WARNING: This article contains major spoilers for “Immortal Kombat,” the Supergirl Season 5 finale.
Alex Danvers rocked a new costume in the Supergirl Season 5 finale.
In “Immortal Kombat,” Alex followed her girlfriend Kelly’s advice and suited up to fight Leviathan. Now, she is a costumed vigilante, just like her sister Supergirl — and like Supergirl, Alex decided to forgo a mask. Instead, she wears a hood when she is out in the field. She also put on some intense black and blue makeup and added a blue streak to her hair to match the colors of her suit.
If the costume looks a little familiar, that’s because it takes a little inspiration from “Alex in Wonderland.” In that episode, Alex used Obsidian VR to become her own version of Supergirl. Inside the virtual world, she wore the Girl of Steel’s costume in a black-and-blue color scheme. Her vigilante costume, as pictured above, borrows heavily from that design.
Although Alex doesn’t have any superpowers, her costume does come with a defense mechanism. Earlier in the season, J’onn gave her a piece of Martian technology that can become any weapon the user wills. Alex wears this around her wrist like a bracelet. It also appears in the photo above, like a golden bangle with a glowing red light. She used this mechanism several times in the finale to conjure up guns and other weapons.
In “The Missing Link,” Kelly was the one who suggested Alex should mask up. After their missions went wrong, the couple expressed regret about rushing in. For Kelly, that meant she lost Andrea’s confidence; for Alex, however, that meant putting someone else’s life in danger. This led to Kelly’s epiphany. When Alex joked about wearing a mask, Kelly insisted, “It worked for my brother. If you’re going to be a vigilante, you might as well go all the way.”
This seems like a natural progression for the character. Up until “Crisis on Infinite Earths,” Alex had worked for the Department of Extranormal Operations (DEO). However, when Lex rewrote reality to become head of the DEO, Alex quit. Ever since, she has felt adrift. This — and her father’s death — eventually drove her into Obsidian’s virtual reality, where she masqueraded as Supergirl. Although it eventually went terribly wrong, the experience helped her develop a taste for helping others as a vigilante as opposed to a government agent. As such, it isn’t a surprise to see Alex adopting her own vigilante persona.
Returning to The CW in mid-2021, Supergirl stars Melissa Benoist as Kara Danvers, David Harewood as Martian Manhunter and Chyler Leigh as Alex Danvers.
In the Supergirl Season 5 finale, Alex Danvers took Kelly Olsen's advice and debuted her very own vigilante costume.
