The Kingdom Hearts series is chock-full of relatable and endearing characters, each of whom serves a crucial role in the overarching story. With each entry comes an array of new characters to further enhance the plot, but it's hard to ignore the emphasis placed on introducing male characters over females.

Though the female cast list of Kingdom Hearts is a short one, it is pointless to ignore how vital the few who appear are. Whether their intentions are pure or ill-willed, the series has made it clear that it knows how to write compelling women into its stories when it eventually decides to introduce them.

10 Invi

Invi is arguably the most calculated Foreteller to exist during the Age of Fairytales, but her devotion to the Master of Masters often clouds her judgment. Her role in Kingdom Hearts: Back Cover is to monitor her peers and ensure they fulfill the Master's wishes.

She is honorable to a fault, evident through her willingness to attack those she believes are swaying from their given paths. The epilogue of Kingdom Hearts 3 revealed that her fate has yet to be decided, giving her a second chance to rectify her mistakes.

9 Urd

Urd makes her first appearance in Kingdom Hearts: Dark Road and, though she quickly became a fan favorite, her future in the series is unclear. Before Xehanort became his twisted self, he studied to become a Keyblade Master at Scala ad Caelum alongside his childhood friends. Though he regarded Eraqus as his dearest companion, Urd wasn't far behind.

Urd is surprisingly powerful for a lowerclassman, but she's not invincible. She refuses to shy away from battles no matter the danger and usually comes out on top. She meets her end while wandering a Dark Corridor and is buried at Scala shortly after. It's likely her story has ended, but anything is possible in Kingdom Hearts.

8 Ava

Not much is known about Ava's past, and her future is even less clear, but she is undoubtedly one of the best characters in Kingdom Hearts: Back Cover. If not for her quick thinking and willingness to blindly follow orders, the Dandelions would never have survived the Keyblade War.

Her absence during Kingdom Hearts 3's epilogue suggests that she will no longer be following the Master's commands. If so, she will be the first Foreteller to reject his teachings and try to stand on her own two feet. She will likely be returning to the story as a hero, but nothing is ever certain with Tetsuya Nomura's method of storytelling.

7 Skuld

Though Skuld has yet to make an appearance in a mainline Kingdom Hearts entry, her time in Union X [Cross] has cemented her as one of the best characters in the series. Alongside Ephemer, she acts as one of the player's closest friends and tries to aid them as best she can in a crumbling world.

Skuld's fate has yet to be confirmed, but many are convinced the "Subject X" mentioned in the Secret Reports of Kingdom Hearts 3 is referring to her. If this is true, it seems Xigbar discovered Skuld in the dungeons of Hollow Bastion and has been hiding her ever since. Though she was introduced as a hero, there is a chance that Xigbar's manipulations will transform her into a villain.

6 Strelitzia

Strelitzia first appears in Kingdom Hearts: Union X [Cross], but her time is short-lived. Even so, she quickly became a fan favorite due to how melancholy her story was. Fans were devastated when she died, but the trailer for Kingdom Hearts 4 revealed her death to be less permanent than it seemed.

Strelitzia harbors vast knowledge of the ancient Keyblade War and, like Sora, is the only known character to have accidentally found themselves in Quadratum's fictional world. It is rare for Kingdom Hearts characters to die, making her one of the most interesting exceptions to appear so far.

5 Naminé

Naminé's introduction to the Kingdom Hearts series aims to portray her as a villain. She appears to be working alongside Organization 13 to distort Sora's memories and corrupt his heart, but not once does she perform these actions with malicious intent. She, like Sora, is a prisoner in Castle Oblivion and must abide by Marluxia's command if she hopes to survive.

As if her time in Chain of Memories wasn't sad enough, Naminé only gets the chance to live a happy life after the events of Kingdom Hearts 3. She faded into Kairi's heart during Kingdom Hearts 2 and was forced to stay there until a replica was made available for her to occupy. Naminé has undergone some serious suffering throughout the series, but it seems she will finally be rewarded for her patience in future installments.

4 Larxene

Larxene made her first appearance in Kingdom Hearts: Chain of Memories where she solidified herself as one of the most ruthless villains in the series. Most Kingdom Hearts antagonists are oozing with pure evil, but not many take pride in the suffering they cause. Larxene, however, is a frightening exception. When she's not gaslighting Sora and his friends, she will likely be seen planning to betray her comrades purely for the fun of it.

She is undoubtedly the cruelest member of Organization 13 thanks to her condescending tone and the actor who plays her. If not for the voice acting talents of Shanelle Workman Gray, Larxene would be a far less intimidating presence. Before joining the Organization, Larxene went by the name Elrena. She was a Keyblade wielder who resided in Daybreak Town long ago before being transported to the future. Her unlikely past suggests her future will be full of surprises.

3 Kairi

Kairi began her story as a strong and determined young woman who wanted nothing more than to join Sora and Riku on their adventures. She had great potential, but her character was somewhat undermined during the events of Kingdom Hearts 3. Thankfully, the Re Mind DLC chose to remedy her prior failures by making her a playable character and pitting her up against the main antagonist of the series.

Her moment in the spotlight presented her as a bafflingly powerful ally, capable of combating the franchise's greatest threats. If not for her help during the final confrontation, Sora may not have been able to defeat Xehanort, further proving how powerful she is. The climax of Melody of Memory sees her asking Yen Sid if she can be trained under Aqua. With Aqua's help, she is likely to regain the reputable status she held in Kingdom Hearts 2 and thus become an even better character.

2 Xion

Xion makes her debut in Kingdom Hearts in 358/2 Days when she becomes the fourteenth member of the unfortunately named Organization 13. She is presented as an enigma at first, but slowly opens up thanks to Roxas's approachable nature. She is eventually revealed to be a Keyblade wielder, making her one of the most powerful members of the Organization.

Upon discovering her reason for being, Xion decides to sacrifice herself so Sora can regain his memories. She is perhaps the noblest character in the series because of her willingness to help others. If her heart-wrenching story arc isn't enough to convince fans of how great she is, her theme Musique Pour la Tristesse de Xion most certainly is.

1 Aqua

Aqua is without a doubt the most powerful female Keyblade wielder in all of Kingdom Hearts. She is introduced to the story in Birth By Sleep where she spares no time in showcasing her strength. She is dubbed a "Keyblade Master" within the first hour of gameplay and spends the rest of the narrative proving herself to be worthy of the title.

As well as being one of the most powerful characters in the series, she has also experienced the most trauma out of all her peers. She becomes trapped in the realm of Darkness while trying to protect Terra and is forced to wander the abyss for ten years. Sora eventually rescues her and, though her time away from the Realm of Light took a toll, she remains a force to be reckoned with.
