Must be a defining trait - Characters with access to vast powers (i.e. magical spells, advanced technology, genetic engineering, etc.) who are theoretically capable of this superhuman feature or ability - but whom have neither made regular use, nor provided a notable example, of this extraordinary or supernatural feat - are not listed here.

Must be an innate trait - This category does not include characters who use temporary enchantments, powered exoskeletons, or other "external aids" (such as Master Chief and Doctor Doom). This also does not include characters whose universes are absent of logic or causality and carry an ignorance to the laws of physics, such as Bugs Bunny and Donald Duck.

Must be a superhuman trait - This category does not include characters who can lift less the 2,000 lb (910 kg) [1 ton]; if the character is non-human, the character must exceed the limitations of their species. For perspective, the average physically fit human is able to "lift/drag/carry" one's own body weight; up to double one's own body weight. Olympic weightlifters are near the limit of human potential, being nearly five or six times stronger than the average human, who will struggle to lift 100 lb (45 kg) over their head. The official heaviest deadlift record lifted 458 lb (208 kg) kilograms; with an overhead lift stands at 581 lb (264 kg) kilograms (see Andy Bolton); the Guinness record for greatest weight ever lifted by a human being at 6,270 lb (2,840 kg) (see Paul Anderson (weightlifter)).
