Black Adam was immediately impressed with Adrianna's fiery spirit; so much so, he asked Captain Marvel to bequeath Adrianna with the powers of a goddess. Upon holding an ancient amulet and speaking "I am Isis ", Adrianna transformed into the famed Egyptian deity with a flash of lightning. After falling in love, Adam and Adrianna were married. Shortly after their wedding, Adrianna resumed her quest to rescue her captured brother.
Black Adam and Isis located Amon where Intergang was attempting to recruit new soldiers through brainwashing and torture. After refusing to comply, Amon was badly beaten and left for dead. As Amon struggled for his life, Black Adam shared a portion of his powers with his newfound brother-in-law. Upon speaking "Black Adam", a bolt of lightning immediately healed the young man, and transformed him into Osiris. Now blessed with the powers of the gods, Amon joined his sister and Black Adam in helping them change the world.
Amon loved being with his sister and brother-in-law and then he found his first friend when a dimensional thing went wrong, Sobek the talking crocodile. He also joined the Teen Titans. Then, on a way back from a mission they were attacked by the Suicide Squad and to save his sisters life he accidentally killed the Persuader and the footage of it was recorded by Amanda Waller. He was kicked out of the Teen Titans because of it and stricken by Grief he went to the Rock of Eternity to ask the Marvels to get rid of his powers claiming that Black Adams influence was making him evil. Then, Black Adam came in and fought Osiris but was stopped by Isis. Osiris relents and goes back home. When he goes outside, he plans to leave Kahndaq but then Sobek tells him he can get rid of the curse if he says his name and he does he do it. Then he is unexpectedly devoured by Sobek who was revealed to be one of the first horsemen, specifically Famine.
Osiris was brought back as a Black Lantern during Blackest Night. Due to his magical powers, he was able to shake off the influence of the ring, destroying Sobek and himself in a burst of lightning. He was later fully resurrected by the power of the White Lanterns. The reasons for his resurrection is yet to be revealed.
Osiris returns to Kandaq, and takes the statues of Black Adam and Isis.

Powers and Abilities
Power of the Egyptian Gods: Osiris was bestowed the powers of the Egyptian Gods by the master sorcerer Black Adam. Unlike the other members of the Marvel family instead of deriving his abilities from Shazam himself Osiriss powers are drawn directly from Black Adam himself. When Osiris speaks the name of “Black Adam” he is transformed into the avatar of the the Egyptian Gods known as "Osiris".
Osiris also has the ability to share his powers with others that he chooses (for example: Osiris) just like the other members of the Marvel family.
S for the Stamina of Sh u- Shu has granted Osiris protection against extreme physical assaults. Shu also grants Osiris the ability to survive without having to eat, breathe or sleep.
Self-sustenance- While in the form of Osiris, Osiris does not need to eat. sleep or breathe. The godly energies that transform his body into Earths Mightiest Hero is enough to sustain his body. From Osiris, who also shares the same powers as Osiris (but from different sources) we have seen that he was able to survive crossing the universe in his return to Earth which took him 5,000 years to accomplish.
Superhuman Stamina- Osiriss godly energies do not require him to rest and prevent any kind of fatigue toxins from building in his body granting virtually inexhaustible amounts of endurance no matter how strenuous the physical activity he is engaged in.
H for the Swiftness of Heru: Heru grants Osiris the ability to fly and move at incredible speeds. While in Earths atmoshere Osiris is able to achieve speeds of Mach 10. Osiris speeds does not rival that of the flash but it has been said that he is capable of running at speeds of Mach 500.(Though it has been stated that Osiris can run faster than this since at the time the Flash was Speed Stealing from him).
Superhuman Speed- Osiris is able to move at incredible speeds and is able to move so fast that he can seem invisible to the eye of the human being. Osiriss speeds is said to surpass that of even Superman. Osiris is also able to use this speed to increase the processes at which he thinks. This gives him a great advantage as he is able to become completely aware of his surroundings in a matter of seconds.
Flight- The power of Heru grants Osiris the magical ability to defy gravity. With this ability he is able to travel through space and through the atmosphere of the Earth at incredible speed.
A is for the strength of Amon, strongest of the gods. Osirisis empowered with Amon' nearly limitless superhuman-strength which is often compared to and rivals that of Superman. As such, Osiris's strength is of the highest level and is sufficiently vast enough that it enables him to lift/move unbelievably massive and/or heavy objects possibly on a planetary scale or higher with little effort. Osiris is so strong that at one point in time he was able to fight off the entire JSA.
Superhuman Strength- Osiris has the ability to lift well over 100 tons with minimal effort and has battled top tier beings such as Wonder Woman and also Superman. The limits of Osiriss strength are unknown.
Z is for the wisdom of Zheuti. The wisdom of Zheuti gives Osirisgreat knowledge as well as a photographic memory. Zheuti is actually able to speak to Osirisduring his times of need. The wisdom of Zheuti also makes Osiris omni-lingual and makes him a very skilled war tactician.

A is for the power of Aton, most powerful of the gods. This grants Osiris magic resistance and the lightning that changes Osiris. He has used the lightning as a weapon before, when he dodges it - allowing it to strike an enemy. Osiris has also stated that with this power also comes the "Wrath of Aton."
Magical Resistance- The power of Aton gives Osiris a resistance against magic and only magic of the highest order is able to harm him.

Osiriss healing factor is also of a godly level and is able to heal himself from almost all injuries in an incredible amount of time.
M is for the courage of Mehen which grants him an inner strength and confidence.
Invulnerability- Osiris is virtually invulnerable to all forms of harm. His resistance to harm is equal to that of Superman's but he does not share his weaknesses to Kryptonite or magic.

The Power of Isis
Recently Osiris has acquired the power of Isis which gives him the power over Nature as well as Telekinesis. The power of Isis also augments his already godly powers that are bestowed upon him by the Egyptian Gods.
Although Billy Batson and Osiriss powers are very similar, the differences between them are that Osiriss powers are derived from the Egyptian Gods instead of those of Greece and unlike Billy Batson Osiris very rarely reverted back into his mortal self.
High Order Magic: Although Osiriss abilities give him a resistance to most magic, magic of a High Order does have the ability to harm him. It would take a being however of extreme proficiency in magic however in order to harm Osiris such as the Spectre.
Lightning: As we have seen in the case of Billy Batson as well lightning has the ability to transform Osiris back into his mortal form.
Paraplegic: In his mortal form Osiris is paralyzed due to the torture he was forced to endure at the hands of Intergang.
Egyptology: Being a previous resident of Egypt (Khandaq to be exact) Osiris was extremeley proficient in the tales of the Egyptian Gods.
Multilingualism: Although the god like powers that run through Osiris give him the ability to be Omni-lingual we have seen Osiris speak in Egyptian as well as in English.
In Smallville, Osiris is the lover of Isis (whom in comic book history, Isis is Osiris' brother). However, in Smallville (and in egyptian mythology)Osiris was cut into a thousand pieces and got his spirit ripped from his heart. Isis spends a life time searching for her sole mate. Eventually, Lois Lane (controlled by the crazed goddess Isis) was trying to bring Osiris back to life through Clark Kent's body. If Isis succeeded in this, Osiris would bring Hell on Earth, since his soul was sent to the Underworld. Clark defeated Isis before this event happened.
