Unown (アンノーン, Annōn, Unknown in original Japanese language versions) is a fictional swarming creature in the Pokémon media franchise.
In Super Smash Bros. Melee
As a Poké Ball Pokémon
The Unown make their only appearance in Melee and appear out of Poké Balls. Unown's attack is Hidden Power, similar to Onix and Beedrill's attacks in Super Smash Bros. When Unown is summoned, a random letter of Unown flies off the screen. A group of Unown will then begin flying from one side of the screen to the opposite side. Any character that makes contact with the swarm of Unowns will take damage. The character that made contact with the Unowns will also be forced to the top of the screen. The character even has a chance of dying at low percentages. Unown's attack does not harm the summoner. Unown's role is very similar to Beedrill's in Super Smash Bros.
As a trophy
26 of the 28 varieties (all except for the Question Mark and the Exclamation Point) of Unown feature together as a collectible trophy, which is unlocked by amassing a combined total of over 16,503 feet with all the characters in the Home Run Contest. It reads as follows:
These symbol Pokémon resemble ancient hieroglyphics found on rocks, a resemblance that's said to be more than superficial. Quite a few different shapes of Unown have been confirmed, and it's believed that each type has unique abilities. These enigmatic Pokémon can be found in the Ruins of Alph.
As an element of Kanto Skies: Poké Floats
In the stage Kanto Skies: Poké Floats, Unown fly past at moderately high speed. They act as platforms and the players can fall through them. They travel in different directions.
