Awesome / Team Teen Cartoon Heroes Unite

• In Convergence at Gravity Falls, various animated heroes team up to defeat a rock monster (which turns out to be a corrupted Gem that's been hounding Dipper and Mabel). And each hero is introduced via a Big Damn Heroes moment while accompanied by an instrumental cue of each hero's theme song. In order;
  • Steven Universe uses his shield to block the monster's tentacle roots from crushing the Twins. Once the monster breaks through the shield, it gets blasted to bits by a magic energy beam from Princess Star Butterfly of Mewni.
  • After the monster reforms into a ball and knocks around our heroes, it is then caught by Randy Cunningham. Then, they're joined by Sylvia (and Wander) and Finn (who comes through a convenient interdimensional portal), and they proceed to rough up the monster for bit before Finn pulls out Jake to deliver a big, crushing blow to it.
  • When the Gem monster reforms into a giant slab and uses the nearby trees to try and smash the group, they're saved by Danny Phantom and Jenny "XJ-9" Wakeman, with the former using his Ghost powers to shield everyone and the latter cutting the monster's tree arms with her buzzsaw. Then, Jake Long rains fire on it in his dragon form and Kim Possible comes in in her battle suit from So The Drama to deflect the monster's own fireballs.
  • Finally, all the present heroes (except the non-combatant Dipper and Wander) deliver one final smack-down to the monster and it's finally defeated, allowing Steven to bubble it up.
    • Even more cool the last 3 heroes who fire are Danny Fenton/Phantom, Jake Long/The American Dragon, and Randy Cunningham/The Ninja; the Secret Trio.
• A villainous example, but in Aku Takes Over The Multerverse!, the Master of Darkness makes one final, desperate attempt to save his own existence before Jack kills his past self and erases his dyspotic timeline; he calls his team of scientists to have them quickly access the Multiverse and send as many fragments of his dark essence to as many worlds has possible... AND IT WORKS!
  • The segment closes on the final image of Aku LAUGHING triumphantly as he's erased from his world's timeline, knowing that even after he's gone, he can rebuild his dark empire on other worlds and that he pulled off one last fast one on his mortal enemy.
  • The last segment in the short shows that Aku's efforts are starting to pay off as one his fragments has infected Raven Queen from Ever After High.
    • More of an Offscreen Moment of Awesome, as we only briefly see it here, but it's revealed in The Meeting that Star and Raven's classmates were able to free Raven from Aku's control.
• In Resurrection, Rick Sanchez, of ALL people, has captured an sample of Aku in order to study the demon. Granted, knowing Rick, he's probably treating Aku less as a big threat and more like an inconvenience he'd rather not deal with later, but it's awesome nonetheless.
  • Just when the newly revived Bill Cipher, courtesy of Aku, tries to kill Stan, Rick shoots him and fortifies his house to keep him from escaping. He even uses his in-body force field to repel Bill when he tries to grab him.
  • Ultimately, Bill wins by mind-controlling Rick (WITHOUT shaking his hand!) and has him deactivate the house's defenses. Bill then exits with a "Sayonara, suckers!" gesture to the heroes.
• A Quick Rescue has Ben Tennyson as XLR-8 teaming up with Sonic, Speedy Gonzales, the Road Runner, and Turbo to rescue Rainbow Dash from Skullker.
  • Once the others free Rainbow Dash, she wastes no time getting some well-deserved payback on the Hunter Ghost.
  • Ben uses his Diamondhead form to keep Skullker busy while the other four save Rainbow.
• The Rematch: it's Rick, Morty, and the Family Pines vs. Aku-Bill!
  • Rick reveals that he concocted some synthesized chemicals specifically designed to harm Aku! He even injects it into himself, Morty, and the Pines so that he couldn't touch them or take control of their minds.
  • When Bill takes control of Dipper and Mabel's fellow students and sics them on the heroes, Dipper uses the flashlight containing the size-altering crystal from "Little Dipper" to shrink them and safely contain them.
• Battle of Beach City gives Ben and Sonic showing up just in time to save Steven, Moana, and the Crystal Gems from an Aku-ified Tamatoa.
  • After everyone recovers, Sonic and Amethyst injure Tamatoa's legs to immobilize him, and they team up with Ben (in his Cannonbolt form) to defeat him.
• The Assembly: Kim and the Team gather a whole plethora of teenage superheroes to help fight Aku! While there's far too many to list on this one page, notable attendees include Anne, Luz, She-Ra, Ladybug, Cyborg, Spider-Man, Izuku "Deku" Midoriya, Leonardo, and MANY more!
  • In another universe, we see Fionna and Cake, Hiccup and Toothless, Darling Charming, Avatar Aang, Human!Twilight Sparkle, and Hiro and Baymax preparing to battle a fully-reformed Aku in his bird form!
  • Another villainous example, but in The Stinger for the episode, Bill has entered a "partnership" with BLACK HAT!
