Yuki Sato is going to reprise as Arata Kagami / Kamen Rider Gatack in Kamen Rider Zi-O Episode 37 & 38. It is confirmed that he is going to transform into Kamen Rider Gatack. He tells Sougo Tokiwa about the Hell Brothers.
Hidenori Tokuyama is also going to reprise as Sou Yaguruma / Kamen Rider KickHopper. He is seen along with Another Kabuto for some reason. He is on bad side once after that ending in Kamen Rider Kabuto TV Series?
Masato Uchiyama is going to reprise as Shun Kageyama / Kamen Rider PunchHopper. Kamen Rider PunchHopper is nowhere seen in the trailer of pics. But Another Kabuto is seen along with KickHopper. There are likely chances of Shun Kageyama being Another Kabuto.
Think of it. Shun Kageyama was killed by Sou after he turned into a Worm. So he shouldn't be existing. But what if the Time Jackers have turned him into Another Kabuto before he died?
