Mercury often maintains her original red hair, suggesting that she has the ability to change her mercury's color and texture to a degree. Electricity is her main weakness and has often been used against her, because it causes her body interference. Due to her composition Mercury does not require food or drink. Only a few people know this, as Mercury "eats" to make herself feel more normal and to be able to interact with other people. Since her body is not organic, she is one of the few people who can touch Wither - for whom she has unrequited feelings - without decaying. Her inorganic body also made her immune to the pheromone based powers of Wallflower and was placed as her roommate. She can also control pieces of her liquid mercury and has the potential to bring it back to her like she almost did in the last issue of Mercury Falling. Usually, if forcefully separated from her body, her liquid mercury turns into dead flesh, as demonstrated during the Facility's experiments. Some of her mercury has been separated as living mercury tissue and was used for Predator X's skin. She is currently less than her original mass, as she states that when Laura cut off her hands to save her during the fight with Nimrod, she "lost a few pounds." Due to her transient form, she has some resistance to magic.
