- In the first episode, the original Digi-Destined's partners are getting brutally attacked by the Digimon Emperor, and Agumon cries out for Tai. What does Tai do? Drop everything and head to the Digital World to help his friend.
- Matt, Joe, and Sora do the same in later episodes.
- In the second episode, Izzy tells Cody that he reminds him of himself, and tells him to go to him with any problems he gets stuck on, so they can solve them together. Cody finds this very comforting.
- Mimi's reunion with Palmon in episode 6 can bring you tears of joy when you remembered that both were the pair that didn't want to separate the most in the previous season.
- Tai hugging Agumon in episode 11 after breaking him free from the Digimon Emperor's control.Tai: I'm sorry we attacked you, Agumon.
Agumon: I'm sorry too!
Tai: I'm sorry that you're sorry!
Agumon: Well, I'm sorry that you're sorry that I'm sorry!
Tai: Tell you what, I won't be sorry anymore, and you don't be sorry either, okay?
- In episode 13, when T.K. assured Kari, who had been on the verge of suffering from a Heroic BSoD due to the Dark Ocean playing on her inferiority complex regarding her brother, that she didn't just have Tai to lean on—she had him and the rest of her friends too.
- It's slightly sweeter in the dub, where it's implied the two may have feelings for each other, though the epilogue shows nothing may have came out of it.
- And then there was also poor Davis willing to find Kari by going to the Digital World on his own but the door wouldn't open.
- Even if there is another glimpse of Dragomon at the end, it manages to give a small sweet moment for what has been a Nightmare Fuel episode, with T.K. and Kari returning to the Digital World and an "everything-will-be-fine" smile in both kids.
- From episode 23, "Genesis of Evil". When Ken came into mind after his devastation for losing Wormmon, he went back to the Digital World. After recovering from a case of Laser-Guided Amnesia, and being told off by some baby Digimon. He has a total meltdown when he finally finds his partner Wormmon.
- In "If I had a Tail Hammer", Minomon's (Wormmon's pre-digivolution form) energy and enthusiasm while suggesting Ken exercise his excess dinner off is both funny and heartwarming. Because it shows Wormmon has since recovered from his past woobie status. The overall mood set by his and Ken's exchange of dialogue at this point shows their friendship as a whole has also recovered from the damage caused by Ken's role as the Digimon Emperor.
- Near the end of episode 26, "United We Stand". When the chips are down and it looks like the gang are going to be bug chow (it makes sense in context), Davis gives Ken a big speech about the Power of Friendship which activates their Digimon's power to combine.
- Even their lines in the dub manage to keep it heartwarming.Davis: Cool! I can hear my heart beating. Wait, that's Ken's heart.Ken: So this is what it feels like to have a friend. ...It's not half bad.
- Even their lines in the dub manage to keep it heartwarming.
- Ken's mom gets one of these too. Once she and her husband are bluntly made aware of their considerable screw ups concerning their treatment of their youngest child, the audience gets to see her as a mother who truly loves her son, and we start to realize how hard she's trying to make up for her mistakes. Anyway, after countless episodes of Ken's beating himself up, trying to atone alone, forgetting who he was, and generally going through so much crap that it became difficult to imagine he was ever the Kaiser, he finally comes round to the others attempts to help him. During one episode, Ken calls Mrs. Ichijouji to tell her he's staying at a friend's place, and she starts crying on the phone because the son she'd thought was trapped in a bubble forever and would never be able to deal with the social world finally has friends.
- Yolei sending a message to Ken's D-Terminal hoping to have him in the team. What makes it warmer is Ken reading it before going home. He turned back and saw Yolei's illuminated face."Dear Ken, I hope that someday you'll join the Digidestined. Signed Yolei."
- Chibimon and Minomon waking Davis up by playfighting on his bed is just So. Damn. Cute. You'll nearly explode watching it.
- Kari gets another one with Yolei this time on her next trip into the world of the Dark Ocean in episode 31, where she's literally falling apart and Yolei has to slap some sense into her, then tells her that it's okay, she's not alone and they're going to beat this together. A few seconds later, their partners Jogress Digivolve together into Sylphimon.
- All the other Digimon have fled in terror in front of BlackWarGreymon, but Agumon is content to sit with him and try to tell him about The Power of Friendship. Before the Destiny Stone cracks, the two are just about to shake hands as friends.
- Cody accepting an invitation to Ken's Christmas Party in episode 38. Look, everyone! They're on speaking terms!Cody: I'm glad I made your list!
- Ken's laughing in the Christmas episode, "A Very Digi Christmas". Not a maniac Evil Laugh like in his Emperor days but a genuinely happy one for the first time much to the others' astonishment, meaning that he stopped being an insecure, atoned and depressed child, enjoying the holiday with his new friends.
- Did anyone else go into full Squee! mode at how adorable that was?
- Also, see Ken's mom's reaction. What any kind parent isn't happy to see their depressed son having a good laugh and time with his new friends?
- The Christmas episode ends with a montage of the previous Digidestined having fun with their respective 'mons. And while a few are doing things privately, in other shots the parents are taking part; Palmon wears some lights to become a miniature Christmas tree, Tentomon eats dinner with the family Merry Christmas, indeed.
- The random civilian who tried to help Silphymon in episode 44. True he thought Silphymon was some guy in a costume, but he wanted to help her.
- Davis's speech while Ken is trying to close a gateway to the Dark Ocean (and is in considerable pain while doing so) in episode 45, "The Dark Gate" could be seen as heartwarming. The speech, plus the fact that every single one of the team is right there next to him helping him stay upright and encouraging him, is pretty damn moving even when the Dub does it.
- When the kids have had a rough day and are ready for Joe's brother to take them home, T.K. gives up his seat in the car for Ken. This small act of kindness shows us that the group has finally accepted him, and maybe by taking up the offer he's starting to accept himself.
- Ken and Wormmon's song, Honto no Tsuyosa. Ken and Wormmon reflect on how they've been through so much together, (The lyrics imply this takes place post Ken's HeelFace Turn), and Wormmon's Undying Loyalty even in the face of Ken's cruelty.
- Agumon, Veemon, and Wormmon's conversation with BlackWarGreymon after their battle ends in a stalemate and BlackWarGreymon confesses to being a Death Seeker;Wormmon: You're kidding me! That's what you're after?
Wormmon: You mean this whole time we've been chasing you around, watching you blow up everything blow-up-able, you just wanted to find something to destroy you? Don't you have anything better to do with your free time? "My life has no meaning, poor pitiful me." I know all about self-pity. When Ken was the Digimon Emperor, he treated me like fish-bait. I almost started to believe the awful things he said, but deep inside I had faith that someday the real Ken would come back to me. I just kept trying to get through to him! I didn't give up, and neither can you.
Agumon: Even if your life is all fighting and struggle, it can still have meaning. I've had to fight all my life, but I believed in what I was fighting for. I think it's that belief, not the fighting, that has given my life meaning. Can you imagine the trouble Tai would get into without me? If all you've got in life are lemons, make lemon pie! Hey, I'm hungry!
Veemon: And your life doesn't, you know, have to be filled with a whole bunch of incredibly amazing events to be special. Believe me, some of the best times I've had are just eating, and sleeping, and hanging out with my friends! and the thing is, we would all be your friends if you gave us the chance to be!
Wormmon: He's right. Look at Ken. He never thought he could have friends, and now he has lots of them. You just need to lighten up, give us a chance.
BlackWarGreymon: I don't know...
Veemon: Please don't go!
Agumon: Don't you want some pie?
BlackWarGreymon: This is all so foreign to me. I must think on it.
Wormmon: Are you sure?
BlackWarGreymon: I thank you for your advice.
Veemon: You're welcome.
BlackWarGreymon: Perhaps it is time to put aside my warrior ways. They have provided me few answers. And maybe one day, we can even be...friends. (Flies off)
Agumon: I hope so, BlackWarGreymon. I hope so.
- There is some subtle heartwarming in episode 49. Davis actually could have fallen in Malomyotismon's illusion due to his feelings for Kari. However, the fact that he didn't means that his affection wasn't possessive love and he is already happy at what they are now!
- A minor note, from the beginning of the series Davis loathed T.K. out of jealousy. By the finale their good friends.
- The whole series finale is made of this, even if you don't particularly like some of the last minute hookups it's great. Davis leading the charge against the Big Bad, with the power of wishing? Love it!
- Not to mention every single person on Earth gets their own Digimon. Seriously, every human has their own personal best buddy for life. How awesome is that? Kari fantasized about children and Digimon playing in harmony near the end of the season, comes true. And the Digital World even gets respected enough to be part of the United Nations! Seriously this is probably not just the most feel good ending of all of Digimon, but any show period.
- All this with "Bokura no Digital World" playing the background, a song where all the main characters thank the Digital World in their own little way for everything they've done and grown up to become, joining together in the choruses. Ai Maeda's solo rerecording is just as tingly.
- And then we learn that Oikawa has his own Digimon Partner, Datirimon, who has been waiting for him for about thirty years. Even though the former is dying, he comforts Datirimon that he shall always be with him forever as he transforms into butterflies and restores the Digital World.
- This troper found the uniting power of an entire planet's worth of Chosen Children right at the end of the second series tugged at the heartstrings quite a bit.
- This troper as well. A lot of people deride that scene, but it's amazing when you realize just how well-set-up that was- the only requirement to be made a Digidestined is to see a Digimon, and it's likely that, just like the new protagonists of 02, all those kids were supporting Tai and company against Diaboromon. Every single one. And then they get repaid in full by becoming chosen kids themselves and taking an active role in the final battle.
