Suggested by Destroyer Hammer Head is reasonably strong but he has no main long range abilities which is what hurts him here. In a battle against a Kaiju, having speed and long range options is always your best bet at victory. Without either of those attributes then simple strength is not going to cut it. I don’t see Hammer Head being able to do a whole lot here and while he is durable, he would eventually go down to those energy blasts. King Ghidorah wins.
