In the cartoon series, the Legion recruit a Clark Kent who hasn't even unlocked flight yet. In the comics, they usually have him join as Superboy.
Why? Why not go forward in Clark's timeline and recruit him in his prime? Clearly, it's possible in the cartoon; Brainiac recruits an older and more experienced Superman in season 2.
Hell, if Clark is still alive and well in the 31st century, why not recruit THEIR Superman?
