Shazam is already busy making waves in the wake of that splendid Comic Con trailer, but it stands to reason that audiences won't be overly familiar with his move-set. The trailer established his bullet-proof body, his strength and his flight (sort of), but stopped short of depicting all the wonderful other abilities Billy Batson has in his arsenal.
The original Captain Marvel may look like just another version of Superman on the surface, but his abilities are magical in nature, and don't stem from a sci-fi premise. They actually originate with the Greek and Roman Pantheon of Gods, with the character possessing the wisdom of Solomon, the strength of Hercules, the stamina of Atlas, the power of Zeus, the courage of Achilles, and - most pertinent of all - the speed of Mercury.
Shazam is very fast, and can move past the speed of light. At one point he moved so fast that he entered the fifth dimension, placing him among the fastest beings in the DC Universe and ensuring that his counterpart in Metropolis keeps a watchful eye over his shoulder when it comes to competition.
