Alien Arbiters is the Space Deadly Alliance and the team member of the UN-GDI and the Galactic Alliance. The team of Xeno-Knights from the mysterious planet fight for the honor of the Houses against the Syndrome Invaders and the evil Weiyan-Yutani Corporation from exploiting their heritage.
In the mysterious planet known as LVX-117 on the Xeno Galaxy, Leecharik was a squire for a knight of the House of Lenxiang and he had served him for good few years. But, he doesn't want to be a knight because of the responsibility and so much duty until the knight was accidentally killed and fled from the House as a squire but not a knight except he took the armor and two-bladed staff. This was his chance of his freedom.
For years of his self-imposed exile, Leecharik travelled across the planet, adventuring his whole life of freedom while looking for some quests from city to city for days and fighting hostile factions from other planets seeking for resources though he's still a squire. On his way to another city through the jungle forest, he spotted the illegal site from the Black Cobra and foiled their illegal activity and freed those creatures before could be sold to the black market. Before he finished his remaining foes off, he was intervened by Kifra, the bounty hunter and the Xeno-Knight from the House of Kafran. Leecharik thanked for help and continued his journey to another city while Kifra was curious about his personality. Then, on the open desert wasteland, he spotted another Xeno-Knight but a mercenary knight named Zarog of the House of the Xeno-Exile, battling the marauders and Leecharik joined the fight but then during the fight, things went into haywire when Zarog interrupted his cool moves, viewed as disgust by Zarog himself, and shown to him of being a serious Xeno-Knight like himself. After the battle, Leecharik reacted by telling him that he was pretending a knight while he's still a squire and it shocked to Zarog, Kifra and Chorock of the House of Rockscale. And with that shocking and surprising truth, they brought Leecharik to Zarog's ship where he meets other Xeno-Knights like Kazer of the House of Razur, Heraldroc of the House of Roycell, Arekon of the House of Ironxen, Scorikus of the House of Scourgus, and Polkar of the House of Xenzard.
After the explanation from Leecharik of why he don't want to become a knight, he was trained by his new friends, taught him to use his new skills as well his own by the book he wrote during his self-exile. After his training is completed, they set forth to the city of Ancheros where they've carried out their several jobs from contractors of each houses, disrupting the evil and illegal activities by the evil Weyian-Yutani Corporation and stopping the Black Cobra's terrorist activities as well battling the marauders and pirates. During their duty as the Xeno-Knight mercenaries, Leecharik was spotted by the members from his House and he's needed to return to them the most as well his fellow Xeno-Knights for their services. However, Leecharik refused to return to the House after that accident but it doesn't matter anymore and it wasn't his fault after all. Leecharik accept the request and travelled to the House of Lenxiang.
At the House of Lenxiang, Leecharik and the Xeno-Knights were tasked to avert the alien slavers known as the Hexusians from Planet Hexus, one of the Syndrome Invaders' evil allies, and their conquest on the Colony X-043 where the refugees and the colonists were besieged by them. Their mission was to free the slaves and incite the revolt against the alien slavers, requested by Hexus's nemesis race known as the Thothians from Planet Thoth, but the only problem is that the slaves are the Siphorians and they won't listen to the Thothians but it may be listen to the Xeno-Knights if possible. As they were about to leave for their task, Leecharik is now officially knighted by the House but under one condition: he'll remain a squire but that doesn't changed that as he's known as the Squire-Knight of Lenxiang. Leecharik accepted the Xeno-Knight's title and begins their quest.
At the Colony X-043, they've infiltrated through the underground tunnel and found the slaves at the prison. As they were about to incite the revolt, the slaves refused to fight because the Hexusians have their wife and children hostage and they'll be sacrificed for their evil god if they disobey their order. So the Xeno-Knights freed the hostages and disrupted their unholy ritual as well disabling their defense system. With the hostages are freed and safely escaped from the colony while the rest of the slaves now liberators joined the fight, the Xeno-Knights lead the revolt against the alien slavers. The revolt was a success as they've fought their way to secure the colony from storage facility to barracks to residential area to the headquarters. During the battle, their Aura was slowly to awaken as they're fighting for their good deeds as the Xeno-Knights and fighting for their heritage. Then they've reached their last stand at the plaza where the Hexusian leader was about to attempt to escape but the enemy leader was forced to fight rather than flee as cowards. Then suddenly, Leecharik's Aura is unlocked by his will and courage and honor and defeated the Hexusian leader in a single strike then forced the remaining enemy forces to surrender immediately until the Galactic Alliance intervene and secured the colony. After the battle is over, the Xeno-Knights were thanked by them and they're now part of the Galactic Alliance for their heroic deed as they continue their adventures. But as for Leecharik, his lifetime adventures for battle between good and evil has already begun.
On December 23rd, 2012, the Xeno-Knights have joined forces with their fellow allies from the Galactic Alliance to battle against the Monarch Invaders and helped the Deadly Alliance to defeat the Monarchian Queen.
After the defeat and the fall of the Monarch Empire, the Xeno-Knights were offered by the UN-GDI to join the UN Paranormal Division which they've accepted but they continue to reside their home planet in the Xeno-Galaxy.
