Rare Species
Rare Species are about as rare as Elder Dragons. Some Rare Species even have some abilities that is on par with Elder Dragons. It has even been found that some Rare Species use the Dragon Element like Elder Dragons, though isn't really noticeable most of the time.

Apex Monsters
Apex Monsters are said to be on par with a Frenzied Deviljho. They can destroy ecosystems, infect areas with the Frenzy Virus, and even destroy settlements. This puts them as Elder Dragon-Level Monsters.

Akantor
Akantor's overwhelming strength and the fact that it was temporarily classified as an Elder Dragon, makes it an Elder Dragon-Level Monster. It has been seen surviving in heavy thunderstorms and long droughts, before bring destruction to whole towns. When it appears, the public is evacuated from an area since it can bring on tremendous destruction like an Elder Dragon.

Rajang and Furious Rajang
In legend, Rajang was called an Elder Dragon. Despite being a Fanged Beast, it is stated that its power is equal to that of an Elder Dragon and that Furious Rajang are truly powerful enough to take on Elder Dragons. Rajang are also put into this group due to Kirin being a prey item for them.

Shen Gaoren
From Shen Gaoren constantly looking for and destroying things that disturb their territory, such as towns, cities, and barriers, it is considered an Elder Dragon-Level Monster.

Ukanlos
Ukanlos was classified as an Elder Dragon, temporarily, after it was discovered. It was feared that it would eventually team up with Akantor and bring destruction to numbers of areas with Akantor. It is considered to be equal to Akantor in power and about as aggressive. Even when just being discovered carelessly, or living close to a village, some Ukanlos will attack settlements immediately without warning. This puts them at a level equal to Elder Dragons.

Deviljho
A Deviljho's gluttonous behavior puts it on a level with Elder Dragons. It can make all nearby species in a area go extinct, including large predatory monsters. It has been seen killing and feeding on other large predatory monsters. Deviljho has also been seen attacking Rajang and Elder Dragons, not even leaving when these monsters appear.

Berukyurosu and Doragyurosu
Due to Berukyurosu's high intelligence and fighting abilities in the sky, it is considered to be an Elder Dragon-Level Monster. The same also applies for Doragyurosu.

Espinas, Espinas Subspecies, and Espinas Rare Species
An Espinas was able to fight and defeat an Elder Dragon. Though Espinas are generally calm, this still is enough to put it with Elder Dragons. The Espinas Subspecies and Espinas Rare Species are capable of this as well.

Odibatorasu
Like Akantor and Ukanlos, Odibatorasu is about equal to Elder Dragons. Unlike them though, it is known to prey upon not only monsters but also buildings and even rocks surrounding areas. Odibatorasu can even cause large sandstorms just with its breath. The destruction it can do, such as destroying settlements and ecosystems, is enough to compare to it an Elder Dragon.

Laveinte
Although Laveinte's classification is unknown, it is known that it can destroy a whole island from its gluttonous behavior alone. This compares it to some Elder Dragons.

Unknown (Black Flying Wyvern)
From the recent discovery of the Unknown(Black Flying Wyvern) in the Tower, it is said that it is perfectly capable of raining hell on villages and towns easily. This is enough to put it alongside Elder Dragons.
