Loki

Boss

Double Trouble

Degraded Boss

This article is about Loki, not to be confused with Lokii

Loki is a boss that can appear in all environments of Chapter 3. He appears as a small red demon with The Mark on his forehead.

Behavior[edit | edit source]

Note: A Poky or a Slide may accompany Loki during the fight, which moves around the room at random.

Shoots bullets in the four cardinal directions, followed by the four diagonal directions, and then the cardinal directions once again.
Teleports to another random location in the room.
Spawns a Boom Fly on top of himself.
Shoots eight bullets in all directions.

Immediately concentrating on the Boom Flies when Loki spawns them gives you a chance of causing them to explode on him.
The Poky in the room does contact damage and has very random movements, so be sure to keep an eye on it so it does not damage you by surprise.
All of Loki's bullet attacks have a simple pattern that can be easily avoided if you move back from him when he makes an "oh" expression.

Loki appeared in the original The Binding of Isaac.
The spike block in the room does not damage Loki's Boom Flies anymore as it did in the original game.
Loki's "mark" (The numbers 666 on his forehead) is more noticeable than his appearance in the original game.
Loki has a posthumous version of himself named "Lokii," which appears in Chapter 4.
Loki is based on the Norse trickster god of the same name.
Edmund McMillen loved Loki's design so much that he made Little Horn.
