Red/Blue:When it locks eyes with an enemy, it will use a mix of PSI moves such as Hypnosis and Confusion.
Yellow:Avoid eye contact if you come across one. It will try to put you to sleep by using its pendulum.
Stadium:If you lock eyes with it, it will try to hypnotize you. It is best to close your eyes quickly before you get hypnotized.
Gold:When it is very hungry, it puts humans it meets to sleep, then it feasts on their dreams.
Silver:Always holding a pendulum that it rocks at a steady rhythm, it causes drowsiness in anyone nearby.
Crystal:The longer it swings its pendulum, the longer the effects of its hypnosis last.
Ruby/Sapphire:Hypno holds a pendulum in its hand. The arcing 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.
Emerald:The arcing movement and glitter of the pendulum in a Hypno's hand lull the foe into deep hypnosis. While searching for prey, it polishes the pendulum.
FireRed:It carries a pendulum-like device. There once was an incident in which it took away a child it hypnotized.
(Notice I underlined once because this is the case, it states "There once was an incident". Thanks to this one entree and Creepy Pasta Hypno is now ridiculed, hated and called a Pedo. This is very frustrating to a Hypno fan. I'm constantly having to defend him and this is all thanks to Creepy Pasta making a twist off of one Pokedex entree.. :/)
