You Will Know Our Names

You Will Know Our Names (originally unofficially referred to as Those Who Bear Their Name) is Disc 4, Track 9 on the Xenoblade Original Soundtrack and Track 7 on the Xenoblade Chronicles Special Soundtrack. It plays during fights against s. It also plays in certain cutscenes, where it then acts as the battle music to the subsequent fight:
 * The scene on Prison Island when Shulk obtains the Monado II and then fights Metal Face
 * The scene at Agniratha when Meyneth declares a plan to free Gadolt from Egil's mind control
 * The battle at Colony 6 when Shulk arrives to help against the invading Telethia
 * The scene on Prison Island when the party regroups in the middle of the fight against Dickson

As part of a promotional video for Xenoblade Chronicles 3D, this track was rearranged by Tomori Kudo.

The piece was performed on both day 1 and day 2 of Nintendo Game Music Live!, a series of performances of Nintendo music by rock band and big band as part of the Nintendo Switch Experience event on 14/15 January 2017. In both performances, the piece was given a substantially different structure, including entirely new sections.

In other Xenoblade games
In Xenoblade Chronicles 2, You Will Know Our Names plays during battles against s if the DLC-exclusive s or  are in the active party. However, if is also in the active party, Uncontrollable will play instead unless Elma is linked to a secondary party member and Shulk or Fiora is bound to the primary party member.

A different track in Xenoblade Chronicles 2, You Will Recall Our Names, was named after You Will Know Our Names. Likewise, a track in Xenoblade Chronicles 3, You Will Know Our Names - Finale, was also named after this track. Both fill the same purpose — they are a battle theme for unique monsters and, in the former's case, select story bosses.

Dialogue in-universe makes reference to these tracks:
 * In Xenoblade Chronicles 2, the references a situation where "10-ton gorilla with fancy name appear from nowhere and start playing electric guitar", which references Territorial Rotbart as well as You Will Know/Recall Our Names' opening instrument.
 * In Xenoblade Chronicles 3: Future Redeemed, A may say "We will know its name for certain" when the player targets a unique monster.
