The League of Extraordinary Gentlemen series by Alan Moore and Kevin O'Neill covered plenty of characters and subjects across multiple volumes, shifting across time and space to focus on many of fiction's most iconic characters. However, one character frequently served as the emotional linchpin of the series -- and should continue to do so going forward in the upcoming film adaptation of the story.
Mina Murray is the heart of Moore and O'Neill's love letter to Victorian era characters and arguably the closest thing the expansive and epic series has to a central protagonist. If the story is coming back to the big screen, she deserves to be the film's primary focus.
The original volume of League of Extraordinary Gentlemen largely focuses on Mina's perspective as she ends up meeting strange and unique figures from around the world. Taking place after the events of Dracula, Mina is introduced as a divorced and bitter woman, recruited by Campion Bond to the League thanks to her experience with the supernatural. Mina serves as the reader's surrogate character, journeying with her across the world as the rest of the team is recruited. Despite lacking the abilities or experience of her unlikely teammates, she quickly establishes herself as something of a leader to the group.
She forged a bond with Hyde and developed a romance with Quatermain, but ventured off on her own after the team dissolved at the conclusion of Volume II. This was only the beginning for Mina however, as she eventually found the Pool of Fire alongside Quatermain and the pair were rendered immortal -- giving them the ability to take part in events across the 20th and 21st century. During that time, Mina faced off with a truly despicable take on James Bond in the 1950s, fought back against the machinations of Aleister Crowley, and dealt with the chaos caused by a Harry Potter-tinted Antichrist.
Mina's entire arc sees her transition from an innocent woman of the Victorian era into an action hero of a new age. Mina is characterized throughout the story as someone who has experienced true darkness in her life and finds herself undisturbed by the darker sides of humanity as a result. She's openly sexual but relentlessly defiant, fighting back against aggressors with more fervor and skill as the series evolved. She grows from someone who struggles to survive the bizarre to someone who thrives while confronting it.
It would be a large improvement on the version of the character that appeared in the 2003 film adaptation. Played by Peta Wilson, Mina was not treated as the leader of the group in this incarnation -- and retained vampire qualities along with a quasi-romantic plot line with the traitorous Dorian Gray. That version of Mina lacked any of the growth that defined her comic book counterpart. Any new adaptation should look to the source material's depiction of Mina for inspiration. She is in many ways at the heart of the narrative and arguably achieved the most character growth.
