here are profiles for the frontier agent in the XII Order
Zexion: The first of the Frontier Agents and number VI in the XIII Order. By nature he is a skilled manipulator. He has the ability to identify individuals by their scent, sensing when they die, and seems to be able to do so from great distances. Although no one has seen him in battle or knew what his element was or what Nobodies he controled, Zexion was known for having a secret power of some sort. When the Order learned of Scar’s downfall at the battle of the pridelands, Zexion was sent to see if any of Scar’s followers escaped the battle. As it turns out Zira, who was Scar’s wife at the time, escaped with a small group of followers. She vowed revenge on the Republic and to those who brough Scar down. Zexion saw this as the perfect advantage to benefit for the Order. The Order started to help rebuild Zira’s army, but they did not have enough time to do it. Zira did mention that Scar was secretly build a powerful super-factory called the Star Forge. When Xehanort heard about it he was surprise since the orginal Star Forge was destroyed almost 4000 years ago. She also mention that the Star Forge was halfway through contruction when Scar was defeated. The XII Order was able to the bring the Star Forge full production in only a matter of months. They had to be sure that the Republic does not know about the new Star Forge and their involvement in the conflict between the Outlander Army and the Republic Clone Army.
Saïx: The second Frontier Agents and number VII in the XIII Order. He has an X-shaped scar on his face, which he received from a past war, and wields a gigantic claymore. He controls the element of moon and the Berserker Nobodies, who wield weapons much like his own. His powers and fighting style are most likely a play on lycanthropy. When the Order learned of a lost treasure that was stolen by Redbeard the priate was on Southern Bayou, Saïx when there to find it. There he runs into Injur’n Joe, a mean bear with a very nasty attitude to boot. Seeing this kind of power, Saïx joined up with him to find the lost treasure that is supposed to be on this world.
Axel: The third of the Frontier Agents and number VIII in the XIII Order. In battle, he utilizes a pair of chakram as well as the element of fire. The Assassin Nobodies are under his control. He is a skilled manipulator and one never quite knows whose side he is really on. Axel discovered Pete, who was trapped in the shadow realm at the time and the two became inseparable. Their main obtective was to recruit more villains to join the Order. After Sora and Riku interfered in one of their plans, their new goal was to stop them from ruining their plans. Dispite the fact that they constantly screw up and get their butts kicked very time, they are very persistent in their work.
Demyx: The fourth of the Frontier Agents and number IX in the XIII Order. He uses a sitar as his weapon and controls the Dancer Nobodies. He does not enjoy fighting, but can control water with his sitar to replicate himself and to execute powerful and intimidating attacks. He is normaly a big coward and not that much of a fighter. When the Order began looking for the Descendants of Light, Demyx when on his own to find them. He had no clue that he would find one a lot sooner than he thought. After his failure in Paris, he is paired up with other villians or Order members.
Luxord: The fifth of the Frontier Agents and number X in the XIII Order. He loves to gamble and sees battle as just another form of it. Like Zexion, he is more a strategist than a powerful fighter. He has neatly ordered blond hair, a short beard and several earrings in the shape of the Nobody symbol. Luxord uses a deck of 52 gaint playing cards and the element of time. He is in control of the Gambler Nobodies. When Luxord came to Halloween Town, he immediately revived Oggie Boogie with the help of Shock, Lock and Barrel. He soon found out that jack was gone searching new discoveries for next years halloween. After taking over Halloween Town, Luxord suggested to Oggie; “why rule over Halloween when you can rule over all seven holidays?” With Luxord’s help, Oggie began his conquest to become the seven holidays king.
Marluxia: The sixth of the Frontier Agents and number XI in the XIII Order. he wields a pink scythe and the element of flower (referred to as "nature" in some official material; the meaning of nature does not exactly correspond to the powers Marluxia possesses). Marluxia has full control over the Spectre Nobodies. A lot of mystery revolves around this character. He claim he found a way to cheat death, but no one knows if this is true. When Marluxia received his Shadow Stone, he though it wasn’t enough, he want even more power. When he learned of the Forbidden Arts, the magic that can grant the user the power to create, change and destroy, Marluxia wasted no time finding it. He soon met the creator of the Forbidden Arts, an exlied wizard by the name of Rothbart. He gives the Arts to Marluxia under one condition; that he wold help Rothbart capture a certain princess that he’s been after. Marluxia accepted and gained more power than he realized.
Classified Information: Although Marluxia was defeated by Sora and Riku, that wasn’t the real thing. The one they destroyed was only a copy of Marluxia. The real Marluxia died 11 years prior to the game. Back then there were three powerful nations that were at war with the heartless army: the Galactic Republic, the Allied Kingdoms of Bretonia, and the Sovieon Empire. At that time Marluxia was acting as a double agent to spy on the Sovieon Empire. Posing as a prophet, with the help of Rasputin, he was able into obtain some valuable info about the Romanov loyal family. After begin exposed and exlied from Sovieon territory, Marluxia and Rasputin swore revenge on the the entire famliy. To do this they both sold their souls to the drak forces to obtain ultimate power. Rasputin recieves a reilquery that allows him to control the powers of the Shadow Realm, while Marluxia received a corrupted version of his scythe which allows him to summos vast armies of heartless. With these powers in hand, they launch a surpise attack the loyal palace. Marluxia wanted to be sure that their mission is a success by killing Anastasia Romanov. He and Rasputin almost succeed, but were thwarted by King Mickey and collapsed in an icy lake. Both Rasputin’s reliquery and Marluxia’s scythe were the only things that were recovered.
Larxene: The seventh and final member the Frontier Agents and number XII in the XIII Order. She is the only female member in the entire Order. She is an arrogant sadist in nature, abrasive and uncaring for the feelings of others as she enjoyed seeing them suffer with her mindgames. Larxene uses the element of thunder to fight and wields throwing knives held between her fingers as her weapons. Compared to the other members, she is incredibly agile in battle. While visiting the Shadow Realm, she ran into a tiger named Shere Khan who was trapped behind a flame barrier. He says that he was sealed here by one of the Elemental Sages and remained here ever since. Feeling sorry and needing a partner, Larxene breaks the seal and frees Shere Khan, and in return helps Larxene find a new world to conquer.
