This is a guide listing all of the Unique Monsters in Xenoblade Chronicles 3. These aren't new to the series; each past Xenoblade entry has had these specially-named optional bosses that can be found practically anywhere out on the game map.

Luckily, unlike Xenoblade Chronicles: Definitive Edition, there do not seem to be any missable Unique Monsters, and every region will remain explorable up until the end of the game. So feel free to explore at your leisure as you play through this massive RPG, and check this list for reference when & if you need it.

Now, what is Soul Hacking? This gameplay mechanic is new to Xenoblade Chronicles 3, and it is related to Unique Monsters. However the mechanic doesn't appear until Chapter 5, when you recruit the optional hero Triton.

Triton class is Soulhacker, which uses enemy abilities somewhat similar to a Blue Mage in the Final Fantasy series. The Soulhacker class starts out with a few, but you earn the rest by defeating Unique Monsters with a Soulhacker in the party. So, we include when each monster's Soul Hack ability is in the list below. [This does mean once you unlock the Soulhacker class in Chapter 5, yes you do need to re-fight every Unique Monster you've already beaten to learn its Soul Hack ability. It's kind of tedious]

The Xenoblade Chronicles 3 Unique Monster List can be found below.

Note, we are still looking for 5 Unique monsters in the game, and we'll update when we can!
