Helioptile
The Generator Pokémon
Type: Electric/Normal
Official Registration #: 694
Entry: This foot-tall reptilian pokémon lives in the desert, where it gains energy by gathering sunlight via the electrical cells on the tips of its long, ear-like frills. Although it looks adorable with its rabbit-like frills and wide, round eyes, petting it is highly discouraged, as its dry skin is rough and, more importantly, prone to discharging of all its stored electricity directly into its hapless trainer upon physical contact.
Heliolisk
The Generator Pokémon
Type: Electric/Normal
Official Registration #: 695
Entry: The evolved form of helioptile, by exposure to sun stone. It is fairly easy to discern a heliolisk’s current emotions, based on its highly visible body language. For example, if the heliolisk’s neck frill is retracted and the heliolisk itself is resting on all fours, then it is relaxed and approachable. By contrast, if it is currently standing on its hind feet with its frill extended as it discharges several thousand volts of electricity into your body via Thunder, then there is a very good chance that it perceives you as a threat.
