Monique learns from Major Hicks that a bizarre new life form was created via genetic engineering, and was now left abandoned in an old laboratory in Brazil. She convinces her allies in H. E. A. T. to go and investigate, and they soon discover that the creature is actually a DNA absorbing beast known as the Mimic, which can, as its name suggests, take on the exact physical and behavioral attributes of any living creature that it comes in contact with. The Mimic thus imitates the appearance of all of the H. E. A. T. members in turn, and paranoia reigns as everyone in the group must continuously be wary of each other as they search for a means of destroying the creature, since nobody may be who they appear to be. Finally, the Mimic imitates the size, appearance, and power of Godzilla [so much for the law of conservation of mass!], and the two Big G's battle it out, fighting each other to a standstill in the process.
