S         for the wisdom of Solomon         As Captain Marvel, Billy has instant access to a vast amount of scholarly knowledge, including most known languages and sciences. He has exceptional photographic recall and mental acuity allowing him to read and decipher hieroglyphics, recall everything he has ever learned and solve long mathematical equations. He also has a great understanding of divine phenomena in the mortal world. The wisdom of Solomon also provides him with counsel and advice in times of need. In early Captain Marvel stories, Solomon's power also gave Marvel the ability to hypnotize people. (Solomon is the only figure in the list not taken from Greco-Roman mythology.)

H         for the strength of Hercules         Hercules' power grants Captain Marvel immense superhuman strength, making him one of DC Comics' strongest characters; he is able to easily bend steel, punch through walls, and lift massive objects, (including whole continents like South America). In the comics, this strength has evolved in parallel to that of Superman.

A         for the stamina of Atlas         Using Atlas' stamina, Captain Marvel can withstand and survive most types of extreme physical assaults, and heal from them. Additionally, he does not need to eat, sleep, or breathe and can survive unaided in space when in Captain Marvel form. Pre-Crisis, it was implied in some stories to give him invulnerability.

Z         for the power of Zeus         Zeus' power, besides fueling the magic thunderbolt that transforms Captain Marvel, also enhances Marvel's other physical and mental abilities, and grants him resistance against all magic spells and attacks. Marvel can use the lightning bolt as a weapon by dodging it and allowing it to strike an opponent or target. The magic lightning has several uses, such as creating apparatus, restoring damage done to Marvel, and acting as fuel for magic spells. If Billy is poisoned, for example, transforming will enable him to survive. Pre-Crisis, it was claimed in some stories to give him invulnerabilty. It can also turn other Marvels back by striking them. It aids interdimensional travel at the Rock of Eternity.

A         for the courage of Achilles         This aspect gives Captain Marvel the courage of Achilles, giving him bravery and in one story it is claimed to give him fighting skills. In the Trials of Shazam! mini-series, this was changed to Achilles' near invulnerability. It also aids Captain Marvel's mental fortitude against most mental attacks.

M         for the speed of Mercury         By channeling Mercury's speed, Captain Marvel can move at superhuman speeds and fly, although in older comics he could only leap great distances. This also gives Marvel the ability to fly to the Rock of Eternity by flying faster than the speed of light.
