Elsa Bloodstone is a character appearing in American comic books published by Marvel Comics. Created by Dan Abnett and Andy Lanning, and Michael Lopez, the character first appeared in Bloodstone #1 (December 2001).[1][2] Elsa Bloodstone is the daughter of the previously established Marvel Universe character Ulysses Bloodstone and the sister of Cullen Bloodstone. She has been a member of Nextwave, Midnight Sons, and Fearless Defenders. As she is a young, female monster-hunter there are potential similarities with Buffy the Vampire Slayer, although when asked about this the authors claimed "neither of us have seen an episode of Buffy all the way through! I know we're missing out on some great TV but we've determined to steer clear of Buffy at least while we're doing Bloodstone."[3] Elsa Bloodstone appeared in the Marvel Cinematic Universe / Disney+ television special Werewolf by Night, portrayed by Laura Donnelly.
