In Sonic and the Secret Rings, the Aqua Ring is referred to as the Water Blue Ring and was the fourth World Ring Sonic obtained. It originally belonged to Sinbad the Sailor who used it to control the storms, but it was stolen by Captain Bemoth. Needing the World Ring to defeat the Ifrit Golem, Sonic and Shahra took it back from Bemoth at Pirate Storm, and Sonic felt its power when he grabbed it. Using the Aqua Ring at Evil Foundry to create a storm, Sonic weakened the Ifrit enough for him to defeat it.

During the final confrontation with Erazor Djinn, Sonic used all the World Rings to access Erazor's inner sanctum, before the djinn got Shahra to hand them over to him. Absorbing the Aqua Ring along with the others while their control was still incomplete, Erazor transformed into the monstrous Alf Layla wa-Layla. Sonic, however, took the World Rings of Hatred, Sadness and Rage to become Darkspine Sonic and literally beat the World Rings' power out of Erazor.
