Using this Quirk, Kurogiri can create and manipulate a dark fog that acts as a portal.
When the user produces a mass of the dark fog, it transports anything it comes in contact with to a nearby location. Kurogiri can even shroud himself with the black mist to hide his true body and personally transport anything out of himself.
It is said that this ability is a very rare type of Quirk, making Kurogiri invaluable for the operations of the League of Villains, as not even Tomura Shigaraki dares to get rid of him in case of failure.
Should a warp gate close while someone is stuck half-way through, the person will be cut in half.
Its main weakness is that a part of the user's real body must be present at all times in order to release the fog in the first place, allowing foes the opportunity to hit or immobilize said part, and by proxy, the user themselves.
Another weakness is that portals created are coordinate-based (unlike Warping) and thus to open them, the user must be able to pinpoint the exact position where he wishes for each portal to open up into but can open them based on sight and usually only needs coordinates to open up in areas he cannot see. Due to this, the user cannot search for missing comrades if he does not know their exact location.
