[[WMG: Hibiki's DefrostingIceQueen act [[ManipulativeBitch is just an act]].]]
She's been training to be the perfect spy since birth, and emotional manipulation is one handy tool. There's also the fact that she passed for normal before her cover was blown.
* Her current behavior appears to be sincere, although she's a pretty good actress.

[[WMG: Hibiki is being sincere but after her defection becomes known [[CloningBlues she'll get replaced by one of her "sisters"]].]]
"'Hibiki'? I killed her [[Comicbook/{{Watchmen}} 35 chapters ago]]."

[[WMG: Hansel is one of Hibiki's clone-siblings and Hibiki is Gretal.]]
Hibiki said her fellow clones ''looked'' alike; she never said they were all sisters.
** Jossed. Hansel isn't related to Hibiki and Gretal happens to be that incompetent schmuck in Third-I.
