Michal Minato (湊 ミハル, Minato Miharu) is a young man from the future who operates as the heroic Kamen Rider Aqua (仮面ライダーアクア, Kamen Raidā Akua). Michal is a very timid young man who was chosen to become Aqua, but was actually afraid of the water that powered the Driver. Because of this, it sapped his confidence and made him fear monsters. When Kougami offered him the stronger Poseidon Driver in the hopes of overcoming the fear in Michal, it did not work as Michal had decided to call it quits after losing. That would eventually cause Poseidon to turn into a Greeed and possess him into doing its evil work. Coming into the past, he admited to Eiji about his fears and did not understand how Eiji was able to become so strong and wished to become stronger. In the end, Michal came to the conclusion that what he needed wasn't power, but the courage to fight, something he lacked when he first became a Rider. Using this newfound courage, he defeats Poseidon and the rest of the dummies created by Kannagi.
