Elsa
Elsa possesses what thermodynamicists would classify as localised entropy manipulation - the ability to spontaneously generate ice crystals and reduce ambient temperature to lethal levels. During her coronation incident, she demonstrated sufficient power to plunge an entire kingdom into premature winter, affecting agricultural output and trade routes for an indeterminate period.
Her capabilities include the creation of sentient ice constructs, suggesting mastery over matter that transcends current scientific understanding. The energy required to instantaneously construct an ice palace has been calculated at approximately 450 megawatts - equivalent to a small nuclear reactor.
iPhone
The iPhone 15 Pro houses the A17 Pro chip, capable of performing 17 trillion operations per second. Whilst individually modest, the collective computational power of all active iPhones exceeds the combined processing capability of every computer that existed in 1995.
The device's true power lies not in processing but in behavioural influence. A single notification can interrupt surgery, derail negotiations, and terminate relationships. The iPhone's power to command human attention remains unmatched by any technology in human history, including television and the printing press.
