The Man of steel prequel tells the "origin" story of Supergirl. It begins with her graduating and receiving a medal after lossing her friend to a murderer who she captured during her final test. This was the first murder on Krypton for over a thousand years. Kara is sent along with a few others into space to cary the El name across the galaxy. They go to sleep in a "Kryo chamber" but, when Kara wakes up all hell breaks loose. The comics story is great. Its a 40 page comic that is written by Goyer and Snyder. Its well worth the read. It also leads to believe Supergirl will make an appearance is Man of Steel
