Savage Deviljho can be found practically anywhere like normal Deviljho. Some of the areas Savage Deviljho have been reported inhabiting include the Deserted Island, Flooded Forest, Tundra, Sandy Plains, Volcano (3rd), Misty Peaks, Ancestral Steppe, Sunken Hollow, Volcanic Hollow, Frozen Seaway, Heaven's Mount, and Primal Forest.
The Savage Deviljho easily assert themselves as Super predators that rival Elder Dragons in any conceivable habitat they find themselves in and are challenged by little. The only things that challenge them are other Deviljho, some other powerful monsters on par with Elder Dragons such as Rajang, and Elder Dragons. The long-ago healed gashes visible in their sides suggest that they constantly engage in titanic battles against creatures both as vicious, powerful, and sizable as themselves. Unlike normal Deviljho, Savage Deviljho won't hesitate to attack anything without a second thought. This means that Savage Deviljho are more willing to attack different species in ecosystems such as Rathalos, Uragaan, Zinogre, and Zamtrios in order to feed themselves. In most cases, Savage Deviljho are quite successful in doing this, even killing other Deviljho to feed themselves.
The Savage Deviljho has many of the same adaptions as a normal Deviljho, however, has a few minor differences. Savage Deviljho are noticeably always enraged. This due to the Savage Deviljho being extremely hungry and constantly needing to feed. By constantly being enraged, it makes Savage Deviljho weak to attacks. To make up for being constantly enraged, Savage Deviljho have a state beyond a normal Deviljho's enraged state. This state covers the Deviljho's face in a mask of the Dragon Element, giving it a more sinister look. This state comes from the dragon energy of other Deviljho it has cannibalized. This state increases its defense on certain parts of its body and gives its Dragon Breath more range. However, while in this state the very dragon surrounding its face is actually slowly killing it. The longer a Savage Deviljho is in this state, the shorter the Savage Deviljho's life span. The hide and the blood of Savage Deviljho is black in color due to the effects of the Dragon Element.
In Mezeporta, the Hunter's Guild have created a Savage Deviljho that are far more dangerous than any wild specimens. These Starving Deviljho noticeably have a golden hide and aura, spikes on back and tail and sharper teeth. These Deviljho even have better control over the Dragon Element compared to wild Deviljho.
The Savage Deviljho is an even more brutal and rabid monster than the ordinary variety due to its unrelenting hunger. The black blood may drive the Savage Deviljho to such heightened aggression, even causing it to become a 'rogue' killing machine.
