The Flash must call upon his allies when a powerful alien threat arrives on Earth under mysterious circumstances, pushing the team to its limits in a desperate battle to save the world.

Barry and Team Flash are caught up in a conflict between the Speed Force and other forces of nature. As old friends say goodbye, the city is besieged by an army of speedsters from the future.

A brilliant physician goes down a dark path in his desire to defy the laws of nature, turning him against Team Flash and threatening Central City with a monstrous new villain: Bloodwork.

As Barry and Iris cope with the arrival of their own daughter from the future, a killer attempts to eradicate all metahumans from Central City.

Barry returns from the Speed Force a changed man, and must rediscover his old life and his family in order to take on a super-intelligent new foe: Clifford DeVoe, whose plans are always two steps ahead of Team Flash.

Barry's decision to alter the past has long-term consequences, opening the door to a new enemy who calls himself the "God of Speed" -- while those close to him struggle with their own emerging powers.

After saving Central City from a massive black hole, Barry discovers that new threats are pouring in from a parallel world -- sent by a super-villain who consumes the speed force. But a fellow speedster also arrives to help the Flash try and stop Zoom.

When he acquires the power of super-speed, police forensic scientist Barry Allen has a new way to protect Central City from its super-powered criminals -- and to search for the person who killed his mother.
