@ROMM I sincerely doubt Gobul is going to appear in Iceborne because I think they waiting to bring him back officially whenever they bring back underwater combat. To elaborate, I know Yuya Tokuda (MHW's director) said that he would love to bring back underwater combat in a future installment, but he doesn't know when that will happen exactly. However, I think it is VERY LIKELY that Nibelsnarf will appear in Iceborne since he is one of the top go-to desert monsters in the series. We know this is likely because they showed Nargacuga appearing in Ancient Forest which heavily implies that Capcom will be probably be adding other returning monsters to vanilla areas and I think Nibelsnarf would be one of the top candidates for Wildspire Waste.

IF this guys appear, hope to see Nimbelsnarf

i hope they add this guy to MHW because it's really epic. (and i wanna fight it duh)
