Wailord

Wailord is one of the most underrated threats in the UU metagame. At a glance, it seems to have lackluster base defenses, even with its enormous base 170 HP, and only passable base offenses, which are further hindered by Wailord's low base Speed stat of 60. However, if you take a closer look, it becomes clear that Wailord does actually have a niche in the UU metagame; its access to Water Spout, a powerful 150 Base Power move that is dependent on the user's HP at the time of use, allows Wailord to act as a destructive special attacker. By simply spamming Water Spout, Wailord can become a dangerous offensive threat to any team not prepared for it.
