Soon after the Me group's turn begins with the Zu no longer worthy to play, and when their first hideout got compromised by the police's smoke bombs, Zain starts acting on his own by attacking trucks and jabbing the drivers to death with his horn.
He overpowered Kuuga in both human and Gurongi forms when Biran intervened as Zain stole his turn. While Zain resumes his attack on large motor vehicles, Yuusuke manages to perfect his Mighty Kick to finally kill the rampaging Gurongi.

Zain was one of a trio of Gurongi (with Zu-Gooma-Gu (Ultimate Form) and Me-Badjisu-Ba) who were seen fighting Kuuga in new video footage that Tomoko Nozama found on the internet, along with other clips of past Kamen Riders, who are now known as urban legends.
