- The entire episode "Tick Tock" is basically this. Mainly Zane's creator dying right in front of him. Really, it was equal parts Tear Jerker, awesome, funny and heartwarming. If the beard hadn't sprouted before this episode, it's definitely come in now.
- The clincher: Despite being a robot, and therefore logically being Unable to Cry, Zane still sheds a Single Tear after it all comes back to him.
- Right after Dr. Julien turns off his memory, the blank expression on Zane's face, especially since his father dies literally seconds after, makes it even sadder.
- In the episode "The Home" Zane states that he never gets a letter from his parents. Well, now we know why...
- Sensei Wu as a child, and his confused, frightened expression as he watches his brother become consumed by evil.
- Garmodon is evil and he can't even control it. He is forced into doing bad things while he really doesn't want it that way.
- Because he is the prophesied Green Ninja, Lloyd will one day have to fight his father. It's clear that neither of them want this to happen, but the increasing control of the Overlord over his father made it inevitable.
- The Lloyd Garmadon's Blog is incredibly sad, despite its cheerful tones. The scene when he tries to steal the candy at the Jamanakai Village in the episode "Rise of the Snakes" was Played for Laughs, but when we get to read his point of view, the way he was treated at the school for Bad Boys and his reasons to steal the candy...No wonder why poor Lloyd escaped from the school several times.
- Lloyd: "Before I knew it, people were throwing rotten vegetables at me, and those Ninja tied me up to a sign. This was just like Finn all over again. I felt a single tear fall on my cheek, but then I thought that Finn might be right about one thing Ė evil geniuses donít cry!"
- After Lord Garmodon takes over the Serpentine, one of the Mooks suggests killing Lloyd. The look on Garmodon's face is heart-wrenching, as you can practically see him struggling to control the evil inside of him.
- Lloyd giving up his childhood to save his friends. A very literal example of Growing Up Sucks.
- After witnessing that Lloyd has become drastically older in "Wrong Place, Wrong Time", Lord Garmadon appears to be on the verge of a Villainous Breakdown, he looks completely heart-broken!
- Lloyd refusing to speak to his mother after meeting her for the first time in his life in "The Stone Army."
- Misako: Careful, son. That sinkhole has no bottom. It's where I found the Stone Warrior."Lloyd: Son? You've been gone my whole life! There's nothing you can say.
- In episode 25, the ninja are talking about their final battle together. It just seems so final, and they've been through a lot, making it just sad to listen to.
- All of the Ninja except Lloyd and Kai being forcefully being turned evil, then telling Lloyd to leave and save himself. They fortunately get turned back to normal in the end.
- After the Overlord's defeat, Ninjago City rebuilt itself to become a technological marvel, only for it to fall under the Overlord's grip once more with its technology acting as its arms and legs.
- Lloyd being helpless to save his father after being captured by Pythor and the Overlord..
- The shot of Garmadon sinking through the water does not help.
- Lloyd's face. Lloyd's face.
- Apparently, part of the Serpentine's reason for going underground was due to humans thinking that THEY were the enemy when they were just warning them of the evil Golden master. No wonder they're so bitter about the sealing bit.
- Really, just the entirety of the last seven minutes of "The Titanium Ninja": Zane pulls a Heroic Sacrifice (during which the viewer is shown his last memories, including his father telling him he was "built to protect those who cannot protect themselves") and is seemingly Killed Off for Real until the very last scene after his memorial shows he's still alive, just in Borg's systems.
- Zane's falcon perching on the statue and the snow that follows. If you weren't already crying, you are now.
- Then when Zane's voice asks P.I.X.A.L "Are we compatible?", a line P.I.X.A.L herself said when it looked like she would die earlier in the season, and the awestruck look on her face as she sees him again, and the swelling music with the light female vocals that send a chill up your spine... This whole scene may be full of Tears of Joy, but they are ripped from you like almost nothing else prior in the series.
- The first half of "The Invitation" is this, as it shows how the ninja are dealing with Zane's "death". All of them except Lloyd have given up on being ninja at all, and nearly decide to just end the team altogether.
- From "Versus", Zane finding out P.I.X.A.L.'s body was torn apart by Chen, leaving behind only her neural drive in a computer, and her insistence that he go on without her. This line just makes it sadder:
P.I.X.A.L.: I will always be a part of you.
- Jay and Cole's feuding reaches an all time high. As they both practice on dummies that have a picture of the other on them before their match, they each destroy their respective dummy. At first they both look satisfied. That is until the dust clears and they realize what their feud is doing to their friendship.
- When Chen reveals the secret of Garmadon's letter to Misako. Worst of all there wasn't any really practical reason for it. He even admitted he did it just to mess with Garmadon.
- Wu seemed to actually hate his brother for the first time in his life. It's subtle, but there's a scene where he gives Misako some tea, and Garmadon the cold shoulder. Wu does manage to forgive him for this when Garmado is banished to the Cursed Realm.
- This line:
Kai (to Skylor): Was it his idea to make me fall for you, or yours?
- The climax of the season 4 finale, when Garmadon is about to be banished to the Cursed Realm. Lloyd's reaction and the Really Dead Montage seal the deal.
- Keep in mind, LLOYD was the one who banished Garmadon to the Cursed Realm. The kid hardly knew either of his parents very well, and was forced to banish one of them to what was more or less a place worse than hell. No wonder the kid was off on his own for a while in Shadow of Ronin.
- In the first episode of season 5, Lloyd is possessed by Wu's bitter ex-student Morro who was released from the Cursed Realm when Lloyd had to banish Garmadon. In the ensuing battle with Kai, Lloyd briefly surfaces and begs Kai to help him. Poor kid.
- Not to mention Kai begging to go back for him when the others quite literally drag him away from Lloyd.
- Wu honestly liked Morro and his betrayal came of the whole Green Ninja deal that Kai and the others went through. Wu may have seen a repeat of his first student.
- Cole sacrificing his life to get the Airjitzu Scroll and becoming a ghost as penance. Not only is he technically dead, he also lost the ability to quote, "feel anything". Watching Cole cope and struggle with being bodiless deceased spirit is heartbreaking. Knowing that he will probably be a ghost forever makes it all the more worst.
- When the Ninja rescue Lloyd and return back to get their equipment for the upcoming battle, they meet up again with an old friend. However when he remarks on how they have all changed, when he mentions that Cole is now a ghost, Cole looks clearly distraught.
- The ninja defeat Morro, the Preeminant and all the ghosts, but Garmadon is now gone forever, and Cole is still a ghost. In addition, Wu's grief over losing Morro is quite sad.
Morro: You can only save those who want to be saved. Goodbye, Sensei.
- Yes, Nadakhan is a pirate and a Jerkass Genie but think about it: He lost the love of his life, and his home realm, Djinjago, gets destroyed because of the destruction of its sister realm, the Cursed Realm. You can't help but sympathize with the guy on those accounts.
- The way Nadakhan made P.I.X.A.L disappear when twisting the words of poor Zane's second wish.
- While Nadakhan is hit with the Tiger Widow Venom to slow him down, the Ninja see to their horror that Nya ended up getting hit with it as well. What happens because of this can easily qualify as one of the saddest moments of the series alone, even if Nya's death didn't stick. It hits even harder for Jay, who literally had to watch Nya die in his arms. The fact that Jay had gone through Character Development throughout the whole season as well as become closer to Nya makes this all the while tragic. Their last conversation together before Nya dies is truly enough to wrench a few tears.
Nya: You have to make your last wish! You're the only one who can stop him.
Jay: No! Not if that means losing you!
Nya: I never wanted to be a part of your... "boy's club", anyway...
Jay: No, Nya! Don't say that!
Nya: Guess it's true... the greatest love stories... do always end in tragedy... (dies)
- The TV Special, Day of the Departed focuses on Cole as he makes his final stand since he is fading from existence. It holds many emotional moments.
- When Cole starts to fade, his friends walk right through him; unaware of his existence. After this moment, Cole began to struggle with the idea that he is forgotten and possibly destined to be a lonely ghost.
- In his final battle with Yang, Yang taunts Cole, telling him that his friends and master had abandoned him. Although Cole refuses to back down at first, he is wore down by constant barrage of battles, which is unarguably against his favor, he eventually gives up and almost fades away for good; becoming so transparent, only a trained eye can see him and. Thank goodness they got there in time.
- A short moment, kinda played for laughs but Jay begins to cry when he realizes that Cole might be gone for good, but thankfully this isn't the case.
- Kai and Nya's parents, at some point, betrayed the Elemental Masters. And to make matters worse, this was to protect their kids; no parent should have to make that kind of choice.
- At one point, Lloyd's mother muses that she should have chosen Master Wu instead of Garmodon. Not only is this sad because Garmodon didn't ask for the reason she's reconsidering her choice since he was forced into evil, hating every second of it but in a roundabout way, she's wishing Lloyd had never been born because the person he became, for good or ill, was because who his father was and if Wu had been his father, it's entirely probable that there would be nothing of the Lloyd we know and love in the child who would have resulted.
- Cole saying "S- so we don't have a Master anymore??" after finding out that Wu had been lost to time.
