Moistquito, the Drainage Pokemon Moistquito gorge on moisture in all its forms. It uses its long nozzle mouth to steal from people's drinks. A stream of water runs from Moistquito's mouth to its tank. It can pressurize the stream to create legs.
Types: Bug / Water Ability: Drain Tank — Moistquito is immune to draining effects, and its own at 50% more powerful. Hidden Ability: Water Absorb Signature Move: Get a Buzz — Bug | Special | 60BP | Up to half the damage dealt gets restored as HP. If the user's HP is already full, it lowers the target's Special Defense one stage instead.
Despite its small size, Moistquito is a fully evolved Pokemon, chewing up foes with double boosted drain moves. It wouldn't have a great HP stat to cap out how much it heals, but doesn't mind being at full HP, turning its signature ability into a better Bug Buzz while it's there. Just be careful of chip damage, healing 10 damage is still healing.
