Hi! This is my first fanfiction so let me know what you think!
This is set after Spider-Man: Homecoming and before Infinity War. BTW in this fanfic everyone who was on Cap's side of Civil War, except for Cap himself, was pardoned of any really bad punishment, and Thor and Bruce haven't gone to Sakaar yet.
As Peter Parker, wearing his Spider-Man costume, helped his mentor and personal idol Tony Stark/Iron Man put the last finishing touches on the billionaire's latest project, he felt a sense of pride helping Tony out. "Alright," Tony said. "If this bad boy works, we'll be able to cross over into different dimensions." Peter could hardly contain his excitement. "Who's going to be the first to test it?" he asked. "Whoever volunteers," Tony replied. "Excluding you, of course. Wouldn't want Aunt Hottie getting mad at us." Peter felt both annoyed at Tony's mention of his Aunt May and disappointed that he wouldn't get to try the invention out. "Fine," Peter said, "But you gotta let me try out your next invention." "Deal," Tony said. Tony called for everyone to meet him in the lab. "What's this thing?' Clint Barton/Hawkeye asked in curiosity. "The future," Tony replied with a grin. "So, I'll need no more than 5 volunteers to test this, and no less than 2." 5 hands went up, and Tony smiled. "Whoever just volunteered please step forward." Bruce Banner, Wanda Maximoff/Scarlet Witch, Scott Lang/Ant Man, Thor Odinson and Vision stepped forward. "Ok," Tony said, "Wherever this thing sends you, be EXTREMELY careful because it's never been tested before and there could be some minor time traveling." "Boss," F.R.I.D.A.Y, Tony's A.I said, "the machine's activated itself. Be careful and send the team through soon." "Thanks, Fri," Tony said, "I'll get right on it." As the volunteer team prepared to enter the bluish-purple portal that appeared, Peter suddenly shouted, "WAIT!" The portal started to collapse in on itself and everyone starded to back away, but Peter was getting drawn into the portal. "Mr Stark! Guys! Help meeeeeeeee!" Peter screamed as he was sucked into the portal. After he was completely gone, the machine stopped and the portal disappeared before anyone could go after Peter.
So this is Chapter one! I'm going to try to update this at least once a week. I don't really know what to have Peter come in contact with in the next chapter, so please comment on what you'd like to see him cross over into. This will also probably be an ongoing fanfic, and there will be one chapter for every dimension Peter falls into while trying to get home. Also, please PM me your comments and suggestions!
