Astronaut/Cosmonaut Fizz Concept

Just some fan art I was messing around with the other day, I liked the idea of Fizz and Naut being rivals and this kinda sprung to mind, where rivals had to work together or fizz was just an opposing astronaut to Naut. I still haven't figured out a final design for his shark but considering he kinda rides it into battle from his champion comic, I figured it would be like a space rocket/racer that he cruises into battle with, kinda like Super Galaxy Rumble; I forgot to save my design for this.
