Scolex is a boss that can appear in the Womb and the
Scarred Womb.
Behavior[]
Scolex is only vulnerable in his blinking tail segment. He burrows into the ground before performing the following attacks:
- Jumps out of the ground towards Isaac, burrowing back into the ground at the end of the jump.
- If Scolex is hit by an explosion while mid-air, he will be deflected backwards.
- Partially emerges head-first and shoots out a cluster of projectiles towards Isaac, similar to
Monstro, but with a wider spread.
- After performing this attack, Scolex will always jump out of the same spot he entered.
- Partially emerges tail-first and fires cluster of 3 red
Ipecac shots towards Isaac.
- After performing this attack, Scolex will always jump out of the same spot he entered.
Scolex deals a whole heart of contact damage.

Trivia[]
- Scolex appeared in the original The Binding of Isaac.
- Scolex is the only Boss to have lost access to a Champion variant in an update. Specifically in Repentance, where his dark grey counterpart is inaccessible unless using Console commands to summon it.
- Scolex can be considered an older or younger version of
Pin, but not a posthumous one (that title goes to
The Frail).
- A scolex is the name of the head of a tapeworm.
- Compared to the original Binding of Isaac, Scolex's head and tail attacks are swapped.
- Scolex bears some resemblance to a mythological Mongolian Death Worm, which are described as long, scaly, and blood red. It also raises half its body out of the sand and covers its prey with a lethal acidic substance, which is somewhat similar to Scolex's head attack.
