BASICS

RexBirbs are anthro dino-bird-like creatures.

Every RexBirb has floating forearms, missing arms completely, with wings connected to it. Most of them have dark colored sclera.

Their floating wings provide them with floating abilities that help them fly, they don’t need to flap their wings much, but they usually do it to adjust the flight course.

 

POSSIBLE SIZES

Rexbirbs have some possible body height variations: Small-sized ones, called NanoBirbs; Regular-sized ones; and Huge-sized ones, called MegaBirbs.




SKELETON

Here’s a representation of an average RexBirb skeleton in adulthood.

RexBirbs bones are usually lightweight which helps their floating abilities, altho it makes them more fragile than other creatures of their size.

 

Abilities

PHYSICAL DEFENSES

All RexBirbs have some natural physical defenses to protect their fragile bones, such as a strong beak/muzzle, used not only to tear meat while eating but also to cause damage to prey and enemies during a fight.

Another physical defense is that their leg muscles are naturally very strong, other than natural great runners, they can use it to carry prey and enemies up in the air and throw them from high places to deal damage, another strategy is to use claw weapons attached to their legs, dealing more damage in a direct attack. 

 

MAGICAL DEFENSES

Because of the natural inner gem growing inside their forearms, most RexBirbs can energize magical stones called Gaia Stones and manipulate its energy.

Those are elemental stones found in places where those elements have a strong power in nature. Those elements include: fire, used to warm up; thunder, used as batteries; earth to help plants grow; water to keep a place humidified; ice to keep places cool; wind to make small objects float and light to keep a place lit.

Some RexBirbs use so much of a single energy that it becomes natural to them to manipulate this kind of energy even without a Gaia Stone, this kind of magical birbs are known as Ascendant RexBirbs.

  

DIET

RexBirbs are omnivores, which means they can eat basically anything from plants to meat. They usually enjoy white meat, small invertebrates, vegetables, fruits, grains and others, also creating recipes from it. Note: All RexBirbs are lactose intolerant.

 

genders and Reproduction

POSSIBLE GENDERS

They can be born with the following sex: Male, female, Intersex or Sexless.

Males usually have a longer thorax and longer beak/muzzle.
They have only male reproduction organs and are compatibles with females and intersex RexBirbs.

Females usually have a thinner thorax, no breasts, larger hips and short muzzle. Even though they don’t have breasts, some grow fluffy feathers on their chests.
They have only female reproduction organs and are compatibles with males and intersex RexBirbs.

Intersex ones can have any of the above features or something in between it.
They have both male and female reproduction organs, they are compatibles with any other RexBirb sex but sexless.

Sexless ones can have any of the above features or something in between it.
They don't have either male nor female reproduction organs, only a cloaca where they eliminate their physical needs, they are only compatibles with other none sex RexBirbs.

Regardless of their sex of birth, RexBirbs can identify themselves as any gender, romantic or sexual identities.
