Physical Appearance[]
XJ-6 is tall and thin, with green pigtails similar to Jenny's, except straighter, pointier, and more triangular, facing forward, and three insect-like legs that bend outward at the ends. She has only one arm. She has a computer monitor-like head which displays her face on its screen, with one green eye (she is occasionally seen with two eyes), and a jagged mouth which resembles an electrocardiograph’s readings.
Personality[]
XJ-6 is often subject to dishonesty, as she easily gets jealous, especially toward Jenny, seeing as she is the one saving Tremorton instead of her and her earlier sisters. This has been mostly demonstrated in Turncoats. She even becomes jealous when bad things happen to those other than herself, as shown in Sister Sledgehammer, when she was not the first to be absorbed by the Cluster-possessed Jenny.
