Earth-7 is the designation in the DC Multiverse for Marvel’s 1610 universe, also known as the original Ultimate Universe that was published from 2000-2015 featuring titles such as Ultimate Spider-Man, Ultimate X-men, the Ultimates, and many other titles that often had the word Ultimate in their name.
The Earth-7 Supergirl is Carol Danvers. Carol Danvers in the main (616) universe of Marvel is the character Captain Marvel and is often viewed as the marvel equivalent to Supergirl. Carol Danvers of the Ultimate universe never became superpowered but was still active in the superhero community in many titles from this universe. She was also acting director of S.H.I.E.L.D. for a time.
Carol Danvers first showed up in the Ultimate Secret miniseries, before showing up in many titles in a supporting role and contributing to many event storylines and helped found the New Ultimates team after Ultimatum.
As with all my Supergirl in the Multiverse posts, this is my own artwork and it depicts Carol Danvers, Director of S.H.I.E.L.D. standing at a control station with her hand on a pedestal. Both the platform she is standing on and the pedestal she is placing her hand on are lit in a soft blue light. There are also 2 holographic displays around her. In the background is a window that shows New York City, the Statue of Liberty, and 2 Helicarriers. A motif in the top right shows the S.H.I.E.L.D. symbol and a 7 on top of it.
Earth-6 or better know as Just Imagine. Earth-6 was a short series of prestige format one shot comics with the premise of Stan Lee, prolific Marvel writer and creator of many characters from that universe, reimagining a handful of DC comics heroes. The series was published from 2001 to 2002 and was comprised of 13 stories. There was a one shot special in 2022 called Tales From Earth-6 that was put out to celebrate Stan Lee’s 100th birthday that further explored the universe.
The Earth-6 Supergirl is not a character that was introduced as part of the series. Because of this, I have taken some aspects of the stories and characters as presented in the Just Imagine stories and created my own backstory and character design.
Earth-6’s Superman is Salden who (during the events of Just Imagine Superman) stole a test prototype spaceship that uses a new element that can bend spacetime. Salden later (During Just Imagine Crisis) also landed back on Krypton and stole another sample of this element now know as Kryptonite. Salden, after landing on Earth became known as the hero Superman. My idea for a backstory involves Karron, the Super Girl from Krypton, being tasked by the Kryptonian government to follow Salden to Earth with a new spaceship and with a more advanced flight suit than Salden had, and bring Salden back to Krypton to pay for his crimes where he would be sentenced to the Phantom Zone.
As with all of my Supergirl in the Multiverse posts, this is my own artwork and it depicts Super Girl of Earth-6 in a costume designed with elements of Salden’s and other Kryptonian costumes and also depicts the Supermanor that Salden lives in on Earth as shown in Tales from Earth-6. In the top right there is a motif of the Supergirl S and a 6 on top of it.
Streaky the Supercat is a longtime friend, companion, and fellow superhero of Supergirl. He dates all the way back to Supergirl’s first year of publishing in Action Comics #261. Streaky, unlike Krypto, is a normal earthborn cat that only gained his powers from a stray piece of X-Kryptonite. X-Kryptonite was a substance Linda (Supergirl) Lee created when she was trying to create a way for her and her cousin to become immune to Kryptonite. X-Kryptonite was seen as a failure to Linda so she tossed it out her window which then got tangled up in a ball of yarn. Streaky, named by Linda for the iconic white streak in his fur, was a stray cat that turned up at Midvale Orphanage and immediately took a liking to Linda. One day Streaky found a ball of yarn and began playing with it not knowing it was the same ball of yarn that contained the X-Kryptonite which then gave Streaky super powers.
Streaky had many super powered adventures with Supergirl during this time and up until the Crisis when the universe got reset. This version of Streaky only had powers for a limited time and would have to be exposed to the X-Kryptonite, never-the-less he was still able to save the day along with Supergirl and the Legion of Super-Pets. Streaky was also always able to tell who his owner was whether she was dressed as Linda or as Supergirl.
Streaky is one of the most consistent supporting characters to Supergirl appearing in many iterations alongside Supergirl. In the post crisis universe there were a couple non powered versions of Streaky. During the Volume 4 Supergirl title a cat named Streaky appears twice and is a cat Supergirl saves from trying to fly. Later on once the post crisis Kara Zor-El shows up, she gets an orange and white tabby cat named Streaky that lives with her in her apartment. More recently, Streaky has shown back up again with his super powers back intact. Most recently he has been shown living with Power Girl and Omen in Power Girl’s current ongoing title, he does not seem to have to re-up his powers with X-Kryptonite every time he wants to use them anymore and instead just always has powers. While mainly living with Power Girl, he still goes out and has adventures on his own or with the Super-Pets.
Outside of main continuity, Streaky has also shown up in elseworlds titles like Tiny Titans and Cosmic Adventures in the 8th Grade. He also shows up quite often in TV shows such as Krypto the Superdog, Superman: The Animated Series, Justice League Action, and even showed up in an episode of the CW Supergirl show in his only appearance as a cat that isn’t orange (a black cat in this version).
I have often seen Streaky referred to as a girl cat, I assume because of his association with Supergirl. In my research I have only found two instances where Streaky has been depicted as a girl cat though. The first appearance of Streaky in the post-Flashpoint universe was in the first annual of Super Sons from 2017. Streaky is referred to with feminine pronouns and has a bit of a love triangle between Krypto, her, and Ace the Bat-Hound. The second was a bit more recently in the 2024 Super-Pets Special: Bitedentity Crisis. Once again Streaky is referred to with feminine pronouns and is saved by Bitewing along with the other Super-pets. Because of the timing of these two books along with the current ongoing Power Girl series we can either assume that there are 2 Streakys currently running around the DC universe with super powers, or more likely, the writers may not have checked if Streaky was a boy cat or a girl cat when they wrote these silly Super-Pets stories. A third possibility, which is my favorite, is that the Super-Pets of modern comics (including Detective Chimp) don’t realize that Streaky is a boy and assume that since she is the pet of Supergirl, Streaky is also a girl.
I am aware there are other appearances of Streaky that I didn’t mention and perhaps my research overlooked other instances where he was depicted as a girl, but I hope you enjoy this brief look at my favorite member of the Super-Pets.
Earth-5 is the home to Captain Marvel and the rest of the SHAZAM family, a group of heroes that have been bestowed upon them magical powers of SHAZAM. The wisdom of Solomon, the strength of Hercules, the stamina of Atlas, the power of Zeus, the courage of Achilles, and the speed of Mercury.
The Earth-5 Supergirl is Mary Marvel. Her civilian identity is Mary Broomfield, although she has sometimes gone by the name Mary Batson. She is the biological sister of Billy Batson, also known as Captain Marvel or SHAZAM. She first appeared in the Fawcett Comics published Captain Marvel Adventures #18 from 1942. In 1972 DC licensed, then later purchased outright, the Fawcett characters to publish in a new comic for DC SHAZAM #1 (1973). Mary Marvel and the rest of the Marvel Family have since been a part of the greater DC Multiverse as Earth-S and after Crisis on Infinite Earths would merge with a handful of other universes to become New Earth.
More recently during the Lazarus Planet event, from DC Comics in 2023, Mary loses her original SHAZAM powers and is granted new powers from Hippolyta where her new powers are all from goddesses. The agility of Selene, the strength of Hippolyta, the stamina of Artemis, the flight of Zephyrus, the invulnerability of Aurora, and the wisdom of Minerva.
As with all the Supergirl in the Multiverse posts, this is my own artwork and it depicts Mary Marvel flying through the sky. In the background on the left you can see the Rock of Eternity emitting a bolt of lightning that is striking Mary. A motif of Mary Marvel’s symbol is shown in the top right with a number 5 over it.
Earth-4 is the home of the superheroes who initially appeared in Charlton Comics such as Captain Atom, Blue Beetle, Peacemaker, and Nightshade. After Crisis on Infinite Earths this universe, as well as Earths 2, S, and X, combined with Earth 1 to create a New Earth.
The Earth-4 Supergirl is Bombshell. Captain Atom is most often seen as Earth-4’s Superman, and seeing that Amy Adams from New Earth underwent the same procedure that gave Captain Atom his powers it only makes sense for her to be Earth-4’s Supergirl. Bombshell (Amy Adams) is a member of the Teen Titans first appearing in Teen Titans #39 (2006) and had many appearances in that title until that book ended in 2011. She had a few other minor appearances but was usually only shown in team shots with the rest of the Teen Titans.
Amy Adams’ parents were part of Project Quantum and subjected her to the same Dilustel treatment that was given to both Captain Atom and Major Force. Her initial appearances showed her in an antagonistic role against the Titans. She was planted in the team as a traitor who would be revealed as such by Ravager. Later on in the Teen Titans run she would rejoin the team for real in an effort to redeem herself and attempt to become a hero.
As with all my Supergirl in the Multiverse posts, this is my own artwork and it depicts Bombshell on the left leaning against a wall with her arms crossed. In the background on the right is a computer screen reading “Project Quantum” and depicting my take on what Bombshell might have looked like if she had appeared in Charlton Comics alongside Captain Atom. A motif in the top right shows the Bombshell symbol and a 4 on top of it.
