Its name is Unknown. It is fandubbed as Unknown Rathian because of its resemblance to Rathian but it is NOT its official name because it ISN'T a Rathian Species. Therefore it can be a male or a female because it isn't a species of Rathian.

And it ISN'T a counterpart of Zerureusu as Zerureusu is NOT an Unknown Species.

I don't play the game but I am aware of what facts are.
