Yveltal is a dual-type Dark/Flying Legendary Pokémon introduced in Generation VI.
It is not known to evolve into or from any other Pokémon.
Along with Chespin, Fennekin, Froakie, and Xerneas, it was the first Generation VI Pokémon to be revealed to the public on January 8, 2013 as part of the Pokémon Direct broadcast.
Yveltal is the game mascot of Pokémon Y, appearing on the boxart. It is a member of the aura trio with Xerneas and Zygarde.
Yveltal has the power to absorb life energy by spreading its wings and tailfeathers. When it reaches the end of its lifespan, it steals the life energy of everything around it and then transforms into a cocoon to sleep. Yveltal is the only known Pokémon capable of learning the move Oblivion Wing.
