a Japanese Transformers franchise which began in 2006. By virtue of being the only Transformers toyline and fiction released in Japan by Takara between the conclusion of Cybertron and the live-action movie, it was also effectively the main Transformers line in the country for that time. It takes place in the Generation 1 cartoon continuity, specifically in the five-year milieu between The Transformers: The Movie and Transformers 2010.
The series derives its name from its (controversial) gimmick, which involves Transformers getting "power-ups" when they are kissed by human girls - the eponymous "Kiss Players" - who fuse with the robots and share their adventures. Although this plotline may seem like a shift in demographics to little girls, it is said that this line was aimed at a much older (and creepier) adult male audience. Indeed, the toys bear an "ages 15 and up" warning, and the subject matter of the accompanying manga is far from child-friendly.
