Background / History
Aaron is the only known heir of the Gaius Family. His parents are frequently absent on unexplained journeys, while Jeans serves as his butler, guardian, and instructor. His family’s protection is extreme: six elite Auror-level guards secretly rotate around him, two at a time. Aaron resents this lack of freedom and seeks independence through his Diagon Alley beverage shop and secret System progression. 1 12
At age eleven, Aaron enters Hogwarts and is sorted into Slytherin. The Sorting Hat identifies his courage, tenacity, intellect, hunger for knowledge, unusually high Magical Energy, and exceptional potential. 18 Though born into an influential family, he befriends students across house and blood-status lines, including Harry Potter, Hermione Granger, Ron Weasley, and Draco Malfoy. 16 19
During his Hogwarts years, Aaron develops a public image as an academically gifted “model student” while deliberately concealing much of his actual combat power. He operates through Thoughtforms, trains in magic arrays and swordsmanship, investigates the Chamber of Secrets, participates in the Triwizard Tournament, and repeatedly interferes with Voldemort’s plans without openly committing himself to either Voldemort or Dumbledore. 200 307 372 474 513
Following the Battle of Hogwarts, Aaron acquires the Elder Wand and Resurrection Stone, then returns home before traveling through the Giant Tree into another universe. There, he rescues Tony Stark in Afghanistan and establishes a new identity in New York. 673 676 678
In the new world, Aaron becomes an alchemist and shop owner, later joining S.H.I.E.L.D. under negotiated conditions that preserve his independence. He gradually builds an organization of contracted vassals, gains authority over the Shadow Realm, develops the Mind World, and ultimately ascends to godhood. 702 870 899 1119
Appearance
Aaron is initially introduced as an eleven-year-old boy. By the time he arrives in the new universe, he presents himself as an eighteen-year-old traveler with an adaptable civilian identity. 1 676
- Frequently carries or is accompanied by Abe/Abei, his dragon companion.
- Uses ordinary clothing and a crafted Muggle persona to avoid exposing his magic in the new universe. 679
- Often conceals his true strength behind the image of a diligent student, ordinary diviner, or relatively capable human. 372 752
Personality
Aaron is intelligent, cautious, independent, and highly pragmatic. He dislikes being controlled by his family, Dumbledore, S.H.I.E.L.D., governments, or any larger faction, and he consistently negotiates to preserve his autonomy. 1 474 702
He is strategic rather than conventionally heroic. Aaron often helps others—including Harry, Hermione, Tony Stark, Bucky Barnes, Wanda Maximoff, and Peter Parker—but usually prepares contingencies, protects his identity, and refuses commitments he judges needlessly dangerous. 88 633 911 969 1130
Despite his self-preserving outlook, Aaron is protective of people and creatures he considers his own. He values Abe and Fawkes as family, assists friends in danger, assigns Ramon to protect the Delacour family, and retaliates forcefully against threats to those under his protection. 19 637 720 1083
Aaron is also ambitious. He seeks magical mastery, wishes to become Hogwarts Headmaster in the long term, builds personal domains and organizations, and eventually pursues the position of God of Magic. 485 607 989 1119
