Batman: The Brave and the Bold/Heartwarming

"AQUAMAN: Feels like a hug to me!"
 * In the episode where Aquaman and Atom team-up, a white blood cell snuggles Aquaman, who pets him in return. However, Atom pointed out the cell is sensing him to see if he's a germ that needs to be destroyed.

"Batman:
 * In "Invasion of the Secret Santas", Batman finds a present from Alfred, the nutcracker his parents gave to him years ago. Batman just smiles and thinks 'Merry Christmas' before heading off.
 * The Red Tornado finally feeling that Christmas spirit and becoming that much more human.
 * Also earlier in the episode, when Red Tornado tries his darndest to get that Christmas Spirit by setting up cheesy decorations and wearing an atrocious sweater, but especially when he gives Batman a mug that says "Worlds Greatest Detective" on it. Go on, say it with me: Aawwwwwwwwwwww!
 * In "Hail the Tornado Tyrant", Red Tornado sheds a single tear at the loss of his son. It's made even more heartbreaking when he says that it's 'oily discharge'.
 * Black Canary and Green Arrow's duet at the end of "Mayhem of the Music Meister!"
 * In "Gorillas in our Midst", B'wana Beast was insecure about not being a good enough hero to be dating Vixen. When Vixen wanted to talk with him, he believed she wanted to break up with him. Afterwards, at the end of the episode, when Vixen wants to resume the talk, he spills all this out and tells her to get it over with. She asks him to marry her.
 * Arguably, Babyface gets one in "Night of the Huntress", when he chews out his gang (and implicitly, by this stage, the audience) for making fun of his wife's looks.
 * "She's beautiful, see? A real looker! A honey!"
 * At the end of "The Power of Shazam!" when Batman does some investigation and finds Billy's long lost sister is very touching.
 * "Chill of the Night!" has to be the most intense episode of Batman the Brave And The Bold to date, but it also has a great heartwarming moment -- Batman is taken back into the past by The Phantom Stranger to a charity ball attended by his parents. He strikes up a quick friendship with his father, even helping him break up a robbery (which will lead to Thomas Wayne's death), but the real kicker is when he sees his mother, and all the tough, hard, no-time-for-emotions Dark Knight can do is hug her. Tightly.
 * In "Trials of the Demon", Batman, upon entering the past, meets Sherlock Holmes and has his identity perfectly discovered by a Sherlock Scan. Batman replies by jokingly identifying Sherlock based on his hat. At the end of the episode, Holmes asked Batman how he really knew who he was, to which Batman responded to his Real Life inspiration: "Everyone knows who you are. You're the world's greatest detective."
 * It's a given that "The Menace of the Madniks!" would have at least one when you see it's about Booster Gold traveling back in time to hang out with Ted Kord.
 * Hal and Carol beating Star Sapphire through The Power of Love.
 * The conversation between Ambush Bug and Batman. Borders on Tear Jerker.

Ambush Bug:

Batman:"


 * "Goodnight", in which we see almost every character, good and bad, have a little goodbye party, . All topped with Batman telling that, so long as evil exists, he'll be there to stop it even in.
 * From a production standpoint, they got Diedrich Bader's son to play the new Robin, Damian Wayne's son, alongside his dad playing the adult Damian Wayne at the end of "Knights Of Tomorrow!". If that doesn't make you go "awwwwwww"...
 * "Joker: Vile & Villainous" gives, surprisingly enough, one to the Clown Prince of Crime. It's oddly adorable seeing that even Joker has his heroes and and that he genuinely respects and CARES about the Weeper.
 * And it's much nicer than the comic it's based on (Joker #2 from the Silver Age) where the Joker just wants the Weeper to succeed so he can reap the spoils of the plan and drives the Weeper Laughing Mad. Here the Joker actually--in his own way--cares about the guy.
