Lion
The lion possesses what zoologists at the Serengeti Research Institute describe as 'approximately 650 pounds per square inch of bite force, delivered through a magnificently engineered cranial structure.' Adult males weigh between 150-250 kilograms, with retractable claws measuring up to 38 millimetres. Their ambush hunting success rate of 25-30% may seem modest until one considers that each successful engagement typically results in complete dominance over prey items weighing several hundred kilograms.
However, the lion's combat repertoire is limited to what evolutionary biologists term 'conventional mammalian violence' - biting, clawing, and the occasional spectacular tackle. No elemental powers. No ranged attacks. Simply four million years of perfected lethality operating within the constraints of known physics.
Pikachu
Pikachu's combat capabilities exist in what the Tokyo Institute of Fictional Physics classifies as 'a complete departure from thermodynamic law.' The creature generates electrical discharges of approximately 100,000 volts from specialised cheek pouches - organs that would, in any conventional biological system, simply incinerate the host organism. The Thunderbolt attack alone releases energy equivalent to a small lightning strike, yet the creature weighs merely 6 kilograms and subsists primarily on apples.
Documentation from the Kanto Regional Pokédex indicates combat proficiency against creatures ranging from sentient boulders to literal gods. The lion, magnificent though it may be, has never successfully defeated a deity in documented combat.
