Note: fire-breathing steed of Lemuel Haskill (Bounty Hunter)
Lemuel Haskill (known as "Bounty Hunter") was a human spirit who resided in Hell and was a pawn of the devil Mephisto. Haskill's steed was a fire-breathing, flying black stallion known as "Hell horse." The Hell horse was presumably a creation of Mephisto (or a creation of Haskill, using Mephisto's power), or was in some other way a demon animal from Mephisto's hell. The Hell horse may have even been a "demonized" Earth horse. In any case, it is definitively a demon animal.
