In the future, the descendants of the Ulu Watu very quickly joined the resistance against Dregn after the poisoning and then complete drying-up of the oceans by the Vortex's crystallization. Hydraereva, the only bioroid able to evolve in the marine environment thanks to a special coating, had always dreamed of exploring these great bodies of water, which is why Maana Cercei gave her the job of protecting the coastline. But what are those people over there up to? Surfing? Well, I'll have to give that a go!!
- Exploration: Inflict 150 Damages with Hydraereva

Advantages & Disadvantages
- The boomerangs she uses in her fourth and fifth levels bear a resemblance to the ones Oraya use, while her name sounds similar to Tanaereva Cr's.
- She also bears the facial fins of the Aquanis, a race of amphibian creatures who have membership in Ulu Watu. (Namely Naliah, Numar and Lianah Ld)
