User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-4361439-20130313230024

Watching the 2013 trailer for Monster Hunter 4, we can see what is most likely a Rathian infected with the Dragon Virus for a second near the end. Has anyone noticed this Dragon Virus infected Rathian looks almost exactly like the Rathian "Unknown" species? Black scales/skin, and bright red eyes. It's a stretch, but perhaps the Unknown Rathian in MHF is actually simply a Rathian infected with the Dragon Virus, which would explain why they're not a common sight compared to other types of Rathian. Also, depending on what exactly the Dragon Virus does to a Monster, it would explain why the Unknown Rathian is much stronger then the other subspecies.
