Ghostron appeared in the 1971 TV series called Return of Ultraman. Hideki Go was sent on a renegade mission to stop a wild monster on his own, the monster was Ghostron. A monster that is possibly related to or even a sibling to Arstron.
During the mission, Go fired an X bomb missile into the monster’s tail, until eventually Ghostron burrowed away underground. After MAT discovered Ghostron's origin, but suddenly noted the X bomb missile inside his tail. It turned out Go accidentally used the timed version of the bomb that is set to detonate in 10 hours. Ghostron later re-emerged from underground in front of a dynamite factory and fell asleep, making the situation bleak.
At first, MAT tried to use paralysis missiles, but failed. Then Go suddenly appeared with a modified Jeep with an alarm siren built to it to lure the monster. After getting to the safety explosion area, Go ditched the Jeep and transformed into Ultraman Jack and the two started fighting. However, the fight was brief as Ghostron sat back down refusing to fight and with the thought of the bomb detonating in everyone’s mind prevented any further action by either MAT or Ultraman Jack. Suddenly, Jack started burrowing underground by spinning like a drill. Jack then popped up from underneath Ghostron, grabbing onto the monster’s body and he carried it into the Earth’s atmosphere allowing the bomb to detonate safely, while destroying Ghostron in the process.
