This set is amazing! It has new parts like a blue roter helment and corroder wepeon armer. One thing I dont like is that dunkan bulk has a black stringer gun which really discolers it truley... Dunkan bulk also has a jetpack which is cool. This set has 89 parts which is a really low number for this large box you get. This is set is also 24.99 which is about just right for two figures. This set is awsome so go get it!!

I think this is a great set. A 2-for-1 deal with a hero and a villain.

Building
The building is good. It is easy to put together the set, and has many great parts.

Parts
The parts for this set are excellent. The hero, Dunkan Bulk, has a jet pack, a sonic weapon, and a metal sphere shooter. The villain, Vapour, has two vapour blasters and a huge sword blade. He has blue versions of corroder's claws down his shoulders, and a blue version of rotor's helmet. He also has really good armor pieces.

Play
This set is really good to play with. Both the hero and the villain have good flexibility and maneuverability. The only bad thing is that some of the pieces crack easily because the get too thin in places.

Overall
This is a really good set overall. Not only do you get a special Dunkan Bulk, you also get the limited edition Vapour. This set has really good parts, especially for MOCs. You should get this set.

I would recommend this set, escpecialy since it is a limited edition. Bulk is cool with the the guns and jet pack. Yah, he just looks awesome! Vapour is also awesome. His left gun with the scope is super cool but the right one dosen't always stay in place.

Not too bad, but pricey.

Pros

• Classic BIONICLE blue returns!
• Plenty of new parts.
• Vapour is quite cool.

Cons

• Expensive.
• Bulks arms have mismatched colours.
• Vapours helmet has no eyeholes!
• Vapours big claw arm is floppy.

Dunkan Bulk & Vapour is a pretty good set, but I have to admit, $25 for 89 pieces is a little bit too overpriced. I still think it's a great set, partially because it comes with two figures, an upgraded Dunkan (Duncan) Bulk, and Vapour, which only comes with this set.
