Sure, if you love Superman you know that his Kryptonian name is Kal-El. Kal is his first name, and El refers to the house of El. In fact, the popular 'S' on his suit is the crest of the house of El in Krypton.
Nic Cage and Alice Kim
named their child, Kal-El after Superman. If you think about it, the name has become so ingrained in our pop culture lexicon that this doesn't seem weird. Some sources say the name sounds almost like the Hebrew words for "voice of God."
At least it's cool.
