CRANKCASE didn't start off as a bully. He started off bitter, mean and small-minded, and the strength granted by the Power Core process made him capable of taking his misery out on others. His few moments of happiness all occur when he uses his incredible might against someone unable to fight back. Then he's right back to being miserable.
Power up for the ultimate robot battles! Your CRANKCASE 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 DESTRONS 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.
