Justice League: 10 Ways Deathstroke Could Appear In The DCEU

Of course, there's no actual confirmation that Deathstroke is actually in Justice League at all. We just have a single video from Ben Affleck to go on, and what other major DC is Affleck intimately involved with that would much more easily fit in a classic rogue over Justice League?

Yup, there's every possibility that the Justice League connection doesn't exist and that this is in fact exclusively linked to the Affleck produced-directed-written-starring The Batman. That'd explain why he's the one sharing this behind-the-scenes image - it's his movie - and it's certainly conceivable Affleck would use the set of Snyder's film for a costume test of his movie's big bad. Why he's revealing it so early (The Batman still doesn't have a set release date) is unclear, although it may just be to get ahead of the internet leak brigade.

On that note, I should probably mention that this notion has been corroborated by Umburto Gonzalez in a "scoop" for The Wrap, but based on how simple the story is and its timing alongside the Affleck reveal, that one seems pretty suspect; any "source" could make that claim, so it's still speculation for now.
