There's a long history of media adaptations of superheroes having an impact on the source material that inspired them. That's how characters like Jimmy Olsen, Firestar and Harley Quinn made the transition to their respective comics universes. One of the most recent and mainstream tweaks came with the way Negasonic Teenage Warhead and Yukio appeared in Fox's Deadpool films.

There's a long history of movie and TV adaptations of comics taking some liberties with iconic characters, but, for the most part, their life intact. However, as seen with Negasonic Teenage Warhead and Yukio, live-action iterations can sometimes stray away from their inspirations. So, how did the lovely couple differ from the comics in their big screen appearances?

THE MOVIE VERSIONS

Brianna Hildebrand as Negasonic Teenage Warhead

Negasonic Teenage Warhead appears in the first Deadpool film, played by Brianna Hildebrand. She's a young member of the X-Men, working with Colossus who ends up alongside the massive mutant on a mission to bring in Deadpool when he leaves a path of destruction on his hunt for Francis, the scientist who gave him his powers. Negasonic ended up forming something of a strange friendship with Deadpool, with the pair snarking at each other constantly. Eventually, Negasonic and Colossus come to help Deadpool save Vanessa from Francis.

She returned in Deadpool 2 with a new costume, a new hairstyle, and a new romantic partner: Yukio, played by Shiori Kutsuna. The pair actually quietly made history with the superhero film, becoming the first openly LGBT relationship to feature heavily in a superhero film. They play a similar role here as Negasonic did in the first film, mainly serving as X-Men and allies of Deadpool. Yukio is portrayed as a cheerful and friendly member of the team, while Negasonic remains her sardonic self throughout the film. But it's actually an interesting number of changes from the original characters in the comics.

NEGASONIC TEENAGE WARHEAD

Negasonic Teenage Warhead was first introduced (and promptly killed off) by Grant Morrison and Frank Quietly in the first arc of New X-Men. She was one of Emma Frost's students on Genosha and one of the millions of casualties when Cassandra Nova sent a wave of Sentinels to the city. She briefly returned as one of the projections Cassandra Nova used within Emma Frost's head during Astonishing X-Men but was seemingly destroyed in the process. However, Negasonic ended up being one of the many mutants restored by Selene during the events of the "Necrosha" storyline. She briefly hid away from the world as a regular human before being dragged back into the superhero corner of the world. She ended up joining the Mercs for Money alongside Domino. Negasonic has since become one of the last major allies of Deadpool since his mindwipe, helping him run his new mercenary business.

There hasn't bee a radical amount of change from the film and comics version of Negasonic Teenage Warhead. She was initially more of a look than a character, almost a parody of the goth look and not much else. The films modified the costume but also doubled down on the goth aspect of her personality. This new sarcastic take on the character ended up heavily influencing the comics version of the character, who now reads more similar to the movie version than her original incarnation.

YUKIO (AND SURGE)

Noriko Ashida as Surge from the New X-Men

The Yukio that appears in Deadpool 2 is actually an amalgamation of two Marvel characters: Yukio and Surge. Yukio is a Japanese ally of the X-Men who has been connected romantically to Wolverine in the past and developed an intense friendship with Storm. Despite being a human, she became a dedicated ally to the X-Men. She even informally helped raise Amiko, Wolverine's adopted daughter. However, the version who appears in Deadpool 2 isn't very similar to the shady but loyal ninja - beside her name. A more accurate version of Yukio appeared in 2013's The Wolverine, played by Rila Fukushima.

Her electrical power set doesn't belong to the comics Yukio, either. Instead, the young female mutant with electrical powers is Nori Ashida, aka Surge. She was one of the more prominent of the young X-Men during the Academy X era. However, she didn't have the full levels of control that Yukio possesses in Deadpool 2. She also wasn't nearly as cheerful as the Deadpool 2 version of the character. The comics incarnation of Surge was a more internally troubled figure, as befitting a young mutant who was almost murdered even more than most X-Men. In fact, the movie Yukio was somewhat unique in her cheerful attitude. It remains to be seen if Surge will pick up any changes to her personality to reflect the new version seen in the live-action film.
