The crossover is currently active on Tumblr and YouTube due to the official canon crossover episode that premiered on March 28, 2016[1].

The most popular form of fanworks are gif-sets made to look like scenes where characters from the different shows are interacting and fanvids. Other fanart (such as actual art and picspams) and fanfics have also appeared.

Some of the ships between the shows are often compared to each other or fans often show parallels between them[2][3].



The name "SuperFlash" is also used as a pairing name for the ship of the titular characters: Kara/Barry. Prior to that ship and crossover, it was sometimes used for Clark/Barry pairing.


See individual pairing pages for more fanworks.
