Unown

Unown is a Psychic-type Pokémon that first appeared in Pokémon Gold and Silver. It is unique for having twenty-eight different variations, the twenty-six letters of the English alphabet plus the question and exclamation marks. In Super Smash Bros. Melee, it can be spawned from a Poké Ball and attacks by using Take Down (interestingly enough, Unown cannot learn this move in the Pokémon series); a single Unown is spawned and flies off-screen, dealing moderate knockback and damage if it hits an opponent. After it flies away, a swarm of Unown soon flies diagonally across the screen, juggling opponents who come into contact with them.
