Captain Surprise was a cartoon character in a small company in his early years. This small company saw that Superman in DC was a big hit, so it imitated Superman's appearance and settings and set up a superhero called Captain Surprise. Moreover, the sales volume of Captain Surprise comics once surpassed Superman's comics, and its popularity almost surpassed Superman's. Then DC sued the small company.
While the two companies were busy with lawsuits, Marvel Comics launched his own Captain Surprise and registered the trademark of Captain Surprise. The result of the lawsuit was that DC won. The small company lost a lot of money to DC. Later, DC bought this small company, and Captain Surprise became a superhero of DC, but it was hidden in the snow by DC, and Captain Surprise was not shown for a long time. Then, because Marvel Comics registered the trademark of Captain Surprise, DC could no longer use the name of Captain Surprise, so it changed its name to Shazam.
