“	In the beginning, it was just me and sis. And it was fine. But I wasn't satisfied. So I made more. I created the world. But I didn't stop there. No, no, no! I got the bug. So I -- I kept creating. I made... other worlds. Different combinations, scenarios, characters. Different versions of the same characters. You know my -- "my other toys."	”
	— God in Galaxy Brain

Trivia

• Mary Winchester was trapped in Apocalypse World with Lucifer. However, Lucifer managed to escape in War of the Worlds.
  • She and Jack were trapped in Apocalypse World together from The Bad Place to Exodus before returning to their universe.
• Virgil is the first and longest character to be trapped in an alternate universe.
• The French Mistake is the only known universe without magic. A Goblet of Blood still works there though and can reach someone in the Main Universe. Additionally, the magic in the Bad Place is incompatible with the Main Universe as seen in the fact that the magic that the alternate Kaia used to open a rift did not work for her in the Main Universe to return home.
• While using Kaia's powers in an attempt to locate Mary Winchester, Jack sees windows into several different realities, one of which appears to be a paradise.
• The Apocalypse World is the most recurring alternate universe.
• Season 13 featured the most alternate universes and the most appearances of alternate universes. It also has several rifts open between the universes throughout the season.
• In Wayward Sisters, a rift was open between the Bad Place and the Main Universe for a few days. As a result, monsters from that alternate universe crossed over into the Main Universe. Though several were killed, Sam suggested that more monsters may have made it through before the rift closed that aren't accounted for.
• Despite Dean having been to multiple alternate universes, when the Winchesters use the Demon Tablet Alternate Reality Rift Opening Ritual to reach Apocalypse World, his hair is enough of a guide to not end up in one of the other universes he has been to.
• The Alternate Kaia is the only one who has managed to open a rift between universes whose means of opening it have not yet been revealed, as Michael and Lucifer, the Winchesters, Castiel and Rowena, Diego Avila, Yokoth and the alternate Kevin Tran all opened their rifts through a powerful spell and Jack opened the rifts through his own innate power. 
• Alternate Michael has stated in Nihilism that the alternate universes are God's failed drafts. However, this is unconfirmed and may simply be Michael's bitter belief instead of actual fact.
  • When Sam asked God about the alternate realities, God dismissively admits that he found the alternate universes to be boring but at the same time God did seem offended when Sam asked him if what Michael said is true, indicating although God doesn't have much liking to the alternate universes, he doesn't actually consider them failures.
