Solicitations for upcoming issues of the new Supergirl ongoing title mention a character called Satan Girl, but who is she? In this post I’m going to go over all the character’s appearances and discuss what might happen when she shows back up in Supergirl’s life. Looking at her lists of appearances can be somewhat deceiving because she shows up in Adventure Comics 313, 409, and 500. However, the appearances in issues 409 and 500 are just reprints of her story from Adventure Comics 313 from 1963. She wouldn’t show up again in a new story until the pages of Legionnaires 17 from 1994 during the events of Zero Hour.

Adventure Comics #313 is the first appearance of Satan Girl and it was released in 1963. The issue as originally printed contains 2 stories, The Condemned Legionnaires and Father’s Day on Planet Krypton. Since Satan Girl only shows up in the first story that’s all we’ll talk about today. The Condemned Legionnaires was written by Edmond Hamilton, with art by Curt Swan, Sheldon Moldoff, and George Klein, and lettering by Milt Snapinn. The story is a Legion of Super-Heroes story and as such takes place in the 30th century. The story begins with a brief montage of all the female Legionnaires contracting some strange Crimson Virus that seems uncurable. Because of this strange disease and the uncertainty of how deadly it is to other citizens of Earth, the unaffected male Legionnaires send all their female teammates to the Quarantine Planet. Before the remaining members of the team have time to act on finding a cure they are met with a strange visitor in black and purple who claims to be more powerful than all the girl members of the team combined.

This girl is Satan Girl! A powerful being who can fly under her own power without the use of a flight-ring or flying-belt and also has superb strength, speed, and invulnerability. Se also has heat vision and can survive the vacuum of space without a space suit. Not only is she immensely powerful, she reveals that she caused the outbreak of the mysterious Crimson Virus. Before the Legion can apprehend this devilish fiend, she destroys their rocket and flies away leaving the Legion of Super-Boys to turn to the only hero that would be powerful enough to stand up to this new mystery foe; Supergirl. Supergirl, having just arrived to her visit to the 30th century, urges the Legion to follow her to the Quarantine Planet so they can tackle the threat of the Crimson Virus and Satan Girl.

It is here that Supergirl and Satan Girl confront one another for the first time and Supergirl notices that her foe wears a lead-lined mask to conceal her identity from anyone with x-ray vision. While her power set matches her with beings of both Krypton and Daxam, having a lead-lined mask confirms to Supergirl that this foe must be from Krypton since lead is fatal to Daxamites. The 2 girls have a brief tussle and Supergirl tries using her heat vision to melt the lead mask of her foe to find out the identity of this mystery Kryptonian. Satan Girl seeing through this plan quickly maneuvers away from the girl of steel and escapes. However, Supergirl has a new plan involving a certain radioactive green rock. Supergirl, now Kryptonite in hand (in a protective lead box of course), tracks Satan Girl to an asteroid hideout when Supergirl ambushes her with the Kryptonite when she is dumbfounded to see had no affect on her adversary. Satan Girl is easily able to flee from Supergirl to continue carrying out her nefarious deeds.

Being unsure where Satan Girl has run off to, Supergirl decides to regroup with the Legion (boys AND girls this time) and takes the whole team to a mysterious planet only she knows about to regroup and come up with a new plan of attack. Supergirl, now thinking Satan Girl is an android due to her immunity to Kryptonite, concocts a gas gun that can immobilize androids when next they meet. Their next meeting comes much sooner that expected though as Satan Girl shows up on this secluded planet that only Supergirl knows about. Supergirl tries the anti-android gun and Satan Girl (literally) laughs it off exclaiming “You’d be amazed if you knew who I really am!” The natives of the planet, seeing Supergirl and the Legion in trouble, then gang up on Satan Girl distracting her long enough for the team to make an escape to a second secret planet know only to the maid of might.

Unfortunately for the saviors of the 30th century, they are once again quickly tracked down by their newfound foe who quickly downs Supergirl with armfuls of Kryptonite. In her weakened state, Supergirl tells Lightning Lad to gather the Legion of Super-Pets to help take down this impossible foe. With the combined strengths of 4 super-powered animals, they are finally able to subdue Satan Girl who is finally unmasked and revealed to be none other than… Supergirl!?

Satan Girl then reveals her origin and her plans. Apparently, when Supergirl landed in the 30th century this time she came out of the time barrier right next to some Red Kryptonite which created a copy of Supergirl. This copy, knowing she only had 48 hours of life before the Red K wore off, thought up a plan to live on forever involving expelling the Red K onto the female Legionnaires. Wearing a lead costume had the added benefit of protecting her from the dangerous rays of Green Kryptonite along with protecting her identity which helped her out of a couple jams in this story. However, all her plans were for naught as she ended up merging back with Supergirl at the end of the 48 hours.

And it’s here where the story ends, a surprisingly unceremonious end to this duplicate girl of steel who wanted nothing more than to live. She did of course try to kill many people to secure her life but it seems odd that the story seems to end without any sort of farewell to the character.

Satan Girl wouldn’t appear again in a new story until 1994 in Legionnaires #17. Written by Mark Waid, art by Chris Gardner, Dennis Cramer, and Tom McCraw, and letters by Pat Brosseau. This story History Lesson functions as the start of the conclusion arc of the Legion story End of an Era which was their tie in to the Zero Hour Event. This story dealt a lot with weird time travel shenanigans and multiple copies of Legionnaires and all around a confusing issue to read in isolation. However, since we’re not doing a full breakdown of the issue and just here for Satan Girl, we can skip right to page 14.

Satan Girl bursts onto the scene leading a Legion of Supervillains who then attack this combined Legion mostly as a distraction while Glorith and Mordru capture the elder Rokk Krinn who, in his unstable condition, was attacking the Legion at the start of the issue.


Unfortunately, due to the nature of the set up of this story, Satan Girl serves little purpose aside from being a callback to a past Legion story. In what basically amounts to a cameo appearance, Satan Girl has no lines and briefly fights a few members of the team before ultimately vanishing away. There is an almost reference to Satan Girl’s true identity when Inferno says “She’s the most powerful — a duplicate of –” before getting punched. Obviously a reference to Satan Girl who is of course a duplicate of Supergirl and fought a previous incarnation of Inferno when he was still going by Sun Boy.

And now we come to Satan Girl’s first new appearance in 30 years, Supergirl #3. This book comes out next week (July 9th, 2025) and features Satan girl prominently featured as a dark half of our heroic protagonist. While Satan Girl herself hasn’t shown up more than the 2 times before this, Supergirl fighting a dark version of herself has come up quite frequently. When facing off against Nightflame in Adventure Comics #421, the dark sorceress has Supergirl face off against a darker less heroic version of herself in Nightflame’s home land of Innerverse. The most direct retelling of the tragic tale of Satan Girl comes from the pages of Supergirl (Vol. 5) #5 which I covered as part of my Supergirl vs. Supergirl post. This story also involves Supergirl being split in two and the dark half wanting to live and the two halves merging back together at the end.
Satan Girl is truly a tragic tale more than anything else. This duplicate of Supergirl entered life knowing she only had 48 hours and she tried everything she could to continue living. Unfortunately this Maiden of Fright was unable to see her plan come to fruition and suffered for it. In Sophie Campbell’s book that’s set to come out I’d like to see more of this exploration and maybe finally get some follow up where Supergirl tries to save Satan Girl and not just let her disappear into nothingness for another 30 years. Red Kryptonite is the version with the most unpredictable outcomes, but I think with the presence of Lesla-Lar’s superior scientific mind she may find a way to tune Red K to always give her the outcome she desires.
Thanks for reading! I hope you all are looking forward to the ongoing adventures of Supergirl as much as I am, and I hope you enjoyed my look at the dark duplicate that is Satan Girl.
