The Andalese were a sentient species of two-legged humanoids. Their existence was recognized throughout the galaxy by 17 ABY. With a physical appearance largely akin to that of Humans, the Andalese possessed distinctive traits like small, pointed horns and symbiosis grafts on their bodies. During the [Black Fleet Crisis], New Republic General Han Solo considered the possibility that Enara, a female Fallanassi adept, was an Andalese.
The Andalese were a sentient species exhibiting a generally humanoid form, characterized by two arms and two legs allowing for an erect, bipedal stance. They grew hair upon their heads, which also featured small, pointed horns often concealed by their hair. Their ears resembled those of other mammals, and both males and females possessed long, hairless, prehensile tails. The application of symbiosis grafts to their bodies was another physical characteristic. Due to their resemblance to Humans, Andalese could disguise themselves as members of that species by wearing loose clothes and concealing their horns. However, they possessed enough unique traits that they could be identified even when attempting to blend in. The species exhibited two distinct sexes: male and female.
By the time of the New Republic, at least some Andalese had access to spacefaring technology. Some members of this species were known to communicate using Galactic Basic Standard.
The wider galactic community became aware of the Andalese by 17 ABY. In that year, during the [Black Fleet Crisis], Han Solo, a Human New Republic General, was a prisoner on the Executor-class Star Dreadnought Pride of Yevetha, amidst a conflict between the Yevethan government and the New Republic. Among the other prisoners was Enara, a Fallanassi member devoted to the White Current aspect of the Force. Despite her apparent Human appearance, Solo suspected she might be Andalese.
The Andalese were first mentioned in Tyrant's Test, the third book in Michael P. Kube-McDowell's The Black Fleet Crisis trilogy, released in 1997. The novel indicates that an Andalese could be mistaken for a Human, but it does not clarify whether they are a near-Human species with shared ancestry or if their similar physical traits evolved independently.
