A young race car driver who died while rescuing a little boy and a dog from falling rubble caused by a fight between Takkong and Zazahn. His valiant sacrifice is noted by everyone, even his friends and the new defense force MAT, but an unseen being also took notice. Looking over him was Ultraman Jack, who was so touched by his heroics that he decided to merge his own life-force with Hideki's, thus bringing him back to life (just like the original Ultraman did with Shin Hayata), much to everyone's astonishment. MAT asked him to join the team, to which he agreed, especially since, in this frightening new "Age of Monsters", the Earth would need a savior. In times of crisis, Hideki Go would raise his right arm, and by force of will, transform into Ultraman Jack to fight monsters.
