Runner NightBlade is the future son of Alex and Annie. He is the brother of Robin. According to him, Alex was adopted (eventually) by his "Uncle Ender". Runner is extremely fast and agile, having spent a lot of his life running across a black plain, jumping boulders and killing anything in his way. He is able to manipulate some sort of energy, allowing him to become invincible and run at higher speeds for a short time.
