What If... Beast Never returned to the X-Men
Beast becomes a wrestler and meets up with a fresh Peter Parker. Peter recognizes the fact that Hank is enhanced and their high IQ's cause an instant friendship. Hank and Peter keep eachother's secrets. When Peter's uncle dies and Peter learns his hard lesson, Hank is doubtful at first, he then reveals his inner crisis: He fears humans. Peter nodds and tells him that everyone is afraid, Peter's afraid. Only fools are fearless. Brave is when you act in spite of fear. Hank and Peter stick together, but Peter's cover is soon blown when Aunt May recognizes the abilites of "The Sweet McCoy boy" that her Peter hangs out with. The X-men take Peter and Hank in. The power increasing do-hickey is never invented.
What If Spider-Man stayed Pro-Reg
Peter confronts Tony with his doubts and thoughts, and Tony promises to have Clor dismantled. Following through, Tony explained that he needed the power of a god in a face people could believe in. the Secret Avengers had Hercules, a hero of epic literature. the Mighty Avengers may have had Ares, but no one liked him or trusted him. Peter promises to look into the problem and analyzes the samples of Thor's DNA, Ares' DNA, and even Hercules' DNA (the last was the easist to obtain). That was when Peter found it... the genetic markers of a god. from it they managed to create several animal gods (injecting the markers into animals).
Finally Peter confirmed that the serum was ready to test on humans. Tony said he didn't want a fleet of gods, he couldn't trust that many people. He wanted someone he could trust with that kind of power, someone who would act more responsibly because of the power he possessed. Tony gave Peter a significant look. After talking it over with MJ, Peter agreed to the process.
After he was injected he started to convulse, his vitals going crazy. eventually it looked like he had died on the table. then his eyes opened with light pouring out of them the restraints snapped and Peter floated into the air and was surrounded by a cocoon of light. an hour or so later he emerged. the lenses, top, and and lower part of his mask gone so that his hair, his chin and mouth, and eyes were visible. his eyes were pouring light at first, his hair was now whispy and white. the waldoes were gone from the back of his costume, in their place was a cape made of long flowing strands of webbing.
His strength was magnified to where he could easily fight against hercules, his Spider-Sense could now give him clear visions of possible futures, he could form web-constructs at will that would work in any way he wished. he could fly, and he could fire bursts of energy (the same radioactive energy that was responsible for the spider). Gone was Spider-Man... now stood Spider-God (Not Peter's choice of codename)
What If... Peter Re-Registered.
Peter joined with the resistance halfway through the war. What if, at the end of the war, spider-man re-registered. I think Tony would have put him in charge of Camp Hammond over Hank, which would, eventually, through a monkey wrench into everyone's plans. He won't cover up MVP's death, which would pre-empt the KIA crap, which keeps the Counter-Initiative from actually breaking away (especially since Peter banned Gauntlet from using the New Warriors as a label for poor performance). The Initiative becomes more effective. during WWH Peter makes sure that the Initiative kids stay in their barracks (being still young enough to remember how a teenager thinks). Cloud 9 developes her powers further (Peter manages to stabilize the ship that Hank decided to crash, while Cloud 9 keeps it aloft with her powers). However, during the SI, Peter turns out to be a Skrull. At the end of SI he comes out of the ship with everyone else... AND BEN REILLY
What if Magneto had chosen Xavier's path instead? What if Magneto chose to try and make peace between humans and mutants? Would there have been less hatred between humans and mutants? Would Xavier's mission had been that much easier? Or would things had been just as hard or perhaps harder?
