Things You May Not Know About Seregios(Info from MH4G and MH4G Official Site)
 * Firstly, the Guild has known about Seregios' existence for a long time and according to them, Seregios doesn't live in the Dede Desert(Old Desert/Dunes)or any of the other environments they've been seen in. They come from a different land and in a sense can be considered an invasive species from a different land, much like Baruragaru.
 * The Guild did let hunters hunt Seregios but they were very limited due to how rare this monster was until they recently became a problem in the Old World. As of now most didn't even know about this monster, including many hunters.
 * Seregios are very violent fighters and are highly territorial monsters. Seregios are even known in their own land to battle each other for better territories and in most cases, one of them will end up dead while some will live on. Seregios very rarely leave far from their territory.
 * If Seregios lose their territory, they will search for a new one or in some cases will steal one from another large predatory monster, including their own kind(That's why it was seen attacking the Rathian and Azure Rathalos).
 * Seregios greatly resembles some Ancient Wyverns.
 * The foot claws of Seregios can hold on to prey and the grip of its feet, make it extremely hard for prey to break free. If faced with many foes, Seregios will actually use their captured prey in their feet as a weapon.
 * Some large Seregios have even been seen holding Flying Wyverns smaller than themselves in their claws such as other smaller Seregios.
 * Seregios' flying mobility and flight control is actually comparable to Rathalos'.
 * Their whole body is covered in Blade Scales which are extremely sharp yet thin. These scales can cut through the tough armor of prey and can fling at prey from a distance. On impact, these scales can leave a complicated gouges in prey along with rocks. The wounds these scales leave behind are very painful and the pain from that injury can stay with prey for a long time.
 * The reason why the Seregios have recently appeared in so many areas is because of the Extreme Seregios that kicked them out of their land. The Extreme Seregios had been infected by the virus but was able to overcome it and became a major danger that should be feared from it now spreading the Frenzy Virus around, much like Shagaru Magara, along with greatly increasing its strength by using the virus itself(Most monsters infected die from the virus shortly after being infected while the Extreme Monsters were able to overcome the effects of the virus yet, similar to the Magalas, can spread the virus without being effected by it and now use the virus to increase their own strength). It was even said to be a lot more dangerous than an Infected Deviljho. From it being in its Extreme State it also, like many other Extreme Monsters, uses this new found strength to eliminate rivals of their own species more easily.
 * Its horn is described to be a very thick, sturdy blade.
 * The claws on its wings are used to help it control itself while in the air and allow it to shift its weight more easily.
 * Its tail is described as a spear able to pierce prey and is covered in many Blade Scales.
