History Tearjerker / BigHero6TheSeries

*** Look at Hiro's face during that scene. You ''know'', he's trying hard not to cry. The same goes for Callaghan. You see [[HopeSpot hope on his face that Hiro might forgive him for his actions]], but then Hiro tells him he needs more time. You know the instant the door closes behind Hiro, Callaghan probably burst into tears.

** As Hiro's friend give him a tour of campus, Hiro suddenly stops in front of... Tadashi's lab. Wasabi goes to comfort Hiro, and this sentence will pull at your heartstrings:

*** The instant he says that, everyone in the gang looks down sadly. Even the tough Gogo. It still makes you remember they lost a good friend, and they miss Baymax too.

** Hiro telling professor Granville the lab he's in is his brother's lab... or it ''was''. Though it goes to [[SugarWiki/HeartwarmingMoments heartwarming]] when Granville tells Hiro Tadashi Hamada was an excellent, hardworking student. It's her first "tough but fair" moment. We've just been introduced to Granville's character, and she already sympathizes with a kid who recently lost his brother.

*** It gets ''worse'' when you remember that he previously lost his father when he was a child and couldn't do anything about it, and that Megan [[LivingEmotionalCrutch is probably the only family he has left.]] But this time? [[ItsAllMyFault Megan gets taken by Trina because of his]] ''[[own actions]]''. This causes his change of heart towards Big Hero 6.

** Despite everything he's done, you can't help but feel bad for Chief Cruz when Megan gets taken away by Trina. He falls to his knees, [[AdultFear and fears for his daughter's life, who rests within the hands of a]] RoboticPsychopath.

'''Obake''': [[FamousLastWords I am satisfied with my care.]]

* In "The Hyper-Potamus Pizza-Party-Torium", Hiro and Fred are feeling sad when Wasabi, Gogo, and Honey Lemon are [[RealityEnsues pre-occupied with finding jobs]]. Seeing Hiro losing faith in them with they don't make it to a mission is heart-wrenching.

[[caption-width-right:350:When Hiro cries, ''we all cry.'']]

* The very fact that Hiro and the others may never get to live a normal life again, having lost Tadashi to a tragic accident as well as the increasing number of villains and other oddities threatening San Fransokyo.

Even if Big Hero 6: The Series focuses mainly on humor and action, it doesn't refrain them to drop tearjerking moments here and there.

** Upon recognizing the prodigious gifts of her student, [[spoiler: Bob Aken]], Granville gave him unlimited access to the lab, even after hours, only for her student to be seriously injured after one of his experiments went wrong. Blaming herself for allowing Bob to take his experiment so far, Granville, a respected teacher, stepped down from her job

** [=GoGo=] flyes into a terrifying TranquilFury and leads the team to give a NoHoldsBarredBeatdown to the poor Knox who is [[TheUnintelligible unable to clear up the misunderstanding]]. He can only howl in pain.

-->'''Hiro''': It's from Tadashi... [''grabs his head in despair''] and now it's gone!

-->'''Aunt Cass''': [''frowns at Hiro crying''] I miss him... ''so much''.
-->'''Hiro''': [''voice breaks''] ''Me too...''

-->'''Hiro''': [''voice breaks''] I do too...
** After expressing their sadness over Tadashi's departure and their first Christmas without him, Aunt Cass and Hiro share a hug, where both allow themselves to cry freely over their grief. Even the robot Baymax is seen lowering in head in sympathy. Try and watch this scene without feeling a jab in your heart, I dare you.

* "[[ChristmasSpecial The Present]]" being that this is the first Christmas without Tadashi.

** He just got his life on track, overcame his PowerIncontinence, found his purpouse and friends, and boom! Suddenly, his arm starts wreaking havoc by itself, and he can't stop it. He looks confused, horrified, and ''[[MyGodWhatHaveIDone guilty]]''. He can't explain anything to the police either so in a few hours, he goes from beloved hero to a wanted criminal again; only this time, he is afraid of himself.
** Felony Carl tells the heroes where they can find Globby OnOneCondition... they are to give him a big hug from Carl. Then, the tough guy sniffs, showing that he is really shaken by what happend to his friend.

* "The Present" being that this is the first Christmas without Tadashi.

'''Hiro''': I know, but I... I can't stand that he thinks he's right! It's not just that he's saying my work is junk. [''looks at a family picture with Tadashi'', frowns''] He's saying Tadashi's work is junk.\\
