Wailmer is technically a pre-evolution of Wailord, but it holds its own in formats where Eviolite is allowed. Only weak to Electric and Grass. Flexible enough to run physical or special sets. Part of the Gen 3 roster.

The stat line revolves around HP. Percentage recovery gets extra mileage here. Attack backs it up, though Defense doesn't pull its weight. Worth 1 HP EV on a standard growth curve to max out.

  • At 400 BST, Wailmer is firmly in pre-evolution territory. Evolve it into Wailord before bringing it to any serious fight.

  • Wailmer's biggest threats include Manectric (Electric) and Venusaur (Grass), all carrying super-effective STAB moves. Only 2 weaknesses means fewer dedicated counters to worry about.

  • Wailmer evolves into Wailord at level 40. Wailmer is the base form of this evolutionary line.

  • Water Veil is the go-to ability for Wailmer. It prevents burns. Its hidden ability Pressure can work in specific setups. Oblivious is the other option — pick based on what your team needs.

  • Wailmer is a mixed attacker — base 70 Attack and 70 Sp. Atk. Enough bulk to take a hit or two, too. But the speed tells the real story — at base 60 Speed, it won't be moving first often.

  • Wailmer appears in 14 games, including Ruby & Sapphire, FireRed & LeafGreen, and Emerald.

Debuting in Ruby & Sapphire, Wailmer appears in 14 games across 7 generations. A reliable presence in a solid number of games, typically found through catching or hatching as a base form.
