Cameo appearance of King Shark (Nanaue) whose first full appearance is Superboy #9 that was published the month after this issue (Superboy #0))
• "Sidarm - One! Superboy - Zero!" - Professor Emil Hamilton arrives at the Honolulu airport from Metropolis, ready for a relaxing vacation free of tense fights between super-heroes and villains. His luck quickly runs out however as he encounters Superboy and Sidearm in the midst of a brutal battle. Sidearm finds himself on the losing edge against Superboy and swipes Professor Hamilton's prosthetic arm. He attaches it to his Techno-Vest and turns the would-be weapon against Superboy only to discover that the Professor's arm is nothing more than a suntan lotion dispenser. Superboy quickly finishes the villain off with his tactile telekinesis, but keeps Sidearm's robotic arm as a souvenir. Tana Moon is present and catches the entire escapade on her mini-cam. Superboy and she race back to the KONA-TV station to edit the footage. While there, Tana overhears her co-workers speaking ill of her relationship with a sixteen-year-old boy. She goes back to Superboy's hotel room and engages in a brief moment of spite with Roxy Leech. Professor Hamilton meets up with Superboy again and asks if he can examine him at S.T.A.R. Labs. Superboy and Tana fly down there and the Professor asks him about his earliest possible memories. He recalls waking up in the Cadmus cloning tanks and breaking free with the help of the Newsboy Legion. After securing his freedom, Superboy (calling himself Superman), met his very first super-villain – Sidearm. The two foes battled one another for the first time on the streets of Metropolis. After the examination, Professor Hamilton gives Superboy a tool designed to aid him in his crime fighting career – a pair of X-ray glasses. He immediately tests them out on Tana Moon. Meanwhile, members of the Silicon Dragons break a creature known as, Nanaue, out of the Kulani Prison on the East side of Hawaii. Nanaue shows his gratitude by tearing into the men, ripping them to pieces.
