Fogbeast

The Fogbeasts are enemies in Xenoblade Chronicles: Future Connected, and Future Redeemed.

Appearance and properties
In Future Connected, Fogbeasts are the Bionis's wildlife overtaken by black shadows, and becomes more aggressive, even docile species, such as Armus can turn aggressive. The Fogbeasts are connected to the rift above and the Fog King.

Fogbeasts in Future Redeemed are drastically different. They now take the appearance of a phantom version of Aionios's wildlife, similar to the Fog King. There are also Fog Rifts that spawns Fog-called Beasts. These Fogbeasts are connected to Alpha.

Future Redeemed
Fogbeasts are first seen alongside an Alpha-possessed Na'el, killing City refugees as they are running from Kevesi troops. In a flashback, Matthew, and Na'el dispatched a few Diastone Ferises at Erythia Sea, Matthew remarks that they give off the same energy as Moebius, but at the same time it is not. After the encounter with Alpha at, Fogbeasts and Fog Rifts begin to show up around the Cent-Omina region, occasionally replacing the natural wildlife. With's Alpha's death, Fogbeasts cease to exist.

Future Connected
Fogbeasts are regular enemies that can be identified by the black shadows surrounding them. Fogbeasts are much stronger than their regular counterparts. Sometimes Fogbeasts can increase their levels during battle.

Future Redeemed
Fogbeasts return in Future Redeemed, now taking the shape of a phantom version of Aionios's wildlife, sometimes replacing said wildlife. There are also Fog Rifts scattered all over the Cent-Omnia Region. Battling them spawn a fixed number of Fog-called Beasts. Destroying Fog Rifts yields s.
