>>108633255Supervillains of the 31st Century kidnap Jon, but:
"You idiots! You snatched the wrong Superboy!"
Some of his accomplices want to kill him anyway, but the big boss is blasé and frustrated, citing that Jon doesn't end up doing much later in his life for murdering him to matter. Said big boss is on the cusp of sending a very insulted Jon back, but the lad is "rescued" by the Legion. Not wanting to grow up ingloriously, Jon basically fibs his way into staying in the 31st Century to learn how to be a better hero in a sort-of reverse Booster Gold situation since he can just be "returned" at the moment he was snatched. No big deal, he thinks.
He winds up being very wrong.
The villains that kidnapped him in the first place are recurring antagonists and occasional allies. And Jon's going to need all the help he can get.
