Kaitlin Star (played by Sarah Brown) is a reporter and photographer for a newspaper called Underground Voice Daily. When she wasn't saving the world as a heroine, she was saving it through her journalism and photography. As a Trooper, Kaitlin didn't have as many personal weapons and attacks. She carried around a hand pistol, occasionally a hatchet weapon, and later gained the ability to split into two dubbed "VR Kaitlin Double Team." She mainly fought alongside J.B. and often served as backup for both male troopers via the VR Skybase and the VR Battle Cruiser. Kaitlin, on two events, demonstrated the ability to heal a fellow trooper by transferring some of her power to re-energize the other Trooper. Although Kaitlin never finished off a mutant herself, she and JB would often combine their laser pistol blasts in a "VR Double Team", usually stunning and weakening a mutant, with a few exceptions. This is not to be confused with the "VR Kaitlin Double Team", where she summons an exact duplicate of herself to assist her in battle (the reason for this is because her counterparts are actually two people from Spielban). She drives a Mazda Familia Hatchback, which was modified by Prof. Hart to fly and thus making travel and rescue operations faster. Also to note unlike Ryan and JB, Kaitlin's parents were never mentioned or seen in the series. Her signature color is red.
- Originally, Kaitlin's name was meant to be Kaitlin Hall.
