Hill Valley's eccentric scientist, inventor the [=DeLorean=] time machine and Marty's best friend. He goes along with Marty in all of their adventures through time, fixing any changes to the timeline caused by time travel.

* {{Determinator}}: In the improved timeline, he kept trying for almost 30 years to get his first book published, [[EarnYourHappyEnding until he finally succeeds]].

* NiceJobFixingItVillain: In the first movie, Marty's [[EngineeredHeroics plan to pretend to be sexually assaulting Lorraine so George can save her]], doesn't go well because Lorraine actually ''wanted'' to jump Marty, and Marty got disgusted by it. It's only when Biff shows up and actually tries to rape Lorraine that George gets a real chance at saving the day.

--> '''Marty:''' Jesus, didn't that guy ''ever'' have hair?

* TookALevelInBadass: In 1985-A. He became a shotgun-wielding survivalist (presumably stemmed from his military combat training during UsefulNotes/WorldWarII as shown in an episode of ''WesternAnimation/BackToTheFuture'' when a young Strickland is shown as a MP back in the 1940s) because of the collapsing of civilization in Hill Valley.

* BaldOfEvil: He's completely bald in 1985, and when Marty is in 1955, he lampshades Strickland's male-pattern baldness.

* StereotypicalNerd: In the original timeline, George is a meek and introverted adult who wears NerdGlasses, has slicked down, side-parted hair, wears a button down and tie with a pocket-protector. When Marty goes back in time, he realizes that his dad has always been this way, on top of being an ExtremeDoormat and a BullyMagnet who is picked on by Biff and struggles to talk to his crush Lorraine. This does change though as Marty teaches George to stand up for himself.

* {{Nerd}}: Although Marty's intervention via time travel turns him into a much ''cooler'' class of nerd.

->'''Played by''': George [=DiCenzo=] (Sam) and Frances Lee [=McCain=] (Stella)

* WellIntentionedExtremist: Heavily {{Downplayed}}. Her intentions of keeping "hooligans" is good and all, but she goes about burning their places down just to ensure they don't come back again, which basically makes her no better than those villains she's fighting against. [[spoiler:Trying to have the nefarious Beauregard Tannen's saloon might be a good effort to fight crime in Hill Valley in 1876, but her arsonist methods of doing so ended up having ''the entire town razed to the ground''.]]

* WouldHarmASenior: Before Marty got involved, he shot Doc (who's currently in his mid-sixties) with a derringer, causing him a slow and painful death. The reason for it? Doc refused to pay him $80 after a horse he had shod threw a shoe and broke an expensive bottle of whiskey, because Buford had never paid him for the job in the first place. In the new timeline, he attempts to kill him multiple times.

* WouldHarmASenior: Before Marty got involved, he shot Doc (who's currently in his mid-sixties) with a derringer, causing him a slow and painful death. Oh, the reason?

* WouldHarmASenior: Before Marty got involved, he shot Doc (who's currently in his mid-sixties) with a derringer, causing a slow, painful death, over a thrown horseshoe which he never paid Doc for fastening in the first place. In the new timeline, he attempts to kill him multiple times.
* WouldHitAGirl: And did it to Clara, which roused Doc's ire considerably.

* BadAssDriver: For a 17-year-old kid, he actually does very well during the brief car chase and the clocktower run. In fact, he displays driving skills that are ''not'' taught in Driver's Ed or by his father George.

* GoldTooth: Had one in 1955.
