She-Ra
Ok, getting the whole mysterious vibe that you're throwing down. Promise not to blurt it out, but it's probably handy to let a few people know you can do that. You know, in case of emergency, break out the ghosts.
Nope, you're She-ra. That's your codename now. I give everyone a code name. And Goth-ra wouldn't make sense since that sounds closer to Mumm-ra who was a crusty old mummy that got buff because why not and fought a bunch of cat people.
I'd call you Xena but SHIELD already labeled Sif with that one. And Sif doesn't have a flying horse.
