 Played by Paul Putner, Harry Hayes is the fourth member of KENT, responsible for technological development.Though previously a handsome physically spectacular specimen of a man, he was badly injured when Professor Nebulous disintegrated the Isle of Wight, having entered the unshielded control room to try and reverse the process and being badly injured in the resulting blast.He was rebuilt by the Professor and lives his life in constant agony while trundling around in a wheelchair constructed from old kitchen units, though in recent episodes the Professor has given him a new hover chair with slat grates that allow him access to everywhere he could want to go (Which just annoys Harry more as he has less to moan about now).
