Synopsis for Superman and Batman: "Execution on Krypton!"
After an experimental time-flux snatches Jor-El and Lara from old Krypton to Earth for a few moments, they speak of committing a crime and are heard by Superman and Batman, who decide to travel back in time and space to investigate.
The Duo arrive at Krypton and they locate Superman's parents, who are still law abiding citizens. Batman and Superman decide to investigate Jor-El and Lara's activities and they learn that they are apparently running a school for criminals. However, after passing a severe test, the heroes learn that Jor-El and Lara are training people to go to a planet where stealing is the law in order to retrieve an ancient fossil. After witnessing Batman and Superman's abilities, Jor-El and Lara decide to send them on the mission.
Batman and Superman succeed and retrieve the fossil of an ancient leader, but upon returning to Krypton, they are snatched back to their right time and learn that the time disturbances were caused by experimental machines created by the military.

Synopsis for Robin: "Stone-Deaf Robin!"
This story is reprinted from Star-Spangled Comics #130.
A thug by the name of Fixer Bannon approaches Dick Grayson and throws a grenade at him. Bannon is sure that Grayson is really Robin. The grenade lands and explodes inside a nearby trash can shielding Grayson from serious injury. Robin is ok but he temporarily loses his hearing for a period of 48-72 hours. In the meantime, the newspapers report the details of Graysons attack. They report that Grayson is temporarily deaf and this detail is picked up by Fixer Bannon himself. Bannon reasons that if Grayson is deaf so is Robin. Dick Grayson also makes the same conclusion and he realizes that he must hide his deafness to protect his identity as Robin. He is summoned by commissioner Gordon where Robin displays his excellent lip reading abilities to communicate with Gordon. The commissioner informs Robin that Bannon was last seen near the Budd Museum Warehouse. Robin rushes to the dark warehouse where Bannon lays in wait with a gun. As Robin approaches, Bannon fires a couple of shots. Surprisingly Robin is able to detect the two shots. Bannon fires two more but again, Robin seems to know that a gun has been fired once more. Bannon surmises that Grayson and Robin cannot be the same person since Grayson is temporarily deaf. Robin apprehends the fixer and hands him over to the authorities. Robin later reveals to Batman that he was able to detect the gunshots by placing his hand on a glass top showcase. The glass would then vibrate each time Bannon fired his gun thus protecting his secret identity.
