Time
Time presents what physicists describe as absolute persistence—a quality that renders all resistance not merely futile but conceptually meaningless. Since the Big Bang approximately 13.8 billion years ago, time has maintained an unbroken forward momentum, pausing for nothing and no one. It has witnessed the birth and death of stars, the rise and collapse of mountain ranges, and the entire evolutionary history of life on Earth. Entropy, time's faithful companion, ensures that all ordered systems eventually succumb to disorder. Most remarkably, time achieves this universal dominance without expending any apparent effort whatsoever—it simply continues, with the serene indifference of a force that knows it will ultimately outlast everything.
Wolverine
The wolverine's persistence operates on an entirely different but equally impressive scale. Documented cases reveal individuals travelling over 900 kilometres in search of territory or mates, traversing mountain ranges that would challenge Olympic athletes. When pursuing prey, wolverines have been observed tracking caribou through deep snow for days, their low-slung bodies and oversized paws functioning as biological snowshoes. Perhaps most tellingly, wolverines regularly steal kills from wolves and bears—animals that outweigh them by factors of ten or more—through sheer bloody-minded determination. They simply refuse to accept that they should be intimidated, a strategy that proves surprisingly effective against opponents who expect smaller creatures to behave sensibly.
