Yellow

Kind and innocent boy, that is won't hurt a fly. Even though, he is 20 years old, but sometimes he acts like a child. He has grey hair, 5 meters lengthed tail, cat ears, red eyes and metered tongue.He has girlfriend, named Clover, who's age 20 years old now as well. They know each other for 10 years and their love was growing stronger and stronger. He is really kind and innocent creature, always ready to help and passionate in relationships. Right as his mother he has some unique attributes she has. He has much higher flexibility and regeneration. Also he can switch between 3 forms: First is cat-boy: his usual form. Second is half Yveltal: he gains wings and tail as Yveltal Pokémon has and can use them as extra hands. Also in this form he is much stronger, can fly and use magic: "oblivion beam" and "recovery" And third form is full Yveltal form. He becomes as his dad: fully Pokémon, and his abilities same as at second form.
