Niebur Boton was a Jedi Knight of the Zeltron species, identified as female, who served the Jedi Order in the waning years of the Galactic Republic.
A Force-sensitive female Zeltron, Niebur Boton was trained in the abilities of the Force by the Jedi Order. After a period of learning, Boton underwent her Trials of Knighthood and was elevated to the rank of Jedi Knight.
As the Clone Wars broke out across the galaxy, Boton participated as a General in the Grand Army of the Republic. In 19 BBY, near the conflict's conclusion, the Republic's Supreme Chancellor Palpatine enacted Contingency Order 66 to the clone troopers of the Army, a directive which commanded them to assassinate their Jedi superiors. Boton initially survived, but was eventually captured by the newly formed Galactic Empire. Tortured by the Inquisitor Antinnis Tremayne, Boton eventually gave in to the intense interrogation and revealed the identities of several of her surviving Jedi allies. Boton's life ended soon after, and her remains were transported to Coruscant by Imperial stormtroopers. Awaiting the body at the landing site, the Dark Lord of the Sith Darth Vader seized the deceased Jedi's lightsaber and desecrated her corpse with it.
