Varanus tristis.. outrun a snake with an IQ & legs.

I bet he eats whatever he wants.
The bio mechanics of Varanidae is optimized for maximum forward thrust, climbing & swimming, one of natures most perfect machines. They have distinctive hands and feet with the Prehensility of a primate, almost an equivalent cognitive function (they think and problem solve) and come with a built in turbo charger for oxygen delivery providing endurance. That should qualify for world's coolest.
