Disclaimer: This is merely a plausible explanation for the monster(s) in this article, and should not be considered canon.
Taxonomy
The Rukodiora share the general build of other Elder Dragons. has large gold colored horns, golden wings, grey scales, and spines along its tail. Its wings are most unusual. It is not the traditional Dragon's wings, but it resembles more to "fins."
Habitat Range
Rukodiora has only been spotted in the Interceptor's base. It is still unknown though if this is its real habitat or not.
Ecological Niche
Rukodiora has not yet been seen interacting with other monsters. So explaining its ecological niche will have to wait until further notice.
Biological Adaptations
Rukodiora has large gold colored horns, golden wings, grey scales, and spines along its tail. It seems to be able to control magnetism. The best possible explanation for this kind of power is:
Rukodiora's ancestors posses the ability to tell where to go when migrating to different areas like our present day birds. These birds have a natural "compass" which helps them to know where they re going. This ability has developed through a long period of time for Rukodiora, long enough to be able to actually control magnetism.
Behavior
Rukodiora are aggresive creatures. It currently lays siege to the Interceptor's base. In theory, the sight of this area near its nest/habitat has made it feel unsafe, thus laying siege to it. Due to this, it is safe to say Rukodiora are very territorial.
Though not seen interacting with other monsters, including its own kind, it is very aggresive at hunters. Using its arms, tail and its magnetism powers to attack them.
