What’s so great about DC is that it’s full of interesting characters who can make a big impact with minimal screen time. Here are 10 side characters who completely stole DC TV shows.
1) John Diggle (Arrow)

Oliver Queen returns home in Arrow with one goal: to get rid of all the corruption in Star City. Becoming a vigilante isn’t easy, though, because Oliver’s bodyguard, John Diggle, is watching his every move. Eventually, Oliver brings Diggle into the fold, and the two of them work together with Felicity Smoak to fight crime.
Despite Team Arrow growing in every season, Diggle always finds a way to steal scenes. His argument with Oliver in Season 6 about remaining the Green Arrow, in particular, stands out as a moment that proves his value as a character.
2) Vigilante (Peacemaker)

It’s hard for anyone to one-up John Cena, especially when he’s giving his all as the anti-hero Peacemaker. Well, one character in the HBO Max series Peacemaker gives it his best shot by being a cross between Ms. Marvel and the Punisher.
Vigilante is a Peacemaker fanboy who starts following the titular character around and gets wrapped up in the fight against Project Butterfly. Where Vigilante really gets to show off, though, is in jail when he confronts White Dragon and his Nazi buddies.
3) Nina Mazursky (Creature Commandos)

James Gunn’s other DC TV project, Creature Commandos, focuses on Rick Flag Sr. and his ragtag group of monsters. While Flag and the Bride steal the spotlight for the majority of the show, Nina Mazursky delivers the show’s most tragic backstory in Episode 7.
Unlike her teammates, Nina doesn’t have a criminal background or enjoy hurting people. She just wants to help her friends, and she gets the opportunity near the end of Creature Commandos. Unfortunately, she’s not cut out to be a killer, a fact that costs her dearly.
4) Oliver Queen (Smallville)

Clark Kent’s life in Smallville, Kansas, is strange due to the existence of the Meteor Freaks, villains created by the Kryptonite within the town. However, things don’t get simpler when Clark visits Metropolis because he meets other vigilantes, including Oliver Queen, aka Green Arrow.
Oliver’s suave attitude catches Lois Lane’s attention, and the two spend plenty of time flirting. Clark dislikes Oliver at first, but he learns how impactful his rival can be as a hero and teams up with him on numerous occasions.
5) Captain Cold (The Flash)

Like Smallville, Central City creates its fair share of villains after the particle accelerator explosion in The Flash. Barry Allen’s greatest villain in the show’s early season isn’t a metahuman, though; he’s nothing more than a man with a gun that shoots ice.
Captain Cold terrorizes Team Flash time and time again, but it’s hard to root against him because of Wentworth Miller’s incredible line delivery. The Flash picks up on this and starts to make Captain Cold more of an anti-hero, even making him a big part of Legends of Tomorrow.
