It acts like Fistula, but spawns 3 medium sections instead of 4. Teratoma also spawns small Spiders when the smallest part of it is destroyed. It is a boss in The Womb I and Utero I . Total HP: 60 (large) + 3x15 (medium) + 6x8 (small) = 153
- Be careful to not split off too many parts at once. This could impair your ability to dodge.
- Anything that damages multiple enemies will help you speed up the battle (especially when a larger amount of sections are present on the screen)
Eternal Teratoma acts exactly the same as its original counterpart, but it shoots bullets on death.
When the initial large Teratoma is destroyed, it releases 4-way bullets.
When the second medium Teratoma is destroyed, it releases 6-way bullets.
When the final small Teratoma is destroyed, it releases 8-way bullets and spawns Spiders.
- In biology, a teratoma is a tumor like growth that contains normal tissue from each of three germ layers (like hair, teeth or even bones). Like Fistula, these medical facts reference to their appearance (note the bones around Teratoma).
