The Arrowverse is certainly no stranger to crossovers, and if the blockbuster ratings from last fall's "Invasion!" event are any indication, fans will be seeing plenty more. A "Flash"/"Supergirl" crossover is already announced for this spring, but another meeting of The CW's original dynamic duo will happen well before that.

On Twitter, he posted an image of the Fastest Man Alive speeding through Captain Singh's office in the Central City Police Department.

The Flash has a lot on his plate this season, as Barry races to prevent the death of the Iris West (Candice Patton).
