Planet Prince 2021 (Japanese: 遊星王子2021, Hepburn: Yūsei Oji 2021) is a 2021 Japanese tokusatsu science fiction superhero film directed by Minoru Kawasaki.

[1] It is a reboot[2] of Toei's Planet Prince franchise and the second theatrical film adaptation of the series.

Planet Prince awakens from his sleep, rescuing the bakery's daughter Kimiko from a desperate pinch and deciding to stay at the bakery.

As the planetary prince explored the earth, he interacted with the residents, occasionally replaced the top idols, and guarded the city from the alien invaders, the Turtans.

The impact of the crash, however, caused most of his memory to be wiped out, and he had no idea how to return to the fourth planet.
