Bulkhead

Bulkhead was an Autobot and a Wrecker during the war of Cybertron. Big, bulky, and not too smart, he was loyal to the core to Optimus and mankind.

Appearance
Bulkhead was a large Autobot who was five feet taller than Bumblebee. He was mostly a faded green color while parts of him were black. His eyes were blue and his head was silver except for a faded green part on the top of his head that looked like a helmet.

Time on Cybertron
Bulkhead was a key player in the war for Cybertron. He was a part of the Wreckers, a group of combatants similar to Earth's Marines or Special Operations Units.

The Great War
During the war Bulkhead became a member of the Wreckers, an elite combat unit dedicated to fulling missions that no one else would accept, where he met Wheeljack of whom the two developed a close friendship with each other where the two fought together in many battles alongside many others. In one unnamed battle, he and Wheeljack were left with no communications as well as possessing low Energon thus were surrounded by Decepticons; however Wheeljack managed to save the pair by tossing a grenade into a smelter causing it to explode and take out their enemies.

At one point he and Wheeljack had an altercation on Sandokan additionally Bulkhead personally witnessed an entire unit wiped out by weaponized Tox-En orchestrated by Megatron. He also developed a long-time rivalry with Breakdown, whom Bulkhead personally stated to have caused him many painful losses when referring to Miko "You have no idea the things he's done."

Eventually during The Battle Of Thunderhead Pass, Bulkhead joined Optimus' forces despite his love of being a Wrecker he decided to put his strength towards a more noble cause as he considered him to be 'the real deal' he later became a member of Team Prime where he presumably met Ratchet and Bumble Bee, however, he often pondered whether Wheeljack felt that he deserted him. At one point he and the rest of Team Prime experienced an end run on Polyhex.

Human encounter and the return of Megatron
Bulkhead followed Cliffjumper's signal with the other Autobots. He arrived with Arcee, Bumblebee, Ratchet and Optimus Prime on the scene. They searched the area until Arcee found one of Cliffjumper's horns. The team held a little funeral outside of their base to honor Cliffjumper and hoped for the best of being on Earth.

Optimus instructed Arcee and Bumblebee to retrieve Jack and Raf when they were spotted by Decepticons. Along the way, they were spotted by a third human, a girl named Miko Nakadai. After they arrived, Miko had already questioned Bulkhead on his appearance and personality. Optimus explained to the three that the Autobots were there to protect their planet from the Decepticons and feared Megatron's return.

Optimus explained that the Decepticons were on Earth with them because their planet was uninhabitable at the moment and stated that if Megatron returned, then things would be worse.

When Agent Fowler came, Optimus told the humans to hide so that he doesn't get them out. In the short conversation, Bulkhead broke one of Ratchet's devices, which enraged Ratchet. When Agent Fowler left. Bulkhead stated Fowler's big bearings for being a human. Optimus informed him that Fowler was concerned for the people on Earth. When Cliffjumper's signal came back online, Optimus went with his team while Ratchet remained at the base with the humans. In a decepticon mine, they fought vehicons and killed several of them. In their desperate attempt to find Cliffjumper, they were too late and escaped the mine before it blew up. They groundbridged back to base, where Miko asked if she could come next time. Arcee was close to yelling at her, but Jack took Miko away. Optimus asked Arcee what she saw and she told him that Cliffjumper was experimented on by the Decepticons. Arcee fates near the floor, which caused the team to try to help her. Arcee said she was fine, but Ratchet had to check her. He examined her and found a strange colored liquid on her hand. Ratchet scrapped it off her hand and told her to take a containment bath to avoid any strange things. Optimus assigned Bumblebee with Raf, Bulkhead with Miko and Jack with Arcee to accompany them to their homes. Bulkhead took Miko for a little joy ride on their way to the base. As the humans and Autobots came to the base, Optimus perpared to roll out with Ratchet. Optimus puts Arcee in charge and she questions him on where he's going. Optimus said he was going with Ratchet to investigate and they went off.

Eventually, Agent Fowler was kidnapped by the Decepticons and caused Bulkhead to save him while the kids stay at the base. Miko managed to follow Bulkhead and he spotted her by his side. He told her to stay quite but a Decepticon trooper spotted her. Bulkhead swiftly killed the trooper and realized that Jack and Raf came along too. They hop inside Bulkhead's vehicle mode and went to save Fowler. Troopers caught Jack and Raf, but Arcee and Bumblebee saved them both. When Bulkhead reunited with Bumblebee and Arcee, they went to save Fowler and escaped with the kids unharmed.

They returned to base, Optimus helped Ratchet with his arm. Optimus found out that the humans went on a wild chase to get Agent Fowler back and Bulkhead told Optimus it won't happen again. Miko protested and showed Optimus a picture of a vehicon, which she thought was a Decepticon plan. Optimus explains that if Megatron uses Dark Energon to revive Cybertron's dead, the zombie army will come to Earth and destroy it.

Optimus assembled his team and they prepared to fight against the oncoming threat. They killed vehicons and Optimus fought against Megatron. While Optimus and Megatron fought each other, the team was disabling the space bridge. Megatron shot Arcee when he came around after fight Optimus. Optimus escapes with his team back to base. Miko ran over and hugged Bulkhead's hand. Arcee was damaged, but she is still standing. Optimus makes a speech on how they will vanquished any foe that comes in their way and that they will stand for their home.

Masters and Students
Bulkhead was helping Miko with her science project for school until Ratchet was involved in assisting the kids with their projects, which left Bulkhead and Arcee out of the fun.

Scrapheap
Bulkhead went with Bumblebee through the Arctic to find nothing to bring back to base. Ratchet examined both of them and Bulkhead insisted that they were fine to Ratchet. Bulkhead and Bumblebee were forced by Ratchet to work while Optimus was out with Arcee in the Arctic. Bulkhead, Bumblebee, and Ratchet shockingly witnessed as Raf brought a scraplet over. Bulkhead and Bumblebee deployed their weapons and huddled near Ratchet. The scraplet made its way to Bumblebee but it was soon destroyed by Raf. Bulkhead explains that scraplets eat metal, especially living metal. It was clear that their mission was to get the Groundbridge working, after the scraplets had tampered with its Energon pipe, in order to save Optimus and Arcee from freezing to their deaths. Bulkhead tagged along with Miko in a bug hunt to search and destroy the scraplets but ran into complications as the lights in the room that they were in turned off, to which Bulkhead screamed frantically like a little girl. When the lights came back on, Miko questioned if Bulkhead did and Bulkhead tried to cover it up, but was soon jumped by scraplets. However, Bulkhead, Bumblebee, and Ratchet managed to survive through the whole ordeal, with the aid of their human allies, the GroundBridge was working. Bulkhead acted as bait and managed to lead the scraplets into the bridge where he successfully gets them to the Arctic where he tells his comrades to duck down as he did so himself. After the scraplets were frozen, Bulkhead informed Optimus and Arcee that he would invite them in but the place was a mess. Bulkhead went back to base where he was looked at by the humans and witnessed Miko screaming like a little girl herself after seeing a spider.
