Due to never being present as herself, it isn't easy to ascertain Cyn's actual mannerisms. That said, when puppeteered by the AbsoluteSolver, she comes off as a chilling personality that scares those around her due to her mental and physical deformities. Lacking any semblance of emotions, she resorts to using mimicry and imitation to behave like a real person would, speaking aloud her actions ("light sip," "sheepish nod," "giggle"), but she is capable of actually laughing. Her posture is weird.
