Horn Cannon

Horn Cannon is the Quirk used by Pony Tsunotori.

Description
Horn Cannon allows the user to detach and launch their horns as projectiles.

Pony can fire off several horns in succession, with a new set regenerating on her head almost instantly. She possesses the ability to remotely control up to four of them as well, allowing her to change their mid-air trajectory to get around obstacles. Those horns are strong enough to restrain Mezo Shoji, who is known for his high physical strength, and thrust away Tetsutetsu Tetsutetsu, who can turn his body into metal. Her horns can carry multiple people and objects, although doing so slows their usual speed significantly.

Weaknesses
Because the horns are breakable, they require keratin ingestion in order to retain their strength. It is possible to prevent Pony from using her Quirk by just holding her horns in place.

Usage
Horn Cannon is used in long-range combat due to its projectile nature. Because of their curved shape, the horns are ideal for piercing or pinning down enemies. They can assist with mobility too, as they're large and strong enough to transport Pony or her allies around.

When controlling her floating horns, Pony gestures with her hands simulating a pair of horns on her head.

Trivia

 * This Quirk was first named in the My Hero Academia: Ultra Archive: The Official Character Guide, but was not revealed until Chapter 203.
 * Horn Cannon works similarly to Fierce Wings, as both involve detaching and remote-controlling appendages (Pony's horns and Keigo's feathers) for offensive and supporting roles.
