It’s that time of the year again! 2026 marks the 86th Anniversary of Billy Batson as Captain Marvel debuting in Whiz Comics #2, the first official cover-dated issue released February 1940.*
Billy Batson is a young orphan boy who transforms into a powerful champion named Captain Marvel at the drop of the word “SHAZAM!” He fights crime against notable villains together with a memorable cast of heroes he calls family.
SHAZAM! Each letter from Billy Batson's magical word represents a power likened to a famous mythological deity or hero. Interpret both the figure or the gift however you see fit.
