The ESTF Ultra-Mech Robot Defender Unit-01 "Tranzor" is the titular mech of one of my fanfics, Tranzor ZXV. Piloted by Anna Coleman, Tranzor is the first in a line of experimental giant robots called "Defender Units", created by the Earth Safeguarding Task Force for the purpose of neutralizing global catastrophic risks. Meant to be Earth's last line of defense against all manner of threats, the project was eventually abandoned due to a mysterious incident. Tranzor would later be discovered in a junkyard(actually the remains of the base where Tranzor was being worked on.) in Sunset Ridge by Anna Coleman, who became its new pilot. Anna would pilot Tranzor in her battles against her rival, Stacey Hinkhouse and her new friend, Mitsy Adams.
In its debut, Tranzor looked exactly its [Japanese counterpart]. After being modified by Peg, it now sports Hello Kitty-like aesthetics, including a bow-shaped heat sink and a color scheme representing Hello Kitty's clothing. In Volume 2, it was repaired after its battle with Giga-Stacitsy and Robo-Harry in the first volume. It appears the same, except that its right hand is now black, larger and sports a golden ring decorated with small knobs on the wrist.
