Captain Marvel who is an adult superhero version of Billy Batson who says, "SHAZAM!" Billy/Capt. Marvel has some Christian roots though some of them are not Christian (Only Christian related is Solomon in the first letter of the name, SHAZAM! Billy/Capt. Marvel is more of a Good Samaritan type of superhero). That is whom I feel connected to. I loved watching the Saturday morning version and the 1970's comic book version. Not the current ones since 1990's. Yuck!
In Christian view if Billy was real, he would called on the name of the LORD JESUS CHRIST! Then he is blessed with the power of God. The symbolic point of views are noted in the Captain Marvel and SHAZAM! comic books.
However, I rather to be ME as the superhero of God. Credited to save more than 50 Deaf people to Jesus Christ since my surrendering and accepting Christ as my LORD and Savior in March 1988.
God prefer you be superheros by witnessing, teaching, and preaching people to Christ. Missionaries, pastors, and other staff in your church including yourself as superheros.
