Marvel has got a new TV show coming out, and it could feature the franchise’s first lesbian character on screen.

Runaways, based on the Brian K Vaughan and Adrian Alphona series, have revealed the new cast.

The characters are Alex (played by Rhenzy Feliz), a nerd who loves video games, Nico (Lyrica Okano), a ‘budding Wiccan’, Karolina (Virginia Gardner), a teen trapped by the expectations of her famous parents.

Also in the cast is Gertrude (Ariela Barer), a purple-haired, bespectacled girl with a strong sense of social justice, Chase (Gregg Sulkin), a high school jock who loves engineering, and finally, Molly (Allegra Acosta), the youngest of the friends.

In the series, the Runaways were a group of teens who were lifelong best friends forced to go on the run when they discovered that all of their parents are members of a supervillain team called the Pride.

As well as fighting bad guys and interacting with the wider Marvel universe, the series was known for its diverse line-up and pop culture references.

Spoilers ahead

In the comics, the team were shortly introduced to Xavin – a Skrull with shapeshifting abilities.

Karolina finds out she is actually an alien – a Majesdanian. For all of her life, her parents told her to wear a medical bracelet or she would die from a deathly allergy. It turns out it was just suppressing her true form – a rainbow-colored cosmic body with the ability to fly and shape light.

She is told the Skrulls and the Majesdanians are at war, and a marriage between the two might end the fighting.

But after a proposal from Xavin, Karolina refuses. And then she comes out.

But thankfully, Skrulls are not exactly limited by gender.

They quickly form a relationship, and Xavin ends up realising a female form is her at her most ‘natural’.

While it’s unknown whether Marvel will use this particular plot line, over the past 10 years Karolina Dean has always been confident in her sexuality.

Marvel’s Runaways will air on Hulu.
