A reliable source that has proved correct in the past has provided some information concerning the G1 combiner Devastator robot to TFW2005:

Devastator details

- Seven construction vehicles merge to form Devastator
- Devastator has lots of upper body strength, like a gorilla
- Not just green, some of the vehicles are red and yellow
- The previously Long Haul concept art by Josh Nizzi is legit

Quite frankly, something of this size and complexity would be both awesome and epic.

TLAMB raise some very valid points which put this news into doubt, and why I cannot report this as a confirmation. Specifically - we have not seen any construction vehicles during filming, a toy that is created from more than 5 parts presents a difficult engineering task for Hasbro - something that will be more expensive “than the $25 sweet point”. They also stipulate that given Prime’s height of 35 feet, the size of an average construction vehicle, this robot could reach up to 80 feet in height.

The Josh Nizzi Concept

Tim Flattery (IMDB), concept designer for the original Transformers movie adaptation, has updated his online portfolio to include some new Transformers concept art, most importantly including a first look at what might have been a huge, towering, transforming aircraft carrier - set to wreak havoc on all that stands in its path.

Check out Tim’s portfolio for more concepts that didn’t make it into the first movie.
