Bestiary
Lingering dream of a fallen warrior. Executed for crimes against the King.
A life defined by tragedy and triumph. A death marred by sorrow and regret. A spirit burdened by sins and memories. Better to wander the world than be cursed with glory.
-Xero
Dialogue Bottom

Xero is a Warrior Dream boss in Hollow Knight.

Xero was a warrior of Hallownest who believed that strength would always allow him a bright future.[1] When his mind was infected, he hoped to fight against the plague with violence.[2] Fueled by the same hope, he turned against the Pale King, for which he was executed.[2][3] Xero was buried in the Resting Grounds, his tomb a reminder to any who would betray the King.[4] When his ghost awoke, he still could not see the wrongness of his actions and believed instead his demise to be the result of a doomed fate.[2]

Xero's ghost appears to the Knight once they have acquired the Dream Nail. He accepts their challenge to mock his own fate. Once defeated, Xero finally acknowledges that his actions against the King were irrational.[5] The ghost confides to the Knight its faith in their bravery, before shattering in 100 Essence to be collected by the Dream Nail.[5]

Behaviour and Tactics

Xero only has one attack:

  • Nail Cast: Xero will spawn in 2 glowing Nails. While floating around he will constantly shoot out one of his nails in the Knight's direction and will draw it back. He will shoot a Nail every 1-2 seconds. Coming into contact with the nail while it's being drawn back still can deal damage. At 50% hp Xero will spawn 2 more Nails and his attack pace will increase to 0.75 seconds between each Nail Cast.

If the Knight stands slightly away from Xero when they fire their nail, then dashes to directly below them in the first phase, the nail can be easily avoided.

The Knight can heal easily by running off the platform and to the far left of the area, where Xero's attacks will not reach, or by running under the platform. Note that this is not possible when fought in Godmaster Icon Godhome.

Dialogue

Dialogue

First encounter Stop there! Those who try to leave this kingdom are cursed. Better to rest here, until time itself sleeps.

Hope, and freedom... I thought that strength alone could grant me these things. In my dreams, I would cut that plague with my nails, and then I turned my weapons upon the King.

When I awoke in this sacred place, I began to understand. Those who hope...are already doomed.

Do you still hope, wanderer? Will you flee? Or will you raise your weapon and doom us both?

Listening again Do you still hope, wanderer? Will you flee? Or will you raise your weapon and doom us both?

When listened to Ah... I can see now. Those who turn against the King are doomed as soon as they raise their weapon.

Do not call me a traitor... Simply call me a fool.

I know you will not flee. Wherever you go... I will be watching.

On his tomb Cursed are those who turn against the King.
