^ MH Flash's theory about Kirin is that it's so rare because it's so powerful that it doesn't even have to reproduce to keep its species living. So I can easily see Kirin take down some regular wyverns. Oroshi is probably powerful enough to freeze solid a Rathalos in the air.

You don't mess with elder Ds, no matter their size.
