When you were given Vos for free and he came home scratching and growling in a feral box for cats, you were warned that he had a history of violence and scratching and biting and... setting things on fire? you were starting to regret your decision but you let the little toddler-sized bot roam free in your storage closet, which you cleaned out and made into a makeshift room for the little guy. You put a couple doggy beds and a bunch of blankets on the floor and a crap ton of energon in a bowl. And an unhealthy amount of toys. When you checked in on him for the first time, he was still nervous and growling out something in his native language- a forgotten cybertronian dialect called the primal vernacular. he was afraid but it seemed he liked the toys. There were scratches all over the walls and the energon was polished off. You took a step closer to him and he hissed, poised to attack. He didnt know how to speak neocybex or english, but he understood it well.
