Magical Beast

Magical Beasts are a race of carnivorous creatures that lived in another world.

Appearance
The Magical Beasts are monstrous creatures with black-furred bodies. They possessed red eyes and massive sharp teeth.

The Earth variants have some resemblance to their relatives. Cid Kagenō described them as a cross between a lion and a bear.

History
The first incursion started when the Oriana Kingdom activated the "Black Rose" to use it against 100,000 soldier of the Velgalta Empire. Unfortunately, their world had collided with the Fourth Realm and the magical beasts entered through the Black Rose. The magical beasts proceeded to slaughter everyone that were in their way, until the Cult of Diablos stepped in and closed the Black Rose.

When the Black Rose was activated once more by the cult member, Mordred The 9th Seat Knight of Rounds, manipulated it to summon the Magical Beasts, along with Ragnarok. The Oriana Kingdom would had been annihilated, but the timely intervention of Shadow Garden changed that. Shadow Garden worked alongside the Oriana Kingdom to take out the Magical Beasts while Shadow confronted Ragnarok. The battle ended when Shadow destroyed both Ragnarok and the Black Rose.

Cid Kagenou and Beta would travel through a portal created by the Black Rose and arrived on Earth, Japan. To their surprise, they found the nation completely ravaged apart and populated by Magical Beasts.

Biology
Magical Beasts possessed magical power giving them strength and durability to take on most opponents. Their teeth allowed them to tear the flesh off their prey.

They are deadlier during the night as they are nocturnal in nature.

The beasts are able to curl themselves into black lumps, presumably for safer travel through the Black Rose.

The Earth variants are notably much weaker than their relatives that Shadow was able to kill off hundreds of them with ease. They lived in packs and build nests. Once the nest has reached a certain threshold, the beasts go on a rampage. This is presumably done to split the pack. The beasts would hunt food and gather them, building a new nest. This is called a Stampede. Apex Beast are a sub-species that are more powerful than the standard beast.

The only effective means to kill the creature is to use a sword imbued with magic. It takes at least 10 ordinary soldiers to even subdue it unless they have the Shadow Garden prowess.
