WN/Velgaia

"Earth Emperor Dragon" Velgaia「"地帝竜" ヴェルガイア, "Chitei Ryuu" Verugaia」formerly ”Chaos Dragon" Gaia「"", "Kaosu Doragon" Gaia」is the newly born sixth and final True Dragon. He was formed from the remaining energy of the late Veldanava and evolved into a True Dragon after eating the core of "Berserk Evil Dragon" Zero, and being named 'Velgaia' by Rimuru. Unlike other True Dragons, whose titles, are given by the Voice of the World, Velgaia's title of "Earth Emperor Dragon" was also given by Rimuru.

Background
For as long as she could remember, Gaia was Milim's only family as her parents passed away before she got to know them, so when her pet dragon got killed Milim went into a rampage and wiped out the nation responsible. Thus, she ascended to a True Demon Lord. To quell her rage, Guy Crimson and Ramiris subdued her. When Milim evolved, Gaia's corpse transformed into a Chaos Dragon. However, since it did not have a soul, the dragon transcended both good and evil becoming a force of pure destruction.

Milim in her sadness sealed Gaia's body away so that nobody could find it. However, the dragon's energy slowly seeped from its body and ruined the surrounding nature. When the Freedom Association was asked to investigate the miasma, Yuuki found the Chaos Dragon.

Devil's Secret Maneuvers Arc
During Leon and Yuuki 's battle, Yuuki summons the Chaos Dragon that was previously sealed by Milim. Upon it corroding everything around them using Chaotic Breath, Leon quickly seals it with a Holy Attribute Barrier that is much stronger than the Hero's, Infinite Prison, but not before Yuuki has stolen its dragons' core (power) and becomes a Dragon Warrior. Yuuki is now covered by the same miasma that once covered the Chaos Dragon, resembling an ominous black armor resembling scales. Without its core, all that is left of the Chaos Dragon is bones and ash. Even with Yuuki's increased strength he is worthless before Leon's might and loses an arm. In this beaten state, he escapes before he is fully engulfed.

Inside the Red Knight, two souls were found by Rimuru and company. One was of the Red Knight herself and that of the Chaos Dragon, which has now been purified by Leon's previous attacks. With Ruminas' help, the two souls are separated and the Red Knight is revived with the core of the dragon being placed into a jewel in the keeping of Rimuru, however, in doing so Gaia's power was greatly weakened.

An egg is formed from which Gaia is hatched and Milim is overjoyed. Since it was too soon to have him train with Milim; she, Rimuru, Veldora, and Ramiris proceeded to level up Gaia in the Ramiris’ Labyrinth.

Tenma Great War Arc
Gaia later combines with the dragon core of Zero and evolves to a True Dragon. As Gaia becomes Veldora's younger brother, Rimuru named it "Earth Dragon" Velgaia.

After the Tenma Great War, Velgaia helped protect the Sky Castle by using his newly obtained Unique Skill: All Creation Manifestation, which is a skill similar to Ramiris' Labyrinth Creation, since Dagrule was sealed and could no longer act as the Gatekeeper.
