Big Horn is one of the bosses added in the expansion The Binding of Isaac: Afterbirth †. He is an adult version of Little Horn.

Behavior

Big Horn alternates between attacks from his head and attacks using his arms. His head and arms pop out of holes in the ground. Before attacking with his head, Big Horn will do nothing for a few seconds, allowing Isaac to deal damage under no direct pressure.

Head Attacks:

• Spits out a large ball that homes in on the player, attempting to deal contact damage.
• Spits out two balls that bounce against walls and deal contact damage. These do not home.
  • Occasionally does both ball attacks at the same time.
    • The balls can hit and damage Big Horn, destroying themselves in the process.

Arm Attacks:

• Goes underground, hiding his head, then spawns two or three holes. Each hole will either have an empty hand, a hand holding a bomb, or nothing.
  • If a hand holds a bomb, Big Horn will throw it at the player. Possible thrown bombs include 1-3 Troll Bombs, 1 Mega Troll Bomb, or 1 Hot Bomb.
  • If a hand is empty, it will follow Isaac and attempt to smack him three times.
  • Extremely rare chance to spawn a low-health version of Little Horn during this.

Notes

• Rarely, Big Horn can throw 5-6 Troll Bombs at once (including Mega Troll Bombs).^{[citation needed]}
• The hot bombs are not affected by Safety Scissors.
• After attacks where Big Horn opens his mouth, there's a very small window where bombs can be kicked into his mouth. If fed a bomb, Big Horn will take damage, be temporarily stunned, and play a unique animation, during which he will take 20% more damage.
  • This is easiest to do with Dr. Fetus.
• If Isaac touches Big Horn's Hot Bombs in Chapter 4 and beyond, they will still only deal half a heart of damage instead of a full heart.
• Big Horn's hands have arbitrarily high health (10,000) and all damage dealt to them is applied to Big Horn.
  • Because of this, Big Horn will die instantly if Isaac uses Sharp Straw while his hands are out.

Trivia

• Big Horn and Little Horn, with their ability to create pitfalls, share similarity to the Pokémon Hoopa, a Legendary Pokémon that creates dimensional wormholes to travel from one place to another. Hoopa also has a bigger form, furthering the similarity.
• Upon defeat, Big Horn frowns and retreats back into his hole. He does not explode into blood upon defeat.
