Luckily, Kong overcomes the mind control and runs to Japan. Doctor No and Mechani-Kong follow, when in Tokyo, Mechani-Kong climbs tokyo tower. Kong follows and a battle ensures. After battling it out, Kong finally manages to knock Mechani-Kong to the ground, where he shatters into hundreds of pieces.
