TRUCK MODE Really cool design for the price. If it wasn't for the plain gray plastic bits here and there, it would have been even better. The blue flames look really good on the red. Middle of the truck reveals a bit of the robot, but it's nothing too major. Tip of the hook/missile is visible at the rear. TRANSFORMATION Not a whole lot to do, but a lot of stuff going on. You start by lifting the top portion of the cab : feet (grill) automatically extend. Pull on the front portion (hood) to extend what will become the arms. Split that front portion in two to separate the arms. Now fold back that entire top section. As you push against the rear, the rear of the truck starts to move down (it's spring-loaded) to become the backpack. As you push further, the grey tab (visible in truck mode) starts pushing against the waist, making the arms fold down on each side through a gear system. Snap the backpack onto Prime's back, insert the missile in the launcher located on the left arm and you're ready for action! ROBOT MODE By far the best Fast Action Battler figure so far. Excellent poseability (knees, hips, waist, elbows, shoulders, head), very nice detailing on the head and the chest. You won't be disapointed with that one.
