Banette

Banette (Japanese: ジュペッタ Juppeta) is a Ghost-type Pokémon introduced in Generation III. It is said to be a plush doll that was thrown away and became possessed by a powerful grudge, giving it life. Banette resembles a dark gray doll with three spikes on its head, a zigzagging ribbon trailing off the back, and a yellow zipper for a mouth. It generates curse energy by sticking pins into its own body, which it uses to attack opponents. Banette is often found in garbage dumps and dark alleys, where it seeks revenge on the child who discarded it. When Banette Mega Evolves into Mega Banette, it gains more zippers on its body, revealing purple claws and parts of its body. Mega Banette's curse power is amplified so much that it can't help cursing its own trainer.
