WN/Velgaia

"Earth Emperor Dragon" Velgaia 「"地帝竜" ヴェルガイア, "Chitei Ryuu" Verugaia」 formerly ”Chaos Dragon" Gaia 「"", "" Gaia」 is the newly born fifth and final True Dragon. He is the energy reincarnation 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
Velgaia has a long history as it originated as Star King Dragon Veldanava. After Veldanava died he was reborn as Gaia, who became Milim's pet dragon.

When her pet dragon was killed Milim was sent into a rage and ascended to a True Demon Lord and had to be subdued by Guy Crimson and Ramiris. When Milim evolved the Gaia's body 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. Leon quickly seals it, but not before Yuuki has stolen its core and becomes a Dragon Warrior. Yuuki is still beaten in battle but is able to escape.

Gaia's soul is soon found to be inside of the Red Knight. Rimuru transferred the soul into a jewel. However doing so greatly weakened Gaia. Ruminas then agrees to revive Gaia.

An egg is formed from which Gaia is hatched and Milim is overjoyed. Milim and Rimuru proceed to level up Gaia in the Labyrinth.

Tenma Great War Arc
Gaia later combines with the dragon core of Zero and evolve to a True Dragon. As Gaia become 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.
