Let's face it, even after all those years the "Terminator meets Back to the Future" Fake Trailer is still the most awesome video they ever made. Watch it on YouTube and at any given time among the top comments there will be a request to expand it into a full movie. The video doesn't even have that many jokes, it's just So Cool, It's Awesome.
Thor delivers a pretty sick burn to Superman and Batman in his HISHE: "That may be true... but at least I have a father." To the point where both Batman and Superman admit it was sick.
Captain America pulls one off too when he points out that the Justice League movie's still in Development Hell, while the Avengers (At the time of the video) were gearing up for their venture. Even Batman and Superman admit that's a pretty good burn.
And to top it off, we have the Avengers et all reminding Sups and Bats about their box office income.
The DC duo gets back at one of them, by leaving Thor in the booth while they hide outside.
Which in turn leads to one for the Joker (and the film itself). In spite of Batman injuring him to the point of immobility, the Joker is still enough of a Magnificent Bastard to make sure the events of the movie still happened. So Batman ends up becoming a wanted criminal anyways.
After their take on both The Lord of the Rings and The Hobbit had the "use the eagles to solve everything" joke, "How The Desolation of Smaug Should Have Ended" defies it instead, with Bilbo chewing out Gandalf for trying to use it a third time.
"The Lego HISHE" continues right from where the Movie has ended. It's made for a tiniest fraction of the movie's budget, but looks just as AWESOME!
It also sees (Lego!) Superman single-handedly take out all of Lord Business' forces and hailed a as hero, rather than get taken out by a wad of gum in the movie (which Batman suggests must have been "Kryptonite gum").
Later in the video, Superman and Batman look outside to see an epic battle being waged between the Master Builders and the Lego Duplo aliens that popped up at the end of the movie.
Duplo Alien: We are here to destroy you! Emmet: (clobbering enemy in his Mini-Mecha) No, no you're not!
In How X-Men: Days of Future Past Should Have Ended, Quicksilver saving both Trask and Mystique so quickly, the only time he becomes visible at all occurs when he takes Mystique away to safety, then brings Xavier in to assure Trask of mutants' goodness. Later, Quicksilver unmasks Batman (who seems more protective about his secret identity than he does now) without him noticing.
The ''Age of Ultron'' teaser parody has Ultron quoting various Disney movies. Hearing him quote "A Whole New World" actually does sound cooler than the Avengers give him credit for, considering the words "shining, shimmering, splendid" fit Ultron's character surprisingly well.
And then Superman retgones the whole situation, preventing entire Ultron creation.
In How Avengers: Age of Ultron Should Have Ended – Part Two
Magneto shows up, casually curbstomps the Ultron army, and proceeds to claim Scarlet Witch and Quicksilver as his kids as well as state they're mutants.
Scarlet Witch stops Batman mid-catchphrase by making him afraid of bats.
The parts in How Revenge of the Sith Should Have Ended is awesome enough that one could wish it were actual canon. Such as the Jedi not holding the Idiot Ball while planning a coup against Palpatine, Anakin reporting Palpatine's confession to the Jedi Council, and the ending with Anakin and Padmé raising Luke and Leia.
After being apprehended by Han, Chewie and Finn, Captain Phasma secretly alerts an entire stormtrooper platoon to their current location. That's why she gets the platinum armour!
Also, Luke's Big Damn Heroes moment when he shows up just in the nick of time to kill Kylo Ren and save Han's life.
In the Alternate HISHE, Leia reveals that the Resistance has spent the last 30 years building their own Death Star, the Right Back Atcha. It destroys the Starkiller Base in one shot.
In the LEGO HISHE, Luke kicking Kylo Ren's ass after he's tracked down on his island. Then he proceeds to spank him with a Stormtrooper's baton (along with Anakin Skywalker's ghost appearing and siding with Luke after Ren begs for his help), then Luke drags him home to his parents using the Force.
Batman prepares his second Kryptonite grenade, aims at Superman, shoots, and Supes dodges.
Batman: What? How?! Superman: Because I'm "faster than a speeding bullet". I win! Batman:Oh shi-[Supes charges at him]
After Lex blows up the Senate, Superman simply says "Dang it!", goes back in time by spinning the earth backwards, takes the wheelchair hiding the bomb, and throws it up into the sky. Doing so even earns the cheers of the people who were there to protest him!
Superman is preparing for what he thinks is a Heroic Sacrifice which in the movie does kill him. But instead Batman picks up the kryptonite spear and kills Doomsday while he's still caught in Wonder Woman's lasso, with no heroes dying in the process. Topped off by the most badass use of HISHE Batman's catchphrase ever... to the tune of Leeroy Jenkins.
Batman: Alright chums, let's do this! BECAUSE!!![Superman and Lois stare in disbelief]I'M!!![draws gun and shoots a kryptonite gas grenade at Doomsday]BATMAAAAAAAAAAN!!![leaps forward and stabs Doomsday]
After being repeatedly mocked by the Avengers for its absence for years, the Justice League finally gathers at the Super Café.
Vision derails the plot right at the start by capturing Crossbones, asking "Why wouldn't I be here?"
The entire team minus Tony nailing how absurd and hypocritical making them sign the Sokovia Accords is, given how many more people would have died if they did nothing. Sam points out governments were quick to launch a nuke on Manhattan (in The Avengers), calls Tony out oncreating Ultron and Steve says that everyone will immediately sign on if they just change the name to "The Tony Accords". And General Ross agrees to it!
Spider-Man effortlessly webbing up all of Team Cap at the start of the airport fight.
Vision preventing Cap and Bucky from escaping by simply blowing up the jet itself, rather than the aircraft hangar.
Bucky fully admitting his complicity in the murder of Tony's parents, and saying he has no right to expect any forgiveness but is still sorry. This calms Tony down enough to cut Zemo out of the room he's hiding in, and bring him in.
And he goes even better in the "But This Is How It Really Should Have Ended" ending: When Zemo goes through the trigger phrases, he simply plugs his ears and goes "la la la la la!", resulting in the other heroes capturing him right there.
Enchantress kills Waller right at the start after she leaves that briefcase with everything she needs out in the open.
June similarly derails the whole story by making sure the statue Enchantress is trapped in remains intact, pointedly saying what a good archaeologist she is.
After Flagg discovers Harley's Explosive Leash has been disabled, Waller reminds him he still has a gun, so he just shoots her.
Deadshot not only simply shooting Waller as she's about to send them back to prison, but nailing her tablet with all the information on them before it even hits the ground.
Batman discovering the location of the Villain Pub by following the Squad there. Bet you never thought you'd see such an enticing cliffhanger ending in a series like this.
In Villain Pub – Boss Battle:
Batman actually gets into the Pub and single-handedly curb-stomps such villains as Predator, Loki, General Zod and more. Eventually, he takes out the Infinity Gauntlet from Thanos, prompting him to finally spring into action.
Points for Palpatine as well, who successfully captures Batman by overwhelming him with various female villains, then chaining him up in the wine cellar to be eaten by Jaws. Palpatine's also savvy enough to remove his utility belt when putting him in the trap, resulting in Batman being forced to accept help from Doctor Strange (2016) and beg for the Justice League's help for the next time he tries to assault the pub.
Obi-Wan utterly curb-stomping Darth Vader by using the Force to crush his metal legs, crush his life support system, and rip off his mask.
There's also R2 finally taking matters into his own hands and single-handedly blasting away all the invading Stormtroopers aboard Leia's ship, complete with an implied Take That! to those who complained about Rey in The Force Awakens:
In Harry Potter HISHE, Snape saves Harry and kills Voldemort during their last fight. Using a handgun. After that, he uses Time Turner which Hermione has had (and preserved, on Harry's inquiry), goes to the past, and kills Tom Riddle when the latter first meets Dumbledore, saving him and many people from the future Dark Lord, averting two wars. Hooray to Snape!
Jyn's mother takes out Krennic and all his men with a blaster as soon as he lands.
Rather than send his daughter into danger, Galen copies the Death Star plans onto a disc that he sends along with his message. And Saw makes sure Jyn doesn't leave it behind.
The whole team jumps into action to save Galen right before his death.
Their take on the ending: Everybody Lives, thanks to Chirrut turning his staff into a lightsaber and getting force powers, Bodhi throwing back the grenade, and K-2 downloading himself into another body and picking them all up just before the shockwave reaches them.
The video description states that the reason they made it that way was that Logan "already ends pretty beautifully."
In Kong: Skull Islandthey take full advantage of the film starring four Marvel Cinematic Universe actors, with Kong squashing Loki even easier than the Hulk, followed by Nick Fury telling him about the Kaiju Avenger Initiative while joined by Rhomann Dey and Captain Marvel.
The whole Wonder Woman, Supergirl and Batgirl scene works in two ways: First, it's a nice little celebration on how there's finally a good superheroine film, and second, shutting down Batman's catchphrase. Cathartic for fans who find Batman more irritating than funny.
Batman: Because I'm B-! Wonder Woman:IT'S NOT ALWAYS ABOUT YOU, BRUCE!
Even better: Supergirl and Batgirl decline to dig into the movie's very obvious problems. The film was good enough to not warrant nitpicking plot holes.
Palpatine's theory on who's going to die in Avengers: Infinity War: Every hero except Ant Man, who'll then go back in time through the Quantum Realm, where he'll meet up with Captain Marvel and they'll team up to set things right in the sequel. Odds are quite a few people said "Oh, that sounds cool" at the same time as Zod. Bonus points for actually being the closest to what happens in the movie.
During the climax of It, the Loser Gang realizes that with the ability to manifest anything they think of, they can call on the likes of Batman, the Ninja Turtles, King Kong, and the Ghostbusters to take care of Pennywise, even cutting him off from coming back in 27 years.
The Stinger for Black Panther has a new challenger for the throne: the true first successful black movie superhero, Blade!
This song became so well liked that it's gotten a callback in nearly everything that Cap's been involved in, usually used as a Take That! against him (as Batman, Superman, and/or others keep adding people or things that don't "yield" to his shield, such as the ice in which Cap was frozen in, the Winter Soldier and Spider-Man, who both caught the shield at one point, etc.).
HISHE marks its 10-year anniversary with a music video called Bat Blood, which is a parody of Taylor Swift's "Bad Blood" and has Batman rounding up several movie heroes, such as Doc Brown, Kiddo, Harry Potter, Baymax, Han Solo and Furiosa to fight Superman and the rest of the Justice League. Some people claim it is even better than the original one.
The complete version of their "Here Comes My Arrow" from their Guardians of the Galaxy Vol. 2 HISHE video, which is a parody of the song "Come A Little Bit Closer" by Jay and The Americans (the song that plays during Yondu, Rocket, and Groot's escape from the mutinying Ravagers).
The HISHE guys even managed to get an MOA in a video that wasn't even theirs. At the end of The Nostalgia Critic's review of Man of Steel, NC's version of Batman and Superman either wholeshare copy or homage the ending of How Superman Should Have Ended, only to awkwardly find the HISHE duo sitting at another table. And of course HISHE Batman's response to NC's Batman:
Batman doesn't have a beard!
As a testament to the awesomeness of this scene, Superman and Batman appear in the intro used in almost every Nostalgia Critic review released in 2014.
