Okay assorted headcanons about the Default Minecraft Skins (+Herobrine) now that I'm well rested and headache free let's gooo
-Steve (he/him) and Alex (she/her), being the first and the second first people to arrive to the world, are besties. Any time Steve goes mining he asks Alex to come with him so she can watch his back and make sure nothing sneaks up on him while he's on the hunt for diamonds.
-I thought Alex and Ari (she/they) looked really similar so they're sisters now. Ari is a little younger than Alex and far more calm and sweet, content to stay home and welcome anyone over for cookies and milk instead.
-Efe (ze/zir) is a wealthy executive of a potion making company, hence why ze seems to have a more fanciful appearance with gold jewelry and such. Ze is also a little self-absorbed but not really intentionally malicious.
-I made Sunny (he/him) huge because I just know if I didn't then I'd hate him on account of his haircut alone. He needed something positive to balance out having a bowl cut. Oh yeah and he's kind of the village protector due to have big and strong he is. He's a very no-nonsense type.
-Makena (she/her) is a librarian, because the yellow sweater just reminds me of librarians. She's sweet like Ari but can actually appreciate Alex's idea of "fun" too.
-Speaking of Makena and Alex, they're girlfriends.
-Kai (he/they) is the guardian of a nearby Nether Portal. Both so they can fight back any mobs that attempt to escape, but also to keep anyone that's disqualified from going to the Nether out.
-Being disqualified from going to the nether essentially means that the village leaders just don't think you're prepared to brave literal hell. In order to become qualified you have to get the strongest possible armor, weapons, and potions that are available in the overworld. This rule is basically just to prevent the amount of Nether-related incidents.
-(That being said, it's still 100% possible to make your own Nether portal elsewhere. It's still illegal and probably not a great idea but it's not like they can stop you.)
-So I've decided that I'm sticking with the idea that Herobrine (he/him) is a shapeshifter. His true form is incomprehensible to most mortals so he usually goes around taking on a slightly altered appearance of the first person he's ever seen- which happens to be Steve. They do at least have enough differences from each other (y'know, aside from the eyes) to still be distinguishable though.
-Herobrine comes off as cold and standoffish at first but he's actually a bit of a hopeless romantic, literally falling in love with a new mortal every few years and having kids with them. His mother ribs on him for this.
-You still shouldn't get on his bad side though. He's still Herobrine, even if he may not attack first anymore.
-IS White Eyes' (she/her) son. White Eyes is far more hands-off when it comes to mortals though, and is far more content with watching them from a distance. She's not seeking to harm anyone, just finds mortals interesting to watch.
-As of right now my notes states that Zuri (they/them) is a Library Assistant (probably Makena's assistant) who wishes their life was more interesting while Noor (he/she) is a traveler who's curious to a fault. I'm not sure if either of these are going to stay for now though, because I'm not sure what to do with th-
-Wait what if Zuri sometimes takes breaks from their job to travel with Noor, in the hopes of getting more interesting life experiences under their belt. Maybe that. Maybe they're friends. Yeah, sure.
