Noah Gray is a fictional character on Heroes and is the son of a reformed Sylar and Elle in the future. He lives in the Bennets' old home in Costa Verde with his dad and Mr Muggles. It seems he is named after Noah Bennet. When he met the present Peter Petrelli, he called him "Uncle Peter" even though it has been proved that Peter and Sylar are not related.
Noah was killed when there was an attack on his home which caused Sylar to glow and blow up Costa Verde.
