"And there came a day unlike any other, when the heroes of the multi-verse found themselves united against a common threat. On that day, they became the Avengers."

Summary for Avengers of the Multi-verse

Avengers of the Multi-verse is a series of mega crossover fics between Danny Phantom, Sym-Bionic Titan, American Dragon: Jake Long, Ben 10, Generator Rex, The Secret Saturdays, and Kim Possible created by Iron117Prime.

It should also be noted that the author incorporates various aspects from popular fanfic writer Aaron12's various series into this, like Sam being a halfa and Kim and Jake having met each other prior to the series.

Season 1 was completed with nine full episodes and a prequel story. After the completion of the first episode of Season 2, the writer chose to put the series up for adoption due to an overload of work from handling multiple stories, with intent upon supervising and co-writing while another does the main writing. The writer to take over was announced to be UltraPhantom in February 2024, with their first story being published in April of that year.

---

Avengers of the Multi-verse provides examples of:

Season 1

• Action Girl:
  • As per canon, Kim and Ilana.
  • In Episode 3 we get to see Sam (now with ghost powers) and Dani in action.
• Actor Allusion: In Mission Possible, Zack notes that Shego sounds almost like his mom. Drew Saturday and Shego are both voiced by the same actress: Nicole Sullivan. In A Nightmare at Weird World, Kim and Ron make the same comparison.
• Always Second Best: Rex uses this to taunt Albedo during their fight in Clash of Titans, pointing out that he's always second to either Ben, Azmuth, or Vilgax.
• The Archmage: The Archmage of Atlantis has his ghost summoned by Chang, which is powerful enough to give Max a serious run for his money.
• Atlantis: In Jake, Kim, and Ron's world, Atlantis was the first civilization to use magic, their signature being Creating Life. The Leviathan was made to defend Atlantis, but turned against its creators and destroyed Atlantis, forcing it to be sealed away.
• Badass Family: The Saturdays, which is even commented on In-Universe. To give a quick run down, their son Zak is a member of the Avengers, his 'siblings' are cryptids with powerful abilities, the parents were able to give Kim and Rex a good fight respectively while Brainwashed and Crazy, and Zak's uncle was capable of infiltrating Weird World on his own on several occasions and come out unscathed.
• Badass Normal: Kim is the only member without powers, but still has excellent martial arts skills and extensive experience in stealth. Furthermore, her battle suit actually gives her some abilities including force fields, energy absorption, and (as of Episode 3) the ability to bypass intangibility, making this a Downplayed Trope.
• The Bad Guy Wins:
  • Episode 1: A Home Away From Homes, the Mutradi Phantoms are defeated, but Modula is able to gain access to the knowledge they stole about the Avenger's powers and histories and manages to gain access to the multiverse.
  • Episode 5: War of the Worlds, while his invasion of Galaluna was stopped, Vilgax and Psyphon managed to acquire the schematics of Illana's Corus armor and they gained data on Titan.
  • Episode 6: Deus Rex Machina, Van Kleiss manages to both getaway but also get a sample of the energy that powers Octus, as well as his schematics, presumable to make an Evil Knockoff of him with.
• Bash Brothers: Given the nature of the team this was bound to happen. Special mention goes to Ben and Rex, who remain good friends from their previous team-up and enjoy beating up bad guys together.
• Battle Couple:
  • Kim and Ron are an Official Couple and both are martial arts masters capable of kicking lots of ass individuals or together. In addition, years of going on missions together mean that their teamwork is excellent.
  • Downplayed with Danny and Sam. While they both have powers and are great at fighting ghosts, we have yet to see them fight together.
  • Jake and Rose are a shapeshifting dragon and a former Hunstclan that are in a committed relationship. Dawn of the Dragons shows the two also have impressive coordination in battle, launching simultaneous attacks on the Yowie Yahoo.
• Battle in the Center of the Mind: In Dawn of The Dragons, Zak uses his power against the Dark Dragon's mind-control powers on the Guardians of the keys to the Leviathan's prison.
• Battle in the Rain: Most of Titan's battle with the Leviathan takes place underwater, but briefly they fight above the ocean's surface in the middle of a storm.
• Behemoth Battle:
  • When faced with a trio of Mutradi Tri-Beasts, the Titan crew form the titular robot, while Ben deals with another as Way Big.
  • Titan is also used to go up against Vilgax's giant robot of himself, the Leviathan, and its own Evil Knockoff, Goliath.
• Big Good: Paradox and Clockwork are responsible for organizing the teams meeting in the prologue. Likewise, Solomon provides them with their base and information about any crises as they occur.
• Body Backup Drive: Argost is now back in a Yeti body, a clone of his original.
• Brainwashed and Crazy:
  • Breach for much of Deus Rex Machina is under Van Kleiss' control thanks to the mind control collar. Danny manages to free her during the Pack's assault on the G3 base.
  • In Nightmare At Weird World, Argost uses Neural Parasites on Doc and Drew, which, combined with his Anti-Kur powers, allow him to control them.
• The Cavalry:
  • At the climax of Dawn of the Dragons, just as the Avengers are being overwhelmed by the Dark Dragon's army of Huntsclan ghosts, Lao-Shi shows up leading the combined forces of all the world's dragons (as well as Jake's friends Spud and Trixie), who help turn the tide in their favor.
  • The first fight in Clash of Titans ends with G3 swooping in via Gunship Rescue to save the Avengers from Goliath.
• Combat Pragmatist:
  • During the battle against the Mutrad Tri-Beast, Danny bypasses its thick skin by phasing inside of it and unleashing a storm of ecto-blasts on its internal organs.
  • When faced with Baron and Skulker, both of whom rely on power armor, the team opts to simply have Danny use intangibility to knock the former out of his, and Rex uses his technopathy to deactivate the latter.
  • When fighting the Brainwashed and Crazy Doc Saturday, Rex gains the upper hand by using his technopathy to disable his power glove.
• Combination Attack: During the battle against Vilgax in Episode 5, Danny and Ben deliver the finishing blow by combining the former's Ghostly Wail with the latter's sonic scream as Echo Echo.
• Combo Platter Powers: Particularly applies to Danny and Ben as the two most powerful members of the team; Danny has the widest variety of individual powers, but Ben has more raw potential with his various alien forms even if he can't access all of those powers at once.
• Crazy-Prepared: Surprisingly, Drakken of all people. He brings improved syntho-drones as hidden back-up each time he goes to steal something, has improved his hovercraft for remote summoning and high speeds for a reliable get-away plan and to cap it all off, keeps his plan secret from everyone (including Shego) to ensure countermeasures can't be made ahead of time. He even had a ten-second self-destruct switch installed in his lair for a distraction in the event that his plan failed and he needed to make a quick escape.
• Curse Cut Short: Upon discovering Van Kleiss used a Providence collar on Breach, Rex has some choice words for him, before the Pack starts attacking him.
  Rex: You sick piece of...
  Van Kleiss: Now, now. You need to watch that temper of yours. Biowulf, Skalamander, please teach him some discipline.
• Damsel in Distress: Ilana gets captured by Psyphon and needed to be rescued by Rufus when he snuck along. She's also aware of how she tends to be this and is rather self-conscious about it.
  Ilana (to herself): Why am I so helpless all the time?
  • She lampshades this again in Clash of Titans, asking Kim for help in training so she's not helpless outside of her armor.
• A Day in the Limelight: Each episode from Ghost Busting to Dawn of the Dragons focuses on one member(s) of the team.
• Didn't Think This Through: Discussed after the Avengers learn about the circumstances that led to Vlad exposing his true nature during "Phantom Planet"; Kim states that even some of her villains would have a back-up plan to something that big rather than pin everything on a single scheme.
• Divide and Conquer: Goliath is finally defeated by the Titan team exploiting Shego and Baron's dislike of both each other and Novex, eventually causing their combination to fall apart.
• Dual Wielding: Zak starts to do this with the Claw and the Fang after taking the latter from Argost.
• "Eureka!" Moment: At the start of Clash of Titans, the Avengers discuss their string of recent adventures and deduce that their enemies are working together.
• Even Evil Has Standards: Shego refuses to kill, which prevents Goliath (which she's part of) from finishing off the Avengers in their first fight.
• Everyone Can See It: More than one character has commented on or teased Ilana or Lance about their presumed relationship.
• Evil Cannot Comprehend Good: When Albedo is going over the data the Cabal has on Octus, he discovers that the robot was designed to develop emotions. The members openly scoff at the idea and ensure that Novex will act based solely on logic.
• Evil Knockoff: It's revealed that the allied villains are creating one of Titan, code-named "Project Goliath", powered by an evil version of Octus called Novex. Shego wields a knockoff of Ilana's armor in Goliath, while Baron takes Lance's role..
• Fire-Forged Friends: There is initially some friction between Ben and Ron (as mentioned below in Let's You and Him Fight), which they work past while storming a Mutradi base, aided by the fact that Ron temporarily believed Ben had died and was relieved when he turned out to be alright.
• Fights Like a Normal: Because Zak's powers only work on cryptids, they're basically useless unless the fighting is on his world. As a result, he mostly fights with physical combat as well as his scientific expertise. However, he eventually discovers they work on magical creatures in Kim, Ron, and Jake's world.
• Foil: Rex and Lance. Both were sons of scientists raised in a military of a sort, both rely on technological enhancements to fight, both have problems with authority and have experienced the loss of home and family at a young age. However, their personalities and approach to combat are complete opposites. Rex is outwardly very excitable and emotional, prefers a straightforward approach to combat, yet actually has a good handle on his emotions (too much anger causes his Builds to fall apart) and is in fact, quite intelligent, giving logical reasoning for a head-on assault of the Mutradi base, and exploiting the environment to defeat the commander. Meanwhile, Lance outwardly projects a calm, collected attitude and favors stealth to gather intelligence before committing to a plan of attack, but suffers from violent outbursts when something unexpected happens, and while well trained and highly skilled in combat, seems to lack creativity in his tactics.
• Genius Bruiser:
  • As per canon, Octus, aiding in the construction of the team's portal generators and acting as one of the resident science experts. He is also capable of running down dozens of Mutradi soldiers single-handedly.
  • In addition to his extensive combat training, Zak has displayed advanced skills in science and engineering, being able to keep pace with Octus' explanation of how the rift gate works, and understanding the mechanics of the liquid metal Drakken aims to steal in Mission Possible.
• He's Back!: Villainous example in Episode 7. Argost has both a yeti body again (a clone body, by the way) and has his Anti-Kur powers back.
• Heroes Unlimited: At the end of the season, the team decides to start recruiting more members to counter the Cabal and their superior numbers.
• Hoist by His Own Petard:
  • How the Leviathan is ultimately defeated: Titan forces its mouth closed just as it's preparing to fire its Breath Weapon, which backfires and ends up disintegrating half its body.
  • The Cabal releases Argost's former body against the Avengers, but since it's mindless due to Argost's soul having been transferred back into a cloned Yeti body, Zak is able to take control of it without resistance.
• Hydra Problem: In Dawn of the Dragon, Lance, Rex, and Hayley face off against a hydra and encounter this problem. They resolve it the same way Hercules did, by dropping a rockslide on it.
• Irony:
  • While Ben knows Zak and Rex and Jake has met Kim and Ron at this point, the first meetings in the Sym-Bionic-Titan world are between Ben and Team Possible, Jake with Rex and Zak (while they both know Ben, neither have met the other), preventing any quick reunions.
  • Invoked by Chang, who uses the necromancy amulet to summon the ghosts of the Huntsclan, making a group that was formed to eliminate all magical creatures the minions of a being working to eliminate humanity.
• It's Personal: Rex has even more of a grudge against Van Kleiss here than in canon. This is due to his restored memories revealing that the man was responsible for the death of his parents when the Nanite Event occurred.
• Joke and Receive: Upon seeing Vlad's portrait (and getting some background from Danny), Ben comments that he'd expect the villain to own a cat. When Vlad faces them on a swivel chair with his cat in his arms the two burst out laughing.
• The Juggernaut: After reintegrating his cybernetics from the original series, Vilgax regains this status. To elaborate, in succession, he shrugs off blows from the team's heavy hitters (sans Titan), survives the vacuum of space unaided, falls from orbit and proceeds to continue fighting like nothing happened. Even after Danny and Ben's Combination Attack he was ready to keep going, only retreating because his forces were destroyed and he had already scanned Ilana's armor.
• Kraken and Leviathan: Dawn of the Dragons has the threat of the Dark Dragon unleashing the Leviathan, which was created by and then destroyed the Kim Possible/American Dragon world's version of Atlantis before being sealed away, and it's considered to be more dangerous than all the other thirteen greatest threats to the magical world, the Dark Dragon included, combined. Even the Huntsclan, which was dedicated to destroying all magical creatures everywhere, didn't want to mess with it. Once freed, it's revealed to be a massive serpent.
• Lampshade Hanging: Argost notes how the idea of various kinds of supervillains teaming up sounds like something out of television.
• Leeroy Jenkins: Justified. When the groups attack the Mutradi warp stations, most opt for a head-on assault, noting that with the number of soldiers each one contains, stealth would be extremely difficult and time-consuming. Since they are on a time limit a frontal assault is more practical, more so by the fact that each pair contains a One-Man Army or Person of Mass Destruction.
• Legion of Doom: While the heroes are unaware of it until Clash of Titans, Modula has responded to the formation of the Avengers by forging an alliance with the various team members' respective Big Bads, known as the Cabal. And it later turns out that while the Big Bads are the joint leaders of the group, the organization as a whole has a hundred members composed of other antagonists from their respective universes.
• Let's You and Him Fight:
  • Ben's first encounter with Kim and Ron devolves into this owing to his brusque attitude and the latter two mistaking him for one of the Mutradi.
  • Ben, Kim, and Ron have a subsequent encounter with Danny where he attacks them assuming they're Mutradi agents.
  • A villainous example — as shown in Clash of Titans, the first meeting of the Cabal members led to them fighting due to their clashing egos, until Modula broke it up.
• MacGuffin Guardian: The five keys that unlock the Leviathan's prison are hidden in different parts of the world, and are each protected by a legendary creature — the Mother Phoenix in China, the Quetzalcoatl in Mexico, the Yowie-Yahoo in Australia, the King Hydra in Greece, and the Sphinx in Egypt.
• Multiversal Conqueror: After the Avengers are defeated, Modula and the Cabal plan to conquer the Multiverse as a whole.
• No Plans, No Prototype, No Backup: The Cabal are able to create their own version of Octus, but for various reasons they can only create a single prototype because certain details of the construction are virtually impossible to replicate.
• Non Sequitur, *Thud*: In Ghost Busting, after Upchuck defeats the Lunch Lady by devouring her, meat form and all, he then spits her back out and sends her flying, resulting in this:
  Lunch Lady: (Dazed and has chicken legs circling her head) Now remember...you're a growing boy. (Keels over)
• Now You Tell Me: In "Dawn of the Dragon", when Jake mentions that Chang can't be helping the Dark Dragon as she was arrested following the time the Dark Dragon possessed Ron, Fu Dog pipes up and says he meant to tell him that Chang had escaped from prison. When the Avengers give him all a look, Fu Dog defensively cries it wasn't his fault cause Jake had been dimension hopping and he didn't have a chance to mention it to him.
• Odd Friendship: Zak, a human reincarnation of a cryptid with powerful mystical abilities from a family of cryptozoologists, and Octus, a multi-purpose robot less than a year old created by an alien race, seem to get along incredibly well, frequently partnering up on missions and enjoy each others company during their downtime, owing to their joint role as The Smart Guy on the team.
• Oh, Crap!: The Avengers' reaction when they deduce that their enemies are working together. And again when they find out it's far more than just their respective archenemies.
• O.O.C. Is Serious Business:
  • Ben and Rex are the two most carefree members of the team, but when confronted by Vilgax and Van Kleiss, respectfully, they become deadly serious.
  • Jake takes note on how Sara and Kara are noticeably scared before they reveal that the Dark Dragon is planning on freeing the Leviathan.
• Outside-Context Problem: From Modula's point of view, a ragtag group of unknown heroes not only thwarts his invasion (though he planned for that possibility), they also ally with his greatest threat, breach his planet's defenses, take out all his superweapons, and force him to flee. The crux of the next story is him learning everything he can about his new enemies to avert this trope.
• Pent-Up Power Peril: Titan defeats the Leviathan by holding its mouth shut so that its Breath Weapon cannot escape, building up to such a degree that it blows the Leviathan apart.
• Ragtag Bunch of Misfits: The team gets along well enough, but they have trouble coordinating in their early missions together; it took until the end of their second mission to officially 'designate' Danny as the team leader.
• Really 700 Years Old: Vilgax states that he's been conquering worlds and enslaving civilizations for thousands of years.
• Recursive Fanfiction: For the Danny Phantom and Kim Possible aspects of the story, the author draws on the Facing the Future Series and The More Things Change Series, respectfully.
• Red Oni, Blue Oni: The dynamic between Rex and Lance. The former is red, opting for a straightforward attack on the Mutradi forces and clearly looks forward to the resulting fight, while Lance acts as the blue, preferring to scope out the base and plan, and remains focused throughout the assault.
• Rooftop Confrontation: Zak and Argost duel atop the roof of Weird World in Episode 7.
• Running Gag: In the end of almost every story, one of the Avengers asks: "Should we go after [bad guy]?" Then somebody else say "No" and give a reason for that. Of course, later it bites the Avengers in the ass.
• Seen It All:
  • While most of the heroes express confusion at being transported to Sherman, Ben deduces he's in another universe almost immediately and only shows mild annoyance over the fact. When faced with the Mutradi fleet, he nonchalantly notes how similar alien invasion fleets look after you've seen them more than once.
  • By Dawn of the Dragons, the entire team seems to be moving toward this, with Rex noting a year ago fighting an army of zombie dragons would have gotten a much bigger reaction from him. In the next chapter, learning the Dark Dragon's goals of exterminating humanity and dominating the magical world gets a "yeah, figured" from him, much to Haley's shock, causing Rex to respond that when you've seen what the Avengers have, the villain Take Over the World shtick gets old real fast.
• Sequel Hook: The first season ends with the Cabal still active, the Avengers planning to recruit allies from their respective dimensions, and the mysterious leader of G3 stating he will reveal himself in the future.
• Ship Tease: Several times throughout the series between Lance and Ilana.
• Shipper on Deck:
  • Upon meeting Sam, Kim remarks that she and Danny complement each other quite well.
  • Kim also playfully teases Ilana by bringing up her obvious crush on Lance.
• Shout-Out:
  • Considering the name, it's obvious where the fic takes inspiration from.
    • Clockwork and Professor Paradox even discussed about the group's name, revealing that there's another team named "The Avengers". Interestingly, Professor Paradox throws in that the Multi-verse Avengers might have coined that term first.
  • At one point Ron makes a Game of Thrones reference.
  • The Yowie Yahoo exists on Jake, Kim, and Ron's world.
  • The Leviathan from Dawn of the Dragons is specifically based on the one from Yu-Gi-Oh!.
  • In Mission Possible many heroes said that they saw the movie with a robot made of liquid metal.
  • In a direct one to Hercules, Lance, Rex, and Hayley fight a hydra in the exact same way as Herc, complete with Fu Dog shouting:
  "WILL YOU FORGET THE HEAD SLICING THING?!"
• Simple Solution Won't Work: After the first fight against Goliath goes poorly, Rex suggests that Ben uses Upgrade to enhance Titan to even the playing field. Besides the fact that it would be adding another mind to Titan, making the giant harder to control, it's pointed out that even if it works, Albedo could just use Negative Upgrade to enhance Goliath in turn.
• Situational Sword: Zak's powers rarely come into play, owing to the fact that they only affect cryptids. A Nightmare at Weird World shows that when they do come into play it turns any encounter with enemy cryptids into a borderline Curb-Stomp Battle, with even the "battle" part being optional since he can simply get them to flee the battlefield, as seen when he drove off a small group giving the rest of the team trouble. In Dawn of the Dragons, it's discovered that it also works on magical creatures from Jake, Ron, and Kim's world, as he is able to disrupt the Dark Dragon's mind control spell on the Sphynx and the other guardians of the keys.
• The Smart Guy: A role on the team shared by Octus and Zak.
• Social Darwinist: Vilgax admits to Ilana that he's a monster, but he sees his actions as basically his divine right to do so because he's strong and the weak deserve to die. He even compares it to a human crushing an ant, it's just something he does.
• Spanner in the Works: Rufus frequently plays this role, being small enough that most villains don't notice him sneak by (either on people or around them). This lets him derail several plans by virtue of snatching the occasional MacGuffin under their noses or messing with whatever machinery is being used.
• Sufficiently Advanced Alien: Albedo is a Galvan, a species whose hat is super intelligence that makes them the greatest inventors in the Ben 10 universe. Yet even he can't fully understand how the Galalunan technology behind Titan works.
• Teeth-Clenched Teamwork: Baron and Shego despise each other, which limits their effectiveness as part of Goliath.
• Took a Level in Badass:
  • Villainous Example. Since his last canon appearance, Drakken has gained greater mastery over his plant powers, displaying the ability to grow prehensile tentacles similar to Doctor Octopus, allowing him to actually fight directly against Kim. He also displays more general competence as a planner, as outlined in Crazy-Prepared above.
  • Played with regarding Vilgax, as he's not so much gaining, but rather 'regaining' lost levels. In his appearance in Episode 5, he has restored his cybernetic enhancements from the original series while retaining his sword from Ben 10: Alien Force. The result is terrifyingly effective, with it requiring most of the team to push him back and a Combination Attack from both Danny and Ben, two of the Avenger's strongest members, to actually defeat him.
  • Zak ends up taking the Fang from Argost and wielding it in tandem with the Claw. In Dawn of the Dragons, he discovers that if he hits a target with both weapons at the same time and location, the anti-matter/matter reaction produces localized but devastating effects.
  • Illana is trying to do this as of Clash of Titans, having gotten sick of being useless in a fight outside her armor.
• Unspoken Plan Guarantee: Drakken succeeds in his latest scheme (upgrading his remaining weaponized toys from "So The Drama" and giving them a massive upgrade) partly because he doesn't tell anyone, even Shego, what it is so that the heroes are playing catch-up.
• The War Has Just Begun: Modula promises the Avengers this during the climax of Clash of Titans, noting that even if the heroes win this fight, there's more to come. Danny acknowledges that he was right about this at the end of the story.
• Wham Line: The ending of Clash of Titans and Season 1 features Solomon talking with his unseen leader about the events that transpired. It's here that the G3 leader reveals that, while the design of Novek is altered from the base, it's still recognizably his, revealing that he created Octus.
• What Measure Is a Non-Human?: Discussed between Illana and Octus after the confrontation with the Cabal's Titan, as Illana wonders if they could try and redeem Novex to stop the Cabal from using their Titan again and Octus confirms that wouldn't be possible as Novex was deliberately designed to be incapable of experiencing emotion that might inspire it to turn on its current masters.
• Whole-Plot Reference:
  • The first half of the prologue is basically a retake of both The Avengers (2012) and Justice League: War, with the Mutradi standing in for both the Chitauri and Parademons.
  • Follow the Leader likewise has a similar setup and resolution as the Young Justice (2010) episode "Drop Zone".
• Wizard Duel: One occurs during the battle in Atlantis in Dawn of the Dragons, between Max and the summoned ghost of Atlantis' archmage.
• The Worf Effect: The Cabal, especially Goliath, easily overwhelm the Avengers in their first major fight. By the second, the team has managed to figure out how to turn the tables.
• Worf Had the Flu:
  • In War of the Worlds, Vilgax pretty easily has his fleet wipe out Galaluna's defenses, but it's noted that the planet is still recovering from the previous Mutradi invasion and they're nowhere near their full strength just yet.
  • Rex initially fares poorly against Van Kleiss, with his anger making him sloppier and easier to predict. Once Ben arrives and he calms down, the two easily gain the upper hand in the fight.
  • It's made clear that the Dark Dragon underestimated Kim and Ron in their last fight, and wasn't using his full strength against them as a result.
  • This is also the reason for how Goliath is defeated. Baron and Shego were arguing so much that Goliath was unable to operate at full efficiency to the point of falling apart.
• Xanatos Gambit: Modula's plan in the first story, with him even saying that part of him was hoping the initial attack would fail. If the initial invasion succeeded, he'd have destroyed Titan and Earth would be at his mercy. If the attack was repelled somehow, which is what ended up happening? He secretly had larger rift gate generators sent through to other parts of Earth, and with the confirmation that they can now make rift gates that stay open as long as they desire, they could now send the entire Mutradi fleet through to Earth's orbit.
• Yin-Yang Bomb: Zak takes the Fang from Argost during their battle at Weird World, and in Dawn of the Dragons, he discovers that if it and its positive matter counterpart the Claw hit the same spot on an enemy at the same time the anti-matter/matter reaction produces unpredictable effects on the target, a miniature version of the weirdness produced in previous Saturday/Monday interacts. The first time it happens, the zombie dragon in question explodes.
• You Can't Thwart Stage One:
  • In Mission Possible, Drakken manages to successfully upgrade his reactivated toys from So the Drama before the heroes can even figure out his plan.
  • In Dawn of the Dragons, the heroes are unable to stop the Dark Dragon from freeing the Leviathan.

Season 2

• Ability Mixing: In Chapter 4 of Night of the Beyond, the Cabal's leaders combine the Infi-Map's powers with Dagon's energy to allow them to breach the defenses that Charmcaster has put up over Legerdomain. Then in Chapter 6, the Cabal's magical experts combine their different abilities in order to channel a control spell through Charmcaster in order to impose it on the reforming Dagon.
• Adaptation Expansion: When Breach returns, her backstory is discussed in detail, which was never covered in canon.
• All Your Base Are Belong to Us:
  • One of the attacks by the elemental monsters in Night of the Beyond is an assault on the Avengers mansion.
  • Later in the same story, the Cabal assault and seize control of Legerdomain.
  • Forces of Nature opens with Vortex and Undergrowth attacking the Guys in White HQ.
  • In A Ghost in the Machine, Technus takes control of Plumbers HQ in Ben's world as part of the Cabal's latest plan.
• Ape Shall Not Kill Ape: Averted. When it's questioned by Drakken if Argost is upset by fighting the ghostly Yetis of the Far Frozen during the Cabal's assault, Argost replies that not only do humans regularly slaughter each other without batting an eye, he's also killed one of his own kind before^note referring to the cryptid who had known him before he donned his human disguise, so this is nothing new to him.
• Avengers Assemble: As discussed at the end of the previous season, the Avengers start recruiting more of their allies to join the team.
• Big Damn Heroes: Breach makes their triumphant return by rescuing Zak from the water monster in Chapter 2 of Night of the Beyond.
• Big "NO!": Two by defeated villains at the climax of Night of the Beyond: first by Nocturne as he's being sucked into the Fenton Thermos, and then by Dagon as his energy is drained.
• Big "WHAT?!":
  • Believe it or not, Max was actually stupefied by Box Ghost of all beings upon learning about the time he took Pandora's Box (or rather, his dimension's version of it). Tucker explains It's a Long Story and not to ask about it.
  • Vortex's reaction when Ben, as Feedback, manages to absorb a lightning attack from him.
• Bittersweet Ending: Night of the Beyond. Dagon is stopped once and for all but at the cost of Hex's life. Not only that, the Cabal still escaped, taking Ledgerdomain's Alpha Rune with them, and the consequences of Dagon's resurrection will spring up in the future. However, the Avengers gained new members and they all resolve to protect the Multiverse from the Cabal's machinations.
• The Bus Came Back: Breach, last seen in Deus Rex Machina in Season 1, returns in Chapter 2 of Night of the Beyond.
• Canon Welding: A few examples show up in Night of the Beyond:
  • The Saturdays were some of the humans turned into Esoterica by Dagon. Zak even suspects that it was at least part of what reawakened his Kur powers.
  • Part of why Max's second reincarnation went so nuts is that he ended up in Legerdomain due to one of his experiments, and the power boost went to his head even after he went home.
• Chekhov's Gun: In Night of the Beyond, the Cabal manage to steal the Alpha Rune from Charmcaster, which the end of Forces of Nature reveals is going to serve as a power source for their new master plan.
• Dude, Where's My Respect?: The Box Ghost is furious that he's the only evil ghost in the Ghost Zone who wasn't recruited by the Cabal.
• Dumbass Has a Point: Downplayed in that he's not much of an idiot anymore, but in Forces of Nature, even Drakken was surprised at how incompetent the Guys in White were when Vortex and Undergrowth attacked their base.
• Easily Forgiven: Subverted in Night of the Beyond, where the Avengers and their allies all agree that despite working with Hex to save Charmcaster, neither can be forgiven for their crimes and will have to be arrested afterwards. Hex's Heroic Sacrifice changes things for him though.
• Elemental Absorption: The monsters in Night of the Beyond can absorb the element that they're made of from around themselves to repair damage and increase their size.
• Elemental Embodiment: In Night of the Beyond, monsters formed from rock, water, air, ice, and fire manifest to attack the Avengers as they're recruiting their allies to deal with the new magical threat.
• Elemental Rock-Paper-Scissors: The elemental monsters that attack the Avengers are defeated by taking advantage of their respective elements' natural weaknesses.
• Enemy Mine:
  • In Night of the Beyond, in retaliation for not being recruited by the Cabal like the majority of Danny's Rogues Gallery, the Box Ghost goes to the Avengers to warn them of their activities. Of course, he's not crazy enough to fight the Cabal, knowing he'd be in over his head.
  • Also in Night of the Beyond, after learning that Charmcaster is alive, Hex agrees to help the Avengers stop the Cabal's plans in Legerdomain in order to save her (and get his revenge on Addwaitya in the process).
• Evil Is Not a Toy:
  • In Night of the Beyond, Frostbite lampshades that Vlad has a tendency to try to harness powerful forces and beings only for the attempt to blow up in his face, and so rejects his Enemy Mine offer to deal with Dagon.
  • This is later lampshaded by Dagon himself in his fight with Max and Titan, saying that the Cabal is merely mortal, and he'll have his revenge when they eventually slip up and he breaks free from his leash.
  • Vlad lampshades in Forces of Nature about his past attempt to do this with Vortex, which is why he merely manipulated them and Undergrowth into attacking the Guys in White on their own instead of working with the Cabal, since he knows that they hate humans and would never go for it.
• Exactly What I Aimed At: When Hex and Addwaitya activate their piece of the Nightmare's Totem, nothing seems to happen to the squad of heroes confronting them, prompting Kim to ask if there was a delay reaction to it. Hex then reveals that the target of that spell wasn't the Avengers...but every human within a ten mile radius, turning them into Esoterica.
• Feed It with Fire: When the Far Frozen try to use their ice powers on the ice monster in Night of the Beyond, all they do is make it more powerful.
• Fighting a Shadow: Octus makes note that any physical damage done to Dagon is pointless because his true nature as an Energy Being. Dagon itself confirms this, and backs it up by constantly regenerating. The only thing that actually manages to damage him during that fight is Breach redirecting one of his attacks back at him.
• For the Evulz: In Night of the Beyond, when Illana wonders what reason the Cabal could have for being behind instances of Hate Plague, Ron reasons that it could be because they're bad guys. Danny comments that they may be evil, but everything they do is for a purpose.
• Elemental Embodiment: In Night of the Beyond, the Avengers deal with monsters made of earth, water, air, fire, and ice.
• Fusion Dance: In the climax of Forces of Nature, Vortex and Undergrowth fuse into one entity thanks to Van Kleiss using an energy equivalent of his mutating nanites to turn them into an EVO.
• Hate Plague: Night of the Beyond opens with simultaneous riots breaking out in Magus Bazaar, Amity Park and Bellwood, due to the residents being magically induced to see everyone around them as monsters (or Huntsmen in the case of the Bazaar's inhabitants) and viciously attacking them in panic. This is actually caused by traces of Dagon's essence within them which were triggered by the Cabal when they extracted it.
• Godzilla Threshold: Invoked with Titan in Forces of Nature when Valerie sees it for the first time, and wonders why the Avengers hadn't pulled it out before. Ben explicitly calls it a weapon of last resort, and Danny adds that he doesn't want them to become too dependent on it so that they can keep growing stronger as a team.
• Heroic Sacrifice: In the climax of Night of the Beyond, in order to stop Dagon from coming back again, or the Cabal trying to bring him back again, Hex has himself infused with Dagon's energy and sent to the Unworld, knowing that he'll die, but that Dagon will be either destroyed or trapped in the Unworld forever, with Clockwork later confirming the former.
• Hijacking Cthulhu: In Night of the Beyond, The Cabal is harnessing Dagon's power as he tries to reform, and combines it with the Infi-Map to gain access to Legerdomain so that they may take advantage of his resurrection and turn him into their Living Weapon.
• Hold the Line: In the climactic battle of Night of the Beyond, Titan and Max take on Dagon to keep his attention away from the rest of the heroes who are trying to reach the Cabal's machinery. Predictably, they lose the fight, but Dagon's supreme arrogance prevents him from noticing Ben-as-Upgrade taking control of the machines that can absorb its essence and draining it once more.
• How the Mighty Have Fallen: Modula says this in reference to Charmcaster after taking her prisoner.
• Hurl It into the Sun: Suggested with Undergrowth, but even if Breach teleported his entire upper body he'd just regenerate from the roots, and he's too intertwined to get out via her portals without causing serious damage to the town.
• I Choose to Stay: After the battle with Dagon, Fiskerton, Komodo, and Zon choose to remain and become official members of the team, with Doc and Drew approving.
• Killed Off for Real:
  • In Night of the Beyond, Hex stabs and kills Addwaitya, finally avenging his brother.
  • Later, Hex makes a Heroic Sacrifice that successfully destroys Dagon for good.
• Lame Pun Reaction: After Kim and Jake's group manage to defeat the air elemental, Fu Dog makes several jokes about it, which just receive groans from the group, with Kim giving a "No. Just… No" Reaction to one in particular.
• Locked Out of the Loop: In Night of the Beyond, Hex was unaware that Charmcaster was alive until Gwen tells him.
• My God, What Have I Done?: Everyone affected by the Hate Plague has this reaction after getting free of it and realizing they were attacking their friends and neighbors. One Bellwood police officer actually says the trope name word for word.
• No-Holds-Barred Beatdown: Charmcaster suffers one when the Cabal comes calling to Legerdomain, with each Big Bad pitching in to lay on the pain even after she's beaten and trying to get away.
• Not Me This Time: In Night of the Beyond, the Cabal isn't actually causing the Hate Plague incidents, that's Dagon's essence, but they're still taking advantage of them for their own plans.
• Oh, Crap!: Ben's reaction in Night of the Beyond when he realizes that the energy being used by the Cabal's mystics is Dagon's essence.
• The Only One Allowed to Defeat You:
  • Averted. Hex declares he doesn't care if Addwaitya is killed by his own hands or the Avengers, just so long as he meets his end.
  • Inverted when Breach defeats Van Kleiss but refuses to finishes him off, stating that only Rex has that right.
• O.O.C. Is Serious Business: Gwen is very confused as to why Hex would be working with Addwaitya as part of the Cabal, considering what the latter did to his family. It's later revealed he was just biding his time until Addwaitya inevitably betrayed the Cabal so that Hex would have an excuse to kill him.
• Outside-Context Problem: Whatever's causing the attacks in Night of the Beyond doesn't appear to be from any of the Avengers' respective universes. It ultimately turns out to be the harnessed energy of Dagon, making it an OCP to all their universes except Ben and Zak's.
• Pass the Popcorn: While watching the Avengers fight the Esoterica, Panderus happily notes that he should have brought some popcorn.
• Place of Power: In Night of the Beyond, Legerdomain, as in canon, significantly boosts the power of magical beings that enter it. Even magics from other worlds, like the Dark Dragon and Argost's Anti-Kur powers, get a boost, the latter becoming powerful enough to take control of Charmcaster's golems.
• Power High: According to Max, his second incarnation, Myrddin Wyllt, accidentally transported himself to Ledgerdomain, which enhanced his magic to the point that he felt he could do anything. Unfortunately, after he left Ledgerdomain, the power boost vanished and he ended up with power-addiction which soon led to him going insane.
• Powered by a Forsaken Child: In Night of the Beyond, the Cabal uses Charmcaster as the focus for the spell to reform Dagon under their control.
• Pragmatic Villainy: While Operatives O and K hate ghosts and Phantom just as much as most of the Guys in White personnel, even after he saved the world, in Forces of Nature they point out that Danny's aforementioned saving of the world has granted him a lot of public support, and if they make a move against him and his allies and don't succeed, it could result in them losing their funding, or even being shut down. Agent Alpha disregards their worries as something for the P.R. department, but they don't get a chance to try before Vortex and Undergrowth show up.
• Pulling Themselves Together: Night of the Beyond reveals that the crisis is being caused by Dagon's essence trying to pull itself back together after Ben scattered it using Ascalon, with the Cabal attempting to harness that power for their own.
• Reforged into a Minion: In Night of the Beyond, the Cabal manages to harness Dagon's energy and turn a number of captive humans, as well as magical creatures from Jake's world, into Esoterica. And it turns out that their master plan in the story is to place a control spell on the reforming Dagon in order to make him serve them.
• The Reveal:
  • It turns out that during the time Ben and his team were fighting Dagon and Vilgax, the Saturdays were among the people transformed into Esoterica, with Fiskerton, Komono, and Zon even forced to defend themselves during the ordeal. Zak theorizes that Dagon's essence was what ended up reviving the residue Kur energy inside him.
  • In season 1, Van Kleiss revealed that he no longer needs a constant supply of nanites to survive, but the details were never revealed. In Forces of Nature, it's revealed that, with the help of the Cabal, he's modified his gauntlet so that he can sustain himself by means of direct Energy Absorption. He also modified the Anti-Ecto Converter with the same energy, turning Vortex and Undergrowth into a single Ghost/EVO hybrid in the climax.
• Shout-Out:
  • Regarding the magic causing the strange incidents in Night of the Beyond, Max says that he felt a disturbance in the Force. Jake immediately calls him out on quoting movies at a time like this.
  • The elemental monsters that attack the Avengers are based on the Elementals from Spider-Man: Far From Home, albeit with Ice added to the four from that film. Except unlike Mysterio's, they're real.
  • Breach's new outfit is stated to take heavy cues from Elizabeth Comstock from Bioshock Infinite.
• Shut Up, Hannibal!:
  • During the fight in the Naga city in Night of the Beyond, Rani Nagi is ranting about killing the Avengers when in response Breach redirects several attacks by the Esoterica into her, knocking her off a ledge.
    Breach: You talk too much. You know that, right?
  • Max interrupts Dagon's rant about the inferiority of mortals by pointing out that mortals have defeated him numerous times.
• Tempting Fate: In Night of the Beyond, a bored Rex says that nothing is going on right now. Newton promptly arrives with his Super-Speed and states that multiple explosions are going off outside the mansion.
• This Explains So Much: Upon learning that Gwen is of Anodite heritage, Hex notes this this explains why she was able to master magic so quickly.
• Underestimating Badassery:
  • In Night of the Beyond, while fighting the Cabal, Ron goes up against Modula, who doesn't think much of him. Much like when he fought Warhok and Warmonga, Ron pretty much curb-stomps him, though he was boosted by Ledgerdomain at the time.
  • In Forces of Nature, the Master's Blasters think that they can beat Vortex and Undergrowth again easily. Unfortunately for them, even if it's not implied that Vlad had the two sandbagging to build up the Blasters' rep and tear down Danny's, their Villain Team-Up lets them defeat the team easily.
• Unfinished, Untested, Used Anyway: In Forces of Nature, when Undergrowth and Vortex attack the Guys in White's headquarters, Agent Alpha decided to have them use their experimental Anti-Ecto Converter. Deconstructed in that it doesn't work, though the fact that the Cabal sabotaged it in order to give the Avengers a surprise later (and to steal it) should be noted.
• Unwitting Pawn: In Forces of Nature, Vlad leaks information to Undergrowth and Vortex which leads them to teaming up and attacking Amity Park, distracting the Avengers from the Cabal's newest plan.
• Ungrateful Bastard: While at least one scientist recognizes how Danny Phantom and his allies helped save the world, the majority of the Guys in White still hate him and all ghosts. Agent Alpha in particular is infuriated by how people are supporting Phantom over them when he and his allies are unregistered, and starts Forces of Nature planning an attack on him.
• Villain Team-Up: Vortex and Undergrowth have their own alliance which is distinctly separate from the Cabal, which Vlad knows they would never join due to their hatred of humans.
• With Great Power Comes Great Insanity: Night of the Beyond reveals that part of the reason why Max’s second reincarnation went insane was because he accidentally ended up in Legerdomain, and the power boost went to his head even after he returned and lost it.
• Year Inside, Hour Outside: While it's only been a few months for the Avengers since they last saw Breach, for her it's been five years due to traveling with Paradox.
• You Can't Thwart Stage One: In Night of the Beyond, the Hate Plague and the elemental monsters' attack are evidently Phase 1 of the Cabal's new plan. By the time the Avengers even realize they're involved, they're already simultaneously carrying out Phases 2 and 3. By the time that the heroes take down the Esoterica, the Cabal leaders have already made it to Legerdomain using the Infi-Map and Dagon's power. And by the time the Avengers manage to catch up to them there, they've managed to resurrect Dagon.
• You Have GOT to Be Kidding Me!:
  • Sam's reaction when the Box Ghost shows up in the Avengers mansion.
  • Jake's reaction to Undergrowth barely being slown down by having a building dropped on him.
