The dismembered arms originating from different species.
Limbs constituted significant anatomical extensions present on both biological beings and the constructed forms of droids. These major extensions encompassed legs, arms, hands, feet, and occasionally, wings or tentacles.
These anatomical parts were frequently vulnerable and subject to loss, potentially resulting from encounters with a lightsaber. Darth Vader experienced the loss of all his limbs, commencing with the First Battle of Geonosis and culminating in the Duel on Mustafar, which necessitated cybernetic replacements. In later years, Luke Skywalker suffered the severing of his right hand by Vader during the Duel on Cloud City, leading to a cybernetic replacement featuring artificial skin. Subsequent to the artificial hand being struck by blaster fire, Luke concealed it with a glove, a practice he continued until his later years when he abandoned it.
Trandoshans possessed the ability to regenerate lost limbs if they were severed. The Lasat named Garazeb Orrelios considered the possession of more than two legs to be "excessive." Within certain cultures across the galaxy, amputation of a hand served as a punishment for theft. The Scarif vault was isolated from the local computer network, permitting access solely through a right hand-print scanner. Certain species could occasionally be born exhibiting limb differences, exemplified by the human Captain Fennro Drogan, who was affected by phocomelia. This condition resulted in one of his arms being shorter than the other, and his hand possessing three fingers instead of the typical four.
