Slow here but i got this as a present for my 30th birthday.

Optimus Prime toy from the Revenge of the Fallen movie.

Once out of the box, it took me quite some time (~2 hrs) to get it transformed to the truck.

The waist area extended…

Lower torso laid flat…

Front grill of truck can be seen from under boot feet…

Undercarriage of the truck formed…

Upper torso in position…

Chest opens up…

Head disappears…

Last stage of transformation…

Transformed!!!!
