It’s been a trying year for Arrow. While the DC series starring Stephen Amell as the Green Arrow faltered in its fourth season, the show is looking to regain fans in a seriously promising Season 5, airing October 5 on the CW. At San Diego Comic-Con, the show’s actors and producers attended the show’s panel by teasing some of the season’s principal stories — namely, the Green Arrow’s role as mentor to a new Team Arrow — and the season’s antagonist, Prometheus. So what’s in store for Arrow Season 5? Definitely you tuning back into the show again.

1. Prometheus, the new season’s villain.

At the end of the trailer (embedded below) is Prometheus, a sword-wielding hooded figure that’s after the Green Arrow, though executive producer Marc Guggenheim said it’s not the Grant Morrison creation most fans are familiar with. Rather, it’s a new character “who fits into the idea of legacy that’s going to be driving all of our characters this year,” Guggeinheim said at the panel.

2. A new Team Arrow that Green Arrow whips into fighting form.

With Willa Holland’s Speedy and David Ramsey’s John Diggle retired (likely temporary) and Katie Cassidy’s Black Canary deceased, Oliver recruits new members for Team Arrow since no man can go on a crusade against crime alone. Even Batman needs help.

Wild Dog, Artemis, and Mister Terrific — a civilian names Rene Ramirez, Evelyn Sharpe (returning from Season 4), and promoted series regular Curtis Holt — join the ranks of Team Arrow, with harsh training from Oliver Queen himself. Becoming a superhero is no vacation, and it’ll be Oliver’s biggest challenge to turn heroes out of complete zeroes.

Interestingly, Oliver’s harsh teachings will echo the new season’s flashbacks: His time in the mob.

3. The season’s flashbacks focus on Oliver’s time with the Russian mob.

This is not a new development, but the trailer shows a little preview of Oliver’s time with the Russian mob, an experience that only added to the Arrow’s arsenal of brutality.

Structurally, the flashbacks in Season 5 will let Arrow close off the flashbacks, which they said will allow them to start anew in Season 6.

4. The brief return of Laurel Lance.

Guggenheim said Katie Cassidy is “not gone” from the Arrowverse, with a contract allowing her to appear in all the DC TV shows including Legends of Tomorrow. And she’s definitely going to be in the season’s first episode, most likely in a flashback form or other.

5. The 100th episode will be Part 2 of THE DC television crossover.

Without a formal announcement, the four-way crossover between Arrow, The Flash, Legends of Tomorrow, and Supergirl will be a three-parter, with Part 2 being the landmark 100th episode of Arrow. Appropriate that the show that started this corner of the DC Universe gets to be directly involved with a seriously gargantuan TV crossover.

6. A changed Diggle (No word on Flashpoint, strangely)

The previous panel for The Flash indicated John Ramsey’s Diggle would be altered by Flashpoint, but during the Arrow panel Ramsey only had this to say about his character (via ComicBook:

“He’s with the Special Forces handling some stuff over there. He misses the team but he’s still dealing with the tragic death of Black Canary and why he pulled the trigger on killing his brother … [He is] still conflicted about the events of Season 5.”

Arrow returns to the CW on October 5.
