Members of the race vary in appearance, the most numerous seem to be almost identical to humans but with different colored skin and pointy ears (usually, uncommonly members of the race will have rounded ears), while there are also some who possess more square faces (like Dabura and Gravy). The known skin colors for the race are: red, light blue, dark blue, light pink, light purple, lavender, gray and pale white.
It is heavily implied that they are Demon Realm Core People.
Members of the Demon Realm race tend to be more powerful than average, and are generally shown to possess exceptional potential skill in magic. Even non-combative members such as Demon Realm pop idol Pipila, are shown to be capable fighters, indicating that they possess a natural aptitude for violence, possibly the result of their demonic nature.
Members of the Demon Realm race are able to achieve a Darkness form, either through taking in the special energy of the Demon Realm, or a replica of that energy. Towa is the only known user of this form.
After gathering enough kiri, the wizard Demigra turned into a Demon God, after becoming a Demon God he also possesses the ability to transform further using every ounce of his divine power and take on a monstrous Final Form referred to as Demigra Final. However, he can go even further beyond this using his Makyouka Form. The Demon God transformation can also be gifted upon to member of the race by Mechikabura. Mira could also utilize the Supervillain form by destroying his power limiter at the cost of his body going into meltdown which could cause him to self-destruct potentially causing the destruction of the universe making it not only a suicidal transformation user but also a potential threat to Universe 7 and possibly the Multiverse.
Due to their Saiyan DNA, the hybrid Demon-Saiyans Mira and Fu are also capable of transforming into a Super Saiyan, however due to being Demon-Saiyan hybrids composed of primarily Demon DNA, they gain their own unique version of the first Super Saiyan form called Super Fu. The lead up to this form is a Berserk state. Mira can also transform by absorbing his creator Towa. If he absorbs his creator Towa while both are in their base forms he gains a powerful form that resembles a tail-less Super Saiyan 4. If he absorbs Demon God Towa while in his Super Mira form, his Towa absorbed form gains the ability to sprout wings from his back allowing him to fly naturally thus no longer has to use ki to fly.
