Lokii is a posthumous version of Loki that can be found in The Womb and Utero.

Defeating Lokii for the first time unlocks Loki's Horns.

Behavior[edit | edit source]

The fight against Lokii is similar to fighting two Lokis, with each half having the same attacks:

  • Fires tears 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 Red Boom Fly on top of himself.
  • Shoots eight tears in all directions.

Notes[edit | edit source]

  • The only real difference between Loki and Lokii is that Lokii spawns Red Boom Flies instead of normal Boom Flies.

Trivia[edit | edit source]

  • Lokii's name is a pun on the Roman numeral for two, II.
    • It can also be a reference to the scientific plural suffix "ii" such as in "radii" and "virii" that is not commonly accepted.
  • The boss art shows Lokii with no arms despite Lokii's sprite in-game having arms. In addition, the boss art doesn't depict Lokii's marks on their foreheads.
  • Both Lokii halves have the same sprite, just flipped horizontally.
