!!Back to the Future Part I
* Both times that [[spoiler: Doc gets shot in ''Part I''. Marty's reaction might be a little Narmy to some, but...imagine seeing your best friend killed in cold blood, ''twice'', and not being able to do a damn thing about it in either case.]]
-->'''Marty''': [[spoiler: [[BigNo NOOOOOOOOO!]] ''[[YouBastard BASTARDS!]]'']]
** And [[spoiler:the second time, Marty's reaction to thinking that Doc is dead is ''heartbreaking''. He just slumps back on the pavement and cries. He then looks up with an expression that screams "What am I going to ''do?''" ([[SugarWiki/HeartwarmingMoments not knowing, of course, that Doc is alive and sat up behind him]])]].
* It's subtle, but after the skateboard scene where Biff and his goons chase down Marty, he heads back to Doc's lab.[[spoiler:.. and finds that he made it to the end of the 1985 tape.]]
-->'''Doc''': [[spoiler:(on tape) Oh my god... They found me. I don't know how, but they found me... RUN FOR IT MARTY! (tape rewinds) Oh my god... They found me. I don't know how, but they found me... RUN FOR IT MARTY! (tape rewinds)]]
* The scene when Biff corners Marty, [[AttemptedRape and finds Lorraine in the car...]] At that point Marty sums up Biff's character in two simple words.
--> '''Marty''': Leave her alone, ''you bastard!''
** And when George finds Biff with her instead of Marty, the fact that she sounds so ''terrified''.
--> '''Lorraine''': ''(tearfully)'' George, help me! ''Please!''
* The moment where Marty [[spoiler: starts fading away]] and George looks like he's about to give up on Lorraine after a {{Jerkass}} steals her away during the dance, and Marty weakly, inaudibly pleads to George not to do so as he starts to collapse. It's less than a minute, but the intensity of that moment makes it feel so much longer.
* Marty hugging Doc goodbye before trying to get back to 1985. Now more than ever, his mind is on whether his friend will get the message. If he doesn't, this will be the last time [[spoiler: he'll see him alive]], and Marty knows it.
-->'''Doc:''' In about 30 years?
-->'''Marty:''' ''(briefly looks like he's about to cry)'' ...I hope so.
** And Marty can't even give Doc a proper goodbye, in case it really is the last time he'll see his friend alive, since Doc steadfastly refuses to listen to anything Marty has to say about Doc's future!
* Tears of joy version: the "Earth Angel" sequence where Marty plays the guitar among the band in order to make Lorraine and George kiss. [[spoiler: And he does succeed.]]

!!IDW Comics
* The entire concept of the 'Who is Marty [=McFly=]' arc. In this arc, Marty's own memories from the first movie doesn't seem to match with the memories of the timeline he's living. He starts to question if his [[FakeMemories are not real after all]]. Not only is he given a scare by [[spoiler:Marcus Irving, a fellow scientist who also invented Time Travel, but for the wrong reasons]] saying that Marty would disappear because he was originally the Marty of Twin Pines Mall, not Lone Pines.
** One of the most heartbreaking moments in these issues is when Marty gets kidnapped [[spoiler:by his own clones]] and he tells them that he was sorry for taking their lives away from them and that he wasn't the real Marty. He was so distraught by this that it almost seems that he was about to give up his life and just [[spoiler: fade away]]. It all turns out well in the end, but it doesn't make it less painful to watch.
** The dream (or rather, the nightmare) sequence that Marty has where he realizes that [[spoiler:the Marty from Lone Pines has returned]] and accuses him of stealing his life. Even worse, in his dream, Doc greets [[spoiler:the Lones Pines Marty]], completely ignoring Marty and the two watch Marty fade away. The scene ends up with Marty being startled awake and hugging his dad for comfort.
* The start of the Hard Time arc reveals that Marty actually had a very close relationship with his felony uncle, Joey. Marty even recalls some fond memories that they spent together. Marty even goes on a research rampage, trying to figure out what caused his favorite uncle to descend to such lows.
** There was even a little heartbreaking scene where a toddler Marty is boasting to his friends about his uncle's 'achievement' of stealing from the bank, only for his teacher to scold him. Marty's response really makes it sad:
-->'''Teacher:''' Martin [=McFly=]! That's not true, Martin. And anyway, what happened to your uncle is '''nothing''' to be proud of.
-->'''Young Marty:''' ''(Looks down with his hands behind his back)'' But I miss him.
