Hero

Heroes are non-playable party members in Xenoblade Chronicles 3. By either progressing the main story or completing s, these characters can be recruited by the party and used as a seventh party member. Outside of the Archsage's Gauntlet, only one Hero may participate in battle at a time. Each Hero has a unique, which can be unlocked for use by the main party.

While recruiting Heroes is mostly optional, some Hero Quests are part of the main story, thus making those heroes mandatory.

Trivia

 * Heroes will have different voicelines when being chosen on the Hero selection menu once reaching to the final point of the main story.
 * While certain Heroes like Monica and Ghondor becomes temporarily unselectable during certain parts of the main story, Ethel is the only Hero who remains that way until her ascension condition is met.
 * Ethel and Cammuravi are the only two Heroes that doesn't have an Ascension Quest, as well as the only two that share the same ascension condition.
 * Both are also the only Heroes to be killed by Consuls and be reborn in the main story.
 * Ghondor is the only Hero that neither needs a Hero Quest completed nor going to a certain location to acquire. Miyabi is similar in that she is gained from somebody else's Side Story.
 * Ino and Masha are the only Heroes who will not assist the party in the final battle, due to being DLC content.
 * Riku & Manana, Nia, and Melia are the only non-DLC Heroes that can never be fought by the party.
 * All non-DLC Heroes with the exception of Triton appear as part of the ending cutscene, regardless of whether they're recruited (or in Ethel's case re-recruited). This is due to the scene being pre-rendered.
