DC and Marvel have a superhero named Captain Marvel, but DC's Captain Marvel is more popular (The character with the white cape and is red with a lightning bolt on his chest)

No. DC's first comic book title was Detective Comics #1 (which is what "DC" originally stood for) in 1937. Marvel Comics #1 (featuring the Sub-Mariner and the Human Torch) was published in 1939, by Timely Comics, a few months after DC published Action Comics #1 (with the first Superman story). The company changed its name from Timely Comics to Atlas Comics in the 1950s, and to Marvel Comics in 1962.

Captain Marvel is better then Super man because superman is weak to magic and captain marvel's powers are magic. So captain marvel can school Superman any day!

Some popular girl superheroes include Wonder Woman, Supergirl, Captain Marvel, Black Widow, Storm, and Batgirl. These characters are known for their bravery, strength, and heroism in comic books and movies.
