True Dragon

True Dragons are the highest spiritual beings, and are considered the strongest existence in the world, superior to both a True Demon Lord and True Hero.

They are beings "perfect as one," especially durable, spiritual life forms, so they have no attachment to their physical bodies, they only take those forms to respond to the desires of religions or similar (or also for convenience).

Birth
True Dragons are immortal and unblemished beings made of pure energy and formed by sentient beings’ prayers. They are basically god-like beings that represent and embody some aspect of nature.

After a True Dragon is born for the first time, it can never be 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 not have the memories of the previous but simply understand its nature of existence right after birth.

Relationship
Although the True Dragons refer to each other as "brother" or "sister", they are not blood-related in the biological sense.

"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.

"White Ice 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. She was incredibly jealous when Veldanava respected Guy and gave him 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 youngest of the True Dragons. He is connected with Rimuru by an agreement and was known to frequently rampage here and there. Known to act very childish.

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 or even considering her a true dragon.

Trivia

 * In the first databook, Milim is labelled a True Dragon (of course, this is not true.)
