BB-8

In the original ending of Star Wars: The Force Awakens, BB-8 was supposed to join Rey and Chewbacca on their journey to find Luke Skywalker. Star Wars: The Last Jedi director Rian Johnson asked J.J. Abrams if R2-D2 could join them instead so BB-8 could remain with Poe Dameron, establishing where the characters would start in the film’s sequel.
