Ellen Ripley should be in DBD
Don't even need to include the Xenomorph. But Ellen Ripley is definitely Survivor material. There's just enough to fit into the lore that she was taken by the entity whether it be the original before her demise or the clone when they crash land on Earth.
She is without a doubt the most badass female protagonist out there. I can't think of another character who's more well-known in a horror movie franchise than Ripley.
