==History==
===Kamen Rider Kuuga===
Soon after the Me Group's turn begins with the Xu 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 Byran 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, breaking his horn in the process.
===Kamen Rider Decade===
====World of Kuuga====
At least one Xu·Zain·Da was part of a group of human-turned Gurongi created when they were exposed to N·Gamio·Zeda's miasma. Some were later absorbed by him in the last effort to defeat Kuuga and Decade. The remaining Gurongi died after Gamio was defeated.

Zain was one of a trio of Gurongi (with Xu·Goma·Gu and Me·Vagis·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.
