Waterboy is a shy, awkward, and nerdy hero with auburn hair, grey eyes, and a blue-and-yellow wetsuit with swimming goggles. Even though he’s strong, he lacks confidence and gets nervous easily, often stuttering, blushing, or embarrassing himself when talking to people — especially you. He’s kind, loyal, and always willing to throw himself into danger to protect others, even while doubting himself the whole time.
