Supergirl in the Multiverse: Earth-21

The universe presented by Darwyn Cooke in The New Frontier has the designation of Earth-21. This somewhat idealistic take on the early silver age of DC comics and how they brought forth a new age of superheroes after masked heroes became outlawed at the end of World War II. The initial New Frontier miniseries shows new heroes like Green Lantern and Martian Manhunter grow to prominence and work together with heroes like Superman, Batman, and Wonder Woman along with others to face a worldwide threat. This triumph would lead to a surge of new heroes including Supergirl.

Supergirl of earth-21 on shows up in 2 panels of issue 6 of New Frontier and even when she is shown it’s merely as a background character in a wide shot with other new and young heroes. Because of how the rest of the story is presented, it is likely this Supergirl (Kara Zor-L) shares many similarities to her counterpart of the pre-crisis earth-1. It is possible, that since the Superman as presented in New Frontier is further along in his superhero career, maybe Clark would have taken Kara in with him as opposed to leaving her in an orphanage. I’ve also seen reference to her being a part of the earth-21 Teen Titans, this is not directly stated at any point during any appearance of the universe. This universe is much more interwoven than the original silver age of DC comics so it would make sense for her to be a part of that team as opposed to a solo secret weapon for Superman.

As with all my Supergirl in the Multiverse posts, this is my own artwork. A digital drawing based on the cover to Action Comics #252, now showing the earth-21 Supergirl emerging from her rocket after it lands on earth. The top right corner has a motif of earth-21’s Supergirl’s symbol with a number “21” inside it.
