Who is Johnny Thunder you might ask?
Johnny is a Golden Age superhero (or, as they were called back then, mystery man), who premiered in Flash Comics #1 (January, 1940) by John B. Wentworth and Stan Aschmeier. Johnny was born in the Bronx, on the seventh day of the seventh month on a year that ended with seven (1917), but kidnapped by the High Priest of Aissor to be taken to the country of Badhnisia.
Johnny wasn't the only one to weld a Thunderbolt! Here's a look at a few others....
Jonni Thunder, Detective
Jonni was a west coast detective who lived an ordinary life with her '57 Thunderbird...at least until a laser blast hit an old statue of her dad's....and Jonni was able to manifest as an energy being similar to lightning, with all its properties, while her body was unconscious.
Star-Spangled Kid turned Skyman), and found out the plan of the Thunderbolt in Infinity, Inc. #40 and #41 (July and August, 1987), as the Thunderbolt got a name (that of Mzzttexxal, and a male Thunderbolt named Zzlrrrzzzm possessed Skyman to become Skybolt), and Jonni pretty much disappearing after the disbanding of Infinity, Inc. in Infinity, Inc. #53 (August, 1988).
JJ Thunder, JSAThinker's Thinking Cap, and Johnny Thunder had turned it into a flower pot at the old age home he lived in. Johnny also had his Thunderbolt in a pen, which J.J. took, which led to JLA #28 to #31 (April to July, 1999) by Grant Morrison and Howard Porter, where Jakeem helped against an invasion from the 5th dimension, that occupied the JLA and remainders of the JSA (Flash, Wildcat, Green Lantern, Wonder Woman/Hippolyta and the Spectre-force without Jim Corrigan), as well as Captain Marvel face Thunderbolt Lkz, with J.J. releasing Yz, eventually merging Lkz with Yz, giving Jakeem the ability to control the combined Thunderbolt with the phrase, "So Cool", and this Crisis Times Five also led into the reformation of the JSA during the Day of Judgment and the JSA's battle with Mordru.
Jakeem eventually had a solo story as well, in JSA: Classified #28 (September, 2007).
Johnny Thunder, Lawman
Evil Earth-1 Johnnythe Wizard and Chronos), and again manipulating the Thunderbolt for his own ends.
Johnny also had Bahdnesian Kiku Thunder, who was in the 10 issue Justice Society of America series of the early 1990s (with Jesse Quick), and Willpower (William Twotrees) who was revealed to be Johnny's son in issues of Primal Force, but these characters never really broke out of those series, so will likely get more coverage when those series are covered.
