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
According to Dustin, Queen Taratects are unique even amongst other legendary-class monsters. That being that they acquired their strength by leveling-up and evolving, whereas other legendaries were simply created with all of their strength by either D or Güliedistodiez. Perhaps as a result of the battle experience that came with this, the species is generally regarded as the strongest in the world, with it taking a combined effort of multiple other legendaries just to take down a single one.

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 an imitation of a Queen by having one of her clones take on the appearance of one. It was not quite as strong as a real Queen but even so its stats were much higher then a Hero, with the previous Hero, Julius, not being able to do any damage to it. It did have a glaring weakness, however: the eyes, which held no defences whatsoever. Julius eventually realized this and used it to slay the beast with one of Wrath's exploding swords and help from the army tasked with defending fort Kusorion. However it was later revealed that the imitation Queen was holding back since its goal was not to slay Julius but instead have him use the sword of the hero.

Known Individuals

 * "Mother": a Queen living in the depths of the Great Elroe Labyrinth. She is considered the strongest monster native to the Great Elroe Labyrinth and the original progenitor of all spiders native to the Labyrinth.
 * Another queen lives in the forest nearby the Elf Village.

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.
 * In a similar case, due to Ariel's deep seated hatred and contempt for Potimas and by extensions all of his elves, all of the Queen Taratects also possess a deep murderous instinctive grudge against the elves and would slaughter them on sight.
