Octillery

As a Water-type Pokemon, Octillery is mostly outclassed by Pokemon such as Gorebyss and Seismitoad, and is therefore very rarely seen in the tier. Fortunately, it does have great offenses backed by a powerful STAB Hydro Pump , meaning that it can do huge damage to most opponents, and a wide coverage movepool, meaning that would-be checks need to think twice before switching in; unlike other Water-types, Octillery can hit Water-, Grass-, and Dragon-types for massive damage with the appropriate coverage move. However, it isn't particularly bulky and its Speed is disappointingly low, meaning it will always have to take a hit before being able to strike back.
