I am actually surprised this hasn't been done yet. Not that I've found anyways. But a fic where Lexa and Clark are reincarnations of Xena and Gabrielle. I'm an awful writer but this would be amazing. I mean a fierce brunette warrior whose horrific experiences make her strive to bring peace that mentors and falls in love with a spunky blonde who wants nothing but peace who slowly descends into darkness to become a capable warrior. It's almost too perfect. Someone please write this.
