Penguin
The emperor penguin represents one of evolution's most remarkable achievements in biological resilience. These creatures routinely endure temperatures of minus sixty degrees Celsius whilst standing motionless for months, their bodies having developed specialised counter-current heat exchange systems in their flippers. Their feathers number approximately one hundred per square centimetre, creating an insulation system that would make any engineer weep with admiration. They survive four-month fasts during the breeding season, losing up to half their body weight whilst maintaining metabolic function.
Thor
As an Asgardian deity, Thor possesses durability that transcends mortal comprehension entirely. His physiology has withstood direct impacts from nuclear detonations, the crushing depths of dying stars, and the full fury of Thanos wielding multiple Infinity Stones. His flesh repairs itself with supernatural efficiency, and his lifespan extends across millennia without meaningful degradation. Thor has survived being hurled through the void of space, struck by weapons of cosmic power, and subjected to forces that would vaporise continents.
VERDICT
Whilst penguin durability is evolutionarily magnificent, Thor's capacity to survive stellar-level forces operates on an entirely different scale.
