Queen Taratect

The Queen Taratects are massive spider-monsters. It is said that an ancestral Hero, with his army, sacrificed themselves in order to defeat a single queen. There are only five alive in the entire world.

Monster File Description
A queen that reigns as the most powerful of spider monsters. Boasting a size so large it can cause destruction just by walking, it is said to be powerful enough that even a single individual can destroy an entire country. Even an army cannot defeat a queen taratect, yet the queen often uses Egg-Laying to increase the number of its minions. There are only 5 in the entire world, each of them considered the most powerful monster in its area. A legendary-class monster that cannot be defeated by humans.

Synopsis
One of the Queen Taratects gave birth to Kumoko. This one is nicknamed "Mother". Kumoko tries to avoid her as much as possible due to her extreme violence and power. Kumoko meets her again in the Middle Stratum of the Great Elroe Labyrinth and again when Kumoko leaves the Labyrinth.

Mother attempts to kill Kumoko because Kumoko's parallel minds are eating at her soul. She is personally killed by Kumoko in a weakened state, reducing their total global numbers to four.

Volume 12 Spoilers Shiraori later creates a fake Queen by having one of her clones take on the appearance of one. While it's power was only a fraction of the real deal, it was still able to easily overpower the previous Hero, Julius. Despite this, though, it was ultimately slain when Julius attacked it through it's weak point: the eyes.

Trivia

 * Despite having the advanced Black Magic, both Mother and the generic Queen Taratect lack the Magic Power Operation skill. This is probably an error, seeing as Mother is shown using Dark Magic.
 * Due to Ariel, their progenitor, possessing a deep hatred and grudge towards Humanity due to their foolishness and arrogance that is being payed for by her adoptive mother Sariel's suffering, the Queen's Taratects where stated to have inherited their "mothers" hatred for humanity deep in their souls.
