Avengers and Trollhunters is a Trollhunters and Marvel Cinematic Universe Crossover fanfic written by cg99 which can be found here.

In the wake of the Battle of Manhattan, S.H.I.E.L.D. detects signs of dimensional portals in Arcadia, California. Fearing that Loki has somehow returned, they dispatch the Avengers to investigate. But it is not Loki behind those portals, and this investigation will bring a hidden war and a hidden world to light.

Tropes To Be Found In This Story:

  • Berserk Button: While none of the Avengers are happy about the Trollhunters putting themselves in danger while still children, Tony takes it far worse than the rest. Nick Fury notes that the S.H.I.E.L.D. Psychologists put this down to his experiences in Afghanistan.
  • Department of Child Disservices: In the second arc, General Ross threatens Claire with having CPS take away her baby brother on trumped-up charges if the Trollhunters don't "voluntarily" join the military and put themselves under his control.
  • Drama-Preserving Handicap: In the second arc, the Trollhunters are forced to surrender the Skathe-Hruin, Toby's warhammer, and the Eclipse Amulet as a result of General Ross's manipulations, and thus have to face the museum robbers with only their trained skills and whatever they can improvise.

  • The Dreaded: The trolls last encountered Thor many centuries ago, when he was still Odin's sword arm and led the Asgardians to war against the Gumm-gumms. Unsurprisingly, the trolls are terrified of Thor to this day, more than they are even of Angor Rot or Gunmar.
  • Emancipated Child: Unusually for this trope, it's the parents' idea to have the Trollhunters do this and the purpose is to defend them against third-party interference. The parents themselves had already (reluctantly) accepted their children's status as Trollhunters by the time this came up. Jim is actually very upset at the idea, being devoted to his mother, but she points out that it's not like he was planning on disappearing when he turned 18 anyway.
  • For Want of a Nail: Due to the intervention of the Avengers and S.H.I.E.L.D., pretty much all of Trollhunters canon from the end of Season 1 onwards is thrown out the window: Angor doesn't attack Trollmarket and get killed, instead having a Heel–Face Turn after getting his soul back; Gunmar is killed before his army ever leaves the Darklands; Usurna's treachery is exposed and she's killed much sooner; and Morgana is still sealed.

  • General Failure: General Ross, whose first reaction upon the Trollhunters' identities being revealed is to use a patsy to take away their tools and try and press-gang them into military service with a combination of obviously trumped-up charges and threatening Enrique.
  • Good Is Not Nice: As Jim notes, Angor post-Heel–Face Turn is still a scary troll.
  • Let's You and Him Fight: The Avengers are only in Arcadia because they picked up the energy from Claire's shadow portals and mistook it for some sort of backup plan of Loki's. Therefore, they're already on edge and quick to confront Jim and his friends when they realize the group is hiding something; the teens, already paranoid about potential Changeling infiltration, just as quickly lash out when confronted, leading to a fight that results in Claire getting hurt before anyone can calm things down.
  • The Man Behind the Man: The one who nudged General Ross into doing his actions in the second arc was Pierce and HYDRA, who wanted to make the world seem unstable as a way to push forward the new Helicarrier program seen in Winter Soldier.
  • Superman Stays Out of Gotham/Story-Breaker Team-Up: Specifically Averted. The author has mentioned that one of his goals in this story was to write a crossover in which the two sets of protagonists have wildly differing power levels, without artificially equalizing their powers or letting one group get sidelined by the other.

How well does it match the trope?
