King Turtle brings his army from the future to conquer Central City in the present. He also brings the future version of Barry, from whom Turtle has already stolen his speed, now he wants to steal the speed of the younger Barry in his plot to stop time from moving forward. When the younger Barry wants to fight back, the older Barry tells him he cannot or he will create a time paradox, and that his only option is to flee so King Turtle cannot take his power.
