2) Deathstroke
For ages it was rumoured that Scott (son of Clint) Eastwood’s character in Suicide Squad would be someone huge. The two big theories were that he was either Nightwing or Deathstroke. Sadly, neither turned out to be true – but we still really want to see Slade Wilson appear in the sequel. Fans already know how awesome the guy can be in a live-action capacity from his status as the best villain on Arrow (as played by Manu Bennett).
Known as Deathstroke the Terminator, it won’t surprise you to know that the character is a damn fine assassin and mercenary who, unlike Deadshot, possesses super powers – more specifically, super strength, agility, endurance and intelligence. Seeing as his Marvel counterpart Deadpool (Wade Wilson rather than Slade) has already got his own film, it’s about time this fan favourite was brought to the big screen, too.
