A Kiss Player is one of a few human females that, through a quirk of fate, gained the ability to fuse with giant robots and fight tentacle monsters. They first began to appear in Earth's population shortly after the defeated body of Galvatron streaked through the planet's atmosphere and devastated the city of Tokyo. Their ability is triggered via the titular kiss, and allows them to enter the bodies of robots engineered with ParasiTech technology. The aftermath of this process leaves them nude and quite soaked. As such, it may not be the most practical superpower available, even with the advantage of being able to go toe to toe with Cybertronians.
