"Papa John" on how and when to use the Thunderbolt's magic powers. The green-suit-and-red-bow tie-clad Johnny's appearances with the Justice Society of America and in his own solo adventures tended to be quite comedic, as Johnny's main personality trait was being fairly dimwitted, which prompts his much-smarter Thunderbolt to possess a sarcastic (if patient) attitude toward his "boss", while knowing full well that he could not actually do anything until his master told him to. Johnny accidentally joined the Justice Society when wishing out loud that he could be a member and was immediately taken to their meeting by the Thunderbolt. Despite recurring impatience with his stupidity, his fellow JSAers genuinely valued Johnny's good-heartedness and dedication and considered him a friend. Furthermore, the Thunderbolt's vast power may have contributed to Johnny's continued JSA membership, his frequent blunders notwithstanding, since the more competent heroes doubtlessly thought it wise to keep an eye on the pair whenever possible. He finally became a member after the Flash left and the group told him to capture Mister X, which he accidentally succeeded in doing. Like most of the JSA members, he had his aging factor greatly slowed during an encounter with the villain Ian Karkull. Johnny's adventures ceased in the late 1940s when he was replaced in the Justice Society stories by a heroine he had begun teaming up with, the Black Canary. The reason for his leaving the Justice Society is eventually explained to be that his control over his Thunderbolt is weakening, thanks to a spell cast by renegade Badhnesian priests. In the early 1950s, Johnny is kidnapped again by agents from Badhnesia, with the intention of executing their original world conquest plan. Johnny manages to summon Superman, and the would-be conquerors' plans are defeated. Johnny spent some time in Badhnesia afterwards, teaching the native citizens about democracy. He returns home after the country elects its first President. Johnny joins the Justice Society on various adventures. Crisis on Infinite Earths and Ragnarök Following the maxiseries Crisis on Infinite Earths was the one-shot Last Days of the Justice Society of America Special (1986). This book depicted the sacrifice of Johnny and his JSA teammates as they left the 'new' Post-Crisis world and entered into a Limbo dimension. Caused by the actions of Adolf Hitler in April 1945, a wave of destruction appears over Earth even as it is settling down from the Crisis.
