Three Monsters

Three Monsters are the three most dangerous and powerful creatures in the Great Forest of Tob.

Background
While the three creatures held no alliances nor comradeship, the group derived its names from the denizens of the Great Forest of Tob, who sees them as the strongest monsters within the region. These three monsters resided in the said forest, carving it into parts of their territories.

It's unknown how long the Three Monsters has ruled over the Tob Forests, according to a certain adventurer, the first recorded existence of one of the trio began around two hundred years ago.

While the three shared the Great Forest of Tob as a home, alliances among them were nil, and constantly fought against each other over dominance of the forest. However, despite their power, they entered into a stalemate for an indeterminate length of time, unable to get an advantage over one another.

As Hamsuke's territory lies at the edge of the forest near the closest human settlement, E-Rantel. She was the only creature among the Three Monsters to be documented by humans through tales and stories.

The Dark Warrior Arc
One of the Three Monsters makes it debut, when Ainz travels with a party of adventurers to the Tob Forest to collect herbs. He hears tales of a powerful beast, the Wise King, that is said to possess magic and the ability to speak. Believing that such a beast would raise his status as an adventurer, Ainz sets his eyes to capture it. Sadly the 'beast' was just a giant hamster, though the Overlord decides to keep it due to it being a creature of reverence by the New World inhabitants. Christening it the name Hamuske the beast became Ainz's loyal pet and steed.

The Two Leaders Arc
It was later revealed that Hamsuke was just one of a triad of monsters that collectively ruled the forest. After her disappearance and Nazarick's infiltration, the power balance in Tob Forest became severely altered. The two remaining leaders of the forest seeing that their rule was threaten by an outside forced decided to put their centuries old grudges aside and stand together.

Strength
The Three Monsters were terrifying existences enough that they earned themselves the respect and fear by the Tob Forest inhabitants. They ruled the forest with fear and destroyed any that dared to enter. On average, all three of them were estimated to be around level 30.
