Do you have any ideas for a dragon rider version of the term "Jedi hunter"?

I'm writing a How to Train Your Dragon fanfic based on the Star Wars Expanded Universe, if you're wondering.

Now, for context, if you couldn't tell: A Jedi hunter is someone who is adept at killing Jedi.

This term is supposed to be for a person who is adept at killing a dragon's rider.

Not their dragons. Their riders. Dragons are more valuable alive.

Originally, I had a name for it, which was "Dragon Stalker", but I don't like it anymore and I want a new one. Something that carries the same threatening weight as Jedi hunter does.

And before you ask... NO: Dragon Slayers, in my fanfic, are based on the vampire hunters from the Legacy of Kain series, which I grew up with on the PlayStation 2.

Thanks for understanding.
