Front Information

Slattern is the only Category V Kaiju, which makes trump all of the other Breach Kaiju in both abilities and quality. She is extremely powerful and dangerous, and was used as a last resort weapon to the Jaegers when they were gradually making their way to destroy the Breach.


Main Article - [[1]]


Most of Slattern's return currently remains mostly unknown. She is mysteriously revived by an outside force. She is unaware of the Breach's destruction, which causes her to be able to operate on her own without the Precursors controlling her anymore. She is unaware of the destruction of the Breach as well as their kaiju. After she is revived, her intentions are to swim to a center of population, in hopes of finding clues.


Unlike the other Breach Kaiju, Slattern is less attracted to centers of population and is truly focused on destroying the Jaegers and all of humanity, as that retains her only mission. She greatly loathes humanity as a whole, as she has the most hate for humanity out of all of the Breach Kaiju. In battle, Slattern is mostly independent, believing her strength can take down her opponent(s). She has a dominant behavior in battles. When in need of help, she is highly cooperative and protective over her allies in battle when she needs them.


Slattern is a kaiju that is 150 meters tall and 181.6 meters long. Her whole body is a leathery reptilian-like structure. She has a relatively somewhat small mouth that is full of sharp teeth. She has two, diamond-blue eyes on each side of her hammerhead shark-like head. She has a sharp row of reptilian armor on her torso, accentuating the idea of her being the queen of the Breach Kaiju. She has two, large, and very muscular arms with sharp claws, as well as having two large muscular legs. Lastly, she has a trio of incredibly long tails that are triple-crowned on each of them.



Slattern is the strongest and most dangerous Breach Kaiju. She has a extremely high level of physical strength as well as speed, and a dangerous set of abilities. She forced two Jaegers to combat her after the other Category IV Breach Kaiju made their way to assist her in a battle against the Jaegers to protect the Breach. It's likely that it requires three opponents to take her down, while she can combat two at the same time.
