Heartwarming / Ben 10: Alien Force

  • Kevin embracing Gwen after she frees him from the horror of a transformation into Taydenite.
  • Gwen assuring Ben that she knows Julie would be thrilled to go out with him.
    • and Julie thinking Ben being able to turn into aliens is cool. She wasn't aware of the alien things at first, and seems to think his powers are cool. It was the first time since Kai that a girl knew about his powers and he sounded relieved that she found the alien things cool.
  • Gwen holding Ben in her arms when he nearly passes out in "Darkstar Rising".
  • Ben in "Alone Together". Pretty much everything he did.
    • Pretty much anytime Reinrassic III and Ben interact, knowing how much the latter has caused the former's character to develop from a racist supremicist to one of Ben's closer friends and staunchest allies. Added "D'awwww" points for Reinny's unintentional pet name for Ben: "BenbenTennyson."
    • Also when Ben returns to Earth and Gwen runs up to hug him. Even Kevin gave him a welcome with a ruffle of his hair.
  • The entire ending of "Voided". Period. To be more specific, not only does Ben save the world, but also he and Gwen find that Grandpa Max is still alive. Then, while Gwen is trying to get Ben back through the portal she opened, Kevin reaches in to help her and utters the following line:
    It's time to come home, Ben.
  • The last five minutes of "Paradox", where Paradox takes his assistant on a trip through time. Said assistant has been an outside-of-time force for a while and has just been brought down to an old man.
  • The ending of "Save the Last Dance". Discounting the weirdness of Ben playing Mr. Seahorse, those Necrofriggian babies are cute. And Kevin giving Gwen the honor of a private dance, even though they didn't make it to the school dance, just adds to it all.
  • Papa Wolf moment of Rath in "Con of Rath". After saving the little ice cream-like prince from a stomach of a newly introduced villain, he threatens to make a sweater from his ORGANS in case he declared war with another alien race. Also qualifies as the Crowning Moment of Awesome.
  • "Inside Man": Ben rescuing a DNAlien rogue from being taken back to their ship, along with two words: "No sacrifices."
  • Labrid's Heroic Sacrifice to save Kevin from a blast from the Forever Knights is Heartwarming in Hindsight. This could have led to Kevin's Heel–Face Turn since he started out as a weapons seller. In a way, Labrid inspired Kevin to change for the better.
  • Pretty much all of 'What Are Little Girls Made Of'. Specifically, while Verdona may have come off on the wrong foot with her grandkids in, she still loves her husband and came to their spot when she thought he had perished and, while she left, it was on better terms with their grandchildren than before.
  • In Grounded, Carl and Sandra show they care a lot about Ben's safety and, while they do keep him from doing what he needs to do, they do finally understand when Ben goes to save Kevin and even backs him up with a BAZOOKA! Also counts as a Crowning Moment of Awesome for Ben's parents.
  • 'In Charm's Way' has Ben and Gwen hanging out at night outside of Gwen's house. She then tells him she's going back to look for a cure for Kevin much to Ben's dismay of wanting to hang out a little more.
    • Later when Kevin badmouths Gwen, Ben defends her angrily.
  • In 'Time Heals', Ben buys Gwen some time to cast her spell, despite him already being hurt.
    "Do what you can. I trust you."
