LEGO 7168 Duncan Bulk

7168 Dunkan Bulk is a Hero Factory set released in 2010 that includes a small silver Hero in 1.0 form.

A silver-armored hero, Bulk has an orange head and core, black limbs, and a massive blaster arm weapon. The blaster connects to his body through a Toa handpiece and displays a long silver barrel, a harpoon on top, three non-removable orbs, and thick armor where his arm would go. The 'hand' molded into his armor has the trigger finger sticking out of the gun more than the other two. On the back of the bus you can see him fighting XPlode.

The toughest, strongest hero of the Hero Factory Alpha Team, Dunkan has built-in heavy multi-function metal weapons that shoot metal spheres and help protect everyone from danger. He is not very smart, but makes up for this with his strength and bravery in battle. He also fought alongside Mark Surge and Jimi Stringer to defeat Corroder

His Hero Core is green in some photos and blue in one photo. However, in reality it is orange.
Dunkan is also included in the 7179 Dunkan Bulk and Vapor set.
The spelling of his first name tends to differ. In one place it is spelled with a "k", like Dunkan, and in another place with a "c", like Duncan.
The barrel of Bulk's gun is angled so that it has a 3D effect in a diagonal view.
He is similar to a former Hero Factory team leader, Thresher.
Although it was re-released in 2011 as Bulk 3.0, it was not released in a 2.0 form.
His weapon arm is a single, hollow piece.
