Created by a being known as “Anthro the Mortal” by using science and magic(and observing a little of Discord’s power and form) was able to Gene splice two species(and an octopus) into a vicious monster, the first of his kind. Abyss is Genderless due to having a mare and a male diamond dog but is considered a male due to him always listening to Abyssal. Abyss is able to dig through the earth and can spring his tentacle from the ground to grab his victim and pull them down into the earth. Abyss also has the unicorn’s horn so he is a quadruple threat, magic, strength, speed and terror. Now onto Abyssal Zone, yes she is a crystal pony, no she didn’t get involved with Sombra’s rule because she left the kingdom before that. But unfortunately due to learning of what happened to the empire the depressed Abyssal decided that she didn’t care and went to taking care of herself by manipulating stallions/mares of all ages and afterwards robbing them blind, but it didn’t change her feelings towards the friends she left back in the Crystal Empire to slavery and such. So later she went a little crazy in one of those in your head type ways and she went to the Everfree Forest to die, dying from starvation she was rescued by her new master Anthro and aided him in covert op missions right under Celestia’s nose. After collecting enough resources the two captured a diamond dog to start the first experiment of the first gene splicing, Abyssal willingly volunteered to be a part of the procedure, Anthro declined but Abyssal explained to her master that she was done being looked down upon ponies as being fragile and wanted to be looked up upon with fear and terror(plus she can easily control the monster on the inside), Anthro allowed her to be a part of it. Oh almost forgot she mainly used her magic on the ponies beforehand with the manipulation because it was such a transcending and hypnotic aura which is actually her skill, manipulation/transcending/hypnotism of the emotion known as love. Dirt on the other is the complete opposite of Abyssal Zone, he is responsible, caring, honest and everything in between. The reason Dirt is involved is because he was once Abyssal’s boyfriend, so at somepoint of the relationship Dirt realized what Abyssal does for a living(before Anthro) so he dumped her which drove the pony nuts from being unsuccessful, so she decided to kidnap Dirt and use him for the gene splicing experiment…for revenge. So now Abyss has three minds: his own, Abyssal who he mainly listens to, and Dirt who never listens to. Oh and one more thing Abyss has 100% defense by turning a part of his body into crystals. Abyss is now as old as…well I don’t know actually, but he is old but still acts close to a teenaged jock in the middle of a football game.
