YDevil

A large, yellow, amorphous creature stands in a fiery landscape as a small, bird-like Pokémon flies toward it; the bird lands on the creature's shoulder, then the scene cuts to a small, blue and red robot-like Pokémon falling, followed by a young girl with short dark hair smiling and holding a device, then a black silhouette of a creature flying upward against a glowing sky, and finally a large, white, rock-like creature erupting from the ground in a burst of fire and debris.
