Ki is a strong-willed young Martian who learned to speak English by watching a '70s sitcom. She spends her time painting elaborate graffiti on the walls of Mars, but she does so in secret since the Martians are strictly forbidden from expressing any individuality. Along with her native Martian tongue, Ki can speak a wide vocabulary of Earth words and even numbers. Albeit, mostly through slang and impersonations, she picked up off a random 70s sitcom.
