Hourman src

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. He became a valued member of the Justice Society and the All-Star Squadron.

Man of the Hour

Raised in upstate New York, young Rex Tyler found an affinity for the sciences, particularly those areas involving chemistry and biology. In 1919, as a boy in Ithaca, New York, he was visited by his future self who gave the child version an hourglass and told him to keep it, saying that he would ask for it back in his final hour.[1] Working his way through college, he landed a job researching vitamins and hormone supplements at Bannerman Chemical. A series of discoveries and accidents led him to the "miraculous vitamin" or Miraclo. He found that concentrated doses of that "vitamin" gave a strength and vigor to laboratory mice several times that of normal. Taking a dose, Rex found that his strength, vitality and speed increased to super-human levels. However, the human body could only process the Miraclo for one hour at a time, after which the subject was left weakened and returned to human strength levels.

Keeping his discovery of Miraclo a secret, Tyler decided that human trials could be limited to the only subject he could trust... himself. Feeling that the Miraclo-induced abilities should be used for good purposes, he decided to use the abilities to help those who needed it. His first mission came as a result of Tyler's placing an ad stating that "The Man of The Hour" would help those that needed it. Tracking down one respondent to the ad, he aided a housewife whose husband was falling in with the wrong crowd, and stopped a robbery. Using a costume he found in an abandoned costume shop, he started to adventure as The Hour-Man (later dropping the hyphen).


Nearly eleven months later, after becoming noted for helping the "common man" and battling weird menaces, Hourman became a charter member of the Justice Society of America. Faced with heroes that used magic, flew and wielded mystical rings, Hourman further strengthened his Miraclo and this led to it slowly becoming addictive. The drug would make him anxious and talkative when he used it.[2]

During one case, Tyler's heart gave out, his system poisoned with the toxic side effects of Miraclo. Doctor Fate, through mystical means, cleansed Hourman, and after the case, he retired from active crime fighting, taking a leave of absence from the JSA. During that final case, he was irradiated with chronal energies that slowed his aging later in life.[3]


Despite diminished use and refinement of Miraclo, Rex would abandon his Hourman identity in 1943, the physical and emotional strain of the drug proving too great even for occasional use. He continued to assist the JSA on occasion, but after 1945, he devoted his time and effort to biochemical advances. Using independent patent royalties, he purchased Bannerman Chemical and renamed it Tyler Chemical Company (later TylerCo). With branch labs around the US, Rex Tyler had little time to relive his wartime glory days.

At some point, Rex began to take up company with Wendi Harris, an up-and-coming stage actress. During one of their dates, they ran across The Psycho-Pirate, a modern criminal whose mentor was an old Justice Society foe. Along with a recently empowered Doctor Fate, the duo defeated the villain and Rex worked up the courage to ask Wendi to marry him, despite the twenty-some odd year difference in their ages. Wendi agreed, and they were soon blessed with a son, Richard. To Rex's consternation, Rick showed no interest in things academic, instead leaning towards sports and art. This was a major source of friction between father and son for most of their lives.

Seeing that one day his son might want to take up the cause and fight for justice, Rex began secretly tailoring the Miraclo formula using genetic engineering for use by Rick or his descendants. He forbade Rick from taking up the Miraclo Pill, citing its side-effects. However, during the Crisis on Infinite Earths, to save the lives of people trapped during one of the time-storms, Rick took the pills and began to adventure as Hourman as his father and his fellow Justice Society members were caught in a limbo-like dimension.

Reports of My Death

 Main article: Zero Hour

He was seemingly killed along with other Golden Agers fighting a time traveling villain named Extant during the events of Zero Hour. He was recently rescued from that fate by the third Hourman who took his place in that battle. Rex now lives in semi-retirement with his wife Wendi.


  • Unique Physiology: sometimes Rex could reinforce residues of the Miraclo pill contained in his body and access its effects, once by using a black light,[4] other time by reciting the mantra "Man of the Hour".[5]
  • Enhanced Immune System:[2] the effects evidently persist even after Miraclo wears off.



  • 60 Minute Time Limit: After a 60 minute time period, the "AQP" burns itself out, and the waste toxins generated need to be eliminated in the bloodstream over about a 24 hour period.

Other Characteristics


  • Miraclo: Hourman derives all his superhuman abilities from the "miracle vitamin" Miraclo. The active ingredient is a special form of phosphorus, which bonds temporarily with the ATP in muscle cells to create a "Adenosine Quad-Phosphate" which energizes the cells.


  • Tear Gas Ring: During his early adventures, Hourman used a ring capable of emitting a tear gas to overcome his foes.[8]

  • Although this character was originally introduced during DC's Earth-Two era of publication, their existence following the events of the 1985–86 limited series Crisis on Infinite Earths remains intact. However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and no longer apply.
  • Rex was 6 years old in 1919.[9] Combined with his birthday from the 1976 Super DC Calendar, this would make his birthdate November 5th, 1913.
  • Rex has gone by a few nicknames during his Golden Age career such as Tick-Tock and The Man of The Hour.
  • Recently, it was discovered that Venom, a super-steroid compound was derivative of Miraclo, and the street drug A39, which was a form of Venom, gave the second Doctor Mid-Nite his heightened strength and night vision.
  • Rex and Rick both wore an hourglass around their necks given to them by the Hourman Android. It was filled with energized tachyons, time in its most basic form.
