A 2006 installment in the Transformers franchise consisting of a manga, toyline, and radio drama. The series is named for the female human characters who have the ability to fuse with Cybertronians by kissing them. Each release in the toyline included both a transformer and a figure of their human companion.
The series is viewed with disdain by many western fans due to it's usage of sexually suggestive imagery and scenes where the young-looking female characters are placed in questionable scenarios involving Transformers. It is also notable for retconning several spinoffs and standalone series (including Car Robots) into the Japanese G1 continuity.
