Doraemon: Gadget Cat from the Future is the US English adaptation of the 2005 anime that has been airing since July 7, 2014 and has aired a total of 52 episodes as of 2015. Since February 1, 2016 ,the US adaptation airs bilingually in Japan on Disney Channel Japan. This dub takes many liberties from the original Japanese version. Besides using the name changes that were used in AltJapan's English adaptation of the original manga, other changes and edits have been made to make the show more relatable to an American audience, such as Japanese text being replaced with English text on certain objects like signs and graded papers, items such as yen notes being replaced by US dollar bills, and the setting being changed from Tokyo to a small town located somewhere in the United States.

There is a tower that summons chosen people called "Regulars" with the promise of granting their deepest desires. Whether it be wealth, fame, authority, or something that surpasses them all—everything awaits those who reach the top. Twenty-Fifth Bam is a boy who had only known a dark cave, a dirty cloth, and an unreachable light his entire life. So when a girl named Rachel came to him through the light, his entire world changed. Becoming close friends with Rachel, he learned various things about the outside world from her. But when Rachel says she must leave him to climb the Tower, his world shatters around him. Vowing to follow after her no matter what it takes, he sets his sight on the tower, and a miracle occurs. Thus begins the journey of Bam, a young boy who was not chosen by the Tower but opened its gates by himself. They call his kind "Irregulars"—beings that have shaken the very foundation of the Tower each time they set foot inside it. [Written by MAL Rewrite]
