Horn Attack

Use Your Head is good and all, but sometimes using blunt force is not effective. Instead, a sharp horn on the head can be more useful. Also included are horns that can shoot projectiles or beams.

Weaponized Headgear often have spikes to be used in this regard.

Subtrope of Natural Weapon. See also Rhino Rampage, A Load of Bull, and Horned Humanoid. Can result in being Impaled With Extreme Prejudice.

 * In a TV commercial for Mountain Dew, a GenXer goes up against a ram in a ramming contest over a bottle of Dew. The GenXer wins.

Anime and Manga

 * In the third One Piece movie, the villain goes on One Winged Angel after eating some magical golden horns and transform in a giant furry behemoth with large golden antlers. Not only he's strong enough to cause an earthquake when he headbutts the ground, but he can also heat them up. In the main series, Chopper's strongest form is the "Horn Point".
 * Also Magellan appears to be a Horned Humanoid, but the "horns" are actually detachable and he can wear them on his hands as weapons.
 * Subversion: Duval's pet Bison, Motobaro tries to ram Luffy as Duval gushes about how his "Heart-Crushing Horns" are unstoppable and capable of bringing down walls and dams.... then when the two impact, we clearly see that Motobaro's horns are far above Luffy. Chopper even lampshades this.
 * In Tiger and Bunny, Rock Bison has a large pair of horns on his Powered Armor. Subverted in that when he tries to use them to stop a getaway car, the horns get stuck and the crooks get away.
 * This is how Chirin actually kills the evil wolf at the end of Chirin no Suzu (he is now a sinister-looking ram).

Multiple Media

 * Bionicle's Kane-Ra bull and the Mix and Match Critter Rahi Nui, which has the head of a Kane-Ra, usually use this strategy. The Rahi Nui, at its first appearance, was in fact defeated by letting it drive its horns into a rock wall with so much force, it couldn't pull itself out. Strangely, the actual Kane-Ra toy is an aversion, as it has a jaw-snapping attack, and the horns are just decoration.

Real Life

 * The sheer diversity of horned/antlered animals today and in Earth's past is a testament to the ostensible Truth in Television of this trope. However most examples from Nature tend to be subversions: horns are primarily for display of fitness. Only when contenders for mating rights/territory/food are evenly matched are they used aggressively, though most of the resulting scraps are akin to wrestling matches. Things have Gone Horribly Wrong though. This doesn't stop horns being used as offensive weapons among species, especially when prey defend themselves against predators, though unlike the fictional examples it isn't their main function.
