Blackwhip

Black Whip is a Quirk used by a previous user of One For All and was passed on to Izuku Midoriya.

Description
Black Whip is described as a top grade Quirk useful for capturing enemies and increasing one's own mobility. The Quirk allows the user to generate black tendrils from their arm and command them at will.

However, when Izuku Midoriya acquired this ability, it had grown far stronger because of One For All. So powerful that Izuku was completely incapable of controlling Black Whip's power. At this point, Black Whip's tendrils are strong enough to lay waste to a large portion of Ground Gamma.
