What is the strongest fierciest and scariest animal in whole world?

There's no single "strongest, fiercest, and scariest" animal in the world! It depends on what you mean by those terms and how you measure them. Here's why:

* Strength can mean physical power, bite force, or even sheer size. A blue whale is the largest animal, but it's a filter feeder, not a predator. A hippopotamus has incredible bite force, but it's mostly herbivorous.

* Fierceness often refers to aggression or willingness to fight. Lions are known for their ferocious hunts, but a mother bear protecting her cubs can be incredibly fierce.

* Scary is subjective. What one person finds terrifying, another might find fascinating. A spider might be terrifying to someone with arachnophobia, but a crocodile might be more fearsome to others.

Instead of trying to find the "one" scariest animal, it's more interesting to consider:

* The animal's natural role: Some animals are designed to be predators, while others are prey. Each has adapted to survive in their environment.

* How the animal uses its strength: A cheetah's speed is its weapon, while an octopus's camouflage and intelligence make it a formidable hunter.

* Your own perspective: What makes an animal "scary" to you? Size, appearance, behavior, or something else entirely?

Ultimately, the "strongest, fiercest, and scariest" animal is a matter of opinion and depends on how you define those terms.
