Tira was actually the character that stuck with me the most before I got into SCTira has the best abs imo. She always rocks the classic 2000's look with the Britney Spears-like washerboard abs and low cut pants or skirt. Hahaha!
She will experience fierce competition in that department from Barb, the lesbian barbarian who is confirmed DLC character 4 for season 2!!!
(Edit: oh... to answer the question this thread actually posed, I liked Nightmare. He was my first monster crush, lmao. #dead)
