Grimlock and the ambassador's son, Daniel, are accidentally transported to another dimension where magic rules supreme on a planet called Minonia. Saved from a barbarous band of thugs, Daniel and Grimlock dine alongside their savior in his castle and learn of the Red Wizard and his plight against Minonia's tribal bands. Little do they know their rescuer is not who he appears to be. Back on Cybertron, the Autobots must decipher some ancient hieroglyphs in order to rescue Daniel and Grimlock.
Grimlock's New Brain
Grimlock turns into a genius after shutting down a power core gone critical. That intelligence will come in handy when Galvatron gets his hands on some anti-electrons--a substance capable of scrambling Autobot circuits. The last remaining source is within Unicron's decapitated head, which is floating in space. It's a race to Unicron, where both Autobot and Decepticon alike will have more to deal with than just battling one another.
