Saturn Girl

Saturn Girl along with Bouncing Boy and Brainiac 5 go back in time to the 21st Century to the town of Smallville, Kansas to find Superman to come back with them to the 31st Century and help them defeat the Fatal Five. Superman does not agree at first, but then his mind changes and he goes with them to the Legion HQ in New Metropolis. After she consoled Clark at the Superman Museum because Lightning Lad had made fun of him and his powers, Superman agreed to help the Legion. Together with Superman and the Legion, they defeated the Fatal Five and Superman joins the Legion.
