Control Horn

Control Horn is the unnamed Quirk used by Cow Cowboy.

Description
Control Horn allows the user to mind control cows.

Cow Cowboy is seen controlling hundreds of them at a time as he was threatening to stampede a whole province of Japan if his demands were not met.

Weaknesses
It appears that Cow Cowboy needs both horns intact for his Quirk to work, as when All Might chops one off, it stopped working.
