Cyborg connection

While the best chances are for Deathstroke to be connected in some way only to Batman, maybe we should take a look at the comics. There, Deathstroke is the most well-known antagonist for the Teen Titans. And since Cyborg is (in the comics, of course) a member of the Teen Titans"¦

I don't really know how this could work out. But the thing is that Cyborg needs some development. We need to know just how powerful he is and why he is one of the founding members of DCEU's Justice League.

So a subplot of the movie could see him taking on Deathstroke. Although this doesn't actually explain the villain's presence in the Flying Fox.

Anyway, if a Teen Titans movie were to replace the planned Cyborg flick, maybe it wouldn't hurt for their antagonist to be introduced earlier in the timeline. In this way, we'd get an idea not just how powerful Cyborg is, but also how powerful Deathstroke can be. And this is a win-win situation.
