User blog comment:Rafe Adler/What character would you like to see appear in the Arrowverse/@comment-4588264-20151115010524

Honestly I'd love to see a crossover between Arrow, Flash and Supergirl from the TV show. They could introduce so much more hero mythology with that (Superman) and I think she would fit right into the Arrowverse, since they are sort of connected anyway with the same creators. I'd also love to see Vixen from the web series if ever possible. Another crossover that's the most unlikely is with Gotham, (perhaps James Gordon and the GCPD from the future) but I'd love to see it happen if they could.
