emerged from retirement in 1961 to meet the Silver Age Flash, Barry Allen, from a parallel world. The rest of the JSA soon joined the Flash, although their activities during the 1960s (other than their annual meeting with Earth-One's Justice League of America) were unrecorded, although it is clear that Garrick and Green Lantern (Alan Scott) were good friends. It is also established that Garrick has become a respected scientist on his Earth. Garrick was a key member of the JSA's 1970s adventures (as chronicled in All-Star Comics and Adventure Comics). Garrick also helped to launch the careers of Infinity Inc. Following the Crisis on Infinite Earths, all the parallel worlds are merged into one, and Keystone City becomes the twin city of Allen's Central City, with the two separated by a river. An updated story suggests that Keystone in this new continuity is rendered invisible and wiped from the memories of the world for many years through the actions of several supervillains. 21st Century In the early 21st century, many of Garrick's JSA cohorts have retired or died, but Garrick remains active with the latest incarnation of the group.

During the events of Infinite Crisis, Garrick states that the Speed Force is gone after a battle in which many speedsters, living and dead, wrestle Superboy-Prime into the Speed Force and disappear. Garrick is left behind on Earth by the other speedsters when he reaches his speed limit and cannot follow. Bart Allen returns, aged several years, having absorbed the entire Speed Force during his pursuit of the escaped Superboy-Prime. Garrick claims that without the Speed Force, his own power is less than before: like Wally West in the Crisis on Infinite Earths aftermath, he can only run close to the speed of sound. He also states that, as the Speed Force is no longer retarding his aging,
