Impy, as Roma calls her demonic conjoined twin in the 2009 TV series, would come out whenever Roma is angry or frightened and take control, whispering to her and trying to convince her to do vengeful and evil things. Although Roma is kind, she is powerless against the influence of her twin and a slave to its commands. Impy seems to have additional abilities over its sister when they have been separated, and in some ways is even more dangerous on its own. It can attach itself to others and hide in their flesh. Once bound to someone, it senses its host's emotions and influences their thinking with its hypnotic whispering, encouraging them to do the evil things they always wanted to do. When combined with another victim, it can still protrude from their back to make use of its tentacle-like limbs and claws, but is not as physically powerful as when combined with its sister.
