North America (New Pleistocene)

North America has relatively stayed the same as it was during the Holocene, but due to natural disasters, Florida and most of California separated from the Rest of North America, invasive species turning Florida into a rainforest and most of California becoming a savannah. Many species thrive and are still around today.

Yukon Grassland
Stretching from Montana to Canada, originally boreal forest, the migrated herding animals, turned it into a rich grassland, due to the grazing of large herbivores, that control the level of grass and trample the ground.

Mammals

 * Reindeer - A large cervid found throughout Northern North America and Eurasia. Also known as caribous, they run in large herds similar to cattle or bison and have large antlers. Humans in ancient times used them for food and transportation.


 * Montanan Horse - A descendant of the mustang that migrated upward, they evolved thicker bodies and longer fur.


 * Yukon Wolf - A large species of wolf, descended from a group of gray wolves, common throughout the grasslands of the north. Yukon wolves have evolved to be similar to the dire wolves of ancient times, thus, instead of canis lupus, Yukon wolf's scientific name is canis maximus.


 * Gray Wolf - A large species of canine. Same species alive today.


 * Canadian Dylanus - Descended from feral dylanus/American common dylanus hybrids. They are omnivores. They are similar to their ancestors, but are now covered in thick fur to survive the cold.

They are heavier than any modern type of tiger, reaching 900 pounds due to it being in an Ice Age. They feed on fish in the many Canadian lakes.


 * Wood Bison - A subspecies of bison, widespread throughout North America. They are slightly bigger than modern bison.


 * Northern Elk - A northern subspecies of elk, more adapted to colder climate. It is the most widespread of all the subspecies of elk.


 * American Fallow Deer - Descended from fallow deer introduced to North America by humans. They resemble a European fallow deer.

Adult Gutsman.EXEs can be about 16 feet tall and weigh about 2 tons. They are no longer sapient, so they now only behave, eat, and walk like gorillas, but are a lot more peaceful than gorillas, about as peaceful as the aquatic manatee. Unlike their ancestors and unlike other Net-Navis, they could no longer talk as this ability is not important for herbivorous Gutsman.EXEs, so they communicate by snort, grunt, growl, moan, bellow, and roar. Other than that, they are similar to their ancestors. Their only natural predators are Elecman.EXEs, Bass.EXEs, Allosaurs, Tyrannosaurs, and large terror birds, fortunately, most of these predators don't live in the Yukon grasslands (but Bass.EXEs and species of Tyrannosaurs lives here as Gutsman.EXE's only natural predators in the Yukon grasslands). Gutsman.EXEs live in herds up to about 95 in a single group. They often migrate with herds of bison to search for new feeding grounds.


 * Bass.EXE - In the Late Holocene, humans have mastered universe travel. People have brought many species and sapient beings, including Net-Navis from Megaman Battle Network.

Their descendants now includes not just males, but also female Bass.EXEs, allowing them to survive in the world without humans. They can hover, have darkness, Aura powers, and are almost invincible, having many powers and are almost impossible to kill, according to the Megaman Battle Network games and anime, and can attack anything they need (including prey items they need in order to survive) or want. They are nocturnal, as they can blend in the dark to hunt deer, ibex, wild sheep, and other animals. They have even more advanced intelligence, culture, tech, etc. than humans. They are similar to their ancestors from Megaman Battle Network series. They eat the similar kind of food as modern humans. They are hostile, according to Megaman Battle Network games.

Reptiles

 * Charizard - Charizard is a draconic, bipedal Pokémon. It is primarily orange with a cream underside from the chest to the tip of its tail, which burns with a sizable flame. Charizard has a long neck, small blue eyes, raised nostrils, and two blunt horns protruding from the back of its rectangular head. There are two fangs visible in the upper jaw when its mouth is closed. Two large wings with teal undersides sprout from its back, and a horn-like appendage juts out from the third joint of each wing. Charizard's arms are short and skinny compared to its robust belly, and each limb has three white claws. It has stocky legs and cream-colored soles under its feet. As Mega Charizard X, its body and legs appear more physically fit, though its arms remain thin. Its skin turns black with a sky blue underside extending from the lower jaw to the tip of the tail. Two spikes with blue tips curve upward from the front and back of each shoulder, while the tips of its horns sharpen, turn blue, and curve slightly upward. Its brow and claws are larger, its snout is shorter, and its eyes are now red with white pupils. It has two small, fin-like spikes under each horn and two more down its lower neck. The lower trims of its wings are divided into large, rounded points and each third joint is adorned with a claw-like spike. Mega Charizard X breathes blue flames out the sides of its mouth, and the flame on its tail now burns blue with increased heat. When Mega Evolved as Mega Charizard Y, this Pokémon becomes more sleek and expansive in appearance, but retains its normal coloration. However, it now has white pupils. It has three pointed horns on the back of its head, the middle of which is longer. Its shorter snout has larger fangs and a ridge on the nose. Its neck is shorter and its hands are much smaller, but its torso and legs are longer. Small wings develop on its wrists, while the ones on its back become larger and now have ragged edges. The back of its tail has a large thorn at the base and three smaller ones near the tip, which now burns with a longer flame. Mega Charizard Y is said to have incredible flying prowess, being able to reach incredible heights. This Pokémon flies in search of powerful opponents to battle, and its fire will burn hotter as it gains experience. Its fiery breath is capable of melting boulders, massive glaciers, and has been known to accidentally cause forest fires. Charizard typically inhabit mountains and valleys.


 * Metagross - Metagross is a robotic Pokémon with a turquoise, disc-shaped body and four legs. The main body appears to serve as both head and body, and this Pokémon’s overall construction gives it the appearance of a mechanized arachnid. It uses its heavy body to pin down its prey before consuming them with its large mouth. A large, metallic cross is situated in the center of its face. On either side of the cross, a red eye peers out from a space in Metagross's metallic armor. Its four legs are joined to the main body by ball-and-socket joints. While the upper portion of the legs is relatively thin, they are considerably thicker below the knee. Each leg has three short claws on the end and a flat, blunt protrusion extending over the knee. The legs can be tucked in, allowing Metagross to float in the air. As Mega Metagross, it constantly floats, and its legs become arms. The cross on its face turn pale gold, and it gains two small holes and a spike immediately below the cross, giving the impression of a goatee. Its multiple brains process information simultaneously, enabling it to calmly assess the tide of a battle and defeat its opponent with accuracy. Mega Metagross also uses the psychic power inside its body to launch powerful attacks. Its claws are hard as steel and can easily smash even large chunks of rocks. Metagross is the result of two Metang fusing together. This gives Metagross four brains in total, all connected by a complex network of neurons. Because of these complex connections and the number of brains, this Pokémon is capable of complex calculations and is more intelligent than a supercomputer. It uses its intelligence to analyze its opponents during battle. This Pokémon can be found on rough terrains.

Torterra's small, red eyes are encircled by a black ring. Its legs are thick and they have four toes each, which appear as if they are actually jagged stones. There are three toes on the front and one on the heel. Torterra's large and clean shell supports the lives of many small Pokémon, which occasionally gather and build their nests upon the shell. Some are born and spend their entire life there. Torterra migrate in search of water, creating the illusion of "moving forests". However, it is typically immobile.

Raizekusu have also been observed eating Neopteron like Vespoid and lesser predators like Velocidrome. Despite being top predators, Raizekusu have to compete with other large predatory monsters like Rathalos, Najarala, Seregios, and Seltas Queen. It also has to compete with rare, powerful monsters like Rajang, Deviljho, and Elder Dragons. Raizex's whole body is an electrical organ. As a Raizekusu fights and becomes more active, certain body parts will begin to charge up with electricity quickly. Its tail, wings, and crest are the only parts of its body that will become electrically charged. This can easily be seen by looking for green surges of electricity on those parts of its body. The more charged up it is, the more range and power its electrical attacks have. Throughout the Raizekusu's whole body is a razor-sharp shell covered in spikes. This shell can easily cut up prey with just a single touch. Raizekusu's flying abilities are comparable to a Rathalos with the help of its powerful wings. Its wings are tough, covered in spikes, and are even used as weapons on the ground. The wings can also produce a special electrical charge used for capturing prey. Its pincer-like tail is used for capturing prey and paralyzing prey.


 * Garchomp - Garchomp is a bipedal, dragon-like Pokémon that is primarily dark blue, with a red underbelly that covers from the middle of its abdomen, to its jaws, and then to the undersides of its arms.

It has four fins, one on each arm, one dorsal fin and another on its tail that resembles a shark tailfin. The male's dorsal fin has a notch on it. It has spikes on its hind limbs and arms as well as sharper claws than its previous evolution. Its eyes have black scleras and gold-colored irises. Its pupils have shrunk. When Garchomp Mega Evolves, it grows in size and several of its features become more angular, including its head and shoulders. Ten spikes sprout from the sides of its abdomen, two spikes on the bottom of each arm, and its hands morph into sharp, red blades. Red spikes also begin to sprout from its knees. Garchomp can fly at an incredible speed—helped by the fine scales on its body that reduce drag—to catch its prey. Garchomp are cave-dwellers, and are seldom.

The underbelly is gray with white borders, and it has a long tail with two orange spikes near the tip. Its small forelimbs have only two black clawed digits, but it has powerful hind legs with three sharp, black talons. Plated, armor-like ridges are found on the front of the legs and down the back and tail. Spiky, white "fluff", similar to the primitive feathers on many dinosaurs, extends into a cape-like fringe around the neck. Additional feathering forms a prominent beard on the lower jaw, which is otherwise gray in coloration. Its head is proportionally large, with a ridged snout and powerful jaws. The lower jaw is lined with pointed teeth, and the upper jaw features a number of tooth-like projections which are also highlighted orange. Its eyes appear to have black sclera with white irises. An orange, five-pointed crest extends from the snout above the eyes and point backwards, giving it the appearance of wearing a crown. Before its extinction, wild Tyrantrum used to live 100 million years ago, when its powerful jaw conferred its status as an unmatched predator. Since it was considered invincible in the ancient world, it behaved like a king.
