Who is Doomsday, and why should we care about his fight against Superman, Batman, and Wonder Woman?

This creature is named Franche XO1111 , and has been referred to most often onscreen, and in the credits of each film, simply as the Alien. It was called an alien, and an organism, in the first film.
