Barry Allen , who was formally a forensic scientist of central city polic department which appears first In Arrow TV series for Introduce .after somedays an accident which creator Harrison Wells as Edward Thawne at Star Lab Convert him into The Flash.He became THE FASTEST MAN ALIVE .The Flash named given by Iris west , Barry Allen 's girlfriend but if you observe The Flash named given by OLIVER QUEEN Who is the protector of starling city .Many times Arrow and The Flash Crossover make more excitement for both TV series.If Anybody want something more fun They should watch The Flash TV series as well as Arrow Supergirl and Legends of Tomorrow .All four TV series made a universe which is called ARROWVERSE .All season of The Flash series is very watchable.So I love this TV series
