Womb

Womb, full name Ragnarok: Womb, is a Ultimate Move performed by Fumikage Tokoyami using his Dark Shadow Quirk.

Description
Fumikage summons an enlarged Dark Shadow towards an opponent, who then wraps and swaddles itself around the target, preventing them from escaping. This technique was first used to restrain Izuku Midoriya.

Fumikage said the move was inspired by Izuku's strategy during their participation in the Cavalry Battle.
