Radioactivity, Gamma rays, and infinity stones don't mix well. So when a young boy, no older than 2, stumbles across and comes in contact with them things don't end ideally.

The boy approached the table and touched the cool glove with the glowing stones and decided to try it on. Bad Idea. He got it snug as possible on his hand and suddenly screams and tries to remove it. It took him a while to remove it but when he did the stones were gone.

He began to panic and search for them but the only thing he found was a sheet of reflective glass.
When he looked at himself he noticed he looked different.

When before he had chocolate eyes and fluffy hazel curls that bounced on his head.
His left eye was bright red and his right a bright yellow.

This hands were different too.
His left was glowing bright purple
And his right was bright green.

His chest was glowing bright orange but only in one spot.

And the point directly between his collarbones was glowing a bright blue.

And then it dawned on him where to rainbow of glowing rocks went.

So he began to create. He created an entire universe and spread decoy Infinity Stones across the universe.

He then chose a time where he would place himself and did so just like that.

He started by creating who he will be and when and this were his results.

Name: Peter Parker

Origin: Frost giant who was sent to Earth by his father Loki for protection from odin. He was then adopted by Mary and Richard Parker who die when he's two and he is sent to live with his aunt and uncle. When he's 14 he gets bitten by a radioactive spider and gains spiderlike abilities. Shortly after aquireing his abilities his uncle dies. A few months after this Tony stark approaches him because he is in need of help by his 'alter ego' (tony doesn't know the half lmao) Spiderman. (Okay you guys know what happens right. Okay so all that will happen but with the underlying fact that peter is really the creator of the universe and a frost giant)

He decided that he was going to be 'born' in 2001 and so there he went

He also decided that he will only start to become to his full power when the spider bite happens.
