Antimony comes off as graceful, relaxed, and mature on first impression, but this assessment couldn't be further from the truth. Sure, she's athletic, but her personality is comparable to that of an insecure teenage boy. She uses her extensive vocabulary to mock those that she deems less intelligent than herself, smugly assuming that they don't understand her. Truly, she isn't an expert when it comes to any subject. She only has slightly higher than average intelligence, and mostly uses it for sarcastic remarks and elaborate insults. One might admire her penchant for long-distance running, but she's only in it for the high that it brings her- it conveniently allows her to avoid thinking about her own problems.

Of course, she isn't all flaws. Among her peers, Antimony is regarded as very beautiful; she is a tall, strong woman with glossy hair and captivating eyes. She can be quite charming if she's in the right mood. And although she rarely makes friends or opens up to others, she is deeply protective of and caring toward the few people to whom she's grown close.
