Sea Lion vs Orca
Quick answer
In a hypothetical one-on-one, the Orca would most likely come out on top decisively, 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.
