In "Part I: The Composite Superman!", a chance lightning strike transforms Joe Meach into the Composite Superman, a being forged from the combined powers of the entire Legion of Super-Heroes. With strength surpassing even Superman’s, he seems unstoppable—until his powers begin to wane, leaving him stripped of both his abilities and his memories. Batman and Superman are left puzzled by his sudden disappearance, unsure of who he was or where he went.

In "Part II: The Battle Between Titans!" from World's Finest Comics #142, Composite Superman—once a fusion of Superman and Batman's powers—turns against his creators, threatening to expose their secret identities unless they retire. As his powers wane and he can no longer replicate the original lightning strike that forged him, he vanishes without a trace, leaving Superman and Batman puzzled by his sudden departure and uncertain of his true origins.

In "Flame Dragon from Krypton!", a fiery Kryptonian Flame-Dragon descends upon Earth, threatening to burn through everything in its path. With Red Kryptonite nearby and Superman forced to keep his distance, he must outwit the beast using cunning, cold, and a little help from unexpected allies—Krypto, Batman, and Supergirl—while keeping his identity hidden from Lois Lane.
