Power up for the ultimate robot battles! Your GRIMSTONE Commander vehicle is already a virtually unstoppable opponent in his Commander Triceratops mode and Commander robot modes. But his strength gets increased five-fold when you convert him to Power-Up mode and convert his DINOBOTS 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.
