Binding of Isaac: Rebirth Wiki
Advertisement

Knights are enemies that can normally only be damaged from their exposed brains on the backs of their heads. However, explosions, attacks that pierce enemies (Collectible Brimstone iconBrimstone, Collectible Cupid's Arrow iconCupid's Arrow, etc.), or melee attacks ((in Repentance)Collectible Spirit Sword iconSpirit Sword, Collectible Mom's Knife iconMom's Knife, etc.), will deal damage from any direction. The Knight normally walks around in random directions and will dash at Isaac if he is within line of sight.

Variations[ | ]

Selfless Knight[ | ]

Selfless Knights are considerably faster than regular Knights but otherwise function the same. Rather than an exposed brain, they have Isaac's face on the backs of their heads.

Floating Knight[ | ]

Floating Knights are similar to ordinary Knights but are slightly slower and can fly over obstacles.

Bone Knight[ | ]

(except in Rebirth)

Bone Knights are similar to ordinary Knights but leaves behind a short-lasting trail of damaging Red Creep. They charge faster than an ordinary Knight, but not as fast as the Selfless Knight. (except in Repentance) Bone Knights are the only variant of Knights that are susceptible to knockback both from the front and from the back.

Loose Knight[ | ]

(in Repentance)

Loose Knights are similar to ordinary Knights, but move slower and separates into a Brainless Knight and PonPon when killed.

Brainless Knight[ | ]

(in Repentance)

Brainless Knights are a variant of Knight created when a Loose Knight dies. They alternate between running around the room along the cardinal directions and aimlessly walking in circles, charging at Isaac when he gets in line of sight. It dies when its corresponding PonPon dies; otherwise, they are invincible.

Black Knight[ | ]

(in Repentance)

Black Knights are a variant of Knight that have slightly higher health and will walk erratically around the room, charging at Isaac if he is within line of sight. When charging, they accelerate rapidly, sending waves of fire in the cardinal directions and becoming stunned momentarily after colliding with a wall or obstacle. A Black Knight's mask will also reflect any of Isaac's tears that come in contact with it. They are almost immune to knockback and other forced-movement (such as Collectible Black Hole iconBlack Hole).

Notes[ | ]

  • The Knight is a monster in two segments: an invisible, invincible "shield" segment that leads the way and the visible "body" that follows close behind. The shield takes no damage and partially covers the body, stopping shots that would damage it.
    • Sometimes, when a Knight changes directions, it appears to pause for a moment; this is because the shield segment is moving past the body segment, and the body won't move until the shield moves away from it, the same way the trailing segments of Boss Larry Jr. ingameLarry Jr. or ButtlickerButtlicker chains behave.
  • (in Afterbirth † and Repentance) Prior to Booster Pack #5, the Knight and its variants were briefly invulnerable when they spawned, or when Isaac entered the room they are in. They would become vulnerable when they started moving.
    • In the original Binding of Isaac, Knights were completely vulnerable when they spawned; the shield segment did not cover the Knight's front until it started moving, so Isaac could shoot it in the face for damage as soon as it appeared.
  • Items that provide a fear effect (like Collectible Dark Matter iconDark Matter) work remarkably well because they run away from Isaac, exposing their weak side.
  • Items that have a damage-over-time effect (such as Collectible Fire Mind iconFire Mind or Collectible Scorpio iconScorpio) Also work well, since hitting them on the shield portion will still inflict the effect and mitigate the need to hit them from behind.
  • The name of the monster is a reference to the Darknut (also known as Tartnuc) enemy from The Legend of Zelda who, similar to Knights, cannot be harmed from their front.
  • Floating Knights cannot fly over key blocks.
  • If Isaac charms a Knight and it is the only enemy in the room, the Knight will chase Isaac but will not charge, making the Knight more difficult to damage until the effect is gone.

Trivia[ | ]

  • (in Repentance)The Black Knight, Brainless Knight, and Loose Knight first appeared in the Antibirth mod.
    • In Antibirth, Brainless Knights were referred to as Empty Knights.
    • Black Knights had a slightly different appearance in Antibirth and would spawn in the Mausoleum.

Bugs[ | ]

Bug Bug! The hitbox of Dark Red Champion Knights (and their variants) do not change when they crumble into goo, and they must be shot from the back to damage them.
