Fan Casting “Test: R-Serum” in Unrivaled Spider-Man: An Dark Path of Illusions

In a secret Oscorp Industries, long after hours. Harry Osborn, shaken by recent events and haunted by loss, reviews classified research files labeled R-Serum a volatile formula designed to enhance human physiology beyond natural limits. Ignoring warning logs and failed test results, Harry finalizes the serum using his own modified equation, convinced it’s the only way to protect himself and prove his worth. Alone in the lab, he injects and then drinks the R-Serum, his body convulsing as veins glow faintly red. As alarms flicker and the lights dim, Harry steadies himself…and smiles. In the reflection of the glass, his eyes briefly flash crimson.
