Superboy Vol. 4 No. 30, DC Comics, August 1996

"Superboy beats on Victor Volcanum some more, who asks for a clean death. Knockout goads him on, telling him to kill Volcanum, but Superboy won't do it--so KO does it herself. Superboy realizes that all the rumors about her were true, and that he's been played for a harp. Some robots walk in and confirm Volcanum's death, thereby beginning a detonation that will cause the island to sink back beneath the waves. Knockout wants the island high and dry and orders Superboy to whatever she says from now on, but he casts her aside and finds the scientists and Tana Moon that were being held on the island. He grabs them all and takes them to a nearby boat where the Special Crimes Unit is waiting. SB admits that he screwed up bad, but will make up for it by bringing in Knockout. Before he goes back to the island, Roxy (who had come with the SCU) puts the S-Shield back on his suit."
