Thought lost long ago, Power Core Combination has recently been rediscovered on Earth. It creates a new breed of powerful AUTOBOT warriors to destroy the DECEPTICONS! DOUBLE CLUTCH has always been a master of diversionary tactics. His entire team is built around the idea of confusing and disrupting DECEPTICON operations. The speed and noise of the RALLYBOTS alone is enough to strain any robot's sensors. Add to that all the electronic countermeasures built into the team, and the RALLYBOTS become the single greatest threat to DECEPTICON strategy. Power up for the ultimate robot battles! Your DOUBLE CLUTCH Commander vehicle is already a virtually unstoppable opponent in his vehicle and robot modes. But his strength gets increased five-fold when you convert him to Power-Up mode and convert his RALLYBOTS drone figures into his limbs! And the action doesn't stop there. With this Power Core interchangeable robot combination system, MINI-CONS (sold separately) and drone vehicles can attach to power up any Commander figure. Collect more packs and you can create tons of unique and fierce robot battler figure combinations! Five-pack includes DOUBLE CLUTCH, Street Racer Drone, Race Car Drone, Tuner Drone and Drag Racer Drone figures.
