The Makkapitew

The Makkapitew was a main antagonist of the Prologue of Until Dawn: Oblivion. He was the first and strongest of all the Wendigo species, and was arguably the most lethal as a result.

The Makkapitew was killed by Hulk after it tried to eat Beth in front of her sister Hannah, despite Hannah pleading it to leave them alone.

Backstory
Like all Wendigos, the Makkapitew was a human who resorted to cannibalism while atop Blackwood Pines, causing him to transform into a Wendigo. The Stranger's grandfather dedicated his entire life to hunting Wendigos. Despite his prowess as a monster hunter, he could not defeat the Makkapitew, who in turn killed him instead by trapping him in the mines, where the man slowly starved to death while the Makkapitew escaped into the cold night.

One Year Ago
The Makkapitew is out hunting on the same night of Hannah's prank. It knocked out The Stranger and picked up Hannah and Beth's scent. After she and Beth fled the lodge after Jessica and Mike's prank on Hannah, the Makkapitew began stalking them.

After cornering them on a cliff, it almost succeeded in killing Beth after pinning her, but the twins were then saved by Hulk, who after reacting fearfully at The Makkapitew's existence, beats down and kills the Makkapitew by throwing it off the same cliff, breaking its bones upon hitting the rocks below and sliding into the mines.

A Year Later
Later, when Matt and Ashley wander through the mines, they come across The Makkapitew's decaying corpse laying on the ground, revealing that it did indeed die after its brief but brutal tussle with Hulk on the cliff; Matt surmises that it died from starvation or it fell from a high place.
