In retrospect Kamen Rider Gaim Arms Change Series. This was something during its time. It really was faithful to the show's fruit armor gimmick and whoever thought up of it in Bandai or PLEX deserves a raise.
Also the Ranger Keys from Gokaiger were genius. Great way to commemorate the franchise and highly collectable alongside a simple gimmick that changes it from figure to key.
One more I would like to add are the Tomica Hero Rescue Force and Rescue Fire vehicle and robot toys. It felt like the perfect mix answering the question what if Hot Wheels, Thunderbirds, and Super Sentai robot toys merged into one franchise.
