Zoë's love of superheroes and all things Marvel & DC started out in childhood, and has blossomed into a career getting to talk about some of the biggest and best movies and shows of all time, having previously focused on comics while working at WhatCulture.

Supergirl's new villain power upgrade already changes what's possible for the DC movie's ending and how it will need to go about adapting the source material it draws from. The DCU timeline has already introduced a range of powerful and impressive villains over the course of its first year, with more evidently on the near horizon based on Supergirl's trailers and the promising teases of what's to come for releases like Lanterns.

With Supergirl set to adapt the story of the Supergirl: Woman of Tomorrow comic - based on it featuring key characters like Ruthye, Krem of the Yellow Hills, and Krypto in what is evidently an adaptation of some of the comic's biggest events - we already have a reasonable idea of what to expect from the movie's plot, and the stories and fates of its various characters.

However, it's also clear that the film intends to make some major changes from the comics to be its own separate entity. The presence of Jason Momoa's Lobo - who did not feature in the Woman of Tomorrow comic story - was evidence enough of this, but the latest Supergirl trailer has proven this further with one interesting villain power upgrade it reveals, which presents interesting changes for the story.

From the first moment we saw the Supergirl movie's version of Supergirl: Woman of Tomorrow comic villain Krem of the Yellow Hills, it was clear the film take on the character would be decidedly different.

Rather than the more fantasy rogue hunter style design we got in the comics, the movie has taken Krem in a more sci-fi direction, giving him metal armor, shaving his head rather than giving him a bushy ginger beard and hair, and also includes piercings all over the character's skull.

Interestingly, the new Supergirl trailer also shows that this version of Krem has superstrength, which the comic version of the character didn't appear to. After the shot showing the new Krem design once more, the trailer sees Krem hold up a tank with one arm before throwing it aside, suggesting he or otherwise the new suit he wears is capable of some colossal feats in this regard.

This is worth noting for a few reasons, but one of the most pressing is that, since Supergirl appears to be adapting the story of Supergirl: Woman of Tomorrow, this will change the film's adaptation of the comic's ending - since this features a fight between Krem and Ruthye, the girl Supergirl travels throughout the galaxy with in the movie, who notably doesn't appear to have powers in either the comic or movie itself.

Why The Supergirl Villain Change Makes Sense For The Movie

While Ruthye now appears to have a substantial disadvantage in the Supergirl movie in her quest to find and get revenge on Krem - unless she also gets a power upgrade in the upcoming film - the call to give Krem a power boost does make sense for the film itself.

Though there was a unique appeal in Krem seemingly being drastically outmatched power wise by Supergirl in the original comic - both further explaining why he fled her, and providing Supergirl with a moral matter since she could theoretically kill him outright with little issue. However, this angle isn't strictly removed by Krem gaining powers, and this allows for some more action to be infused into the story.

Similarly, the Krem vs Ruthye fight is all the more engaging if Ruthye is even more clearly the underdog of the two, and the superhero genre has certainly shown time and time again that it can pull off a hero beating a far more powerful foe in a way that still feels believable. As such, the changes made with Krem in Supergirl should still allow the movie to keep to the original spirit of the source material, even if some aspects of its story are different.
