"You go back to the League -- I did an episode of 'Legends' last week -- and I look exactly the same in 1975 but you see he's not as confident and doesn't have such an agenda forty years ago as he does now," McDonough said. "So it's fun to play the different times, you know? Going back in time with 'Legends,' and 'The Flash' -- with 'The Flash,' I'm just this crazy, fun, enjoy everything while I kill everybody type of character. It's just nuts."
McDonough also spoke to the other big bads that have either plagued or will plague the CW's "Arrow"-verse series, saying: "I'm enjoying the power that I have because it's my time," said McDonough of Damien's dominance. "It's not Savage's time, it's not Ra's al Ghul's time; it's Damien Darhk's time."
"Arrow" airs on the CW on Wednesday nights. "Legends of Tomorrow" arrives on the scene in 2016.
