Every Villain The Arrowverse Has Teased But Not Used

Green Lantern is yet again another DC mainstay who is yet to appear in the Arrowverse, with John Diggle's recent appearances suggesting that the Emerald Knight is still some ways off from making his small-screen live action bow.

If the powers that be at DC and Warner Bros. TV saw it fit to give Green Lantern (especially Hal Jordan) an Arrowverse appearance, having him go up against Carol Ferris/Star Sapphire would be a good place to start.

The second season of Arrow and first season of The Flash each showcased Ferris Airline and a Ferris Air Testing Facility, respectively. Most comics fans will know that Hal and Carol's relationship had its foundation built on the facility before they both become superpowered beings.

Initially, it seemed like the Arrowverse could not sustain a Green Lantern series or even appearance due to the character's visually complex abilities, but series such as Superman & Lois and Stargirl have proven that having a character such as Lantern and indeed Star Sapphire is at least plausible.
