Monday
Monday possesses what scholars term absolute temporal permanence. Unlike physical entities subject to entropy, Monday exists as a mathematical certainty within the Gregorian calendar system. It cannot be destroyed, delayed, or diminished by any known force in the universe.
Archaeological evidence suggests that the concept of the first weekday has survived the collapse of every major civilisation in recorded history. The Roman Empire fell; Monday persisted. The Byzantine Empire crumbled; Monday remained. This entity demonstrates a durability that transcends mere physical resilience—it exists in the realm of pure inevitability.
Wonder Woman
Diana Prince demonstrates exceptional physical durability, having withstood combat with beings of godlike power across eight decades of continuous publication. Her Amazonian physiology grants resistance to conventional weaponry, and her divine heritage provides protection against mystical assault.
However, Wonder Woman's existence remains contingent upon cultural relevance and corporate intellectual property decisions. Characters have been retired, rebooted, and reimagined throughout comic book history. While her current standing appears secure, she lacks the ontological permanence that Monday enjoys as a fundamental unit of temporal measurement.
