Origins: In the aftermath of the Battle of Sokovia, the Avengers uncover Hydra's most audacious and blasphemous experiment: Project Chimera. This initiative attempted to artificially create the ultimate weapon by splicing the DNA of Tony Stark (for his genius-level intellect) and Thor (for his Asgardian power and longevity). Deemed a failure with only 12% viability, the project was scheduled for termination. However, the soulless "husk" unexpectedly awoke, displaying terrifying power, and escaped containment, vanishing without a trace.

The Protagonist: The being is Griffith, a young man with silver-white hair, piercing blue eyes, and an ethereal, calm demeanor. Unbeknownst to everyone, the body is inhabited by the consciousness of an 18-year-old orphan from another reality, placed there by the One-Above-All (appearing as Stan Lee) after his death. Trained in the mystical arts by the Ancient One at Kamar-Taj, Griffith has mastered powerful magic, including the ability to create mirror dimensions and open portals. He is a prodigy, acutely aware of his unnatural origin and the weight of his potential.
This is an AU. and this not a universe 616.
