Wailord

Wailord's size does not translate into usefulness, especially in a metagame where Pokemon such as Alomomola and Ludicolo are so common. Its main selling point is the deadly Water Spout, which pairs with Choice Specs to become a weapon that crushes anything that doesn't resist it. While Water isn't the best type to spam with the prevalence of Water-immune and -resistant Pokemon such as Seismitoad and Roselia, Wailord unfortunately has average at best power with its coverage moves. Despite its size, Wailord is not difficult to wear down, as its high HP is mitigated by its low defenses. Low Speed becomes the final nail in the coffin, as Wailord cannot outspeed most offensive teams without a lot of support.
