I agree plus there's plenty of other memorable DC villains that haven't been introduced yet as well which is hopefully a good thing in the DCEU's future:
The major DC villains we've seen so far in DCEU are Joker, Harley Quinn, Deadshot and Killer Croc (Batman), General Zod, Lex Luthor and Doomsday (Superman) and (Captain) Boomerang (The Flash).
Then there's rumoured for Suicide Squad 2 (if there is one):
Of the major rogues we still haven't seen yet are Bane, Mad Hatter, Scarecrow, Mr. Freeze, Two-Face, Penguin, The Riddler, Hugo Strange, Ventriloquist and Ra's al Ghul (Batman). Bizarro, Darkseid, Braniac, Cyborg Superman and Mettalo (Superman) plus many more from Wonder Woman, The Flash, Aquaman, Green Lantern and Cyborg.
There's (also) even superhero's that we haven't been introduced to in the DCEU yet like Batgirl, Supergirl, Green Arrow, Robin (apart from the costume in BvS), Zatara, Zatanna and Martian Manhunter.
