One of the most common types of superhero names. Simply stick "Captain" in front of this hero's name, and then whatever (usually) noun the writer wants. Perhaps it's to give the impression of leadership, as though this character actually is The Captain. This character won't actually be a captain of some military group, but will often be The Good Captain. This can even happen with villains as well, although it's rare, and often reserved for parodies. Compare Something Person and Captain Space, Defender of Earth! (which this can overlap if a character is a space hero and a superhero).
