The Constructicons are the Decepticons' foremost designers, engineers and builders. They are also particularly notable for their status as the very first combining subgroup of Transformers. The individual members of the team are:
- Scrapper, (usually) the leader, a modest but masterful designer - front-load loader.
- Bonecrusher, a destructive berserker - bulldozer (and later front-end loader).
- Scavenger, who has some major self-esteem issues - power shovel.
- Mixmaster, a manic and somewhat crazed chemist - cement mixer.
- Hook, a snobbishly perfectionist engineer - crane.
- Long Haul, a hard-working transporter who longs to be on the battlefield - dump truck (and later crane).
They are able to merge their bodies and minds together to form the gigantic Devastator. They are very extremely loyal to the Seekers.
