"This is Gaia's light, I guess."
|First Appearance:||Ultraman Gaia episode 3 "His Name is Gaia"|
|Status:||Active as of Gaia Once Again|
After Ultraman Gaia defeated C.O.V, he turned back into Gamu. Gamu found a strange light on the battle which he sensed was important, using a photoelectron tube he had on him, he took it. Later on, he used it to transform into Gaia a second time. Gamu later built the Esplender to properly house the Gaia force as a more suitable device. In Ultraman Gaia episode 26, Hiroya Fujimiya gave the Esplender Agul's light, transforming Gaia into Version 2 (V2). The Esplender was later drained of its power by Zogu, rendering it useless. Later in the Ultraman Gaia direct-to-video special Gaia Once Again, a race of advanced undersea beings restored Gaia's force.
- Before the usage of Esplender, Gamu first stored Gaia's essence in a photoelectron tube while raising it to the air to transform mirroring Shin Hayata's transformation of Ultraman via the Beta Capsule.
- The Esplender is the first transformation device shown to be created by human hands.
- It is also the first to demonstrate the principle(s) of Transformation Devices. That being the storing and unleashing of the Ultra's essence for the purpose of transforming.
