Scientist by Day. Monster by Night!
Geneticist Sarra Matsoukas, bitten by a vampire while studying the condition, injected herself with an experimental formula to stave off her full transformation. While Sarra continues to search for a cure by day, at night she becomes a bat-like monstrosity, Daywalker (PL 10), feeding on the blood of animals to slake her thurst.
Super Powered Legends. Because sometimes what you need is a character everyone will recognize, even if they’ve never met her before.
