What was the most terrifying animal you encountered?

A few weeks ago, a few workers in nearby plantation complained of wild fowls squealing and clamouring. Next time it happened, a couple of us went to investigate. It was like a battlefield. The wild flows were flying around, producing loud noises in a certain area. As we approached, we noticed a big king cobra standing up almost to a man's height. It was hissing and posturing. The ladies who came with us shrieked in fear and ran.
They refused to work near that location for a month.

It was a scary sight, but I must say that it was also magnificent. It is a majestic animal.
