Delma-Ioprey is a large Bird Wyvern that has only been featured in the MH Orage manga. Its body resembles that of a falcon or eagle. It forms a petrifying saliva that it can throw at enemies and has a breath that crystallizes its enemies into glass or dulls your weapons immediately. .
- It has thin and fleshy skin on the throat area, making it its most weak spot. Huge damage is done to this area with Pierce bullets from a Bowgun .
- The materials of the Delma-Ioprey are dark and glittery .
- Despite its name, it has no known relation to a monster of a similar name, Ioprey, apart from both being in the same Bird Wyvern monster type.
- It's name is most likely a result of an interesting/ 'mis'-translation. The japanese name of Ioprey and Delma-Ioprey are respectivery 'Iosu' and 'Derumaiosu'. The translators might have taken this sort of approach to the name.
