the final battle against Drakkon's forces. Ultimately, the rescue is successful, and the depowered Rangers who were being held captive are taken aboard the Promethea.

She is aboard the ship as the World of the Coinless began tearing apart as space and time was wiped away. She observes as Andros tries to command the crew to teleport the Promethea base away and while the base manages to begin a teleport, it fades away into nothing as it does so. With no space or time to exist, once the multiverse was restarted, the Promethea re-materialized into existence and exited at a random vector from the teleport stream. While the Promethea has taken damage, she is seen, as the Ranger Slayer, helping to rescue the injured and trapped aboard the ship.

Beyond the Grid
After the events of Shattered Grid and the recreation of the multiverse, Kimberly is aboard the Promethea as it drifts through what seems like a void in space. She is one of the few Rangers who still has the ability to morph, though she observes that she has few morphs left in her morpher, since where the group is presumably has no access to a Morphing Grid.

She expresses a great amount of grief over her time as the possessed Ranger Slayer, and contemplates leaving the ship. However, she is stopped by Grace, who insists that she is needed and cannot leave.

She is the de facto leader of the new group of Power Rangers (consisting of herself, Tanya Sloan, Cameron Watanabe, Andros, Mike Corbett, and Heckyl). She leads them on a mission to answer a distress call that is heard somewhere in the universe, though it is revealed that the call was a ploy to lure her group away from the Promethea.

Personality
Kimberly remained the same as her prime counterpart, but her story became far more tragic upon losing her world’s Jason, Billy, and Matthew at the hands of Lord Drakkon. This leads her to decide to work alone for the sake of her friends. Due to being brainwashed with the evil energy in the Bow of Darkness implanted by Drakkon, Kimberly is turned as ruthless as Drakkon. However, the only known remaining good side left in her is sparing the past-present counterpart of Matthew, to make sure he will never die as his World of the Coinless counterpart did.

After her past-present-day counterpart manages to unleash an energy blast that breaks the Bow of Darkness and clears her of her connection to Drakkon's magic and manipulations, she is left shaken and furious at herself for what she did under his influence. She is not truly the monster she was made to be, feeling an immense sense of personal accountability for the things that she was forced to do under the mad ranger's control.

Due to her world's ruined state, she has come to appreciate the small things in life. While spending time with her pst-present-day counterpart, Kimberly took time to remind her younger self to take time to appreciate life's small trivial pleasures, such as days at her favorite hangouts, the goofiness of her friends, and even high school, as such small things is what the larger battles are fought to protect: the chance to live one's life and not have to fight for it.

Due to having been controlled and manipulated by Drakkon for so long and having lost so many people including Jason, Billy, Matt, and many others, Kimberly defected, explicitly stating her intent to kill Drakkon herself. Due to the subtle undertones of Drakkon's conversation with her prior to the revelation that she is free from him, it is implied that Kimberly was made to be in a relationship with him against her will. Given the depths of Drakkon's madness and depravity, it is quite likely that Kimberly was coerced by him in such a manner.

Behind the Scenes

 * Kyle Higgins described the Ranger as someone we have seen before, but not in this way. The clue to her identity as Kimberly was actually set up and somewhat foreshadowed early in the comics during the Black Dragon Arc.
 * Four out of five Rangers of the Mighty Morphin team were either dead or de-powered in the World of the Coinless as seen in the story: Jason and Billy were murdered by Lord Drakkon when he first got his fused powers, Zack and Trini had lost their Power Coins to Lord Drakkon but managed to survive as part of the resistance.
 * Up until the reveal at WonderCon 2018's Boom! Studios panel, readers assumed the Kimberly of the World of the Coinless was killed by Lord Drakkon due to the fact that the Ranger Sentries need the energy of specific Power Coins to be able to morph and her coin's powers were being used by the Pterodactyl Sentries. Adding to this ruse was the fact that Kimberly was never seen, except in flashbacks during "The Fall of the Power Rangers".
