For some people wondering about MH4G's G Crimson Fatalis, it turns out it does have a story to it.

Some years ago, some hunters went to the Castle Schrade and defeated a Black Fatalis that fled from the Castle Schrade. It was unknown what happened to that Black Fatalis until it was found again some years later but now at the Lava Island, where it had dramatically changed(The Great Elder constantly calls it a Black Fatalis). It seems after that battle, the Fatalis Brethren became known around the Guild and by more hunters than ever before.
