Ahem. Here's the second part of the anniversary post.
Sorry for taking a while to work on this, but better late and well written than early and sloppy.
Merida is the original... Well, Merida. sure, there's many variations of her throughout the multiverse, but there's only one that's known as the creator of the WolfVerse and it's similar Multiverses, such as WolfVerseSwap. As this is the original timeline, the first one out there. Whenever Merida isn't in UnderWolf she's often alongside her sister Pastel, guarding the multiverse. She's one of the few Meridas who remains in her AU over exploring the multiverse(s). Despite this, she's more knowledgeable of the multiverse than anyone, even Pastel or Ink.
Blaze is a Merida from WolfSwap, specifically a genocide timeline. She managed to get to the surface, and after a long time of being pretty much a bounty hunter, she came across the Bringers of Chaos, formerly Nightmare's gang, and hasn't gone back to her AU since, residing in Nightmare's castle. She enjoys going on any sort of mission, be it causing chaos or negativity in a AU or fighting with the Guardians of Peace, she always loves throwing herself into a fight.
Cherry is a version of Merida from WolfFell, a Pacifist timeline. She started traveling across the WolfVerse when a particular glitch occurred through the WolfVerse, causing many different characters to be thrown into one place. Cherry was intrigued by the idea of other AUs like hers, and learned how to teleport between AUs. Unfortunately, one day her travels were stopped short, and noone knows what happened to her...
Blossom is similar in appearance and personality to her counterpart Cherry, although she learned about the WolfVerse by Blaze coming across her timeline. Since then she's been traveling through the AUs alongside the Bringers of Chaos.
Pastel is the leader of the Guardians of Peace, alongside her closest friend Light. She guards the WolfVerse against the Bringers of Chaos, specifically her arch nemesis Glitch. Monochrome used to be her Apprentice. She knows about almost all of the AUs, and can create her own with Merida's help. Unlike Ink, Pastel used to have a SOUL, until it was destroyed by Error.
Monochrome was the Merida of X-Wolf, and she used to be a member of the royal guard, alongside her brother Fade. That is, until her AU was corrupted by Glitch, with her and her brother being the only ones to manage to escape the crumbled AU. She used to be in the Guardians of Peace, with Pastel as her mentor, until she was forced to choose between her mentor and brother, or be with her SOULmate and retain balance in the WolfVerse. She eventually chose to change sides to the Bringers of Chaos.
Light is Dark's sister, the Goddess of Positivity. Unlike the other AU Meridas, her fur is made of light, with her brother having fur of darkness. After her brother ate the negative apples, an attempt to protect his sister, she fled DreamWolf and never came back to that AU since. she came across Pastel, and the two formed the Guardians of Peace.
Moon, a swapped version of Light, is the Goddess of Negativity alongside her brother Sun. She can change between being corrupted or not at will, and the apple incident never occurred in her AU. She's one of the strongest Meridas, both mentally and physically especially while corrupted. She's able to travel through dreams or nightmares, and she can easily interfere with the course of them.
She is a Merida from a unknown, unfinished and destroyed AU, being Pastel's first AU. All the characters were all destroyed by their creator save for one character... Gold. Her SOUL was glitched into a timeline of UnderSwap, disobeying the barrier and causing many glitches in the UnderVerse, as she didn't belong in that multiverse. This eventually caused other AU characters of the WolfVerse to be glitched into that timeline, even several outcodes.
