SMG-IInd or Super Mechagodzilla the Second was created by the G-Force to destroy Godzilla, the thrusters on the back of his legs helps it him move out through the field, traveling at 330 kilometers per hour. It's automatic control, so it doesn't have a crew inside it.

You are the King of the Monsters, Godzilla, ready to cause destruction to Tokyo but that’s when all of the sudden, you hear a mechanical roar erupt through the air. You look behind you, and you see SMG-IInd. It stood 120 meters in height and had similar characteristics to Mecha-King Ghidorah and.. well.. Mechagodzilla.

You prepare yourself for battle, letting out a roar back.
