Heartwarming / Team Teen Cartoon Heroes Unite

• In Convergence at Gravity Falls, Dipper and Mabel seem to hit it off with Steven and Star. Dipper takes particular interest in Steven's half-gem nature, while Mabel seems amazed that Star is an actual princess and even gets to hug one of her Laser Puppies!
• In Resurrection, after Bill escapes, Stan looks at a picture at Dipper and Mabel, clearly worried about his nephew and niece. Ford places his hand on his brother's shoulders and smiles, assuring that they'll protect them.
  • Earlier, right after the battle, Ford helps Stan up after he got roughed around by Bill. It really shows how far the two Stans have come after their tumultuous reunion.
• Even prior to the events of A Quick Rescue, just the fact that Sonic, Speedy, Road Runner, and Turbo already know Rainbow Dash and consider her a friend and fellow speedster is really sweet.
  • After the fight with Skullker, Ben notices that the other speedsters are missing home, Rainbow Dash in particular lamenting how her friends back in Equestria might be worried. He says his friends in the Plumbers that can help them and even calls his cousin Gwen to pick them up.
  • When Ben leaves to help out the Crystal Gems in Beach City, Sonic decides to help him out as thanks for helping him and the other speedsters.
• In The Rematch, we have the reunion between the Mystery Twins and their two Grunkles. Too bad it gets ruined with the arrival of Aku-Bill.
  • Even though Rick constantly gets annoyed at Morty during the fight, he shows genuine concern for his grandson when he gets zapped by Bill's laser eyes.
• In The Battle of Beach City, Sonic and Amethyst share a fist bump when trying take out Tamatoa's legs.
  • While Rick turns down Moana's request to help Moana get back home (since her situation involves Time Travel, which Rick doesn't do), he does suggest seeing Professor Paradox about it, as he's more versed in time travel.
    • And sure enough, Paradox does help her out, as well as transport Tamatoa and the other monsters back to Moana's home time. Everyone also bids Moana farewell when she leaves.
  • Throughout his appearances, Ben has been somewhat appprehensive about being a part of Team Teen, preferring to be a solo act. Here, we learn that it's because, aside from thinking it was a one-time deal, Ben genuinely respects his new teammates and their accomplishments and he doesn't want to outshine them. Sonic convinces him to give it another shot, saying that even the best of heroes need help sometimes.
• In The Assembly, Kim praises the gathered heroes for their accomplishments in fighting the forces of evil on top of the already-troubling trials of growing up and thanks them for joining Team Teen in the fight against Aku.
  • Among the people we see in the crowd are Gwen and Kevin, Ron Stoppable, Brad and Sheldon, Sam, Tucker, Jazz, and Valerie, and Trixie and Spud, ready as always to help their friends fight Aku.
