Micah Sanders (Noah Gray-Cabey) is Heroes' resident child prodigy, who infuriated his grandfather when he took apart the laptop his grandfather gave him as a gift and began rebuilding it. The 11-year-old actor didn't need to do much research for the role — he portrayed the adorably precocious Franklin Aloyisious Mumford (pictured) on sitcom My Wife and Kids. Perhaps even more impressive, Gray-Cabey was a classically trained pianist by the age of three and was once featured as a real-life whiz kid on Ripley's Believe it or Not.
