Zubats – Pokémon
Another cave-loving creature, the Zubat is just a massive pain in the neck. It’s already dark in the caves, so you’re dealing with that, but the Zubat uses status-effect abilities that were apparently concocted by the Pokémon archdemons. Confuse Ray and Supersonic means your Pokémon will occasionally attack themselves instead of the dumb Zubat for a series of turns, making these some of the most teeth-grinding enemies in the games.
