One of my disappointments with the way Oda handles Zoan users is that he does not or exploits little the fact that they should have enhanced senses. The fact that P1 wasn't show to be able of smelling or hearing Sanji while he was wearing the RS was a let down for me.
Unfortunate, but true. One of the main reasons Zoan DFs fall so far behind is because Oda doesn't emphasize unique animal attributes and just makes them behave like roided up musclemen with claws, teeth and a tail or wings. Kaku is one of my favorite Zoan users because of all the tricks he pulled out from his awkward long giraffe make up, his signature move using his long strong neck to project a powerful slice that cut the tower, he's definetely CP0 material doing all that with a brand new DF.
In general, animals:
- Have very sharp eyes that can see very far away, a larger field of vision around you, track rapid movement easier, some are even nocturnal for night-vision.
- Can pick up and track feint scents, distingushing between the many available. You may not recognize your best friend by smell but animals do that for all the people they meet.
- Sensitive hearing, to the point that they might as well be hearing the vibrations in the earth itself.
- Superior sense of balance. If knocked off their balance, they recover more easily. They know what jumps they can make, what cliffs they can climb to a far better degree. Doing consecutive backflips would be a cakewalk.
- Electromagnetic reception. Their senses are more attuned to the magnetic field to allow them to follow migratory patterns, find their way home, predict earthquakes and landslides, etc. This would be your "spider sense".
Now imagine if all these things were turned up by an order of magnitude like Zoan animal strength and toughness seem to be. It should logically be a bunch of Spidermans running around. Double or triple those capabilities for Ancient and Mythical Zoans.
