Twizzl was a commander serving the Galactic Alliance Guard, the clandestine police force of the Galactic Federation of Free Alliances, which was under the command of Colonel Jacen Solo. He was a male Human with silver hair, native to the galactic capital world of Coruscant, and his speech reflected a Coruscanti accent. Throughout the Second Galactic Civil War, Twizzl served aboard the GAG Star Destroyer named Anakin Solo, participating in significant conflicts such as the Battle of Hapes, the Battle of Corellia, and the Battle of Gilatter VIII.
In the year 40 ABY, Twizzl was present during the Battle of Kashyyyk. During this battle, Solo gave the order for the Anakin Solo's crew to commence an orbital bombardment of the Wookiee homeworld, a directive that Twizzl deeply opposed. Simultaneously, the Wookiee Jedi Lowbacca launched a shadow bomb towards the ship, and Lieutenant Ben Skywalker attempted to assassinate Solo. As Lowbacca's shadow bomb impacted the bridge, Skywalker's attack occurred, resulting in Twizzl's unfortunate demise; he was bisected by Skywalker's lightsaber due to his proximity to the fight.
