Not one of my favorites but my personal vote due to legacy is the bringer of the frenzy virus, and inflictor of the apex breeds_ Goa Magara/ Gore Magala
Why I think this? Majority of the flagship monsters have come into Monster Hunter World: Iceborne at this point, and this one so happens to be very popular among fans. MH4G is also heavily considered one of the best games of the MH franchise. So would make sense to finally add the dormant Elder Dragon into Iceborne
So, who does the Hunters in GD think it could be?
