Rex

Rex is the main protagonist of Xenoblade Chronicles 2. He is a salvager and the Driver of Pyra and later Mythra, the Aegis. His goal is to take them to Elysium to fulfill their dream and save Alrest from its fall.

Appearance and personality
Rex is a teenage boy with brown hair and yellow eyes. He wears a blue diving suit with brown and gold accents, mainly for use during his salvaging work.

Rex is enthusiastic, but inexperienced at anything outside his line of work, and rather naïve.

Story arc
The story opens with Rex salvaging out of the Cloud Sea of Alrest from aboard the small titan Azurda, whom he calls Gramps. Rex is worried about the titans dying out, which seems to be happening more often lately, and whether the fabled Elysium of the World Tree truly exists. The two go to the Argentum Trade Guild so Rex can sell what he salvaged. While there, he is unexpectedly summoned by, Chairman of the guild. Elite salvagers from Leftheria have been requested by a picky crew, and a huge sum of money is involved. There is some dissent amongst the rest of the crew over accepting Rex - he butts heads with Nia and has to defend himself from Malos, but they board the C.S.E.V. Maelstrom and move out.

The target ship is located, Rex and the other salvagers raise it, and the search begins. Jin decides Rex should join the search, so he does. The search crew finds doors blocked by what Jin calls "Addam's Crest", which will only open for a Leftherian, so Rex is ordered to open them. As he is therefore the first to enter, he is the first to reach the treasure inside: a woman sealed in a glass compartment in the wall. Intrigued, he sees a glowing green crystal on a sword stuck in the ground before him, and touches it despite Malos yelling at him not to. Jin instantly kills him and destroys the sword in an "act of mercy".

Rex wakes up in a grassy field, seeing the sealed woman standing beside a lone tree. Her name is Pyra, and she says they are in Elysium - or rather, a memory of it. She wishes to return to Elysium, and revives Rex using half her life force, making him her Driver. Part of the Core Crystal appears in Rex's chest, and the Aegis is recalled into his hand. He helps Pyra break free of Malos, and the two fight him off so the other salvagers can escape. Nia and her Blade Dromarch join Rex's side, and a mysterious black ship's arrival is countered by Azurda's appearance. Rex, Pyra, Nia, and Dromarch all escape on Azurda, but he is shot down and crashes on Gormott.

As a party member
As the main character of the game, Rex is the Driver playable for the longest time. He is the only Driver who can wield the Aegis Sword (not including in Torna ~ The Golden Country) and the Catalyst Scimitar. In chapter 7, can be called exclusively by Rex, making him especially strong in s. He also becomes the Master Driver in chapter 8, allowing him to use any Blade (except for any of 's Blades).
