The newest Monster Hunter World: Iceborne trailer not only showcased the fan-favorite Tigrex, but also teased the return of a wyvern from a previous Monster Hunter generation: Glavenus.
At the end of the story trailer, which you can watch below, a hunter confronts a Rathian. Behind the hunter, you can just make out the feet of another monster in the back right corner. The screen cuts to black before we can get a clear shot, but the subsequent roar and fiery sword slice can only belong to Glavenus.
The brute wyvern was originally introduced in Monster Hunter Generations for the Nintendo 3DS. It’s huge, resembles a spikey T-Rex, and wields a heated blade-like tail. It sharpens its tail in its mouth, and one of its most powerful attacks is telegraphed by that very action. Fun fact, its tail can only be severed while it’s heated to the point of glowing. Otherwise, it’s hard as steel!
