Loki is a boss found in the Depths. He resembles a red demon Baby with four arms, small horns and The Mark on his forehead. In Wrath of the Lamb, a posthumous version of Loki called Lokii appears as a boss in The Womb and Utero, appearing as Loki split in half.
His main attack has three steps. He makes poses whilst attacking. First, he shoots 4 projectiles in a plus shaped pattern, followed by 4 shots in an X shaped pattern, and finishing with another 4 shots in a plus shapped pattern. His other attack shoots 8 projectiles in a circle around him.
He also randomly teleports himself during the fight.
- It is rare to find him as a boss. He is, however, very common in Sheol (encountered in pairs) and sometimes can be encountered in The Womb. He can be encountered in triplicate in The Chest.
- Loki is also referred to as "Baby Demon" and "Fetus Demon" in the Unholy Edition art booklet.
- During developement Loki's codename was "Mr.Cool". 1
- It was confirmed by Edmund on Formspring that Loki indeed possesses two pairs of arms.
- In Norse mythology, Loki is the god of mischief and chaos.
