Zeon

Zeon is a Hero in Xenoblade Chronicles 3. He is a soldier from Keves and the Commander of.

Story arc
Zeon is present during Colony 9's battle against Colony Sigma at Everblight Plain. He can be seen riding into battle on top of an Equites-type Levnis.

Before the mission to Alfeto Valley starts, he advises Noah, Eunie and Lanz to stay vigilant, the Consul coming all the way to Colony 9 to discuss with the commander making him think the mission isn't an ordinary one.

When Noah, Eunie and Lanz are labeled traitors and the Colony 9 commander is forced to take the fall for their actions, Consul B appoints Zeon as the new commander.

Where the Heart Is
Later, the party ears rumors of Colony 9 being surrounded by Agnian forces and comes back to defend it. On their way, they're intercepted by Zeon, who orders their arrest. Their fight is interrupted by a report of an Agnian battalion attacking Colony 9. After a moment of hesitation, Zeon decides to allow Noah and the others to join him to defend Colony 9, and brings them back with him to Colony 9 Command, where Kite updates them on the Agnian soldiers's movements. Kite and Zeon clash about how to deal with the situation, until Kit storms out of the room, angry at his commander's decision to integrate Noah and his companions in their forces. Zeon then exposes his plan to the party, sending them as the vanguard against Agnus, under his personal supervision.

On their way to Everblight Plain, Eunie reminisces on how Zeon used to be someone who support people who try their hardest and help people in need. Zeon says he understands they must have their reasons for rebelling against the Colony, but he can never be the friend he once was to them. Noah retorts not being able to go back to how it was doesn't mean they cannot build something new. Before the battle begins, Zeon warns he will be too busy fighting for Colony 9 to look out for possible deserters, implying he won't come after Noah and the others if they choose to take the opportunity to escape. This makes Lanz angry, and he and Eunie and Noah reaffirm their wish to fight for Colony 9, no matter what Zeon thinks of them. They head into battle, fighting off the Agnus Strike Force until their captain is defeated. Zeon allows the Agnian survivors to escape, and the Agnus captain criticizes his decision as too soft for war before dying, warning Zeon he'll learn that lesson the hard way. His words strike a chord in Zeon, who recalls saying a similar thing to Noah in the past.

On their way back to Colony 9, Noah explains all they've learned about the Consuls and the Flame Clock to Zeon. Upon arriving to the Colony, they are met by Consul B, who comments on Zeon's good work and mocks the deserters, as well as the soldiers who died for nothing. Angered by his words, Zeon defends the party when the Consul attacks them, then counterattacks and gives Noah an opening to destroy the Colony 9 Flame Clock. Consul B transforms into Moebius B, and is soon defeated by Zeon and the party. Zeon then explains everything he has learn from Noah to Kite and the rest of Colony 9, and asks them to give Noah and the others a chance. Most of them agree, but Kite storms off, claiming he is the only one fit to be commander, not Zeon. Zeon doesn't take offence, believing in Kite's wish for the good of Colony 9. He then exposes his plan for the future of the colony, starting with solving the food shortage by making fields to grow their own food supply. He knows it will be difficult and that people won't trust him easily, but he doesn't care for what others think about him as long as he can carry out his duty. He thanks Noah and the others for their help, and offers to lend them his support whenever they need it.

Other appearances
