Deathstroke (Slade Wilson), played by Manu Bennett may have a possible appearance in Arrow. His character played a big role in the first two seasons ofArrow but last we heard from him he is in A.R.G.U.S the supermax prison in Lian Yu Island.
Stephen Amell gives us his opinion on Manu and his character. “Manu is a character, and Manu played a great character,” Stephen Amell said during a panel at the Heroes and Villains Fan Fest in New Jersey this weekend. “And I really honest think that Arrow has been missing something since he hasn’t been around. I really do. He was a transformative villain. I would really love it if Deathstroke could keep being a part of the Arrow universe.”
