No single lion can threaten a 14,000-pound elephant — this is a complete mismatch.
In the wild, lion prides occasionally take down elephants — but it requires an entire pride working together, typically targeting young, old, or sick individuals, usually at night. A single lion against a healthy adult elephant? Never.
The elephant outweighs the lion roughly 28:1. Its hide is too thick for the lion's claws. Its tusks and trunk are lethal weapons the lion has no defense against. A single kick or stomp could kill the lion instantly.
This isn't disrespect to the lion — it's simply the reality of extreme size differences. The lion is the apex predator of the savanna against prey its own size. An adult elephant is not prey.
28:1 weight advantage. Impenetrable hide. 6-foot tusks. The lion literally cannot hurt the elephant enough to matter before the elephant retaliates with lethal force.
The lion is faster, more agile, and has sharp claws and teeth. It could target the elephant's trunk, eyes, or hind legs. But none of these attacks would be lethal against something that weighs as much as a house.
The elephant wins overwhelmingly. No single predator on Earth can take down a healthy adult African elephant. This is nature's undisputed heavyweight champion.
