Enixians have preternaturally heightened senses of olfaction, audition, and gustation. This ability can be seen as a double-edged sword, serving as both a blessing and a curse on planets such as Earth which has odors, sounds, and flavors that these ultra-sensory organisms are not familiar with "back home". An example is when an Enxian tried to kidnap Jess and Mel, only for Mel to use her personal alarm. Due to his heightened sense of hearing, the high pitched sound proved excruciatingly painful for the Enxian - allowing Jess and Mel to escape. Another is the fact that all Enxians wear sunglasses, even at night, due to their ultra-sensitive and alien looking eyes.
