Darth Vader
Anakin Skywalker was a Force-sensitive Human male who served the Galactic Republic as a Jedi Knight and later served the Galactic Empire as the Sith Lord Darth Vader. Born to the slave Shmi Skywalker in 41.9 BBY, Anakin was conceived by midi-chlorians, the symbiotic organisms that allowed individuals to touch the Force. He restored balance to the force by saving his son and destroying Emperor Palpatine.
StormTrooper
Stormtroopers were the elite soldiers of the Galactic Empire. Like Imperial-class Star Destroyers and TIE fighters, stormtroopers served as ever present reminders of the absolute power of Emperor Palpatine. These faceless enforcers of the New Order were considered an extension of the Emperor's will, and thus they often used efficient yet usually unreasonable tactics as a way to keep thousands of star systems throughout the galaxy in line.
Boba Fett
Boba Fett was a Mandalorian warrior and bounty hunter. He was the only unaltered clone of the famed Jango Fett, created in 32 BBY as unit A0050, one of the first of many Fett replicas designed to become part of the Grand Army of the Republic, and was raised as Jango's son. Jango taught Boba much, training him to become a skilled bounty hunter as was his father-figure before him. In 22 BBY, Jango was killed at the Battle of Geonosis, which opened the Clone Wars. Just a boy, Boba was forced to grow up and took to traveling the galaxy. Later, he became a bounty hunter and took assignments from beings such as Jabba the Hutt, and achieved notoriety despite his young age.
R2-D2
R2-D2, pronounced Artoo-Detoo and often referred to as Artoo, was an R2-series astromech droid manufactured by Industrial Automaton prior to 32 BBY. Resourceful and spunky, the droid developed an adventurous personality during his many decades of operation. Inside of his cylindrical frame were many arms, sensors, and other tools that could be extended to fulfill various needs, such as slicing computers, extinguishing fires, projecting holograms, repairing starships, and flying.
C3-PO
C-3PO was a bipedal, humanoid protocol droid designed to interact with organics, programmed primarily for etiquette and protocol. He was fluent in over six million forms of communication, and developed a fussy and worry-prone personality throughout his many decades of operation. After being destroyed and discarded on the planet Tatooine before 32 BBY, C-3PO was rebuilt; his salvaged nature gave him special qualities that distinguished him from similar droid models.
BB-8
BB-8 was an astromech droid who operated approximately thirty years after the Battle of Endor. The droid was at one point operating in the desert of the planet Jakku. It had a domed head, similar to that of R2 series astromech droids, with the bulk of its body made up of a ball that the droid rolled on. The droid belonged to Resistance pilot Poe Dameron, and thus was able to fit into a T-70 X-wing fighter's droid socket.
