Chimecho, the Wind Chime Pokémon. Chimecho has a voice that reverberates from deep within its body. When angry, the soundwaves can be powerful enough to blow opponents away.

Chimecho seems to be a filler Pokemon. When it was introduced in Gen III, it had no evolutionary relatives, but later in Gen IV, a baby version of it was introduced. In fact, its index number (used for the game code) is the last in Gen III (after Deoxys), as if it was added as an afterthought.
In the anime, James had a Chimecho. Its chime is said to be very sweet and soothing. After the Team Rocket motto, Jessie’s Wobbuffet would say “Wobbuffet!” and Chimecho would follow that by saying “Chime chime”. James had to leave it behind however, when it was sick (apparently the Pokemon center machine was broken or something? haha)
Stat-wise, it has decent Sp Attack, but it still pales in comparison to many other Psychic types like Gardevoir or Alakazam. Chimecho does get the ability Levitate though, so it’s immune to Ground moves.
