Chimecho-Mega

Ruby: CHIMECHO makes its cries echo inside its hollow body. When this POKéMON becomes enraged, its cries result in ultrasonic waves that have the power to knock foes flying.

Sapphire: In high winds, CHIMECHO cries as it hangs from a tree branch or the eaves of a building using a suction cup on its head. This POKéMON plucks berries with its long tail and eats them.

Emerald: They fly about very actively when the hot season arrives. They communicate among themselves using seven different and distinguishing cries.

FireRed / LeafGreen: It travels by riding on winds. It cleverly uses its long tail to pluck nuts and berries, which it loves to eat.

Diamond: To knock foes flying, it makes the air shudder with its cries. It converses using seven cries.

Pearl / Y: Emitting ultrasonic cries, it floats on winds to travel great distances.

Platinum +4: Its cries echo inside its hollow body to emerge as beautiful notes for startling and repelling foes.

HeartGold +2: It uses the sucker on its head to hang from a tree or from eaves. It can produce seven different tones.

Omega Ruby: Chimecho makes its cries echo inside its hollow body. When this Pokémon becomes enraged, its cries result in ultrasonic waves that have the power to knock foes flying.

Alpha Sapphire: In high winds, Chimecho cries as it hangs from a tree branch or the eaves of a building using a suction cup on its head. This Pokémon plucks berries with its long tail and eats them.

Legends: Arceus: Can emit waves of air powerful enough to knock out prey taller than itself. I hypothesize that it amplifies the faint sound of wind within its body.
