Defeated by: Double HeatMetal's Metal Branding

After being fired from her position as a designer of the Windscale clothing line, Marina acquired the T-Rex memory the same time as her boyfriend Yousuke, intent on getting revenge. In her Dopant form, the T-Rex Dopant can cause massive shockwaves with her roar. When Yousuke dissappears without a trace, Marina uses Shotaro to find him for her, making her move to silence Yousuke after Double defeats him in the form of the Big T-Rex ( ビッグ・ティーレックス ), a robotic Tyrannosaurus body constructed from debris. When Shotaro learns the truth, Marina fakes symphany before attempting to kill him before Philip arrives. After a long fight, Double defeats the Dopant and saves Marina's life before giving her to the police.
