A friend of mine lent me Dark Knights of Steel, Volume 1 awhile ago, and I finally sat down to read it today. Dark Knights of Steel sets Batman, Superman, and Wonder Woman in a medieval fantasy setting with an alternate history for Kal-El. In this setting, Kal-El's parents escaped the dying planet Krypton when his mother was pregnant; Kal-El is born on Earth. Batman's parents were the rulers of one of the three kingdoms, but after they were killed by the Green Man (Lex Luthor who found the Green Lantern ring and became the Joker), Kal-El's parents took over. Bruce was the bastard son of the Waynes (Thomas isn't his dad here) and so would never have been accepted as the ruler.
While the Els rule fairly peacefully, magic is banned from their kingdom. Batman is tasked with rounding all of the magic users up and imprisoning them. Due to this, and a prophecy from John Constantine, the neighbouring Kingdom of Storms wants the Els dead. With the help of the Green Man, Green Arrow launches an arrow and kills Jor-El, starting the three kingdoms' descent towards war.
What's really fun is that Dark Knights of Steel takes you in some really unexpected directions. There were a few moments that I did not see coming because the story plays with what you know of the characters: for example, Dark Knights of Steel's Kal-El is not the same (Superman) Kal-El who we're used to. But you don't realize it until the story unfolds.
I thought this was a fantastic reimagining of the three superheroes, and I can't wait for Volume 2!!!!
