Hasbro Zoids Gustav is an action figure model kit that can be assembled without glue or paint. The kit includes a Phillips screwdriver (not included) to insert the battery, and requires 1 AA battery (1.5 V), which is also not included. The assembled figure can move its limbs and has a switch to turn it on and off. It is recommended to operate the figure on a smooth, flat surface for best results. If the limbs do not move freely, disassemble the model and trim excess plastic off of the building components using scissors or other suitable tools.
