Dunkan Bulk, also known as “The Behemoth”, is a member of the Alpha 1 Team.


Early Life

Dunkan Bulk was created in the Assembly Tower many years ago when Hero Factory was first founded and built. After undergoing training and being fledged a full Hero, he and Jimi Stringer were selected to become members of the Alpha 1 Team, as they had met the expectations of Preston Stormer. On one mission, they traveled to Almaak V and solved the mystery of Almaak IV’s disappearance. The Alpha Team later battled Cornelius Zo and his army of Tiger Ants, who were menacing a city. Bulk drove a tank, the Crusher, and caused the Tiger Ants to flee. The group also captured a notorious space pirate.

Bulk participated in the TV show “Dancing with the Heroes”, and was paired with a woman named Tina. His dance moves caused massive screaming and several injuries.

Rise of the Rookies

Recently, the Alpha Team was dispatched to guard a shipment of C-4000 explosives which was being attacked by XPlode and Rotor. When an abandoned Rotor threatened William Furno, Bulk offered him help only to get turned down. When Rotor escaped, Bulk returned to the Assembly Tower.

Bulk and the Alpha Team accepted a radio interview with Hero Factory FM, where Mak Megahertz talked to them about their battle with Cornelius Zo and gave him a brief recounting of the event, before being called off to another mission.

Clean -up

Soon after the mission with Rotor, Bulk and Stringer were sent to clean up the destruction caused by XPlode and Rotor at an Explosives Plant on Lemus 2. Shortly thereafter, the Call Center received a call on their hot-line and Nathaniel Zib sent Bulk and Stringer to defend Penitentiary 1331, a prison under construction on Tantalus 5, from the henchbot Corroder. During the battle, Corroder dropped a load of metal girders on Mark Surge, who had come as reinforcements, but Bulk pushed him out of the way and took the blow for the Rookie Hero. Bulk was subsequently trapped underneath the rubble until the villain had fled and the Heroes could dig him out with a Levitation Unit.

On a mission to Mekron City, Preston Stormer was attacked by Meltdown and was hit with the villain’s toxic sludge. Upon returning to the Hero Factory, Zib diagnosed that the sludge contained tiny nanobots that could hijack a robot’s systems. Shortly after this, Stormer went berserk and climbed up above Mission Control to the Training Spheres. Bulk, Stringer, and Furno followed him. In a confrontation atop the sphere, Stormer threw Bulk off the edge. Furno leapt down with a rope and grabbed hold of him, but the senior Hero was too heavy and slipped. Stringer, however, leapt to the rescue and pulled Bulk up to a ledge, letting Stormer get away.

Bulk then joined the mission to retrieve an antidote for the nanobots, while Furno headed out into Makuhero City to retrieve Stormer. Bulk and his companions traveled to Lunar Tratix, whereupon they were immediately attacked by a Tratix Reptoid. Bulk and Stringer kept the animal distracted whilst Natalie Breez found the necessary ingredient, only for the creature to focus on her, and nearly devour Surge. Luckily, Breez used her ability to communicate with nature to drive the beast away, and Bulk’s group returned to Hero Factory in triumph. The antidote was subsequently administered to Stormer, who was then cured.

The Alpha Team was later dispatched to New Stellac City to investigate a mysterious meteor strike. After they arrived at the site, Thunder and Corroder climbed out of the crater and did battle with them. Zib sent the rookies in as backup, although XPlode and Meltdown arrived at the same time as they. Von Nebula then appeared in the sky. He created a black hole with his Black Hole Orb Staff that sucked up the Heroes’ weapons, including Bulk’s Metal Sphere Shooter. Stormer and Furno leapt into the black hole to battle Von Nebula, leaving Bulk and the others to capture the villains. The Heroes used Particle Separators to dodge the villains’ attacks and stunned them. Bulk and Stringer wrapped a heavy metal bar around the villains, holding them captive. Shortly afterward, Stormer and Furno escaped the black hole, having defeated Von Nebula, and the team returned to Hero Factory in triumph.

Eventually, Bulk was given the Upgrade to 2.0 form once the process was considered perfected.

Savage Planet

Bulk, along with other members of the Alpha Team, received a distress call from Alodus Witch on the jungle planet of Quatros. A report from Rookie Hero Rocka, however, indicated that the planet had become unstable and that all wildlife would attack everything in sight. In an effort to adapt to the environment, the Alpha Team was given an upgrade to new animal armor, with Bulk gaining the attributes of a wolf.

Arriving on Quatros, the Heroes discovered that Professor Witch had been turned into a tyrant known as Witch Doctor after being exposed to the Quaza from a mysterious skull. Stormer then made a choice to split up the Alpha 1 Team into two groups. Bulk and Stormer would be led by Rocka and go through a teleporter to get to the Witch Doctor while Furno led Nex and Stringer into battle. Unfortunately the teleporter also shrunk the Heroes that they could not rescue the Heroes. However, Nex was able to get them back to their size once Furno’s team arrived. Bulk then helped remove the Quaza spikes of a Fangz and helped boosted Furno so that he could destroy Aldus Witch’s machine. He then returned to the Hero Factory.

Brain Attack

When Makuhero City was overrun by an army of Brain controlled creatures, Bulk received a metal shield and power drill as well as brain-protective armor. Bulk fought in the streets with his teammates Rocka, Stormer, Furno, and Breez. The Alpha 1 Team found it hard to defeat the brains until Bulk bashed a brain off a Bruizer. After that, the heroes began to win until a Dragon Bolt appeared and attacked the Heroes. When the Hero Factory was breached, Bulk helped his team fight blank robots until they were deactivated by Surge.

Invasion From Below

Bulk went to Antropolis City, along with other members of Alpha Team, when Antropolis was invaded by Jumpers. Bulk helped Rocka prep the Remote Builder so that the others could build their mechs, though Bulk didn't get to participate in the action himself until the heroes went into the tunnels under Antropolis to find Stormer and Furno, who had been captured by the Jumpers. There, Bulk took charge of the team, using his newly-built drill machine to blast through a wall that blocked the team's way (despite Breez's warnings that the wall was telling them not to do this exact thing).

Bulk helped the team get through the many challenges leading to the lair of the Queen Beast, where Stormer, Furno, and (now) Surge were captured. Bulk stood by as Breez negotiated with the Queen Beast for the Heroes' rescue and safe exit, which proceeded as planned until one of the Jumpers stepped on Bulk's dropped gun; Bulk, taking this to be a breach of terms as an attempt to start a firefight, began battling the Jumpers and the Queen Beast, bringing down the ceiling and, with it, all of the Jumpers, the Queen Beast, and himself. While the others managed to escape unscathed, Bulk was believed to have been destroyed, but luckily managed to survive and join the others. He then stood by as the citizens of Antropolis were informed that the tunnels had been sealed, guaranteeing them safety.

Abilities and Traits


Dunkan Bulk

Dunkan Bulk is regarded as one of the Hero Factory’s strongest active Heroes, a trait which makes up for his low intelligence. Bulk is always ready for a mission, and enjoys fighting for the Hero Factory about as much as he enjoys the actual fighting itself.

After the upgrade to 3.0 status, Bulk now has wolf-like powers, such as enhanced speed, to adapt better to the new jungle environment.


Dunkan Bulk initially had silver and black armor, while his eyes and Hero Core were colored translucent orange.

In Bulk’s 3.0 form, he retains his silver and black armor, as well as his orange eyes and Hero Core. His helmet now resembles that of a Wolf, as a symbol of his new abilities. In his breakout form gunmetal replaces a lot of the silver on his body. His secondary color of orange became more prominent after Nex stopped appearing with Alpha 1 team.


Bulk was originally armed with a Metal Sphere Shooter. He has also been known to use a jetpack on certain missions.

Bulk currently carries a pair of Wrist-Mounted Blades, which are able to slice through nearly any material.

During Breakout, he carried a Meteor Blaster, Hero Cuffs, and a large rocket.

Finally, during Brain attack,he carried a large shield and drill.

Set Information

Dunkan Bulk was released as one of the Hero Factory canister sets in July 2010. His product number was 7168, and the set contained 17 pieces.


Bulk And Vapor.

Additionally, Dunkan Bulk was released in a set entitled “Bulk and Vapor”, which included a villain known as Vapor. This set's product number was 7179 and contained 89 pieces, 21 of which were used in the construction of Bulk. The Dunkan Bulk featured in this set was nearly identical to the original Dunkan Bulk set, except for the addition of a jetpack, breathing tube, and Stringer’s Sonic Boom Weapon on his right arm. This is not Stringer’s weapon in the story, however.

Bulk’s latest form was released on July 2011 as one of the six canister sets in that wave. The set was sold under the name “Bulk 3.0” (in conjunction with the other “3.0” sets in the wave). His product number was 2182 and contained 30 pieces, including a translucent green armor piece printed with the name “Bulk 3.0” and a wolf pattern. His parts could be combined with Furno 3.0 to create a combiner model, and a code printed under his canister lid could be entered at as part of the HeroPad feature.

Bulk's Breakout set

The second part of Hero Factory’s Breakout line featured 6223 Bulk as a set. The set contained 61 pieces, and included is a Hero Core that contains a code for online content. The set included push-firing missiles, an operable plasma gun, and Hero Cuffs to use on the villains of the Breakout wave.

Bulk would be released yet again in the first part of Hero Factory’s Brain Attack line as set 44004 Bulk, containing 50 pieces including a Hero Core that contains a code for the Brain Attack online game. It featured a new helmet to connect to the head piece with a trans-orange visor to go with it.
