Fan Casting Sonar III in Return to the DC Universe

The son of Bito Wladon, Nikolai (better known as Nick in the US) endured extensive surgery, incorporating his father's technology into his body, allowing him to manipulate sound similar to the weaponry his father used. Coming to America, Sonar took up his father's name, out to conquer Keystone City, leading him to battle with Wally West's Flash, then Kyle Rayner's Green Lantern in New York. In addition to his encounters with Jade and Kyle Rayner, Nick has recently also battled Simon Baz's Green Lantern, and aims to find a way to free his father from Belle Reve.
