BULKHEAD
(Voiced by Bill Fagerbakke)

Every team needs its “muscle” and BULKHEAD is it. Designed primarily for demolition, BULKHEAD is a bull in a china shop, whether he wants to be or not. In battle, he’s your greatest weapon. Everywhere else… well, hide the breakables. He’s not overly clumsy, but he’s like a big overly enthusiastic dog who doesn’t know his own size or strength. BULKHEAD has a natural curiosity about humans and their culture. He’s especially interested in art, something that doesn’t exist on Cybertron. On some level the creative urge is an attempt to compensate for all the destruction—deliberate or inadvertent – that he causes. Problem is, most of his “creations” either fall apart, don’t look a thing like what he says they are, or are just plain ugly. Not that anyone would ever tell BULKHEAD that to his face.

Robot Mode Power: BULKHEAD is easily the strongest of the AUTOBOTS. That combined with battering ram arms make him the ultimate “Demolition Bot.”

Vehicle Mode Appearance: S.W.A.T. Assault Vehicle.

Character description from package "tech spec":  Super tough strong-bot

It's hard not to like Bulkhead.  Despite being huge and strong, he's the kindest, most gentle of the Autobtos and he always has other people's best interests at heart.  He's also a klutz.  That's why it's so terrifying when the Headmaster takes over his body.  Bulkhead regularly engages in wholesale property damage purely by accident.  With the Headmaster in charge of his body, will anyone be able to stop the tide of destruction?

Galactic Powers and Abilities:
> The strongest of the Autobots on Earth.
>  Rarely uses air torpedoes because of accuracy issues.
> Buzzsaw originally built to slice iron meteors.

Bibliography of significant appearances: One could argue that Bulkhead is the most featured character in the entire Transformers Animated series.  His character has been heavily featured in the following episodes: 
Transformers Animated Movie introduction, " Transform and Roll Out" parts 2 and part 3. 
03 Blast from the Past
07 Sound and Fury
09 Survival of the Fittest
10 Headmaster
19 Rise of the Constructicons
22 Autoboot Camp
25 A Bridge Too Close, part 1
26 A Bridge Too Close, part 2

Other Appearances:

In all of the Transformers mythology, there has been only one other character with the name Bulkhead.  A large green helicopter in the Transformers Energon series of 2004 (sorry, no character page yet).  In that series he was the elderly persona among Autobots.  Since some fans consider Energon to take place in the far future, perhaps one can consider these to be the same?  It's up to you and your personal "fanon."

In 2008, there the character was released as Voyager Class and Leader Class toys.
