King Cobra vs Komodo Dragon
Quick answer
In a hypothetical one-on-one, the Komodo Dragon would most likely come out on top in most encounters, thanks to its greater size and power and raw strength. 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.
Reptile
Vulnerable
Reptile
EndangeredEcology and habitat
King cobras range across South and Southeast Asian forests; Komodo dragons are island endemics in Indonesia. They never meet naturally.
King cobras deliver neurotoxic venom and specialise in eating other snakes; Komodo dragons have slashing teeth, venomous secretions, and 70 kg of reptile muscle. On land the dragon's mass and armoured hide usually prevail; the cobra wins only if it lands a clean bite first.
