Cosmo (Chainsaw Man)

==Summary==
 is the Cosmos Fiend (の Uchū no Majin?), and was one of Quanxi's girlfriends and represents the fear of omniscience and gaining knowledge of everything in the universe. On the surface, Cosmo doesn't exhibit many emotions aside from her usual smiling, happy-go-lucky attitude. She doesn't speak except for repeating the word "Halloween" and, like the rest of Quanxi's fiends, follows Quanxi around and is in constant love with her and under her command.

Weaknesses: General Fiend Weaknesses, seemingly incapable of coherent speech outside of her mental space. It is heavily implied that the target needs to copy Cosmo saying “Halloween” after she says it, and possibly for there to be some kind of direct focus, in order to work.
Notable Attacks/Techniques:
*All-Out Halloween: Cosmo can telepathically send a person's mind into her own mind, which seems to be a dimensional space resembling a gigantic library. She then forces the target to understand everything in the universe, rendering them into a semi-catatonic state where they are "only able to think of Halloween until they die." Once this occurs, the victim will be unable to think or say anything other than the phrase "Halloween" until their death.
