Warping

Transmission is a stolen Quirk from an unknown person used by All For One.

Description
This Quirk can produce a black liquid that acts as a portal, similar in nature to Kurogiri's Warp Gate. Also similar to Warp Gate, this black liquid can also teleport people by engulfing them whole. It appears All For One can use this Quirk on a large scale as he can produce multiple black liquid portals.

This Quirk, however, has many limitations; it is not a coordinate-based warping Quirk and can only warp things to and from the user's location. Also, the warping only works if it is used on someone with whom the user has a close relationship. The exact details are unknown, but All For One manages to use it on Gran Torino simply by identifying him as Nana Shimura's friend.

It appears that All For One requires his left arm to be able to use this Quirk as he was shown being unable to when All Might crushed it.
