Bates, Swan and Roussos begin a three-part story in Action 385 (Feb. 70), which sees Superman age into the far future.
It begins with a giant, metallic hand that carves a request for help in the door of the Fortress of Solitude. Superman takes a damaged time bubble to get there. Because when you are dealing with something as delicate and dangerous as time travel, why bother taking a working method?
So he gets to the 102nd century, and helps them with their currency thefts. But his body aged during the trip, and he now looks extremely old.
Superman attempts to get back to his own time, but neither the bubble, nor he alone, can get through an impenetrable time barrier, constructed by the Time Trapper, who is enjoying Superman’s distress. This is the first time the Time Trapper has dealt with Superman, as opposed to Superboy, with the Legion. This also marks the Time Trapper’s first appearance since his weird “defeat” story in the early 60s.
So Superman is stuck in the 102nd century. His body has super-strengthened itself over the years, and he is no longer weakened by kryptonite, magic, or even virus x.
The story continues in the next issue.
Star Boy gets the starring role (hah! did you catch that?) in this Bridwell/Mortimer/Abel story.
An emergency call comes in from Xanthu, Star Boy’s home planet, and he requests to be sent on the mission. Karate Kid agrees, and sends him along with Saturn Girl and Colossal Boy.
The emergency was real, but designed to draw Star Boy there. The brother of Kenz Nuhor, the man Star Boy killed years earlier, has drawn him here for revenge. He traps Star Boy in a weightless environment, thinking that was neutralize him. But Star Boy’s powers affect mass, not weight. Which are different. I vaguely recall that from high school. Different enough that they work, and Star Boy takes down the brother as well. But doesn’t kill him.
