Before the Arrowverse franchise, there was "The Cape", a 1-season origin story of a cop, rescued by carny folk who teach him their tricks of acrobatics & trickery as he develops a Batman-like persona in pursuit of the supervillain who everyone (including his own family) believes killed him. I loved this show, was disappointed it didn't go past 1 season.
