Tiara Borg is the fourth active Gerrok Techadroid Borgs, created when Gerrok Card 02 infects a tiara. Using the tiara on her right shoulder like a boomerang, Tiara Borg can digitize a woman's love and extract it. Her left arm has the power of Gerrok in it, allowing Tiara Borg to create energy spheres from her nails. Tiara Borg becomes a follower of Melissa, who attempted to protect her in order to preserve Gerrok's data despite Klez seeing the Gerrok Techadroid Borgs's data gathering to be useless. However, Tiara Borg ends up being destroyed by Spy Armor’ Gorilla Spy Ranger.
