Batman Beyond/Heartwarming

"Terry: I read up on you, Mr. Wayne. I know how you lost your folks. The guy who murdered my dad is on that hover transport. This is my one chance.
 * Terry convincing Bruce in the pilot to let him stop Powers from shipping the nerve gas, and to confront his father's killer.

Bruce: ...the hoverpad is in the northeast sector.

Terry: Thanks. Wish me luck.

Bruce: ...good luck."

"Bruce: That kid's done a lot for this city. It's time for this city to do something for him."
 * A small one in the episode "Splicers" where Terry and Bruce's dog Ace have been having trouble getting along, but then Ace tries to save Terry while they are fighting a mutated Dr. Cuvier: "DON'T. TOUCH. MY. DOG."
 * Another Ace moment (yes, this show was so good that a dog largely included as a Continuity Nod got multiple crowning moments): After being attacked by the Joker, Ace convalesces by watching classic WB cartoons.
 * "Babel": Bruce's willingness to  is definitely an "AWWWWW" moment. Also, this:

"Bruce: Terry, I've been thinking about something you once told me. And you were wrong. It's not Batman that makes you worthwhile; it's the other way around. Never tell yourself anything different."
 * Bruce's final goodbye to  in "Out of the Past". Might also count as Tear Jerker depending on the viewer.
 * Fitting, considering it was the end of the series (until "Epilogue"), was Bruce's speech to Terry at the end of Return of the Joker:

"Bruce: What about your breathing problem?
 * The ending of the episode "King's Ransom" when.
 * In the episode where Freeze returns, Bruce is convinced that Fries is still a bad guy. Throughout it, he's warning Terry that Freeze is no good, but Terry stands up for him. At the end of the episode, after all he's seen, Terry says that Bruce was right... but Bruce says they were both right... indicating on some level he's forgiven Freeze.
 * A small one that always got to me is in the episode "Curse of the Kobra: Part II", Max has been kidnapped by the Kobra cult to be their queen and Terry is desperate to find her despite his myriad of injuries, including four cracked ribs that hurt when he breathes. When he and Bruce finally locate her whereabouts, there's this exchange:

Terry: (pulls on the mask) I'll breathe on the weekend."

"Terry: This kind of thing ever happen to you?
 * Terry and Melanie's caught in the rain moment. Usually this troper rolls their eyes at moments like this...but the music and their expressions, they were very genuinely happy to see each other it was just too sweet!
 * The first time Bruce called Terry by his first name. It hits you right then just how much Bruce cares about Terry and keeping him safe.
 * The bro moment between Bruce and Terry at the end of "Dead Man's Hand", after Terry watches Melanie/Ten get hauled away to prison:

Bruce: (smirks) Let me tell you about a woman named Selina Kyle..."

"Max: How do you do it?
 * In the episode "Final Cut" Terry is threatened with a bomb that could level an entire area of Gotham if he doesn't keep a member of the League of Assassins alive, when Maxine is attacked by the killer Terry, for the sake of a friend, risks all of Gotham to save her knowing that in his absence the killer could easily get to the man.
 * Not to mention the end of the episode after they both save the day:

Terry: (dabbing a wound on her forehead) It's easier for me. I've got the suit.

Max: No, how do you save the world and not tell anybody?!

Terry: I can tell you. You can tell me. That's why I'm glad you found out, partner. (they grin at each other and the episode ends)"

"Bruce: What're you smiling at?
 * The end of "Revenant" where Terry and Matt are going through pictures of a trip they took with their dad.
 * The end of "Mind Games", when the little girl Terry saved sends a psychic projection to him, just waving and smiling.
 * There's also a moment midway through the episode where Terry goes into Matt's room and pulls up his blanket over him as he sleeps. Aw.
 * Clark Kent & Bruce meeting for the first time in years, complete with Terry watching on.

Terry: Nothing."

"Max: I just wanted to be a part of something.
 * In one episode, a rogue AI is making all computerized things in Gotham- which is almost everything- go berserk. Terry discovers this while on a date with his girlfriend and they end up trapped on an elevator. After he stops said elevator, he is frantically fiddling with the controls in order to get down to the ground quickly so he can go check on Bruce. Bonus points for Dana not throwing her usual diva fit, but actually agreeing with him- and then turning it into a by slipping out of the elevator and saying she'd rather take the stairs.
 * At the end of "Rats" after Terry and Dana escape from Packrat's lair(under the guise of Batman), Terry shows up and starts to apologize to Dana(whom was mad a him for missing a date earlier) until Dana hugs him and tells him to shut up.
 * The entire "The Trigger Man" arc is about Mad Stan trying to reclaim his lost doggy. Preferably, with large quantities of explosives, but still.
 * The end of "Hooked Up" when Max apologizes for getting them both in trouble and Terry forgives her.

Terry: Well, congratulations, because you're a part of it now, but we'll take it a little slower next time."
