Some interesting details about MHF-Z's monsters and areas


 * Ray and Lolo Gougarf, as well as the Bamboo Forest, were originally planned for MHF-G4. The Gougarf were made to be MHF-G2's Flagship Monsters due to them being complete around that time, however, the Bamboo Forest was still in development. Originally, the Bamboo Forest would've been like wrestling ring for the Gougarf. The Gougarf would've been able to interact with the bamboo in the area in a variety ways while fighting, such as jumping off it, but that was ultimately dropped. The Frontier Team ended up changing a lot of the Gougarf's elements once they prepared for MHF-G2. Though the Gougarf weren't in the Bamboo Forest like originally planned, the team decided to make another monster, Inagami, based on the idea of interacting with the bamboo for MHF-G5.
 * Zenaserisu was originally going to be more bat-like in design. There is even some concept art of it hanging upside down like a real-life bat.
 * The Painted Waterfalls came from a scrapped area called the "Rainbow Falls" (Japanese 虹の滝). Like the name suggests, it was an area with many waterfalls and rainbows. The Rainbow Falls was going to be a special area where hunters could fight Plesioth. Plesioth would've been able to perform new attacks in the area by using the many waterfalls in the area.
 * Toridcless was supposed to be a Flying Wyvern, but the artist that drew it was bird watching at the time and based its design on birds of prey.
 * Kamu Orugaron was originally going to be the leader of smaller minion wolves. These minion wolves were Nono Orugaron.
 * The Sky Corridor was originally a maze with no monsters. Hunters would've worked together to solve puzzles in the massive maze to find various treasures, and other materials, in order to progress. This was scrapped because test players had trouble figuring out some of the puzzles they made up.
 * Guanzormu was going to be in the Fortress Ruins as a special monster for MHF-Z originally but was replaced by G White Fatalis. Interestingly, the Fortress Ruins and Cloud Viewing Fortress were once the same area.
 * In the concept phases Laviente was going to be a living area, in other words, a monster as big as one. However, the Frontier Team said it would've been too big and wouldn't even be considered a monster anymore.
 * Mi-Ru was going to have ten forms in the past, but the Frontier Team went with five instead (Not counting its normal form).
 * The Unknown (Black Flying Wyvern) was based on some artwork for Rathian, which comes from Hunter's Encyclopedia G. (https://www.instagram.com/p/BUfF_mKjvYX/?taken-by=monsterhuntergame).
