Godzilla's massive size, nuclear-powered attacks, and extreme durability make Vader's Force powers insufficient.
Godzilla stands hundreds of feet tall, weighs tens of thousands of tons, and can unleash atomic breath hot enough to melt entire city blocks. Vader's Force powers, while impressive against human-sized opponents, face serious scaling problems against a kaiju of this magnitude.
Vader's Force choke targets the throat, but Godzilla's neck is enormous and his physiology can withstand nuclear detonations. The amount of telekinetic force needed to affect Godzilla's airway likely exceeds anything Vader has demonstrated. His lightsaber, while it cuts most materials, would be like attacking a mountain with a kitchen knife.
Godzilla's atomic breath alone would vaporize Vader and everything around him. His tail, claws, and massive body present physical threats that Vader cannot counter. The kaiju has survived meteorite impacts, nuclear weapons, and attacks from other kaiju โ Vader's Force abilities are trivial by comparison.
Vader's Force telekinesis could potentially affect Godzilla's movements or attack vulnerable areas like eyes. His precognition lets him dodge attacks, and the Force has demonstrated power that does not always scale with physical size.
Godzilla has survived nuclear weapons and meteorite impacts. His atomic breath would vaporize Vader instantly, and his sheer mass makes Force telekinesis impractical. He is simply too large and too durable for Star Wars-level powers.
Godzilla wins through sheer scale. Vader's Force powers were never designed to affect creatures of this size and durability, and Godzilla's offensive capabilities are instantly lethal to a human-sized target.
