(based on Nick Fury's genetic sample). Banner mistakenly believed he solved the formula and tested on himself, however the process created the Hulk for the first time. After that incident, Richard Parker went to see his wife and baby Peter outside the research facility; Hulk destroyed the facility, the explosion resulted Peter's parents being injured but survived the incident. Hulk's humanity was only awakened after seeing baby Parker and reverted back to Banner. Fury had Banner arrested.

Eddie was a student at ESU, and showed Peter their 'inheritance' is a biological "suit" that could cure a person with cancer. Peter took a sample of the suit, but spilled some onto him, which formed into a black suit. When Peter raced after an armed robber, the suit took a turn into something that of a monster. Recollecting the death of Uncle Ben, Peter lost control and fell off a building onto electricity cables. Peter returned to ESU where he confronted Eddie and revealed his secret identity. He destroyed the rest of the formula. Eddie pulled another flask from the storage, and transformed into Venom. He tracked Peter down at Midtown High]] and they battled each other out.

Peter's home was somewhat of a boarding house for young superheroes. Johnny Storm was experiencing emotional issues due to the loss of his father. Coincidentally, Bobby Drake/Iceman parted ways with the X-Men and couldn't stay with former teammate Kitty Pryde. Aunt May welcomed both Johnny and Bobby to stay at the Parker residence until their issues improved. Much to Peter's surprise and relent, his home was now a superhero powerhouse.

Based around the ultimate universe, but with a mixture of mainstream universe and the cinematic universe, starring Drake Bell as Spider-Man teaming up with four other heroes Nova, Luke Cage (Power Man), White Tiger, and Iron Fist alongside Nick Fury to become the "Ultimate Spider-Man".

Peter even has tapes and memories based on that life. One of the writers did clarified on how Parker's parents were merely injured and not really dead, however, the details of the events were still unofficially resolved.
