Static
The Pokémon is charged with static electricity, so contact with it may cause paralysis.
Limber
Its limber body protects the Pokémon from paralysis.
Thanks to bacteria that lived in the mud flats with it, this Pokémon developed the organs it uses to generate electricity.
For some reason, this Pokémon smiles slightly when it emits a strong electric current from the yellow markings on its body.
