Synopsis for "Lost & Found, Part One"
In Salem, the JSA check out the appearance of Doctor Fate's tower. Nabu takes over Dr. Fate's body and the heroes ask him for help finding Jakeem Thunder. Nabu opens a doorway to another dimension where Jakeem is.
On the other side of the portal, in the fifth dimension, Hourman, Mr. Terrific and Stargirl are attacked by Yz, the Thunderbolt's son, Shocko. Yz arrives and stops the fight. He tells the JSAers that Jakeem has turned the Fifth Dimension into a kind of hell.
- First appearance of Shocko since the Golden Age. Curiously no reference is made to his mother, Mildred.
- Mr. Terrific uses Buzz Lightyear catchphrase: "To infinity and beyond" (but he is interrupted).
