Peregrine Falcon

Why?

A few reasons:

The Peregrine Falcon is the fastest animal on the planet in its hunting dive, the stoop, in which it soars to a great height, then dives steeply at speeds of over 200 mph (322 km/h) into either wing of its prey, so as not to harm itself on impact.

It's an endagered species currently in restoration. Screw with it and you are in BIG trouble.

It's a small beautiful mysterious bird that's extremely fast and VERY smart.
