The Autobots' leader is the biggest, strongest, and smartest of them all. He's always awesome, whether in big-rig mode or as his blazing red-and-blue-armored self. His prime directive: to protect the humans from danger during the ongoing war with the Decepticons. You wouldn't call him 'cuddly', but he does care. He's just seen a lot of battle ... and he knows there's more to come.
