This is not official, it's some weird stuff made up by me and my friends
Luigi
Luigi was just some random guy who lived in the city of Detroit in the Outer Wilds until he found a magical vacuum cleaner at a garage sale. At first, he thought it sucked, until it made his landlord disappear. He joined a boxing tournament, planning to cheat with the vacuum, but was eliminated by Sonic before he could even take it out. He swore vengeance and went on a rampage across Detroit, causing over 50 million gold coins in property damage. However, he was soon apprehended by the local militia and thrown in jail for life.
