After that explosive season five finale, Stephen Amell recently confirmed that Manu Bennett will be back as Slade Wilson aka Deathstroke.

"I can report that Manu Bennett is back to being a part of the show," Amell revealed. "I think we will see him multiple times this year, which is awesome."

On top of Deathstroke's return, Amell also teased that a character last seen all the way back in the first season will be coming back this year.

Arrow will return to The CW in the US this autumn. In the UK, the DC TV series airs on Sky 1.
