V'ger is massively powerful, stated to have more energy output than thousands of Starships, is capable of turning beings and objects into storable data and can scan living being to create close replicas.
So hard to say, it would definitely take the heavy hitters who can fly in space to get through and survive the ultra-massive cloud that surrounds V'ger to have a shot; that is if they can get through its shielding first.
Possibly Silver Surfer, maybe Thor. Wouldn't be surprised if Strange has a shot after his film comes out. Thanos with the gems another one.
