Using only a human potential character, no superpowers or anything, Create the most formidable thing possible. You can use peak abilities, mental strength and willpower, natural magic accessed by those without a gene or innate power to source from and any skills. I'm looking for ideas for a character I'm writing about. He's a Vampire/Werewolf/Witch/Monster/Demon Hunter.
Think Batman but without a costume and with your own added flair. Thow in some artifacts useable by humans too, if you like
