Golvarun

Golvarun is an aquatic-type Zoanoid that appears in the Guyver manga and anime. Its body seems to be mostly contained inside a solid shell, indicating that sea turtle genes were utilized during its optimization procedure. Its shell grants it significant protection from all conventional weapons and its organs can convert gaseous nitrogen from the air into a supercold liquid state. It can then spew the liquid nitrogen upon targets and instantly freeze them.

Golvarun was produced at Cronos' Relic's Point facility and was first field-tested during the Takeshiro Incident. It would later be put to effective use against the US Navy on X-Day.
