Ghost Rider has superhuman strength and durability, as well as the ability to project and control Hellfire, which can sear the soul as well as burn the flesh. He can shape his Hellfire into a mystical motorcycle capable of traveling over water and up vertical surfaces. He is also immune to any mystical attacks that are specific to beings with living souls.
Blaze is a world-class cyclist capable of seemingly impossible stunts. He is also an excellent shot with pistols and shotguns and has limited knowledge of the occult.
When Blaze becomes the Ghost Rider he has complete control over a Hellfire Enchanted Chain which is nigh-indestuctible.
Blaze has used a variety of modified motorcycles in his career, and once used a shotgun through which he discharged Hellfire.

When Teth Adam/Theo Adam says the magic word "Shazam", he is transformed into Black Adam and granted the following powers derived from ancient Egyptian gods:
S for the stamina of Shu: Using Shu's endurance, Black Adam 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.
H for the swiftness of Heru: By channeling Heru's speed, Black Adam can move at sub-light speeds in orbit. In outer space, Black Adam can fly at trans-light speeds, while on Earth he has been depicted running at a maximum Mach 500. He was able to give his speed to the Flash (Jay Garrick), running at incredible speeds with him.
A for the strength of Amon: Black Adam has a phenomenal level of super strength, able to easily bend steel, punch through walls, and lift massive objects. Adam's strength is generally depicted of being on levels equal to those of Superman and Captain Marvel, though some writers have portrayed his strength as possibly outmatching them; on at least one occasion, he has been able to successfully hold his own against an assemblage of the Justice League, Justice Society, Great Ten, and the Teen Titans.
Z for the wisdom of Zehuti: Black Adam has instant access to a vast level of scholarly knowledge, which allows him to know multiple languages. The wisdom of Zehuti also provides him with counsel and advice in times of need.
A for the power of Aton: Aton's power allows Black Adam to fly, fuels the magic thunderbolt that transforms Adam, enhances Adam's other physical abilities, and provides magic resistance against a massive amount of magic spells and attacks. Adam can use the lightning bolt as a weapon by dodging it and allowing it to strike an opponent or target. It allows him to travel to the Rock of Eternity.
M for the courage of Mehen: This aspect is primarily psychological, and gives Black Adam superhuman amounts of inner strength from which to draw, and possibly great fighting skills. His strength of mind renders him resistant to telepathy and mind control. In some depictions, the courage of Mehen also provides a degree of his invulnerability to harm.
Additionally, Adam's senses are acutely sharpened. Black Adam has repeatedly been described as a warrior who had proven himself to be highly skilled even before he was given the power of Shazam.
