Unihorn was a Demon-level Mysterious Being fighting under the Monster Association banner. Dispatched by Gyoro Gyoro to hunt down an intruder alongside Super Mouse and Showerhead, the boastful monster met a swift end at the hands of Overgrown Rover.
This creature wore a roughly humanoid shape crowned by a single massive horn jutting from its brow. Eyes studded its body all over, and its face was a jumble of crooked teeth and misaligned jaws with neither nose nor ears to speak of. When Unihorn shifted into combat mode, the whole body stretched into a long lance, the mouth sliding to the middle of the shaft while the scattered eyes still lined its length.
Unihorn carried himself with loud self-assurance, forever crowing that his horn was the toughest anywhere and simply could not be broken. That bravado aside, he stood apart from many of his peers in one respect: he had no trouble teaming up with fellow monsters to gang up on a shared foe.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
His rank as a Demon-level threat marked him as genuinely dangerous, and he weathered a blow from a rapidly evolving Garou without being finished. Great strength and startling speed were his trademarks, the latter letting him whirl his frame into a spinning blade like a giant buzzsaw. His prized horn backed up the durability boasts up to a point, surviving a kick that cratered a wall. His signature trick was the Killer Form, in which he became a honed spear that traded arms and legs for extended reach. Super Mouse and Showerhead then launched him in the combination assault known as the Demon Trinity's Bursting Speed Thrust. Garou shrugged the strike off, having already seen something similar from Stinger, and the errant attack pushed Overgrown Rover into treating everyone present as an enemy. Rover flung Unihorn back, shattered the supposedly unbreakable horn, and vaporized him along with his two partners.
