The existence of Metaloom is uncommon, and its behavior is understandably confusing. Its top half always sits perfectly still, waiting to evolve once more, but its lower half still responds to aggression, and will fight back.

When it's time to rest and evolve, Metaish buries itself in the ground and hardens to become like steel for over a week. Trainers that encounter Metaish will often stub their toe or trip over them due to them resembling a lump of moss.

The tentacles around Tanling's face ensure that anything it catches doesn't get away. These tentacles regenerate very quickly if they are cut off, preventing its face from being exposed.

The fluid in Weeba's body allows its String Shot to be used for communication over long distances. Unfortunately, it often runs out of string before it can escape from a chasing Pokémon.

At first glance, a Weeary's fluff looks soft and harmless. However, touching it will result in your hand being covered in a sticky, rubbery glue that can stick your fingers together for up to a week if untreated.

Weeish is a worryingly common fusion that is undesirable to farmers. It will plant itself in crop fields, eating and sucking out all the nutrients and minerals in the soil until it is unsuitable for growing any sort of plant inside of it.

Weenat's shaggy fur and powder-covered body irritates its nose, causing it to sneeze and release its powder in bursts. Some Trainers find it very endearing and adorable, but will suffer the consequences when they observe up close.

Weeth will often be distracted by simple things, making it a Pokémon only really suitable as a house pet. Sometimes, it will make a ball out of its own String Shot and play with it like any domestic cat Pokémon.

Kakrak curls its legs underneath its belly when hanging from a web to resemble a helpless, unfused Kakuna. As small as it is, it still attempts to latch onto and poison any Pokémon that attacks it.

Beegey's black and yellow wing colors give any predatory Pokémon enough of a warning of its deadly sting. All 6 of its claws combined have enough poison inside of them to put down a Wailord.

The honey Beegeot produces from its long strand of hair is deeply rich, non-toxic and very versatile. It makes poor tasting foods delicious, works as a hair gel, and in thicker doses, works like superglue.

Instead of eating bugs, Pidfree relies on eating flower nectar and dew, which is more difficult to come by given the increased size and body weight. It requires at least 1 pound of nectar and dew every day to fill Pidfree's stomach.

Despite it resembling an immature Pidgeotto, Pidotto is far from it. Its bigger body allows it to glide through deep forests and hunt prey at tripled speeds, but being bigger means that it requires much more food than a normal Pidgey.

Pidchu is easily swept away by strong wind as it flies, which often frustrates it. Pidchu has a short temper and will split trees in half with a lightning bolt, leaving it dizzy and exhausted.

Its head feathers don't shine as brilliantly as an ordinary Pidgeot, making it more vulnerable to being rejected by a potential mate. Despite this setback, it still retains its incredible feats of speed and strength.

Pidkern's way of hunting for prey is different based on their nature. While some Pidkern rely on the wind to float towards and catch prey as it passes, some will instead bury themselves in the dirt and eat whatever is living inside it.

Wild Pidbull don't hesitate to tear apart the bases of trees in order to find small, edible Pokémon. However, when domesticated, Pidbull are surprisingly patient and tolerant, and have a sharp memory.

Pidrow is self-aware of how odd its long neck and tiny head appear to others, but more often than not, other Pidgey admire it. They even rely on Pidrow to use its long neck to dig for Bug-type Pokémon from the ground.

Pidchu's appearance is misleading when viewed from below as it flies. Some claim that when struck by lightning, it discharges powerful electric energy in return, often scorching the ground beneath it.

Pidshrew's wings have scales along the back that allow it to negate electricity from wild Pokémon while it flies. Pidshrew can be seen bathing itself in sand and mud before blowing it off by flying around at top speeds of 100 mph.

When two Pidran confront each other over a single mate, they begin to scream at each other, each attempting to be louder than the other. These fights tend to last for up to two hours, and by then, the mate they were fighting for will have left.

Pidran's impeccable hearing allows it to hear bug Pokémon crawling 10 feet underneath the ground. Several Trainers have had to be rescued from falling into one of these holes created and left by Pidran.

Pidpix is a very sought-after wild fusion for beautiful- and rare-pet owners. Its wings and tails are soft as silk, and it only become more valuable as it evolves.

Pidkoth uses its long, flexible arms to reach inside trees and grab its prey. It cannot fly well, which results in most Pidkoth being an easy target for even the weakest of predators.

Pidnx uses its tail to lure out bug Pokémon, simulating a ray of sunlight for it to follow. It stuns bigger bug Pokémon by whipping its tail at them, paralyzing their bodies from the outside.

The extra bundle of feathers covering Pidish's shoulders give it extra warmth, and allow it to withstand colder environments. Despite this, it still chooses to remain in warm places with sunlight anyway.

Pidsis's squishy body allows it to squeeze inside trees and eat any and all bug Pokémon it finds. It is able to remember every feasting spot by leaving a small portion of its body nearby.

Pidbat screeches into the holes of trees and cave walls, causing small Pokémon to come out, stumbling and confused. There is no set schedule for when Pidbats are awake or asleep, as they only rest when they need to.

Pidnat's eyes can spot even the smallest bug Pokémon in the smallest crack of a tree trunk. It rubs its body against trees to release powder that causes bug Pokémon to crawl out paralyzed or poisoned.

Pidth makes its nest with stolen money or belongings between the sticks and twigs of its base. If it finds a shinier nest from another Pidth, it will attempt to fight for ownership of it.

Even though their bodies are not able to fly well, Piduck still tries to glide across trees for its prey. Even after hitting its head several times on the way down, Piduck will still climb back up and try again.

Pidwag's existence on land and sea led to its unique method of catching prey that is unlike most Pokémon's. One Pidwag scares bug Pokémon into falling into nearby bodies of water for other Pidwag in its pod to consume.

Pidpoke is able to sense many bug Pokémon in a single area, but its hunting ability is very unorthodox. It sits near the general area with its mouth wide open for up to 8 hours, hoping its prey will happen to crawl inside.

Despite its slow movement, Piduk is an exceptional hunter. It lays up against trees, blending into the bark, and strikes unsuspecting prey that stops to rest on it.

Hootling's singing is helpful for making Trainers fall asleep at night. Its singing is so effective that it frequently puts itself to sleep.

Pidgeuna struggles to use its wings due to being in a cocoon state. Instead, it simply uses String Shot to swing from one tree to another, hoping to eat just enough bug Pokémon to get by and evolve.

Pidgegey instinctively catches and consumes more prey than its body can handle. However, in an act of kindness, it shares its meals with other Pidgey in the group.

Pidgegeot is one evolution away from perfection in every remarkable talent of the Pidgey line. Unfortunately, its lack of a long, flowing lock of hair gives it a disadvantage at looking intimidating to rivaling Pidgeots.

The crest of hair on Pidgerow's head gives it a sense of authority among other Spearow. Sometimes, it will exude so much authority that a flock of Spearow might consider Pidgerow greater than their leading Fearow.

The body shape and feather colors of Pidgerow are enough to confuse both sides of its fused cousins. The side that Pidgerow falls with depends on which half of its mind is greater, which changes frequently.

Pidgechu flies high enough to be inside the clouds while charging up electricity, and creates a raging lightning storm as a result. Only a few Trainers have ever witnessed a Pidgechu do this.

When a Pidgerina isn't digging for some small, juicy Pokémon, it sits and watches Pidgerino brawls to admire a potential partner. It relies on Pidgerinos to fly up into the trees to get more food for them due to Pidgerina's smaller wings.

Pidgerino brawls happen in groups of 5 to 10 to decide the leader. The fights are so intense and violent that it attracts any Pidgerina that hears their battle cries and clashing of horns and talons.

Pidgesis hierarchy is based on the length of its feather crest. Because of this status check, the most dominant Pidgesis is unable to split or leave behind any of its body to remember feeding spots, as its feathers will shrink with it.

Pidgeish is a lot more mobile than it appears. Its light body weight and small size mean a single huge flap of its wings can send it soaring a mile away.

When Pidgeoom sees its favorite food, its funky, mind-numbing drool comes out at a rapid pace. The only Trainers who manage to withstand owning a Pidgeoom tend to feed it a food it doesn't love but still tolerates.

Pidgenat flaps its wings to blow its powder all over the forest trees and ground. It can then sense places where the powder is disturbed to attack and consume small Pokémon that are affected by it.

Pidgeduck's somewhat clear head allows it to see Pokémon hiding inside trees. However, it usually ends up misjudging and gets attacked by something far bigger and more dangerous than it can handle.

Pidgekey's air control in combat is outstanding compared to other winged Pokémon. It is able to remain in the air while punching, kicking, and even being upside down.

Pidgeape's flight and fight technique is comparable to Hawlucha, with a focus on air-based combat. It is able to deliver steel-bending blows even without a ground to support its weight.

Specialized Trainers often choose Pidgelithe to scout for rare Pokémon and materials. Its enhanced sense of smell and far-reaching cry allow it to find anything it's commanded to and call for help up to 10 miles away.

When cornered by a dangerous Pokémon, Pidgewag will spin its body around rapidly with its wings, making the spiral on its chest appear to spin. Most Pokémon that see it will feel their weight shift to the side without any contact.

The wings and glistening mustache of Pidgebra give it telekinetic powers that allow it to avoid attacks automatically in the air. It has been observed that Pidgebra has made Kadabras display an emotion researchers dub as mustache envy.

Pidgesprout spends several hours doing nothing but sucking up and melting dirt in its mouth, hoping it will consume any buried bug Pokémon in the process. 90% of its diet ends up being just dirt.

Pidgeler's wings are just about strong enough to keep it airborne. Because of this, it is able to drop down onto big rocks to break them open and eat any minerals and bug Pokémon it finds hiding inside.

Somewhat smarter than normal, Pidgepoke can see where a bug Pokémon may end up in its reach and prepares to strike for that moment. It usually miscalculates and misses its mark 75% of the time.

Pidgeel's feathers merge into its skin to make it furry, warm, and waterproof. This change in its body allows it to dive into cold water to scoop up fish Pokémon, and even rest on top of the water.

Despite its lack of wings, Pidpie is capable of amazing flight. Its sticky, yet feathery body allows it to fall hundreds of feet from off of trees unharmed to feast on nectar on the surface, and floats back up from the slightest breeze.

Because of its curved-out body shape, Pidpod will often fly a bit too high for its comfort. To counter this, it hardens its body, giving them enough weight to come back down and not float off into space.

Other bird Pokémon are easily frightened by Pidfree due to its doubled pair of wings that give it lots of air control. However, its intimidation factor is what allows Pidfree to protect the Caterpie and Metapod it has bonded with.

In an unlikely situation where Pidgey can't agree on their share of prey, this Pokémon steps in to settle the dispute. Its leadership resembles that of a seasoned flock leader, ensuring order among its group.

A Pidrow was sighted invading a flock of 30 Spearow and Fearow on its own. By the end of the encounter, just 5 minutes later, the Pidrow had become the flock leader.

Pidrow doesn't attack unless provoked. All Pidgey and Spearow fear Pidrow from appearance and demeanor alone and will give up their meals, hoping they will be spared from its razor-sharp talons and beak.

A swarm of Ratpod can't move, and rely on Raticate to carry them from one place to another. Its singular tooth allows it to nibble on and break tree nuts, and break out from another Pokémon that tries to eat them.

Despite needing rest to fully evolve, Ratuna prefers to squeal and hiss for several hours, channeling the rage required for it to evolve. Its cries can be heard from up to 5 miles away, making potential predators dizzy in close proximity.

Ratdrill will always eject its drill hands to grow new ones when they get worn out. Unsuspecting Pokémon will try eating these discarded drills, only to find they are still packed with excess poison that can sit in their stomachs for up to a month.

Due to their similarities and numbers, the dominant Ratgeot is decided by whose hair is the longest. Some Ratgeot try to cheat by cutting other Ratgeot's hair with a quick flick of its sharp, claw-like wings.

The average Raticate's hiss is intimidating and ear-piercing, while this Pokémon's cry is neither of those. More often than not, this Pokémon will be forced to go first in a life-and-death situation for the pack.

Ratling will act friendly and comfortable around a regular flock of Fletchlings, only to steal their food at the last second. This behavior showcases how it uses its mixed traits to its advantage.

Ratwag hates anything that comes within its body of water. It doesn't matter if it's food or a full-sized Trainer, it will nibble on it until it's devoured or it flees.

Even though it was meant to be like a pest that's hard to get rid of, many Trainers have adopted Ratortle as an ideal house pet. Its soft tail and tiny ears warm the hearts of many, so they don't realize their food gets stolen at night.

Ratoise's water cannons change in scent and pressure based on its diet. In the worst-case scenario, a Ratoise's Hydro Pump can blast as hard as a fire hose and smell like sewage.

Ratfree is a very invasive fusion that hoards flowers from grassy fields, picking every flower there in minutes. They use the nectar from the flowers to create a cheesy-smelling dew from their antennas to feed their young.

A Ratdrill queen produces two kinds of honey. One that is safe and consumable to its hive, and one that is toxic to wild Pokémon. Ratdrill hives are always filled with this toxic honey, which can make an Ursaring's luckiest day turn instantly sour.

Trainers should avoid petting Ratata unless offering its favorite food. This agile and slippery Rattata has the bite force of its evolution and can leave painful wounds that take a long time to heal.

Ratortle is a master of sneaking away. It is able to hide in its shell to resemble a normal wheel of cheese, and its long, doubled tail allows it to whip opponents, creating a loud and disorienting crack to aid in its escape.

Ratoise has a nest of Rattata inside its shell. These Rattata are responsible for acting as Ratoise's cannons, and attacks for them, just as long as they are fed well enough. On average, a Ratoise nest houses 10-15 Rattata at once.

Speargey is considered an outcast to most Spearow. Its less aggressive behavior will often have it kicked out of any flock it tries to fit in with. Most Speargey will never find where they belong.

The body shape and feather colors of Spearotto are enough to confuse both sides of its fused 'cousins'. Though unlike a similarly shaped fusion, Pidgerow, it instead attacks whoever has the most food on them at any point.

Speargeot is barely different than a normal Spearow. Speargeot is just as territorial, loud and rude, only having twice the temper due to needing much more food than normal, and lacks the flowing, alluring hair of the Pidgeot half.

Feargeot possesses all the best and most helpful traits of the Pidgey and Spearow line. Its speed, size, strength and shining feathers have often confused researchers, thinking that Feargeot is the missing link of the three legendary birds of Kanto.

Mimeling's voice changes based on its environment and the observations it makes. It has a foul habit of imitating the cries of a Pokémon's worst enemy to scare them into leaving their food behind.

Sandfa's scales cannot protect it from harsh sunlight due to its thin skin. It will dance for several hours, waiting for rain to pour so it can quench its thirst. Most of the time, however, it faints from exhaustion.

To avoid predators, Sandras buries itself in the ground near mushrooms to avoid detection. However, even when faced with no hiding options, it will throw out sand and spores to blind and disorient the attacking Pokémon.

Sandude rolls down hills in order to wear down its rocky skin, and then rests to heal and reinforce it. Sometimes, Sandude struggles to fully curl up into a ball due to its limbs and circular body.

Sandnix can divide its body individually to efficiently roll down mountainsides for fast, downward travel. If its body is damaged, it will roll in mud and sit in the scorching sun, filling the cracked spots and hardening its body again.

This Pokémon is theorized to be the sole cause of Zubat overpopulation in most caves of Kanto, being able to produce Zubat eggs without a mate. However, these theories usually came from post-blacked out Trainers after a Supersonic to the face.

The parasitic mushrooms attached to Paba reject it due to the funky scented fluid in its body. This allows it to utilize the two front claws and debilitating spores of its Paras half without acting as a host.

Pafa's one desire is to drink the sweetest dew made from moonlight and grow powerful beyond the moon that the dew came from. It is unclear if this desire stems from Pafa itself or the parasitic mushrooms rooted in its head.

With the parasitic mushroom grown in size and strength, Paraian is no longer able to resist the infection. Now as a host, it flies across small forests, spraying out spores mixed with its body fluid to stun and consume its prey.

Meowuna strives to evolve with some riches in its body. When a Trainer isn't looking at it, it will reveal its hook-like arms to snatch any coins it can find in their pockets and hide them inside its body.

Meowba keeps stolen coins hidden under its wings. When under attack, it will shake its body around violently, making a disorienting ringing sound with all the coins stored inside its shell.

A domesticated Meowish has been observed to be a somewhat reliable coin bank. If it's not fed or loved well enough, it will consume all the coins inside of it instead of storing them.

A thin membrane surrounds Poliling's body, which allows it to float on top of the water. When it needs to dive for food, it sheds this membrane and only needs a minute or two to grow it right back.

Onfa's horn gives off a strange, magnetic energy on the peak of Mt. Moon that has been identified as sonar. Researchers theorize that it is trying to send and receive a message from something among the stars above.

Many people believe that Onfairy is actually a living meteorite that has fallen and resided within Mt. Moon. Another theory that was disproven simply with the act of unfusing... or was it?

Ondude can often be seen wrapping its tail around rocks and breaking them open while flexing. While at first it looks like it's doing it for fun, it is actually training its grip to be stronger to prove fatal to even the hardest-bodied Pokémon.
