I'm not sure if we should make a new thread for it, but here's a few I can remember off the top of my head and their highlights (starting with the obvious one):
HypnoRuby/Sapphire Pokedex said:
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.
FireRed Pokedex said: It carries a pendulum-like device. There once was an incident in which it took away a child it hypnotized.
JynxRuby/Sapphire Pokedex said:
Jynx walks rhythmically, swaying and shaking its hips as if it were dancing. Its motions are so bouncingly alluring, people seeing it are compelled to shake their hips without giving any thought to what they are doing.
ChandelureBlack Pokedex said:
It absorbs a spirit, which it then burns. By waving the flames on its arms, it puts its foes into a hypnotic trance.
GothoritaBlack Pokedex said:
They use hypnosis to control people and Pokémon. Tales of Gothorita leading people astray are told in every corner.
Black/White 2 Pokedex said:
According to many old tales, it creates friends for itself by controlling sleeping children on starry nights.
AegislashX Pokedex said:
Generations of kings were attended by these Pokémon, which used their spectral power to manipulate and control people and Pokémon.
InkayX Pokedex said:
Opponents who stare at the flashing of the light-emitting spots on its body become dazed and lose their will to fight.
MalamarX Pokedex said:
It wields the most compelling hypnotic powers of any Pokémon, and it forces others to do whatever it wants.
Y Pokedex said:
It lures prey close with hypnotic motions, then wraps its tentacles around it before finishing it off with digestive fluids.
SpritzeeX Pokedex said:
It emits a scent that enraptures those who smell it. This fragrance changes depending on what it has eaten.
Alteria may count
Ruby Pokedex said:
Altaria dances and wheels through the sky among billowing, cotton-like clouds. By singing melodies in its crystal-clear voice, this Pokémon makes its listeners experience dreamy wonderment.
Feel free to search for more.
