Characters come and go all the time once they've lost their purpose, but what about those characters that are indefinitely kept around, even when they've all but disappeared into the background?
They're criminally underused, only sticking around to be important in an episode to further some main character's pain, like Thea is to Oliver on Arrow.
Some are written to be a plot device, while some just stay around because they may not have a story now, but there is a possibility for one in the future. Have any characters in mind? Here's our list.
Iris West - The Flash
Iris had more screen time on Earth-2 than the original. She's a badass reporter, who could prove to be a viable asset for Team Flash using her investigative journalism skills, but instead, she's used to further Joe or Barry's story? She's barely even had a scene with her newly discovered brother, Wally. Why can't Iris be a strong character on her own, and not just used as Barry's love interest?
Thea Queen - Arrow
Thea Queen has been shoved into the background since season one. She was used to further Oliver's manpain, Roy's, even her father Malcolm's. Who, by the way, brainwashed her and made her murder Sara Lance, a long time family friend. She watched her mother be murdered right in front of her. Somehow along the way, she became Speedy, after growing tired of all of the men taking advantage of her, but even the bloodlust she suffered from was used to further Oliver's story, instead of her own. When will Thea Queen get the story she rightfully deserves?
Mona Vanderwaal - Pretty Little Liars
Remember when Mona had the potential to be truly crazy? She tormented the girls for years, but became their strongest ally when Charlotte took over the game, only to be shoved aside. She wasn't given a chance to redeem herself, even though the writers referred to her as the "fifth liar" and her knowledge was little in order to keep the mystery going. Mona had the chance to prove herself so many times, but the opportunity was never afforded to her, because of the girls' mistrust.
Isabelle Lightwood - Shadowhunters
In the books, Izzy was a sassy hunter. Surprisingly, the show got her personality right. She's very comfortable with herself and her sexuality, and she can be a fierce competitor. Unfortunately, even her family writes her off. Izzy isn't as good as Alec, she's not as sophisticated, and her interactions with people that are considered "not pure" are frowned upon. Hopefully, when season two premieres, Izzy's glory as a shadowhunter will be explored, as well as her relationship with Simon, giving her some time to shine among her comrades.
Melinda May - Agents of S.H.I.E.L.D.
Agent May is hailed by her collegues as "The Cavalry." Or she was. She was the best fighter on the team, only rivaled by Bobbi Morse, who is no longer on the show, but still, May does not get her own story. Her current story only peaks when it's related to her ex-husband, or putting Coulson in his place. Daisy has taken over as the skilled fighter because of her Inhuman powers, but who's the one that trained her?
Winn Schott - Supergirl
Winn has the potential to be the Felicity Smoak of Team Supergirl. He's a skilled hacker, has a great sense of personality, and has a dark past with his father, "Toyman." But after the love triangle was written away and Kara dismissed Winn as anything more than a friend, he's all but vanished and his usefulness hasn't been explored. Could you imagine Winn as a DEO agent? He has the ability to do so much more than work as Cat Grant's personal programmer.
