In a future where Iris was killed by Savitar, Barry defeated and imprisoned him in the Speed Force, gave up his Flash identity and disbanded Team Flash; then, he retired to an abandoned S.T.A.R. Labs.
Barry Allen became The Flash after being hit by a lightning during the S.T.A.R. Labs' particle accelerator explosion. He was a member of Team Flash and protected Central City from crime and supervillains. He also became the lover of Iris West.
At some point in time, after causing and undoing the Flashpoint, an evil speedster called Savitar came to Central City and confronted Barry several times over the months: during a confront, he casually was sent to the future and discovered Iris' death at the hands of Savitar. In May 2017, the vision came true as Savitar killed Iris.
This event put in motion a chain of events that led to Wally becoming comatose after a confront with Savitar, Joe West, Cisco losing his arms and Joe West estranging himself from Barry after losing both his children.
Some time after Iris' death, Barry created multiple time remnants to help him defeat Savitar but the evil speedster killed them except for one of them who went evil and, later, became Savitar himself, creating a time loop. As Barry battled Savitar one last time, he managed to finally defeat his mortal enemy, imprisoning him in a Speed Force cage thanks to a Speed Force bazooka which was build by the scientist Tracy Brand. Then, Barry officially disbanded Team Flash and retired into the S.T.A.R. Labs which was shut down, letting Central City being totally controlled by the supervillains, like Mirror Master and the Top.
The Return of the Flash
In 2024, a past version of Barry came to this future in order to get information to defeat Savitar in the past. He reached his future counterpart who told him about the events that followed Iris' death and explained him that he didn't ever manage to discover Savitar's real identity. Barry was accused by his past self to have given up on everyone he loved but the future self explained him that the grief about Iris' loss was too strong to overcome.
Future Barry refused to help his past self regain control of the city and left him and the other Team Flash members confront the menace of Mirror Master and the Top. Later, after seeing his past self being almost defeated by Top's powers, Barry finally decide to resume his duty as the Flash and arrived on the battlefiled to aid past Barry in taking dow nthe supervillains.
