Bloodcurdle

Bloodcurdle (凝血) is a Quirk used by Chizome Akaguro.

Description
This Quirk allows Stain to paralyze an opponent by ingesting samples of their blood.

When Stain gains access to his target blood, he can immobilize them for a limited period of time, leaving them vulnerable to a finishing move. Stain facilitates his access to blood by using sharp, long-ranged weaponry like swords, which tend to become stained with blood after cutting through tissue.

The amount of time a victim remains paralyzed depends on their blood type in relation to Stain's own. In Stain's case, blood type B represents the longest amount of time, then decreasing to AB, A and finally O for the shortest amount of time. Regardless, the maximum amount of time anyone can stay paralyzed for is 8 minutes.
