The Star City in the story will change, not only Arrow took office as the new mayor, but he also implemented a law as vigilante Green Arrow. Killing is now legally allowed. What does this mean for season 5?

After Thea (Willa Holland) quit the team to focus on herself and Diggle (David Ramsey) quit to re-enlist, the team has been feeling a little hollow. When the season 5 begins, Oliver and Felicity (Emily Bett Rickard) try to keep things going on their own, but felicity knew that this is not going to last forever because oliver split his time as Mayor of Star City.

She already got some new recruits like Curtis (recently promoted series regular Echo Kellum), vigilante wannabe Wild Dog (Rick Gonzalez) and former Black Canary copycat Evelyn Sharp (Madison McLaughlin) as she starts her journey to become her DC comics alter ego Artemis.

Even though Laurel (Katie Cassidy) was killed in season 4. This doesn't mean that she will be gone the entire show. "She's definitely not gone," executive producer Wendy Mericle says.

The new villains are the gangster Tobias Church (Chad L. Coleman), who is looking to take over Star City's criminal underworld. And the second is a character with no DC Comics origins. "He's a new character. He's our big bad for the year," executive producer Marc Guggenheim says. "We call him Prometheus."

It's not the Grant Morrison-Howard Porter Prometheus from the Justice League. He's a new character that fits in with the theme of legacy for this season. He's pretty badass and mean."
