Earth-3550 is a world where biological mutants don't exist... until Corvin came around. It's a futuristic society, littered with crime, cybernetic enhancements, and the control of the government running rampant.

Who is this Universes Spiderman? Corvin Castro - the only biological superpowered being. He's an anomaly in his own universe, considered a "freak of nature" - quite literally.

Who are the main "Villains" of this universe? Damage Control - Much larger and more dangerous than what is seen in the MCU. They work under the government, and have just as much power as the President himself. They've basically been given a task of "keeping the place clean". 

The recruit - or rather, *force*, criminals or their own workers into experiments, creating cybernetically enhanced beings like Vulture and Doc Ock. Vulture is their most successful, and is their main weapon of choice when attempting to capture and study Corvin.
