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!Before he became a team commander, STAKEOUT was considered a loose cannon by many AUTOBOTS. He often ventured out on his own, against orders, determined to win the war on his terms or not at all. Undergoing the Power Core process has mellowed him. He has learned that with power comes responsibility, and is determined to use his new power for the greatest good.Power up for the ultimate robot battles! Your STAKEOUT 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 PROTECTOBOTS drone figures into his limbs! And the action doesnt 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 STAKEOUT, Mobile Artillery Drone, APC Drone, Helicopter Drone and Fighter Jet Drone figures.
