Organization XIII are a reoccurring group of villains inthe Kingdom Hearts series. They initially appeared in Chain of Memories before being the main antagonists in 2. At that point in time, there were 13 members total, but more recent games have made the total count rise to 20.

This list will rank every Organization XIII member in the entire series based on how important they are, their writing quality, and how unique their fights are.
20Lexaelus
Many Organization members don’t have much backstory in the first game they appear in, but they usually get more lore in follow-up entries. That has yet to happen for Lexaelus, and the chances of fans learning more about the characters grows less likely as the series goes on.
Lexaelus is also very forgettable due to having very little screen time. His largest appearance is within Riku’s Chain of Memories story, and even then he is one of the least relevant villains. Additionally, his weapon is relatively basic compared to what other Organization members use.

Xaldin is another unimportant member of the Organization, but he is a little more memorable than Lexaelus. He appears fairly early inKingdom Hearts 2’s main storyline. Xaldin acts as the final boss within the third world, the Beast’s Castle.
He fights with six axes that he can control from a distance. Like Lexaelus, the chances of Xaldin becoming a more interesting character have dwindled since the Dark Seeker Saga came to its conclusion inKingdom Hearts 3.

Vexen is the highest ranking Organization member seen in Chain of Memories, but he isn’t considered the main antagonist of the game. Still, he does play a slightly important role. Vexen’s boss fight near the end of the game is one of the hardest in the main storyline, and he is the person who created Riku’s replica.

Most Organization members in Chain of Memories want to betray the Organization, but Vexen remains loyal until Kingdom Hearts 3. His growth is mildly interesting, but it happens almost entirely in the background.
The previous members on this list were exclusive to the Organization XIII seen in Chain of Memories and 2, but Luxord also reappears as a member of the True Organization XIII introduced inDream Drop Distance.

He’s even mildly relevant for a world in Kingdom Hearts 3. Luxord fights using playing cards that can inflict unique status effects. He feels much more unique than some other members due to his fight being somewhat like a mini-game.
Out of all the Organization members introduced in Chain of Memories, Larxene is the one with the most screen time. She isn’t the final boss, nor does she leave a large impact on the story, but her cold personality is very memorable.

Larxene fights using eight throwing knives. She doesn’t reappear in follow-up main installments, but the mobile game Kingdom Hearts X [Chi] reveals her human counterpart originally came from an ancient era.
Dance, water, dance! Both Demyx’s weapon and personality make him a stand-out member of the Organization despite having very little story significance.

Demyx is very chill, which makes him quite different from the often stone-cold brutes that make up the Organization. He fights using a guitar that can create many water replicas of itself.
Saix is another member that appears in both incarnations of Organization XIII. What makes him stand out from the others is his unique dynamic with another member. He and Axel were best friends when they were still human inBirth By Sleep.
Saix currently has the most potential to gain improved writing. He has a chance to have a redemption arc in future installments now that the Organization is defeated and since he has rejoined Axel by the end of Kingdom Hearts 3.
13Young Xehanort
Xehanort may be the main antagonists of the entire series, but his young counterpart comes from a time when he has yet to commit most of his foul acts. He is rarely shown outside the Dark Road mobile game.

Despite being the same person, young Xehanort doesn’t have the same experience, iconic moments, or impact that his older counterpart has. This counterpart is still a good character, but he doesn’t quite live up to the present Xehanort’s impact.
12Marluxia
Marluxia acts as the final boss for the second Kingdom Hearts game, Chain of Memories. Most final bosses in the series are in some way Xehanort, so this makes Marluxia stand out a lot.
Marluxia hasn’t returned to the canon storyline since his defeat, but his standout presence, design, and boss fight make him a very memorable part of the Organization.
Xion was first introduced in the DS title 358/2 Days, in which she is very significant. She acts as a potential replacement for Roxas if Xehanort deems him unusable. This makes her the secondary protagonist of the game.
Her death at the end is one of the most tragic moments in the entire series. Xion was eventually brought back in Kingdom Hearts 3 after fan demand to see her again grew, but her relevance in that game is vastly smaller.
