S for the wisdom of Solomon As Captain Marvel, Billy has instant access to a vast amount of scholarly knowledge. The wisdom of Solomon also gives Marvel clairvoyance and provides him with counsel and advice in times of need. In early Captain Marvel stories, he also had knowledge of all languages and sciences, ancient and modern, and could hypnotize people as well, through this power.
H for the strength of Hercules* Dubbed “The World's Mightiest Mortal,” Captain Marvel has incredible amounts of super strength, and is able to easily bend steel, punch through walls, and lift massive objects. Marvel's strength is enough that he has fought beings such as Superman and Wonder Woman to a standstill.
A for the stamina of Atlas Using Atlas' endurance, Captain Marvel can withstand and survive most types of extreme physical assaults. Additionally, he does not need to eat, sleep, or breathe and can survive unaided in space when in Captain Marvel form.
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, grants magic resistance against all magic spells and attacks, as well as allowing for interdimensional travel. Marvel can use the lightning bolt as a weapon by dodging it and allowing it to strike an opponent or target. The magical lightning has many uses, including creating apparatus, restoring damage done to Marvel, or acting as fuel for magical spells.
A for the courage of Achilles Like the wisdom, this aspect is primarily psychological, and gives Marvel superhuman amounts of inner strength on which to draw. In the recent Trials of Shazam! series, this quality has been officially changed to the one Achilles is famous for: His near absolute invulnerability.
M for the speed of Mercury By channeling Mercury's speed, Captain Marvel can fly and move at supersonic speeds, and, in space, at faster than light speeds. With Judd Winick's Trials of Shazam! series, Marvel has also gained the ability to wield magic and cast spells. These additional abilities are also attributes from the god Mercury.
