Kal-El is the cousin of Kara Zor-El and the famous hero known as Superman.
Arrival to EarthEdit
Kal-El was rocked to Earth alongside his cousin Kara, from the doomed planet of Krypton. Making it to Earth safely, twenty four years later Kara's pod crash landed on Earth, and he left her with the Danvers family, scientists who had helped him understand his own powers.
Sending James to National CityEdit
He later asked James Olsen who he knew wanted to broaden his own horizons, to go to National City to keep an eye on Kara, and to deliver the blanket he was wrapped in as a baby, so she could use it as a cape. 
Kal-El was described by James to Kara as "everything you want him to be, and more".
