CT I just wanted to add something about Pterano vs. Icthy. He's also a VERY skilled hand-to-hand combatant (Revenge I).
-------------------
I call it a draw.
Petrie can attack in a 3d space and attack at odd angles. Also, he can drop objects on Ducky or even pick her up and drop her.
Ducky is probably stronger than Petrie and she could pull him down. In addition, Petrie's bones are probably less resistant to breakage due to them being hollow to allow flight.
So the conclusion is that, if Ducky does not manage ground Petrie quickly. Petrie wins. If Petrie is on the ground and trapped, Ducky wins.
