An adopt from  NelsonNoir that has been available for 5 whole flipping years (seen here: https://www.furaffinity.net/view/24798060/), but apparently, nobody put a bid on the poor guy. Anyway, The setting is in a series called Pokémon Forever. The story listed in the "all" sub-folder for the series' folder group is this: "Pokémon Forever is a fan series created by me in which five Metwos, including a Shadow Mewtwo, set all human-trained Pokémon free, gave them more anthropomorphic forms, gave them the ability to speak, and declared war between Pokémon and humans. The Pokémon, of course, won the war. According to the terms of surrender, all human governments were dissolved and all humans in the world were transformed into a Pokemon of their own choice. Yes, each human got to choose what anthropomorphic Pokémon they would become. The Pokémon world now lives in harmony under the fair rule of the Council of Legendary Pokémon. However, some wish to disrupt this peace. But, luckily, there are still plenty of heroes, old and new, to stand in the way of these new evils." Z-dog's story is that he was once a human male who could use Aura named Lucas Kindly. Lucas was the only human who chose to fight beside the Pokémon in the war. He wasn't exactly outclassed by his Pokémon comrades, however, as he was extremely skilled in using Aura in combat, in a way that could probably make a high-level Lucario or Sylveon jealous (Yes, Sylveon can canonically use Aura to a degree. This is confirmed in the Pokédex entries for these games: X, Omega Ruby, Sun, and Legends: Arceus.). Certain people, based on their morality toward Pokémon, were given the privilege of being able to choose a mythical Pokémon as their new form. However, due to Lucas not only having high morality toward Pokémon, but being the only one to actually fight alongside them, he was granted the sole privilege of becoming a Legendary. Zygarde had been hit by a virus that left him permanently unable to utilize his 100% forme, so the five cores took on formes. Four took on 10% formes (with the virus rendering one doggo who would become known as Axel a shiny), and the remaining one took on a 50% forme. However, without a sixth core, they had 10% of the cells left over. So when they heard that Lucas was allowed to Become a Legendary, they quickly came to him with an offer to become a Zygarde core to take on the remaining 10% of the cells. He agreed and underwent the process. In the present day, he decided to become a superhero named Z-dog. He utilized his powers as a Legendary Pokémon and his powerful Aura abilities to fight evil. I'm planning on giving him a Lucario sidekick but I don't know what to name said sidekick yet. Anyway, I hope to expand on this universe and make it into a big project.
