Appa vs Zaheer

Appa wins pretty handily. Airbending doesn't have much in the way of offensive power, and we've seen most airbenders struggle to K.O. normal humans, Zaheer especially. Appa is much, much more durable than a normal human and will take considerable force to take down. Meanwhile Appa is a ten ton magical flying bison, and as such is fully capable of murdering Zaheer if a single physical attack lands. He also has a history of defeating bending masters in one air shot. He took down Azula, Ty Lee, and Mai all at once with one air blast. Destroyed Long Feng by tossing him like a skipping stone.

The only way Zaheer wins is with the shirshu darts.
