In the alternate universe you've described, where Otto Octavius has swapped the bodies of Gwen Stacy and Angelina Brancale, it seems that Octavius is quite the mastermind with a grander scheme in play. Given that this is a hypothetical scenario with your own set of rules, here are some potential experiments Dr. Octavius might plan to do based on his character's background and typical motivations: 1. Mind Control: Octavius may attempt to harness the effects of the Green Goblin's formula that is affecting Gwen's (now inhabiting Angelina's body) mind. He could be trying to develop a method to control her aggressive tendencies and utilize them for his own purposes, potentially creating a henchwoman or a pawn in his conflict against superheroes. 2. Body Enhancement: Seeing the increased strength, speed, and durability in Gwen's original body (now inhabited by Angelina), Octavius might be interested in understanding the Green Goblin's formula further. His experiments could aim to replicate or even enhance these abilities, perhaps to improve his own mechanical appendages or create more super-powered beings under his control. 3. Mind Swap Perfection: The initial body swap might have been a test for a larger experiment. Octavius could be refining this body-swapping technology to use on a wider scale or to ensure success when he attempts to swap his body with Spider-Man's as part of his ultimate plan. 4. Psychological Studies: With Gwen's psyche being affected by the Goblin's serum, Octavius might be conducting psychological experiments to study the effects of such toxins on the brain, possibly to develop his own psychological weapons or antidotes. 5. Regeneration and Healing: If Angelina's new body (originally Gwen's) has gained some regenerative abilities due to the Goblin's formula, Octavius could be looking to unlock the secrets behind these capabilities to either heal his own health problems or create regenerative treatments. 6. Power Transfer: Finally, he may be looking for a way to transfer the enhanced powers from one body to another without the need for the serum. This could allow him to gain superhuman abilities without compromising his own mind or relying on an external substance. These are speculative possibilities based on the characters' histories and typical comic book science fiction tropes. How such experiments would actually play out would depend on the specific rules and narrative direction of your alternate universe.
