Pokemon the Movie: I Choose You (Manga)

As the twentieth film in the series, Pokemon: I Choose You! returns to origins of the Pokemon series when Ash first met Pikachu!

When Ash Ketchum oversleeps on his 10th birthday, he ends up with a stubborn Pikachu instead of the first partner Poke'mon he wanted! But after a rocky start, Ash and Pikachu become close friends and true partners—and when they catch a rare glimpse of the Legendary Poke'mon Ho-Oh in flight, they make plans to seek it out together.

Trainers Verity and Sorrel join Ash on his journey, and along the way, they meet the mysterious Mythical Poke'mon Marshadow. When they near their goal, an arrogant Trainer named Cross stands in their way. Can Ash and Pikachu defeat him and reach Ho-Oh as they promised, or will their journey end here?
