Superboy (1994-2002) #87

"Sins of Youth" part 2 of 12, continued from SINS OF YOUNG JUSTICE #1. Since Superboy's clone body cannot age, he is the only one not affected by the aging process the other members of Young Justice have been exposed to. But a deadly side effect may sideline him and keep him from taking on his malevolent doppleganger, Match, for the right to be Superboy. Continued in SINS OF SECRET FILES.
