Ever since debuting in the Season 2 premiere of Supergirl, the Daxamite superhero Mon-El has quickly grown to be a fan-favorite character in the Arrowverse series and Kara Danvers' biggest love interest on the DC TV show to date. Heroically sacrificing himself to save Earth in the Season 2 finale, Mon-El would reappear in the third season from the far-future sporting a new look as a member of the Legion of Super-Heroes.
Now, we're taking a quick look back at Mon-El's visual evolution in the Arrowverse and how his superhero uniforms compare to the original comic book source material ahead of his potential return during the upcoming "Crisis on Infinite Earths."
Mon-El Comic Book Costume
Created by Robert Bernstein and George Papp in 1961's Superboy #89, Mon-El was introduced as an amnesiac boy slightly older than Clark Kent who exhibited the same superpowers after crash-landing on Earth. Initially assumed to be Kal-El's older brother from Kryptonian due to his physical and powered similarities, exposure to lead poisoned Mon-El while restoring his memories as a refugee from the planet Daxam. To prevent the lead poisoning from progressing, Mon-El was placed in the Phantom Zone, where he was eventually rescued and cured by the Legion of Super-Heroes and joined the team in the far-future.
While Mon-El's superhero costume has seen revisions and changes over the years, his most enduring and classic outfit featured a bright red color scheme on the torso and pants, with long sleeves and a visible collar that went halfway up his neck. Attached by two prominent gold, round fasteners was a flowing bright blue cape, essentially making his classic costume a subtle inversion of Superman's usual color scheme to further allude at their initially assumed shared origin and familial link.
Mon-El's Original Arrowverse Costume
Season 1 of Supergirl had concluded with a cliffhanger ending as another rocket ship crash-landed on Earth, with its occupant initially unseen. The Season 2 premiere picked up immediately revealing the passenger to Mon-El, a young man from the planet Daxam. As Daxam had a long-standing feud with Krypton before the latter's destruction, Mon-El and Kara were originally at odds until romantic tension between the two characters gave way to a serious relationship. Gradually, Mon-El followed Kara's example to abandon his selfish ways and become a superhero, ultimately defending Earth from a Daxamite invasion.
The original Arrowverse costume worn by Mon-El is quite faithful to the original comic book source material though the colors are muted somewhat in comparison, similar to how Supergirl's outfit tones down Superman's color scheme. This costume is textured throughout with a prominent raised chest piece in the same shape as the Superman logo, although it lacks an emblem of its own. Blue accents are seen throughout the torso and pant legs while the gold fasteners are rectangular instead of circular.
Mon-El's Legion of Super-Heroes Costume
After sacrificing himself during the Season 2 finale, Mon-El was revealed to have been transported centuries into the future where he was rescued by the Legion of Super-Heroes. Joining the team, Mon-El married fellow Legionnaire Imra Ardeen to ensure interplanetary peace and becomes firm friends with teammate Brainiac 5. Reappearing in National City seven months after his disappearance, Mon-El reveals that he has spent seven years in the 31st century in the interim time period, ultimately returning to the future by the end of Season 3 to reunite with the rest of the Legion.
Mon-El's Legionnaire uniform is similar to Brainiac's, with a predominantly black and dark blue color scheme. The cape has been eschewed entirely and instead the costume is a clear two-piece with a tunic-like top with armor visible on the shoulders and forearms. However, given the likely reality-altering effects of "Crisis on Infinite Earths," there's no guarantee that Mon-El or the rest of the Legion will stick around much longer.
Returning Sunday, Oct. 6 at 9 p.m. ET/PT on The CW, Supergirl stars Melissa Benoist as Kara Danvers, David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen and Chyler Leigh as Alex Danvers.
