The second Transformers film, Revenge of the Fallen has been confirmed to feature the Constructicons and their combined form. The name "Devastator" was previously used in the first film incorrectly for the Decepticon Brawl, and Bonecrusher was also featured; both characters were killed and have been confirmed to not be returning for the sequel.

Demolishor appears in the teaser trailer. It is a Terex RH400 Hydraulic Mining Excavator, currently the largest excavator in the world. This robot will form the torso of Devastator; of which also a render appeared, that featured the name Devastator in the background. In the teaser, Demolishor is fighting against Optimus Prime, destroying a bridge.

The Constructicons confirmed for Revenge of the Fallen are:

Scavenger,[1] the Terex O&K RH 400 Hydraulic Mining Excavator seen in the first trailer.[2] He forms Devastator's torso.[3]
Long Haul,[4] a green Caterpillar 773B dump truck, which forms the right leg.[3] Long Haul's individual robot mode was designed by freelance artist Josh Nizzi as fan art of the original character Long Haul. The fan art impressed Bay enough to hire him on to the film.[5].
Rampage,[4] a Caterpillar D9 bulldozer who forms the left leg.[3]
Scrapper,[1] a Caterpillar 992G scoop loader who forms the right arm.[3].
Hightower,[4] transforms into a yellow Obelco CK2500 Truss Crane and forms the left arm.[3].
Mixmaster,[4] who transforms into a black and silver Mack concrete mixer. He forms the head.[3].
