BB-8

BB-8 is an original robot who debuted in ''Star Wars: The Force Awakens. ''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 R2 series astromech droids with the bulk of its body made up of a ball that the droid rolled on. BB-8 was mostly white with some some silver and orange on its body, as well as a black eye-piece. The droid belonged to Resistance pilot Poe Dameron and thus was able to fit into a T-70 X-wing fighter's droid socket. He replaces C-3PO and R2-D2 as the main robot character in The Force Awakens.

BB-8 was captured by the natives of Jakku, but they were ordered by Rey to release the robot. BB-8 then kept following Rey, despite the fact she refused to be followed by the robot. Rey was a scavenger who roamed Jakku for scraps of valuable metals in exchange for food. The Jakku "junkman" usually only gave out small portions for what Rey would find and offer, but he suddenly offered a large amount of portions if Rey gave him BB-8. She desperately desired the huge bounty of food, but didn't have the heart to let BB-8 die, which made the junkman furious and told the First Order (being led by Kylo Ren) about BB-8 and Rey. The First Order then attacks BB-8, Rey and Finn who commandeer the Millennium Falcon (though Rey wanted to infiltrate one of better-quality, which was blown to pieces) and escape Jakku. BB-8 then followed Han Solo and Chewbacca, when the latter two come aboard the ship.

BB-8 doesn't play a big role in the movie anymore following this scene, other than that he meets with C-3PO, who is depressed that his friend R2D2 has been offline for some time. C-3PO tells BB-8 that he blames Luke Skywalker's absence for this.

Personality
BB-8 is gentle and being a weak, vulnerable droid, refuses to be alone, relying on others for guidance and protection. He easily takes a liking to anyone who works for the Resistance, especially Ray, Poe and R2-D2. BB-8 is highly emotional, having displayed joy, sadness and fear throughout the film.
