Flash Vol. 1 #159

The Flash calls it quits! Luckily, Kid Flash rushes in. The Flash's Final Fling! On Earth-2, police forensics scientist, Barry Allen, and Kid Flash pay a visit to Doctor Charles McNider. Feeling that Central City no longer gives him the accolades and appreciation he deserves, Allen has foresworn his career as the Flash. As Allen was preparing to leave Central City forever, Kid Flash abducted him, and brought Allen to Earth-2. Under hypnosis, Allen reveals that chronal officer Petar Thrant, from the year 3780, came to him, and mesmerized him into retiring his Flash identity. It seems a criminal from Thrant's time, Frand Mattar, had planted an explosive device in Central City. Fearing the Flash's super-speed vibrations might trigger the bomb,Thrant came back in time to "convince" Allen not to use his powers anymore. McNider's offer to assist the Scarlet Speedsters, in his guise as Doctor Mid-Nite, is rebuffed. Allen wants to handle this case personally, with only Kid Flash at his side.
