Ironhide was built at a time when armour was thick and circuitry was simple. He is the oldest of the Autobots, tested in thousands of battles, over countless centuries. He has been injured many times, but never deactivated. For every scratch and scar that he bears he has a tale to tell, and most of the younger Autobots are all too eager to hear them. Gruff, and sometimes grumpy, he is also naturally protective of the other Autobots. He is tough, rough, and nearly impossible to damage.
