Speed Force
Garrick and his wife, Joan, have guardianship of Bart Allen after Max Mercury's disappearance. 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, his speed is diminishing with time. After Bart leaves Keystone City for Los Angeles, Garrick, once again, is the city's sole guardian. After hearing news of Bart's demise, Garrick collapses with grief, consoled by Jesse Chambers.
