Question: What Norse mythological figure is the basis for the lead female superhero in Fearless Defenders?
Context: The "Siegfried" class was a group of six coastal defense ships built by the German "Kaiserliche Marine" ("Imperial Navy") in the late 19th century.

The class comprised the lead ship "Siegfried" , along with her sisters "Beowulf" , "Frithjof" , "Heimdall" , "Hildebrand" , and "Hagen" .  All six ships were named after Norse mythological figures.

Likhoradka (Russian: "Лихорадка", Serbian: "Милоснице" or "Milosnice") or tryasavitsa is a female spirit in Slavic mythology.  Likhoradka was purported to be able to possess a person's body and cause sickness.  In some tales, she is considered a creation of the dark deity Chernobog.  Later Russian legends describe 12 Likhoradkas, with individual names associated with special illnesses.  In modern Russian, the word likhoradka has obtained the meaning "fever".  As a mythological figure, Likhoradka was related to the figure of Chuma, which in modern Russian is the term for plague.  Likhoradka was sometimes portrayed as a tall woman with dishevelled hair, a pale face and a white dress, who brought sickness to people she tried to touch or to kiss.

In modern times, scholars established a standardized spelling for the language.  When Old Norse names are used in texts in other languages, modifications to this spelling are often made.  In particular, the names of Old Norse mythological figures often have several different spellings.
