7179 Dunkan Bulk and Vapour is a 89 piece Hero Factory special edition set released in July 2010. The set contains two figures, Dunkan Bulk and Vapour. In the set Dunkan Bulk uses a Sonic Boom Weapon and a Metal Sphere Shooter.
In this set, Dunkan Bulk has slight modifications, like an Av-Matoran jetpack and a new right arm, which is also used as the arm of 7170 Jimi Stringer, and an orange pipe on his head. Vapour's shoulder defense are made of the same part as Corroder's claws. His mask is identical to that of 7162 Rotor, apart from colour. Also, Vapour's weapons are Meteor Blasters with opaque spheres. Vapour's head is the same shape as the Heroes and the colour is blue.
Vapour was able to shoot corrosive vapor using his weapons which are connected to two tubes.
- This set is the only villain set with blue opaque projectiles for the Meteor Blasters.
- Originally, LEGO spelled the set 'Duncan Bulk und Vapour' by mistake.
- In Germany, the United Kingdom, and the United States, it was a Toys "Я" Us exclusive.
- It is believed that the set originally was going to be "Thresher and Vapour," because Dunkan Bulk closely resembles Thresher, Stormer's first team leader.
- Besides Bulk's Regular blaster, he also holds Stringer's sonic boom blaster.
- Vapour is the ony villain that has two blasters instead of one.
