a lot of time visiting the Brown house where Doc, Clara, and their sons live. He continues to travel through time alongside Jennifer, Doc and the rest of the Brown family on many of their misadventures. Marty and Jennifer become students at Hill Valley College after graduating from Hill Valley High School. Jennifer Parker (voiced by Cathy Cavadini) – Marty's girlfriend. Emmett "Doc" Brown (portrayed by Christopher Lloyd in live-action segments, voiced by Dan Castellaneta in the animated segments) – Marty's middle-aged best friend and the inventor of the DeLorean time machine, which he built out of a DeLorean sports car in 1985; he subsequently built a locomotive time machine from 1885 to 1895. In the first episode of the series, the DeLorean is apparently being rebuilt with added features, nodding to the events of Back to the Future Part III. He lives with Clara and two sons Jules and Verne. Einstein (voiced by Danny Mann (season 1) and Hal Rayle (season 2)) – the faithful sheep dog living with Doc, Clara, Jules, and Verne. He is also Marty's friend. Clara Clayton Brown (voiced by Mary Steenburgen) – Doc's wife, who, along with the rest of the family, moved to the 20th century. She and the Browns lived in a farmhouse outside Hill Valley in 1991. Clara's embracive nature has meant she's settled well into 20th-century life and became a teacher at Hill Valley Elementary. She occasionally joins her husband, sons, and Marty on their time travel road trips. Jules Brown (voiced by Josh Keaton) – Doc's eldest son; his middle name is revealed in the series as Eratosthenes.

He has a crush on his classmate Franny Philips and enjoys baseball and inventing, often helping his father crack down conclusions. Verne Brown (voiced by Troy Davidson) – Jules' younger brother. He is charming and adventurous but fairly vulnerable, not taking well to losing out or things he doesn't particularly enjoy doing. He is almost always seen wearing a raccoon skin cap which he clearly loves and
