Anarka sounds and talks like a pirate as she believes that chaos and disorder can be a good thing, which is shown when she tells Marinette Dupain-Cheng that she likes to keep her houseboat messy. Despite this, she knows when they are not, such as not allowing a metallic statue anywhere near the boat's compass, knowing metal makes it go crazy and thus useless. She also believes in freedom, even naming her houseboat “Liberty”. When Roger Raincomprix orders her to keep her music’s volume down, Anarka stands her ground as she believes that she should be free to be as loud as she wants for her concert. However, after she is de-akumatized, she realizes that she should obey the rules sometimes and keeps her volume down.
- Anarka is based on the word "anarchy", meaning "a state of disorder due to a lack of authority".
- Anarka's surname Couffaine is a combination of "couffin" (French for "coffin") and the French suffix "-aine" (meaning "of or from a place"), ultimately meaning "of/from the coffin".
- According to Wilfried Pain, Anarka is "the mother everyone wants, except when it's yours."
- Anarka's akumatized form was first revealed when concept art of her ship was shown during a Nolife interview.
- Later, her appearance was revealed from a press conference by TFOU.
- In response to a comment on Twitter, Thomas Astruc noted that, "in a way," Captain Hardrock is a reference to Captain Harlock from the manga series Space Pirate Captain Harlock.
- Both Captain Hardrock and her ship are a visual pun on musical piracy.
- It's unknown whether Anarka is married or a single mother.
- All the Couffaine's names so far end with "-ka".
- However, it is actually a pun, as a matter of fact in French it sounds like "acouphène" which means "tinnitus".
