>>14291667>Implying abilities, especially those of legendary Pokémon tied into the story, are based on competitive viability and not on the design of the Pokémon itself.Why do Joltik and Galvantula have Unnerve? Arachnophobia is common. Spiders are unnerve. It's a shitty ability, but it's great for the design of the Pokémon.
