Leeches are worm-like enemies which are commonly found in The Womb, Utero and sometimes in The Depths.
Behavior[]
They float around the room at random and charge at Isaac in a manner similar to Chargers. However, unlike Chargers, they are flying, and thus will pass over obstacles until they hit the opposite wall; they also charge at a much faster pace.
Gallery[]
A Leech stuck inside a wall. Could only be damaged by Ghost Baby.

Bugs[]
- If a Leech charges at you while it's aligned with a door, it will go through it and off the screen, until it eventually reappears when its charge ends.
- Occasionally, when you damage a Leech, it will turn into a Holy Leech. This can happen in The Womb but the chances of it happening is extremely rare.
