Blackjack is a white unicorn mare with a black and red mane, and is the lead protagonist in Fallout: Equestria - Project Horizons. She was once a resident of Stable 99 where she worked as a security mare. She can be obtuse, vulgar, and obscene in one moment and then in the next she’s kind, laughing, and more noble than any pony I know. She killed children one day and saves them the next. Is it some kind of schizophrenia, or can a pony actually survive being torn in two directions so severely?
