Scott Eastwood

He has the lowest of all low chances. However, Scott Eastwood could be brought back to portray the mercenary. We already know that he has the skills as a soldier, even if he didn’t actually display them in Suicide Squad. But I found it peculiar that nobody mentioned his death. So maybe he didn’t die. Maybe he was severely wounded, but still alive and retrieved by the army.

It isn’t too hard to imagine that Amanda Waller would come up with a super-soldier program and that GQ, as we previously knew him, would become Deathstroke. This, to a certain degree, would also explain his presence in the Justice League movie. Maybe it is then when he turns bad? Who knows?

As said, there are very few chances for Scott Eastwood to portray the mercenary. However, few is more than none. And I can bet that he can make a good impression as this character.
