Oggar was a selfish, vain young sorcerer in Bronze Age Greece whom Shazam took on as an apprentice. The old wizard hoped to teach him compassion and to use his powers for the common weal, but Oggar ignored even the lessons that Solomon sought to teach him. Eventually, he turned against the old wizard and his teachings, having found a new master in a sorceress called Circe.

The pair nearly beat Shazam in a magickal dual, but before they can kill him, Circe turns against Oggar, hitting him with a single curse as the old wizard got him with a four-fold one, even as Oggar gave the sorceress the immortality she craved. Shazam curses Oggar with the horns, legs and hooves of a goat and made him unable to use a spell more than once (without an outside power source) and Circe curses him with the inability to work his magic directly against any female of any age.

In the 2,500 years since that day, he’s found ways of overcoming both of those handicaps by using “catalysts,” people or objects that are literal storehouses of magickal energy, but the cost to the human versions is usually high. Figuratively speaking, they become soulless, burned-out husks, shadows of their former selves.

Chain Lightning is a young woman known as April Prentiss, but no one knows if that is even her real name. She is a dangerous sociopath whose studies in sorcery have given her the ability to absorb and discharge bolts of magick lightning from both her eyes and fingertips. This talent, coupled with her deep hatred of the Marvel Family in general and Mary in particular, makes her a deadly threat. She’s not above torturing her victims for the sheer fun of it, and takes almost childlike pleasure in the destruction she causes. She’s no longer truly human and doesn’t need to eat or sleep, but she has yet to suffer for it. She knows what the Marvel Family’s real forms look like, but doesn’t know their real names.

Dreamdancer uses a form of dance-magic to hypnotize her male victims into trusting only her. The “spell”, for lack of a better word, can only be reversed by someone forcing her to perform the movements in reverse. Nothing is known about her past, not even real name. Like Oggar’s magick, Dreamdancer’s hypnotic performances cannot affect other females.

Raised from birth on a secret “super food” created by his long-dead father Sigmund, Albrecht Krieger, also known as Captain Nazi, put himself into suspended animation in 1953, hoping to breathe new life into Hitler’s twisted dream in the future. After his awakening nearly fifty years later, Nazi spends a year learning of the changes the world underwent while he slept. Nazi is a villain with a brilliant scientific mind, enhanced strength, and faster-than-normal reflexes, but he’s not invulnerable, as evidenced by the scar on his face he received in a duel, and he also relies on a narcotic-like gas to fly. His gun, a specially modified Luger, can shoot a ruby laser “force beam” and bolts of electricity that can actually stun Captain Marvel and kill an ordinary person.

Although he can see a certain resemblance between Freddy Freeman and Captain Marvel Junior, it’s only that “they” are both dark-haired boys with dark blue eyes. He believes the “two boys” are merely friends and doesn’t realize that “they” are the same person.

Psiren is, more or less, an updated, upgraded version of Minute Man’s old foe, Illyria. Catarina Strausser, an empath with the power to manipulate and twist the emotions of others, is Captain Nazi’s lover. She feels she can do a better job of leading Nazi’s “cause” than he can, and often schemes of taking over.

King Kull is the “boogey man” of our collective unconsciousness who wants nothing less than the utter destruction of the human race that wiped out his technologically advanced people, the Beastmen, eons ago. What better motivation for a villain? He is a villain that is almost Captain Marvel’s physical match.

“Aunt” Minerva is the undisputed queen of the city’s underworld. Absolutely no criminal activity goes on without her knowing about or instigating it. She’s a crack shot who can shoot a blowfly off the end of someone’s nose without even grazing them. Minerva’s mind is filled with several decades of criminal genius driven by the hormones of an 18-year-old boy band fan. She’s managed to outlive five crime-lord husbands, all of whom have left her obscenely wealthy, and is currently hunting for number six, or at least a new boy-toy, whichever comes along first. She looks for any excuse to pinch Captain Marvel or to check out his... ahem ... assets, but she rules her gang with hot lead and an iron hand, doled out by both herself and her chief enforcer, a mysterious woman called Black Beauty. Neither she nor Black Beauty have any knowledge of the Marvel Family’s true identities.

Once a high-ranking Egyptian priest named Seth-Kerak, the Scorpion is a powerful psychic entity that has been permanently bonded with thug James Carlisle by a mysterious ritual, and many of the men who bound the Scorpion entity to Carlisle’s mind paid the ultimate price for their success. As Set-Kerak, he allied himself with Black Adam after the old wizard’s first heir killed the Pharaoh, stole his throne and put many of the Pharaoh's family and ministers to the sword.
During this time, Seth-Kerak commissioned the construction of Selket's Vengeance (a.k.a., the Scorpion statue) to aid Black Adam in his conquest of the rest of the known world. After Shazam banished Black Adam to the farthest reaches of space, he sealed Seth-Kerak's three souls (or ka, ba and akh) inside a stone called the Eye of Horus. When the Batsons found the stone, they inadvertently released Seth-Kerak's three souls from their prison.

Ebenezer “Ben” Batson, Billy’s estranged uncle and former guardian, is a thief, extortionist and loan shark. He casts Billy out of his home to die on the streets so he can steal the family’s wealth, but underestimates the boy’s courage and resourcefulness. Ebenezer is a crooked, tight-fisted skinflint who is known to have three judges in his pocket, and is not averse to using extortion, bribery, or even contracting a hit man to get what he wants.

Mr. Atom is an intelligent, semi-sentient robot created by Dr. Charles Langley to prove to his fellow scientists that nuclear waste could be used in positive, non-lethal ways. However, something goes horribly wrong with his programming. Deeming mankind a disease to be wiped out, he incinerates Langley into a pile of ash during a press conference which Billy Batson was attending.

Evil, in its three forms of Sin, Terror and Wickedness, has plagued mankind since the beginning of time. Trapped in a pit under the Rock of Eternity by old Shazam centuries ago, he sits and broods, plotting his escape from his prison and his revenge on his ancient jailer. Meanwhile his servants, The Seven Deadly Enemies of Man (Pride, Envy, Greed, Hatred, Selfishness, Laziness and Injustice), were turned into stone statues by Shazam’s magic. They now stand at the entrance of his chamber in the abandoned subway tunnel, a constant, silent reminder of eternal vigilance.
