Heartwarming: Ninjago

  • As of "Tick Tock", it turns out Zane is a Ridiculously Human Robot. For the other three, this doesn't make a lick of difference.
    • From the same episode, Zane's creator having a tearful goodbye with him as the old man is about to die, then wiping Zane's memories so he won't have to experience loss. Also a HUUUGE Tear Jerker.
  • The entire episode "Once Bitten Twice Shy" is this.
    • Heck, Jay and Nya's relationship in general is this.
  • Lloyd being reunited with his father.
  • Cole earning his father's acceptance of being a ninja rather than a dancer, then his father hanging a picture of the Ninja up claiming it's better than a trophy.
  • The ending to "Home".
  • Jay's parents offering to help the Ninja win the race they are all in because they heard why the boys were participating (in order to save a friends dojo).
    • Jay later taking a piece of his parents racer with him (after theirs gets totaled) saying that at least some of their car will cross the finish line.
  • Zane meeting his father again in "The Last Voyage", who was previously thought to have died.
  • Misako and Garmadon's first meeting in years in "The Last Hope," where it's apparent he still has feelings for her.
  • Garmadon turning good again at the end of "Rise of the Spinjitzu Master", with Lloyd, Sensei Wu, and Misako running to greet him, making their family whole again.
  • Zane reactivating P.I.X.A.L. by giving her half of his power core. Jay's mother certainly thinks it's heartwarming.
  • Skales and the other Serpentine starting families (Heck Skales even had a son.
  • Lloyd and his father growing closer over their exile.
  • Garmadon breaking his vow of peace because Pythor and the Overlord kidnapped his son.
  • Wu being freed from the Overlord's Mind Control and saving his brother..
  • Four words:
    Zane (to P.I.X.A.L.): Are we... compatible now?
  • Jay and Cole finally ending their feud in "Versus".
  • Cole seeing Zane in the prison cell, and his voice brimming with joy at reuniting with his friend.
    • Karlof covering for Cole just so he could see Zane. In fact, Cole and Karlof's interactions are just heartwarming in general.
  • At the end of "The Day of the Dragon", once all the competitors are freed they're all more than happy to unite with the ninja in stopping Chen.
  • In "The Corridor of Elders", when all of the people of Ninjago, human and Serpentine, stand together against Chen's Anacondrai army. Doubles as a Moment Of Awesome.
    • After the exiled Anacondrai return and defeat Chen and his army, they thank Lloyd for freeing them and giving them the chance to regain their honor.
    • Pythor of all people is given forgiveness, and a second chance to redeem himself by the Anacondrai generals.
  • "Winds of Change": Kai refuses to leave without Lloyd, and when Morro asks why, Kai claims he's made a promise to keep Lloyd safe, no matter what. Kai even managed to get through to Lloyd and might've actually rescued him, if not for the others dragging him away.
  • "Ghost Story": Nya as she will be the Ninja of Water, will finally be joining up with her brother to fight evil.
