Name Item Nature

Bulky Water

Leftovers Modest / Bold
Moveset EVs
~ Surf
~ Ice Beam
~ Toxic
~ Rest
252 Def / 4 SpA / 252 SpD

The standard Surf / Ice Beam / Rest / filler set for bulky waters. It can work, but its defenses are a bit too low to pull this off.

Name Item Ability Nature

Exploding Whale

Leftovers Water Veil Brave / Quiet
Moveset EVs
~ Selfdestruct
~ Hidden Power Ghost
~ Surf
~ Ice Beam / Earthquake
4 Atk / 252 Def / 252 SpD

The last move is really just a filler for lack of better options. Hidden Power Ghost is for Ghosts, while Surf takes out physical walls. This allows you to Selfdestruct for neutral damage on something, most likely killing it, which is really the only way Wailord is killing anything in OU, if you really want to use it there. It's also probably the only way you're killing anything in UU, to be honest. Hidden Power Ghost is primarily Gengar in OU, but it is still useful in UU / BL, because it hits that Grumpig or Hypno that thinks it can come in on you and wall your Special hits (it 3HKOs Grumpig). Alternately, you could Surf Grumpig as it comes in, and then Hidden Power Ghost as it Trickbands.

Name Item Nature

Water Spout

Leftovers Modest / Quiet
Moveset EVs
~ Water Spout
~ Ice Beam / Body Slam
~ Sleep Talk
~ Rest
252 Def / 4 SpA / 252 SpD

Have fun with this if you wish. Rest / Sleep Talk is to keep Wailord's HP as near to max as possible, Water Spouting off its decent 90 Special Attack. Ice Beam hits Grass Pokémon harder than max power Water Spout, but Body Slam helps Paralyze, which Water Spout Wailord really needs to hit stuff at full power.

Name Item Nature

Curser

Leftovers Brave
Moveset EVs
~ Curse
~ Earthquake
~ Ice Beam / Surf
~ Rest / Selfdestruct
68 Atk / 188 Def / 252 SpD

Curse reduces the amount of damage being done to Wailord, while you pound the enemy with Earthquakes from its 90 base Attack.

Other Options

It can Amnesia to try to survive special attacks. Wailord can use Roar to phaze stuff, but there is little need for that in much of NU.

EVs

Never give Wailord HP EVs, it's one of the few Pokémon where it's better to just split those EVs into both defenses. Instead, fill up its PATHETIC defense stats first and then worry about Special Attack, or even Attack if you are using Earthquake.

Opinion

Wailord is an underpowered Pokémon compared to other Water-types and should not be used outside of UU or NU other than for novelty.

Counters

For the Surf / Ice Beam Bulky water set, most other waters can beat you one on one, or stall you at the least. Qwilfish and Tentacruel are both resistant to your offense and immune to Toxic, and can set up either Spikes or Swords Dance on you, so watch out for those two little buggers. Quick electrics such as Electrode or Raichu can put the hurting on Wailord too, but if it's a Cursing version they should be wary of Earthquakes. Any sweeper that can dish out damage fast and hard can deal some good damage to Wailord, such as Normal Choice Banders, but Flyers should beware of Ice Beam. Basically try to hit it with boosted or super-effective moves and you will dispose of it quickly enough. Its defenses are just too bad to make it take a lot of good hits. Anything that calls itself a Special sponge will be easily able to wall Wailord's offensive possibilities, ensuring it usually cannot get past things like Hypno, Grumpig, or Lanturn either.
