Species List

Species Name: Imin
Appearance: The Imin start their lives off as viscous blobs of teal-coloured slime. But if they can find some extra-mass, like say a human-being or another slime Imin then they can absorb that and use it to change their shape.

The Imin don't have any limits as to what they transform into, they can look like the human host they absorbed, or anything else.
Abilities: The Imin are shapeshifters and can take any form they desire as long as they have enough biomass (hence why the slime monsters can't change, they're too small).

After they assimilate another entity, which allows them to shapeshift, the Imin also gain a lot more personality.
Other Information: The Imin are led by a hierarchy with the Imin Queen on top. At some point they were sealed or defeated, thus there aren't many of them currently, but they are on the rise.

Species Name: Phantom
Appearance: Varies based on the individual
Abilities: Varies based on the individual
Other Information: Based on mythical creatures, the Phantom are a race of magical creatures which exist only to create more of themselves, in the hope that their master, known only as "Wiseman", will come into this plane to dominate it. How they go about making more is they track down special humans with magical potential known as "Gates". They then crush the Gates's hopes and dreams, allowing them to give into despair. When this happens, a new Phantom is born, but it needs to still break free of the human, much like a baby chicken must break out of the eggshell. As this happens, purple cracks appear on the Gate's body. The only way to save a Gate after this is for a magical Rider, such as Wizard, to travel into their subconscious and destroy the Phantom from within.
Phantoms can only be killed with magical weaponry, such as silver bullets or weapons.

Species Name: Mirage (plural: Mirages)
Appearance: It varies. The individual bodies of the Mirage are all different. They all have some form of aquatic motif, such as fins somewhere on their body, or gills, or fins. Anything else is based on the individual member of the species. They could be animal based, which would include non-aquatic animals as well, but they all have the aquatic motif somewhere, and have a blueish colored body that shimmers somewhat.
Abilities: They have the ability to take on a human form, but have no natural human form. The forms they take are composites of various individuals. The eyes of one, the facial structure of another, and so on. When they change from human composite to their Mirage form, their bodies appear with a lit, stained-glass style appearance. Other abilities vary from Mirage to Mirage on their natural form, and what powers that form contains. They all have the ability to swim exceedingly well, along with breathe underwater and manipulate water.
Other Information: Creatures that exist primarily in Suito, they are ancient creatures that were awakened from their slumber while Suito was constructing the large fountain in the center of the city (larger, of course). The Mirages began to appear after that, attacking and killing people, taking on composite images and living among the humans. Most remained in their ancestral homeland, while some left to go to other locations. For now, their enemy is Storm Ryuudou, Kamen Rider Aqua, standing as the current guardian of Suito.

Species Name: The Wraaath
Appearance: Each has a unique appearance
Abilities: Varies, although Fen generally has control of earth and gravity, Yaro generally has electricity and water, Kido has wind and light and Iramus controls darkness and metal.
Other Information: The Wraaath are powerful alchemical automatons, created by ancient scientists not long after the Greeed came and went, for one purpose and one only- to prevent something like what happened with the Greeed from happening again. They have the ability to change between human and monster guise at will, and are very distinguishable by their eyes. Their eyes are fully colored, as in the color is not restricted merely to the iris, but covers the whole eye except for the pupil.
They derive their powers and life from their weaponry, powerful swords created by the ancient group of alchemists and wizards who made them. Anyone who wishes to access their power must wield the blade in battle, and legends speak of chosen knight who can wield such blades.
The Wraaath are not inherently evil. In fact, they are actually fully good, despite their monstrous true forms. They only wish to prevent humanity from destroying themselves.
