Rubber Duck
The Rubber Duck represents a masterclass in material resilience. Crafted from vulcanised rubber or modern PVC compounds, this specimen can withstand temperature fluctuations from near-freezing bath water to the scalding preferences of the particularly hardy bather. Its structural integrity remains uncompromised whether squeezed by the iron grip of an enthusiastic toddler or gnawed upon by the family dog. Perhaps most remarkably, the Rubber Duck exhibits an almost supernatural resistance to existential wear—its cheerful expression remains unchanged whether floating in champagne bubbles or forgotten in a murky garden pond. Museum specimens from the 1940s maintain their form to this day, a testament to engineering excellence in the service of bathtime companionship.
Thor
Thor's durability stems from his Asgardian physiology, a biological marvel that renders him virtually impervious to conventional harm. He has survived being struck by spacecraft, plummeting through planetary atmospheres, and enduring the full force of a dying star. His cellular regeneration defies mortal understanding, allowing him to recover from wounds that would obliterate lesser beings. However, one must note certain vulnerabilities: Thor can be rendered unconscious, has been successfully restrained by various magical means, and demonstrates documented susceptibility to family drama. His emotional durability, whilst improving over the centuries, has proven more variable than his physical constitution, particularly when faced with sibling treachery or paternal disappointment.
