- Thunderhead is an Autobot from the Dark of the Moon portion of the live-action film series continuity family.
Everything Thunderhead does, he does loud. As an artillery commander, he is an expert at raining down fire on enemies hundreds of miles away.
His partnership with Major Tungsten is easy — both of them are loud, and more than happy to drop a storm of explosive shells on the heads of unsuspecting Decepticons.

- Thunderhead transforms into a walking cannon with tracked legs that the Major can ride on. Thunderhead can also transform into a sort of armour suit similar to that of the Mechs in the Exosquad series. Major Tungsten can fit inside this mode and "pilot it". In humanoid mode, Thunderhead can hold the cannon from his walker mode as a rifle.
