"Hypno holds a pendulum in its hand. The arching movement and glitter of the pendulum lull the foe into a deep state of hypnosis. While this Pokémon searches for prey, it polishes the pendulum."
Hypno is an interesting Pokemon in not just its use of Psychic powers, but in that it uses a man-made object to help focus them. In the anime, a Hypno was used to help save a city that a Drowzee accidentally made sleepwalk. And Hypno has been used by many a trainer in the video games.
Hypno's Basic Attacks are Confusion or Zen Headbutt, while its Special Attacks are Psyshock, Shadow Ball, or Psychic.
