Supergirl should have Lobo at some point, there is a lack of good alien villians on that show that are not dead.

My pick for Arrow would be a full costumed Wildcat.

Flash should include the future Flash who is an alternate version of Barry who lost everything in his life and is a speedster with vengeance. This character whould be good sometime in S3 for Barry to get over how he had to get rid of the Flashpoint world.

Legends should have Booster Gold, but get rid of him after one episode cause he is too annoying for my sanity to take after that.

Supergirl should also have Guardian and Superboy during this Project Cadmus arc.
