Remoraid

Remoraid, known in Japanese as テッポウオ (Teppouo), is a Water-type Pokémon introduced in Generation II. It is a small, light blue, fish-like Pokémon. Remoraid is well known for its ability to shoot jets of water out of its mouth with incredible accuracy and distance, earning it the nickname "the sniper of the seas." Its body features distinct markings resembling a revolver, with its back stripes resembling the barrel and its pelvic fin resembling the trigger. Remoraid tends to live in the sea and often attaches to the underside of Mantine, feeding on scraps and parasites. As evolution draws near, it travels upstream to rivers. Additionally, having Remoraid in the party while leveling up a Mantyke will cause Mantyke to evolve into Mantine. Remoraid evolves into Octillery starting at level 25.
