It's a crossover between some of the best action cartoons of the early 2000's. There was bound to be plenty of these.
Season 1
- Avenger's of the Multiverse:
- The first time the heroes (most of them) assemble in taking on the Mutradi.
- Episode 1, A Home Away From Homes:
- Danny No-Sell's the Mutradi phantoms attempts at possession, and quickly realizes how to free the others.
- Episode 2, Follow The Leader:
- Episode 3, Ghost Busting:
- Episode 4, Mission Possible:
- Drakken actually comes close to succeeding with a plan, and he's become competent enough with his Green Thumb powers to give Kim a hard time in a fight.
- Episode 5, War of the Worlds:
- Vilgax is back and he's back to the powerhouse he was back in the original series. He single-handedly drives the Avengers to the brink until Danny and Ben uses their sound-based powers to put him down but even that was temporary.
- Episode 6, Deus Rex Machina:
- Van Kleiss makes an E.V.O. out of the remains of several Mutradi monster remains, which Titan is forced to battle. Mid-fight, Octus figures out a way to disable the nanites in the beast, instantly netting them a win and showing off his merits as a Genius Bruiser.
- After calming Rex down, Ben teams up with him against Van Kleiss, and the two display excellent teamwork, easily holding the upper hand the entire time against the E.V.O. Rath's comment on them being the best team in a fight appear well founded.
- Episode 7, A Nightmare at Weird World:
- Despite being Brainwashed and Crazy, Doc's dealing with Rex is impressive.
- Argost and Zak have a Rooftop Confrontation, trading blows with hand-to-hand, Claw vs Fang and summoning cryptids for help on both sides. Then Zak snatches the Fang from the yeti and starts Dual Wielding the grapple staffs.
- After sending Argost packing, the Avengers and the Saturdays decide to destroy Weird World. It's satisfying for them and for us, the audience, to finally see that awful place torn down to pieces.
- Episode 8, Dawn of the Dragons:
- Zak plays a key factor in stopping the Guardians when he takes control of them, showing that his Kur power aren't just limited to Cryptids.
- Titan vs the Leviathan. Titan WON.
- Danny's solution to the zombie problem:Chang: There is no mortal weapon or magical means to destroy that amulet!
Danny: No magic, huh? Good thing I don't have any.
(Blasts the amulet into kingdom come)
Chang: NOOOO! How...how did you...?
Danny: An amulet that control the dead, ghost powers, you do the math.
- Episode 9, Clash of Titans:
- The Evil vs. Evil opening, where all the Big Bads duke it out in a vicious throwdown. Highlights include Drakken and Van Kleiss ganging up on Munya and Vilgax and Dark Dragon fighting each other.
- Goliath is even more powerful than Titan. If it wasn't for Shego's unwillingness to kill hampering them, the Avengers wouldn't have survived until G3's rescue, also an awesome moment.
- After a few false starts, the Avengers come up with a viable plan to defeat Goliath; have Ben scan the energy creature that had drained Octus in canon, use the Omnitrix to turn into a copy of it, and drain Novex to the point of shutdown.
- Titan manages to defeat the much larger Goliath by taking advantage of the disagreements between Shego, Baron, and Novex, as well as taking inspiration from the fighting styles of the other Avengers.
- Rex using his knowledge of Ben to defeat Albedo, not just countering his alien forms' skills, but taunting the Galvan until he slips up and gives Rex an opening to knock him out.
- Jake and Solomon tag-teaming Skulker, eventually defeating him by hacking his suit.
- Kim, Ron, and Danny taking on Modula, getting a win on him even before everyone else shows up.
- Danny deciding to expand the Avengers to fight the Cabal.
Season 2
- Night of the Beyond:
- The Avengers managing to subdue the Hate Plague affected civilians without any fatalities.
- The defeats of each one of the elemental monsters.
- Breach pulling a Big Damn Heroes moment, rescuing Zak from the water monster by opening a large portal underneath it and sending it to beneath the Earth's mantle, completely evaporating it.
- The Cabal's plan is to harness the powers of Dagon, and start by turning a number of humans and magical creatures from Jake's world into Esoterica.
- When fighting the Esoterica, Breach actually creates a pocket dimension. Though it clearly strains her, it's still an impressive feat.
- Frostbite calling Vlad out for all his past Evil Is Not a Toy schemes and rejecting his offer.
- Although they're ultimately defeated by the Cabal leadership, the Far Frozen Yetis do not back down in their duty to protect the Infi-Map.
- Charmcaster fighting the Cabal leadership when they invade Legerdomain. While she ultimately loses, she lasts considerably longer than they expected her to.
- The magical Avengers and Breach combining their powers with Hex to open a portal to Legerdomain.
- The Avengers and their allies fighting a small army of Lucubra controlled by Argost in Legerdomain.
- In a villainous example, the Cabal succeeds in resurrecting Dagon.
- Titan and Max fighting Dagon to buy time for the other heroes to stop the Cabal.
- Breach absolutely pummels Van Kleiss, making it clear that he's only still alive because Rex is the one who should determine his fate.
- Argost and Zak taking advantage of Legerdomain's boost to form giant constructs out of their Kur powers to fight each other.
- Like when the fought Alpha, Ben combines Upgrade with Rex's nanites again, allowing them to quickly turn the tables on Vilgax.
- Hex stabbing and killing Addwaitya, and thus finally avenging his brother.
- Rufus tapping into his portion of the Mystical Monkey Power to lay the smackdown on the Cabal's cronies.
- Once Ben uses the Cabal's machine to heal the spatial rifts, Hex lets himself be sent to the Unworld with Dagon inside of him to stop Dagon for good, an action with posthumously earns him the title "Avenger".
- Forces of Nature:
- A villainous example — Undergrowth and Vortex test out their Villain Team-Up by attacking the Guys in White headquarters and tearing through their defenses with minimal effort.
- Vlad, Drakken, and Van Kleiss were watching the attack without any of the parties involved being the wiser, even modifying the prototype Guys In White Anti-Ecto Converter to give the Avengers a future surprise...
- Another villain example, but Undergrowth shows that he's continued to adapt to the tactics of the heroes by using ecto-enhanced oak to resist Sam's Playing with Fire powers.
- Kim, Ron, Rufus, Zon, and Komodo taking the mind-controlled Masters Blasters out of commission.
- Breach dropping a building on Undergrowth. And to his credit, it barely slows him down.
- Ben turning into Feedback to absorb Vortex's attack and throw it back at him. And later, turning into Heatblast and blowing Vortex up from the inside.
- Van Kleiss revealing that not only can he survive without nanites now, but he can use a type of energy similar to the nanites to affect beings that can't be turned EVO normally, like ghosts. This is what he did to the Anti-Ecto Converter, causing Undergrowth and Vortex to do a Fusion Dance into a single being that can give Titan and Atomix together a hard time.
- Atomix and Titan working together to defeat the Undergrowth-Vortex fusion is quite impressive. Danny later gets confirmation from the Observants that the two villainous ghosts had their essences scattered so far across the planet that it's unlikely that they'll show up again for a while.
