Helioptile

They make their home in deserts. They can generate their energy from basking in the sun, so eating food is not a requirement.

The frills on either side of its head have cells that generate electricity when exposed to sunlight.

When spread, the frills on its head act like solar panels, generating the power behind this Pokémon’s electric moves.

The sun powers this Pokémon’s electricity generation. Interruption of that process stresses Helioptile to the point of weakness.
