Thor is an Asgardian god whose power completely eclipses Vader's Force abilities.
Thor has fought the Hulk, survived attacks from Galactus's heralds, and commands divine lightning that can shatter planets. Darth Vader, while terrifying within Star Wars, operates at a fundamentally lower power tier. The crossover power scaling makes this a severe mismatch.
Vader's Force choke would need to overcome Asgardian physiology that has survived the vacuum of space, star-level heat, and physical trauma that would destroy continents. Thor's divine nature likely provides significant resistance to telekinetic manipulation. A lightsaber strike, even if it connects, faces skin that withstands nuclear-level impacts.
Thor's lightning alone would be instantly lethal to Vader. A single swing of Mjolnir generates more force than anything in the Star Wars universe. Thor could end this fight in a fraction of a second without effort.
Vader's Force precognition and telekinesis allow ranged attacks and tactical awareness. The dark side grants unique abilities that divine beings may not be prepared for, and the Force choke bypasses physical defenses.
Thor's divine lightning, Mjolnir, and godlike strength operate at a tier far beyond Star Wars. His Asgardian physiology resists telekinetic manipulation, and a single attack would be instantly fatal to Vader.
Thor wins effortlessly. The power gap between an Asgardian god and a Star Wars Force user is immense. Vader's Force abilities cannot threaten someone who trades blows with the Hulk.
