Wailmer Line

Morphs [Oak Catalog #]

  • Wailmer [#320]

Wailmer are large and spherical in shape, with much greater buoyancy than Wailord. Their tops are dark blue and their bottoms are a cream color, and they are situated with two fins and no tail.

  • Wailord [#321]

Wailord are oval-shaped and are lighter shades of blue. They have four fins instead of two and are the largest Pokémon in existence. They often look like one really big tail.

Notable Biology

Wailmer often find it difficult to swim and dive as a result of their shape, especially in their early years, and so are more commonly found than Wailord. Both Wailmer and Wailord are situated with baleen hairs instead of teeth. They must eat a lot of very small but very abundant water-type Pokémon such as Luvdisc in order to nourish such large bodies. Wailmer and Wailord are also situated with surprisingly hollow and light bones, possibly a result of their environment.

Wailord are even larger than Wailmer, recorded as the longest Pokémon in recorded history from tip to tail, and largest from belly to blowhole. Wailord are more oval-shaped than their pre-evolution, and are situated for better streamlining for swimming and migration. Despite their incredibly large size, they weigh less than a half-ton, as the tenth-heaviest Pokémon; a very surprising feat for a Pokémon of its size. Some have speculated that they have helium sacs in their bodies that make this possible, but no definitive answer has been found yet. Others have speculated that the official weight of 877.4 lbs. is a typo, and should read 8,774.6 lbs, or 4 1/3 tons, a much more reasonable weight for Wailord.

Unlike many other Water-type Pokémon, Wailmer and Wailord both mainly breathe air. Their noses, as such, are situated on top of their heads for easier breathing. They are capable of holding their breath for over 10 hours.


Both Wailmer and Wailord often migrate to cool temperatures when their current habitat becomes too warm. Most Wailmer are found closer to the shallows than Wailord, and thus are more easily captured on beaches by children. They are substantially more common than Wailord, who usually prefer to swim in tight groups far away from human activity. A few Wailmer even decide to get closer to the tropical region of Hoenn, speculated to be them attempting to prove themselves to overprotective Wailord parents.

Most trainers get a Wailord through training and evolving a Wailmer, though there have been several occasions where a wild Wailord was caught instead. Wailord prefer to live deeper in the sea, often closer to the arctic circles, and often very far from large bodies of land. On occasion, they will chase down rebellious Wailmer who come closer to Hoenn, but rarely decide to get closer than route 129. They are occasionally seen off the coast of Sinnoh, and are uncommon but far from unheard of in Unova's Undella Bay. Wailord are very capable divers, with the furthest recorded dive being almost 12,000 feet.


Wailmer and Wailord are both situated with baleen hair in the place of teeth, though when viewed from afar look a lot like teeth. Despite that, their diet is mainly carnivorous, often consuming large quantities of Luvdisc (oftentimes the only Pokémon thin enough to fit through the hairs). However, they are capable of eating regular berries if they are in thin slices. The same goes for Poke Blocks and Poffins.


Wailmer and Wailord are not very dangerous in the conventional sense, as they do not like to attack anything substantially smaller than they are. However, many lost Wailmer have been known to confuse large boats as a Wailord, and attempting to group with the boat as a podmate has resulted in several cases of boat crashes and casualties, occasionally opening a gateway for Sharpedo to gather. Luckily, they can easily recognize a trainer riding on a Pokémon instead, so it is advised to ride your Pokémon when in Wailmer territory.

Attempting to catch wild Wailord is only safely capable if you are lucky enough to find a stray off the east coast of Hoenn or even rarer through fishing in Sinnoh or Unova. Finding them without diving is not common, though actual attempts to tail a diving Wailord are not recommended under any circumstance. Wailord are very fast, and can dive so deep that the pressure will not only cause a Dive bubble to pop, but may even result in death.

Courting and Childrearing

Wailmer and Wailord are both in the Field Egg Group. Most Wailmer do not breed, but they will if in captivity. Mating season occurs only once every three years. When it comes time to breed, both male and female Wailord in a pod breach out into the sky as high as they can, to see if there are any other pods nearby to avoid inbreeding. If there is a pod nearby, the pods break up and reorganize themselves differently after they have all chosen a mate.

The pod stays together guarding the eggs for a very long time, and are very defensive over their young. Once the first egg hatches, the newly-made sub-pods say their goodbyes and go their separate ways. The new alpha family teaches their song to keep the families together during migration.

In captivity, and especially when Trained, some Wailord have been forced to breed with other species, with most cases of forced breeding involving, for some odd reason, Skitty. Due to their large size, especially when compared to Skitty, this is not recommended.

Social Structure

Wailord usually live in a system of pods and sub-pods. A main pod of Wailord is a system of families, often with one Alpha family leading the pod when it comes time to migrate. Outside of migration, Wailord usually live in sub-pods of two nuclear families consisting of parents and child Wailmer, ranging from 1-4 brothers and sisters per family. Oftentimes a specific Wailord Song is used to call the Sub-pods together for migration, each song different per each pod.

During mating season, mega-pods are formed, where up to three pods come together to mate with different Wailord. Nuclear families rarely stay together for more than 3 years, choosing a new mate come mating season. However, if a Wailord grows old enough to see their grandchildren, they will often take over for dead or missing parents and care for the Wailmer on their own.

None of these groups involve Skitty.
