As the Season 5 premiere showed, it's Felicity Smoak (Emily Bett Rickards) who is pushing hard for Oliver Queen (Stephen Amell) to assemble a new superhero support system. With Thea (Willa Holland) hanging up the Speedy costume, Diggle (David Ramsey) returned to the army and Laurel (Katie Cassidy) murdered by Damien Darhk, there's no one left to fight alongside Oliver on the streets of Star City.That's where Season 5's new crop of crime-fighting heroes comes in. The premiere saw the introduction of Wild Dog (Rick Gonzalez) and the beginning stages of Curtis Holt's (Echo Kellum) transition into Mr. Terrific. Viewers will also see Evelyn Sharp (Madison McLaughlin) join the new Team Arrow as her new alter-ego, Artemis, in the second episode of the season, appropriately titled "The Recruits.""You really get to see the juxtaposition of how this new Team Arrow kind of acts against the old Team Arrow," Kellum told IGN on the set of Arrow. "What's cool is that you'll see some riffs and some issues surmount from that. Some of our members are more reckless than others. They're still trying to figure it out. Oliver is really concentrated on making sure that these guys are really up to snuff and can handle it, because he doesn't want to see another Laurel situation happen, where somebody that's on his team gets killed in the line of fire because he didn't train them right."While Oliver was holding everything in stasis hoping for things to go back to the way they were before the catastrophic events at the end of Season 4, Felicity has been the person pushing him to look forward. She and Oliver are the only two members of the original team who remain, as the pair are now working together as platonic partners instead of romantic ones."She definitely wants the team back on the road, whether that includes part of the old team or not. Obviously the old team is preferable, but also getting back out there and setting out what they were designed to do in the first place," Rickards said. "For her and Oliver, they're basing their relationship now on a partnership and what they work towards together. If they don't have a common goal, and they're not working towards that, not only are they the only two left, but they're working towards different things. Protecting the city was always the first thing, and if we're here to protect the city then Felicity thinks this is the best way to do it, getting the new team together."The new team is coming together just in time for a new crop of villains to threaten Star City. Beyond central bad guy Prometheus , there's Chad Coleman's Tobias Church wreaking havoc, plus the promise of other rogues popping up throughout the season. Though Oliver's quest is to fix the criminal problems in Star City, simply having a designated vigilante causes a city to be targeted more."Oliver Queen's presence invites challenge, right?" reflected Ramsey. "The city in many ways has become more of a challenging place to live in because his presence in it. He's opened the door to other vigilantes. What happened with the Flash event and now there are advanced humans on the earth, I think all that has kind of changed the tone of what Star City was."Ramsey sees a positive impact from all of the original Team Arrow's crime fighting, though, that will hopefully translate now that the new team is coming together. "There's probably more hope in the city than there ever was before, and I think that's directly due to Oliver Queen's presence," he said.But even the cast doesn't think all hope is lost for the original Team Arrow -- or OTA, as fans refer to it -- to reunite. "I think there is some intersection there for sure," said Kellum. "I mean, it's all the Arrowverse. They definitely mix it up with different characters, whether it'd be Lance or Thea or Diggle. It's just going to take some time to see exactly where the OTA or the Old Team Arrow could come back into the forefront, if that even happens, because I'm not even sure where it's all going as of right now. I'm pretty sure you'll see the old team back together."
