Cat
The domestic cat possesses retractable claws, exceptional night vision, and reflexes capable of landing on their feet from nearly any fall. In their natural scale of combat, cats demonstrate lethal efficiency, with some studies suggesting they are responsible for the extinction of 63 species worldwide. This predatory effectiveness cannot be dismissed.
However, cats weigh approximately 4-5 kilograms on average. Their combat capabilities, whilst impressive against songbirds and mice, face obvious scaling limitations when confronted with beings possessing superhuman strength. A cat cannot deflect bullets with its paws, regardless of how quickly those paws might swipe at dangling strings. This represents a categorical disadvantage in traditional combat metrics.
