The Desserians are an extraterrestrial species with incredible chameleonic powers.
Evolving on an unspecified desert planet within the Migar System, the species who were to become the Desserians came from a line of non-predatory organisms, forcing them to develop extreme blending abilities. Because of this, a Desserian is extremely difficult to spot within a crowd, as they are capable of blending into social groups with ease.
Much of the flora on their homeworld is poisonous. As a result, their taste buds act as portable chemical laboratories to spot poisons before they enter the bloodstream.
It's assumed that Desserians have a healing ability, as Suudor was able to heal from a gunshot clean through his hand.
