A chemist who discovered the miraculous chemical Miraclo, Rex Tyler became the super-hero Hourman, able to use extraordinary abilities for an hour at a time.
1.) The CW has expressed interest in the character in the past.
Michael Caleo (Ironside, The Sopranos) was planning to pen the script and executive produce the drama alongside Dan Lin and Lin Pictures' head of television, Jennifer Gwartz, for Warner Bros. Television, where the banner was under a two-year overall deal.
Hourman was presumably supposed to follow The Flash if the show broke off big which it did. But I read one review about "Blast Radius" and a reviewer mentioned that the Mirakuru serum (Japanese for "miracle"), might be the Miraclo drug from the comics... that Hourman uses to get his super-strength.
So I haven't heard yet that the Hourman CW show will feature anything other than prophetic visions. But... could Mirakuru be a backdoor intro to the Hourman series?
2.) He has predecessors/sidekicks just like other superheroes.
Just like the Flash introduced the Golden Age version of their hero in the sophomore season of the hit show on the CW, Hourman can follow suit.
Rick Tyler is the son of Wendy Harris and Rex Tyler, the original Hourman, and the president of his own chemical company. Rex Tyler wanted his son to make a career in medicine or the chemicals industry but Rick, despite his intelligence, seemed uninterested in applying himself to a career. His only interest was in becoming an artist but Rex disapproved. Discovering of his father's super-heroic endeavours, Rick could not help but aspire to take Miraclo himself.
Hourman is a two-year-old android from the 853rd Century, he was created by Tyler Chemorobotics using genetic software is patterned after the Miraclo-enhanced DNA of Rex Tyler, the original Golden Age Hourman. Thus, while this Hourman is a machine, he nonetheless qualifies as a 'descendant' of Rex Tyler's. In the year 85,271 A.D., Metron of the New Gods will appoint the young android as his heir and entrust him with the Worlogog , an artifact that can control and manipulate time itself. But Hourman forsook his post as Metron's apprentice and traveled back to the 20th Century to explore his human heritage alongside the Justice League.
3.)He became a valued member of the Justice Society and the All-Star Squadron.
In 1941 Rex left the JSA for Uncle Sam's Freedom Fighters and later joined the All Star Squadron. Later on Rex Tyler would find out that he was addicted to Miraclo. Since this discovery Rex has found different ways to access his powers without addictive risks. He first beat his addiction by developing a non-addictive formula of Miraclo. Then later, he began to use a black light lantern (similar to Alan Scott's) to activate the residue of Miraclo dormant in his body, but thanks to Johnny Quick he realized that his power now came from his metagene. Now all he needs to do say, "Man of the Hour!" to activate his super-powers, but it still will last for an hour.
In conclusion, we can clearly see developing a Sidekick TV Series is a possibility in the CW's universe. Rex, Rick, and possibly Matthew Tyler? They could be the perfect core to a new DC superhero team up show, if you ask me.
