Overall Winner
- Crocodile: Wins in categories like bite force, senses, and agility in water.
- Hippopotamus: Wins in categories like social behavior, endurance, and size.
- Final Verdict: The hippopotamus has the edge in a one-on-one encounter due to its massive size, strength, and aggression, but the crocodile dominates in aquatic ambush and bite force.
