How all started?

Some fellas were chilling out outside their house when they saw an UFO going down the river, when they all arrived, they noticed there was an unique masterpiece of humankind. It was Luther!, They invited Luther to the BBQ where they were doing that sunny day. Luther talked with the guys for a long long time. "When i was born, my parents needed to protect me by lefting me alone in the middle of the space inside an small metal sphere called "Gloomonia". After a few days i was able to talk and move properly, i knew i was a genious, my mind was full of information like if someone just put an database on it, so i modified that metal sphere to move out there until i reached an strange planet where other people used to live. I learned how to work on an abandoned workshop. I build a portal pistol called "Zapper", i called it like that because the first version of it make the curious noise of an electric zap. When i saw the first portal, i didnt know where will it take me but... i pass trough, i was so curious to see what will i receive on the other side. Once i passed trough it, i saw it, i mean... i saw it all, it was all clear, i saw me, in infinite possible ways, i think i passed there like... more than 40 years because when i came back, everyone on that planet where old except me. I lived there unimaginable things, i met myself unlimited times, but that's another story. After all that, something bad happened, that's why im here, the main thing is that i need to recreate a new version of that "Zapper" to go visit one of my infinite realities to help me, but first... can you pass me a little bit more of that juicy BBQ you gave me and one of those uhm... beers more please?" That’s when the fellas came with the idea of express those different realities to prevent loosing them, Luther agreed with that, he said that was an excelent idea so maybe someone will help him to earn some bucks to repair that Zapper by buying some expensive things on this new weird planet so he will get real help when he will see one of his realities.
