Julio Mendez was a captain in the Central City Police Department.

When the Flash went back in time to save his mother from being killed by the Reverse Flash, he created a new timeline of events that would have happened if his mother had not been killed, later dubbed "Flashpoint."

In this new reality, one of the changes was that Barry's boss at the police station was not Captain Singh but instead Captain Mendez.

Capt. Mendez was later erased from the timeline when the Flash tried to undo his actions by having the Reverse Flash kill his mother again.[1]
