Red +2: While lulling its enemies with its vacant look, this wily POKéMON will use psychokinetic powers.
Yellow: Always tormented by headaches. It uses psychic powers, but it is not known if it intends to do so.
Gold: It has mystical powers but doesn't recall that it has used them. That is why it always looks puzzled.
Silver / SoulSilver: If its chronic headache peaks, it may exhibit odd powers. It seems unable to recall such an episode.
Crystal: The only time it can use its psy chic power is when its sleeping brain cells happen to wake.
Ruby: PSYDUCK uses a mysterious power. When it does so, this POKéMON generates brain waves that are supposedly only seen in sleepers. This discovery spurred controversy among scholars.
Sapphire: If it uses its mysterious power, PSYDUCK can’t remember having done so. It apparently can’t form a memory of such an event because it goes into an altered state that is much like deep sleep.
Emerald: When its headache intensifies, it starts using strange powers. However, it has no recollection of its powers, so it always looks befuddled and bewildered.
FireRed / X: It is constantly wracked by a headache. When the headache turns intense, it begins using mysterious powers.
Diamond: If its usual headache worsens, it starts exhibiting odd powers. It can’t remember doing so, however.
Pearl: It never remembers using its odd powers, so it always tilts its head in puzzlement.
Platinum +2: Overwhelmed by enigmatic abilities, it suffers a constant headache. It sometimes uses mysterious powers.
HeartGold / Y: It has mystical powers but doesn’t recall that it has used them. That is why it always looks puzzled.
Black 2 / White 2: When headaches stimulate its brain cells, which are usually inactive, it can use a mysterious power.
Omega Ruby: Psyduck uses a mysterious power. When it does so, this Pokémon generates brain waves that are supposedly only seen in sleepers. This discovery spurred controversy among scholars.
Alpha Sapphire: If it uses its mysterious power, Psyduck can’t remember having done so. It apparently can’t form a memory of such an event because it goes into an altered state that is much like deep sleep.
Sun: As a result of headaches so fierce they cause it to cry, it sometimes uses psychokinesis without meaning to.
Moon: This Pokémon is troubled by constant headaches. The more pain it’s in, the more powerful its psychokinesis becomes.
Ultra Sun: Using psychokinesis gives it a headache, so it normally passes the time spacing out and doing as little as possible.
Ultra Moon: It has been found that its brain cells are 10 times more active when Psyduck is experiencing a headache.
Let's Go Pikachu / Let's Go Eevee: Always tormented by headaches. It uses psychic powers, but whether it intends to do so is not known.
Sword: Psyduck is constantly beset by headaches. If the Pokémon lets its strange power erupt, apparently the pain subsides for a while.
Shield: As Psyduck gets stressed out, its headache gets progressively worse. It uses intense psychic energy to overwhelm those around it.
Legends: Arceus: Suffers perpetual headaches. If the agony grows too great, Psyduck's latent power erupts, contrary to Psyduck's intent. Ergo, I am exploring ways to ease the pain.
