The Mutant Bear (named Homerton) appeared in the 2018 sci-fi horror movie Annihilation. It's presumably an American black bear that has been mutated from the "Shimmer" that the bear resides.
Description[]
The Mutant Bear seems to be an American black bear (Ursus americanus) although slightly larger than its nonmutated brethren. When Lena's team is ambushed by the bear the bear seems to retain its pre-mutated form save for patches of skin showing around its neck and head where its fur had withered away.
The bear reappears during Anya's interrogation of her teammates and torments the group. It's keen to note that it became more heavily mutated since they first made contact. Its body is largely unaffected/mutated to less of a degree, the skull of the bear is now visible, showing the lack of flesh on the bear's skull. Also, the bear's nose has also withered away, leaving the nasal cavity open, however, the bear has a human's skull embedded into its own. Human teeth are seen inside of the bear's mouth as a second row while still retaining its own set.
Behavior[]
The bear initially is shown to stalk the group while they rested at Fort Amaya. It tore open a hole in the fencing perimeter before swiftly grabbing Cass Shepherd, dragging her away from the group while she screamed for help. Interestingly while Lena found the grisly remains of Cass in the morning after, the bear didn't outright eat her, possibly leaving her body as a warning for the group.
While Anya began interrogating her teammates, the weak, croaked calls of "Help me" distracted Anya, as if Cass somehow miraculously survived such an attack. However, the bear was the source of the calls which he heralded with an ever so familiar bellow. While it circled around the bound trio, it seemed to constantly fill the air with bellows and the dying cries of Cass screaming "help me!" as to instigate a reaction from the trio. It went as far as to "Staredown" Ventress before clamping onto her shoulder as to break her, before it could further torment Ventress. Alerted by Anya firing away, it was quickly dealt with by ripping her jaw and throat apart, before it could give the same treatment to the survivors, Josie was swift to gun it down, ripping its skull apart with a hail of bullets.
