Instructions
Push the wings toward each other while the Unicron Transformer is standing upright. Pushing the wings together will remove them from their brackets and allow you to take them off completely. Set the wings to the side. Press the horns on top of the head down into Unicron's head and then press the head backward.
Close the hands and turn them both 180 degrees so that they are facing the opposite direction. This will pop up a small door on the inside of the arms. Push the hands into the opening and close these doors to secure the hands inside. Push the arms up so that they are straight out in front of the figure.
Rotate the arms down so that the upper portion of the arms swings down and attaches to the legs. When the upper portion of the arms are attached, rotate the main arms 90 degrees upward. Push downward on the lower-middle body piece to open up the middle of the robot and pull it down. Push the two arms together so they meet in the middle of the robot's chest.
Rotate the sides of the legs of the robot 180 degrees so that they are facing the opposite direction. Grab the feet and push them back around the leg so that they fit inside of the opening on the backside. You can now rotate the legs so that they connect to the front of the robot, forming a large ball.
Grasp the top portion of the arms that are sticking out from the ball and pull them up to form a circle around the center piece. Attach the ends of these arms together to form the ring around the center of the planet. Finally, pick up the wings and attach them to the open side of the middle portion, creating the center of the planet.
