[2] Rex Tyler made his live action debut in the season one finale of The CW series Legends of Tomorrow portrayed by Patrick J. Adams.
Both Rex and Rick Tyler also appear in the DC Universe series Stargirl portrayed by Lou Ferrigno Jr. and Cameron Gellman respectively.
The original Hourman is Rex Tyler who appeared in the Golden Age of Comic Books and is a founding member of the Justice Society of America.
After serving for a few years as a member of Infinity, Inc., a team composed largely of other JSA-member children, Rick began to grow addicted to Miraclo just as his father did.
He spent many years after leaving the group critically ill until Amazo, posing as a future incarnation of the android Hourman, cured him of his Miraclo addiction.
Having conquered his personal demons and regaining his health, Rick joined the JSA in its incarnation as a small band of freedom fighters during the "Stealing Thunder" arc.
As a second gift, Rick could visit with his father in an otherworldly dimension called the Timepoint, frozen in time, just before Rex's death.
Originally possessing the time-manipulating cosmic artifact known as the Worlogog, he divested himself of most of its power at the suggestion of Snapper Carr and went about learning to be human.
As noted above, he is believed to have been destroyed at the hands of Extant in Rex's place, although the time-traveler Rip Hunter mentioned that his actions would leave him inactive for a relative year, indicating his probable return.
Most obvious are the superhuman strength, durability, increased resistance to physical damage (to the extent of being impervious to small arms fire) and speed enhancements.
"Tyler" is often simply called an android, but is actually an intelligent machine colony (possibly a form of nanotechnology) created by Tylerco in the far future.
