By the time "Arrow" Season 5 rolls around, there will be a new antagonist in town -- and one Mr. Oliver Queen set him down his dark path towards villainy.
Speaking to TVGuide, executive producer Wendy Mericle revealed a few new details about this new Big Bad, calling him "somebody Oliver unwittingly created in Season 1 when he was a killer in a hood. This guy is going to be collateral damage who lost someone to the Hood and [has] spent the last several years training and plotting for revenge. He will be a true dark mirror to Oliver Queen."
Mericle also touched on Black Canary's death. While she couldn't reveal too many details about how it will affect Season 5, she teased, "I can't say too much about that. I can say with confidence that, in Season 5, our decision will make more sense... even to the fans who were really vehemently opposed to it." She also revealed that viewers will learn what Laurel said to Oliver on her deathbed in the season premiere.
As to whether or not Katie Cassidy's Black Canary could ever appear on "DC's Legends of Tomorrow," executive producer Marc Guggenheim said, "No, that conflicts with other plans we have... he said, intentionally misleading and hopefully teasing."
Mericle also offered a few additional details about Season 5. "We will be doing a real origin story for Mr. Terrific in Season 5," she revealed. "When we come back in Season 5, [Star City] is overrun with crime."
Those won't be the only new aspects of "Arrow" next season. The team will also get a new bunker, once which appears to have multiple levels. "We wanted to have different ways to enter and exit it on a much bigger scale, since we have more characters coming in and out," production designer Richard Hudolin explained.
