Arrow: What We Leave Behind Photos Released

Prometheus has been a thorn in Oliver's side this season, but in "What We Leave Behind" he will be much more than that.

In the newest episode of Arrow, the team will face off against Prometheus after he attempts to take out Curtis. The newest photos from the episode reveal a throwdown between Arrow, Diggle, Wild Dog, and Prometheus, and hopefully, behind the scenes, Team Arrow can finally start to peel back just who the new villain is.

"He has a very personal grudge and axe to grind with Oliver and he's going to come at him in a really interesting, sociopathic kind of way," executive producer Wendy Mericle told IGN.

You can view the newest images from the show in the gallery, and if you want to know more about where Prometheus originated from, you can head here. The official description is listed below.

PROMETHEUS MAKES A DEADLY MOVE AGAINST OLIVER AND THE TEAM — After Prometheus attacks Curtis (Echo Kellum), Oliver (Stephen Amell) realizes Prometheus knows all of Team Arrow's secret identities and is planning to come for them one by one. Felicity (Emily Bett Rickards) and Detective Malone (guest star Tyler Ritter) discover a clue that links Prometheus to Oliver's past.

Antonio Negret directed the episode written by Wendy Mericle & Beth Schwartz.

Arrow airs on Wednesday nights at 8 p.m. ET/PT on The CW. "What We Leave Behind" will debut on December 7, 2016.
