Joltik
The Attaching Pokémon
Type: Bug/Electric
Official Registration #: 595
Entry: A tiny, arachnid-like pokémon first discovered in the magnetic caves of Unova. Joltik’s small, furry body is incapable of generating electricity, so instead, it latches onto larger beings and picks up static electricity from them. It’s important for trainers to check themselves after leaving caves because of this. Although joltik normally latch onto pokémon, they can’t always tell the difference between pokémon and humans, and their tiny size often makes it easy to overlook them. One good way of detecting joltik is by wearing dark clothing when you travel through caves, as their neon-yellow bodies will often stand out against dark backgrounds. Another way, of course, is waiting until you’re randomly electrocuted. At that point, there’s usually a very good chance that you’re unknowingly carrying a joltik.

Galvantula
The EleSpider Pokémon
Type: Bug/Electric
Official Registration #: 596
Entry: The evolved form of joltik, by battle experience. This large, tarantula-like pokémon hunts by weaving an electrically-charged web in its domain. When prey stumbles into this web, the charge instantly paralyzes them long enough for the galvantula to crawl down, bind them in an electrically-charged cocoon, and bite them to liquefy their organs enough for later consumption. Needless to say, this is a brilliant hunting strategy in the wild. When tamed, however … not so much.
