Had their operation succeeded, Evolto would have disappeared alongside Build. However, Evolto avoided death by possessing Sento’s body instead! But something else has happened. Because Evolto’s genetic signature was removed from Ryuga’s body after he possessed Sento, he can no longer transform into Cross-Z. Even so, Evolto was still strong enough to take over Sento’s body. In a state where he can no longer transform into Cross-Z, is there a chance that they can still defeat him? (Source: kamenrider.fandom)
