Fatalis's Concept


 * While Rathalos was based on a Wyverns (Japanese ワイバーン), Fatalis was based on Dragons (Japanese ドラゴン). Fatalis originated as different level of fantasy, compared to other monsters in the first Monster Hunter.
 * Fatalis was meant to be a fantasy-like monster to add more variety to the world of Monster Hunter, along with showing that not all monsters were like our real world creatures. They wanted Fatalis to be this monster that was only considered a rumor so it could be a surprise for hunters at the end for online.
 * This is also what they tried to achieve with Alatreon.
 * They also wanted Fatalis's existence to be something that players would spread around and argue whether it was real or not.
