I will give you a list of major ones who I think are good frankly I never worry about the whole spin off aspect as long as they bring something NEW to the table besides gender but I will talk about that.

Power Girl is TECHNICALLY a spin off of Superman but she has her own name and style and often is not really part of his stories the Palmioti/Conner run is a good one for her.

Black Canary has VARIOUS solo runs and Mini series, I like her in the Green Arrow 90's stories where she becomes the co-star in all but name, and Birds of Prey was ACTUALLY mostly about her so I recommend that run specifically the Gail Simone era.

She Hulk might SEEM like a female Hulk, but starting with her late 80's run turned into a MUCH more unique character to the point that I often call her the Wonder Woman of Marvel, she has a comedy focus and DID the deadpool 4th wall thing WAY BEFORE him.

Stargirl is not really a spin off of a male counterpart, it's complex but the character she is based on IS VERY obscure and she has eclipsed him in name and role.

Some people might argue this but it should be noted that Witchblade lasted DECADES and still has a place in comics. Her new series I find eh, but her classic comics are solid cheese and the Ron Marz run is considered some of the best stuff of it's time.

This is a spin off but I feel I need to talk about this, Spider-girl is the ONLY MARVEL heroine to make to 100 straight issues without a relaunch NO ONE ELSE has made it without a renumber or a break in publication. She sold so well she made it to 100.

Black Widow even before the Avengers push was in a bunch of solo material of varying quality, a cool character sometimes given the shaft in terms of comics but she has various mini series.

Black Orchid is kind of an obscure one, but this was Neil Gaiman first crack at a dc character before Sandman and she got a Vertigo series by someone else later, you will either like this or find it pretentious but it's out there.

All right time to talk about the 90's Supergirl comic, So at the time Superman was MEANT to be the only actual Krptonian in comics this meant that Supergirl is not from Krypton, and the Peter David run is a story about an angel with the Superman symbol.

Why I bring this up, is that he later made a creator own Character called Fallen Angel that was meant to be HER, so if you want context for that run at least in a meta sense you can look to her as a spin off who very much is her own thing even though legally she can't

Catwoman is a borderline case but she's been able to maintain a solo for decades and I feel like she has a lot of good material. She doesn't become female Batman ever. I recommend the Ed Brubaker stuff.

Chase is not a long lasting one and is NOT a superhero story but.... created before Jessica Jones this agent who looks into the superhero world has a secret and this look into heroes was rather unique at the time plus it has STELLAR art. Easy read.

Madame Xanadu is a pretty good as well, she had a more recent vertigo run that was very acclaimed and plays with Arthurian lore and redemption. A cool character not a lot of people talk about.

Another one who is technically a female spin off is Kate Spencer the Manhunter, now SHE has the longest ongoing compared to her male counterparts and only one other Manhunter is considered essential. Essentially a single mom layer superhero this comic is a banger.

Promethea by Alan Moore. It's a weird one but it's out there.

and We will leave it off with Zatanna, a major DC heroine she is technically a female spin off too but NO one cares about Zatara. She has had various runs over the decades some good, some okay. There is only ONE really bad moment with her ever and it's not in one of her series.

Yeah there are more these are just the ones that come to mind and keep in mind various superteam books can have a lot of females heroes like Runaways and even some X-men teams. I don't worry about Spin off heroines because honestly there are MORE good then bad.

If anyone wants to put some recommendations here feel free. I know I'm forgetting some here and there.
