The currently ongoing Kamen Rider series, Zero-One, is helping itself to a truly bizarre crossover collaboration this weekend.

Toei has announced that the 38th and 39th episodes of the series will feature a special storyline around a very special guest star.

As Tokusatsu Network reports, the collaboration between Sony and Toei will see an Aibo pupper—from when the line was relaunched in 2017—will explore the childhood of Gai Amatsu (Nachi Sakuragi), the rival figure to show protagonist Aruto Hiden (Fumiya Takahashi) who suits up as the sinister Kamen Rider Thouser.

Kamen Rider Zero-One’s 38th episode, kicking off the Aibo storyline, airs this weekend in Japan.
