True Dragon

True Dragons (竜種) are the highest ranking beings in existence. They're nigh-invulnerable and nigh-unstoppable avatars of nature that serve as the pillars of all creation with only five known to exist.

Appearance
True Dragons, as nature itself incarnate, and as spiritual life-forms, do not have a set singular appearance or form. They can assume the appearance and properties of whatever they wish, with no real attachment to their bodies. As spiritual beings, whatever form they assume will be affected by their own personal self-image and individuality. True Dragon's typically assume a massive lizard-like form covered in scales and bearing horns and wings, in addition to a secondary human-like form, with Rimuru's Slime Form being a notable exception. Their large draconic form is capable of taking and dealing much more damage, while their human form is far more energy efficient and is better suited for long-term battles.

Birth
After a True Dragon is born for the first time, it can never be truly killed. Even if the individual itself is killed, another True Dragon of the same natural characteristic will be born anew somewhere else. That new True Dragon will have the memories of the previous but might lose some aspects of its personality, while simply understanding its nature of existence right after birth.

Intrinsic Skills
Although each True Dragon is "Unique" and has different intrinsic abilities, all five of them share three intrinsic skills in common.


 * Dragon Spirit Haki
 * Powerful Haki that imbues the user's aura with magical and physical properties, shredding anything it comes into contact with.
 * Universal Sense
 * Allows the user to perceive almost all sensations including but not limited to, light, sound, smell, and heat in a wide radius.
 * Universal Shapeshift
 * Allows the user to freely change their body's properties and disguise their appearance.

"Star King Dragon" Veldanava
The greatest of the True Dragons and the strongest among them. He is also the God that created the world in which they live. The husband of Lucia and father to Demon Lord Milim Nava.

"Frost Dragon" Velzard
Partner of Guy Crimson, Velzard is known to be second in birth as well as in power from Veldanava. She is prideful and haughty, and was incredibly jealous when Veldanava granted Guy important roles instead of paying attention to her.

"Scorch Dragon" Velgrynd
Partner of Rudra Nam Ul Nasca, Velgrynd is the fastest Dragon in existence. Her very essence is that of 'acceleration' and 'high momentum'. Although slightly hot-headed, she is very compassionate, especially to her allies and family.

"Storm Dragon" Veldora
The personification of chaos and destruction who terrorized humanity for thousands of years and is infamous as a result. Despite bearing rational thought and intelligence he rampaged even right after he was born, being treated harshly by his sisters for his behaviour ever since. After meeting Rimuru, Veldora learned how to control his power and gained some slight semblance of restraint.

"Chaos Creator" Rimuru
During the events of The Abyss Unleashed, Rimuru's latent potential and power as the fifth True Dragon is fully realized. This results in his Reincarnation into a fully draconic body with similar physical properties to a slime called Ultimate Slime (竜魔粘性星神体). Despite having no direct relation to slimes, it is still named as such for the sake of convenience.

Milim Nava
A Dragonoid, she is one of the oldest and strongest Demon Lords. The daughter of Veldanava and Lucia, she inherited the greater part of her father's power resulting in many comparing her to True Dragons.

Gaia
As an offshoot of Veldanava's power and as his potential vessel for reincarnation, Gaia's body, and possibly Gaia herself, has the potential to reach the level of a True Dragon, as indicated by her corpse reaching the level of a Catastrophe class just from Milim's Harvest Festival gift.

Charybdis
Similar to Gaia, Charybdis is an offshoot of a True Dragon, in this case an offshoot of Veldora and inherits similar qualities, albeit being much weaker.

"Headwind Dragon" Veldora Against
A copy of Veldora appeared in That Time I Got Reincarnated as a Slime: Isekai Memories, he has all the powers and abilities of a True Dragon. Created by Izis in the Mirror World unintentionally when she created Shinsha. He's currently sealed away within Izis following her defeat by Shinsha and Rimuru.

Differentiation From Regular Dragons
Dragons are beings born from the released "Essence" of Gaia in places with high magicules when she became the Chaos Dragon. Although they cannot compare in terms of existence or power, often even outright called an entirely different lifeform, their appearance is still extremely similar.

Trivia

 * In the first databook, Milim is mislabeled as one of the 4 True Dragons.
 * In the second databook, Gaia's race is listed as 竜種 which refers to True Dragons, without any further elaboration.
 * As there is no set standard for members of their race and because of the circumstances behind their birth, True Dragons are each individually considered "Unique Monsters".
