Trivia[edit | edit source]
- Teratoma was added in the Wrath of the Lamb DLC for the original The Binding of Isaac.
- A teratoma is a tumor that contains tissues that are atypical for its placement in the body. This can include hair, teeth, bones, and so on.
- Unlike other posthumous bosses, Teratoma is found 3 chapters away from its base boss, Fistula.
- Unlike the original Binding Of Isaac, Teratoma doesn't bounce off of Rocks.
- Teratoma is one of the three bosses that can be spawned by It Lives, the other two being Chub and Polycephalus.
- Because of this, Teratoma is the only boss that can both appear as a boss and be spawned by another boss in the same chapter.
