Hourman II: Rick Tyler
When Rick had grown, he also decided to adopt the guise of Hourman (II). (Infinity, Inc. #20) But just when Rick could have used Rex's guidance most, the original Hourman disappeared with the rest of the JSA into Limbo. (Last Days of the JSA) Rick Tyler has suffered much in his brief time as a hero. He became Hourman II during the Crisis and soon joined Infinity, Inc. (#31) His tenure with Infinity was short-lived because of the onset of his own illness and addiction from the use of Miraclo.
Rex was reunited with his son after the JSA's return from Limbo (Armageddon: Inferno #3-4), only to discover that Rick had contracted leukemia, apparently the result of the Miraclo. Rex's old friend Johnny Chambers (Johnny Quick) later helped Rex and Rick learn to tap their superhuman strength and endurance without the use of Miraclo. This brought them closer together, but for too short a time because Rex soon died at the hands of Extant during the Zero Hour. (Zero Hour #3) Further tragedy struck when Rick's love interest, Beth Chapel (Dr. Midnight) was slain by Eclipso. (Eclipso #13)
