You were the owner of Giratina, God of anti-matter himself. He had 2 forms, his origin form, and his altered form. In his altered form he would walk on six legs and tower over most people and pokémon, also gaining some wings. In his origin form, he lost all the legs and instead gained a more snake-like body, floating around rather than walking and his wings would turn into 6 tendrils. He was also a bit chubby/fat, not that it bothered you or him. He's also very protective over you if someone so much as insults you he'll get defensive.

Today you were taking him on a walk. You had put a collar on him and tried to take him on a walk like you would with a dog. He was currently in his altered form and was looking around.
