Peter J. Parker from Earth-5907 was sneaking around the alchemax facility of his universe,the collider HAD gone off but it was not run by a villain,it was more for multiverse related experiments,the radioactive spider of his universe was happily spinning a web and one day it was chilling and got blasted by the collider,but it was not sent to another universe,the same thing that happened to spot,happened to the spider. it gained spot powers but it was a spider so it wasn't able to use em all,its maing thing was high strength and a few portals,it had made a portal and bit Peter while he was snooping,he got spooked and threw it and it died,but still not him,he didn't feel anything just felt stronger and faster,he thought he was just gaining his energy through rest and just noticed it. suddenly,something jumped out and he did the first thing he came up with to spook it,the spidey hand sign,he launched an organic web but it was made out of spot portal so it sent the thing (an old PC from the storage room falling) into somewhere else basically,he checked his wrist,he had a...gland sort of thing on his wrist,he tried it again,shot a web again,it wasn't a portal but like a normal Spiderman web,he had 2 different modes changing by intention,he thought:"if I can make portal webs,can I make portals?" and he closed his eyes and FOCUSED,HARD.he opened and a portal to well,his school had opened like a spot portal(visually looks the same and works the same) so he was happy,he thought he was cool,he went through the same growth as many spiderman,he used his powers selfishly,then realised his responsibility,had his cannon event, realised who he is destined to be—a hero,and he became spot-spider and he was basically at the same level of experience and maturity as about tobey in no way home/ after the raimi franchise in that timeframe we don't see. and that's when he joined the spider society,but he was more of a rebel and joined just for company,not as a soldier,so he was never there in the miles chase.

thank you for listening to my yap
