Komodo Dragon vs Saltwater Crocodile
Quick answer
In a hypothetical one-on-one, the Saltwater Crocodile would most likely come out on top in most encounters, thanks to its more dangerous natural weapons and greater size and power. In reality, animals like these rarely meet, and both would usually avoid a fight.
This is a hypothetical, educational comparison based on typical size, strength, and natural weaponry. In the wild these animals rarely meet, and most encounters end without a fight.

Least ConcernEcology and habitat
Komodos are limited to Indonesian islands; salties overlap in Indonesia but dominate mangroves and coasts. Komodos hunt deer and water buffalo on land.
Adult saltwater crocodiles far outweigh Komodo dragons and are armoured with death-roll capability. Komodos are top island predators with venomous bites but cannot overpower a large croc in water.
