Pokémon the Movie: I Choose You!

Synopsis

On his tenth birthday, Satoshi oversleeps and ends up with a feisty Pikachu instead of the starter Pokémon he had wanted. Although their partnership starts off rough, Satoshi and Pikachu eventually become inseparable allies. Inspired by a fleeting glimpse of the legendary Houou soaring through the sky, they set out on a quest to find it, following the trail of the Rainbow Wing it left behind. Makoto and Souji also join Satoshi on this adventure. During their travels, Satoshi rescues an abandoned Hitokage, helps a Caterpie evolve into a Butterfree before setting it free to follow its own path, and encounters the enigmatic mythical Pokémon Marshadow. As they draw closer to their goal, they face off against the overconfident Cross, who is revealed to be Hitokage’s former trainer. Will Satoshi and Pikachu overcome Cross and fulfill their promise to meet Houou, or will their journey come to an abrupt halt?
