Serleena Xath is a Kylothian from the planet Kyloth. Her alien form is a dark green slimey plant like worm with a head with no eyes and a mouth that splits open with four flaps like a flower. Serleena is also made up of all these tenticals that look like her main body that also have tiny head heads on the end of them. Using her tenticals that come out of her mouth she can morph into anyone she wishes by looking at them or an image. Serleena's alien form can vary sizes from being small as an earth worm to being large as an Elephant. While she's disguised as a human she has all the features but can also use her fingers and tongue to extend into her tenticals.
