When Gideon is defeated, $7 billion in coins falls all over the characters and their equipment. It appears to be painful.
Really Gets Around: Quite a few characters, but Ramona in particular. Wallace Wells is the homosexual version. Scott is actually worse than Ramona, though the movie only alludes to it.
Refrain from Assuming: In universe, Scott introduces the first song Sex Bob-omb plays as "Launchpad McQuack", to which Stephen Stills replies "Uh, that's not actually the name of the song..." (The song is actually called "We Are Sex Bob-omb"). (Of course, the lyrics don't contain the words "Launchpad McQuack", making one wonder where Scott got that name from).
An out-of-universe example, the second song Crash and the Boys play is NOT called "We Hate You, Please Die" - that song was actually cut from the movie, despite the announcing of it being left in. The song that plays in the movie after the announcement of that song is actually called "Last Song Kills Audience" - this can be found in a deleted scene on the DVD.
Scarf of Asskicking: Knives dons one for the final showdown. She even uses it to disarm Gideon, turning the tide of the battle.
Scary Shiny Glasses: You can see a digitized "X" in Gideon's glasses during the final fight, and it even shimmers when he adjusts them.
The Scottish Trope: Stacy refers to Envy as "She Who Shall Not Be Named" in reference to the trope's use in Harry Potter, while Wallace informs Other Scott that said woman's name is not to be used in the apartment.
Self-Fulfilling Prophecy: When Scott storms the Chaos Theatre for the second time, already knowing much of what will happen, he yells to Knives, telling her, "don't attack from behind!" What does Knives do just as Scott is finishing the sentence? She attacks Ramona, from behind.
Serial Escalation: The entire film. Parodied when an exasperated Scott blows up on Ramona and tells that when he dated Kim, he had to fight 96 guys and an 80-foot tall purple robot and "...I kicked him so hard, he saw the curvature of the Earth!"
Turns out, he wasn't being sarcastic.
Sheathe Your Sword: Nega-Scott, though it happens off-screen. It's foreshadowed that Scott should have no chance against him, but according to Scott, this trope happened, they talked, and made plans to go out for breakfast in a few days.
Shout-Out to Shakespeare: The creature summoned by Sex Bob-Omb against the Katayanagis was officially named the "Green-Eyed Monster," after the Shakespearean phrase to describe jealousy. Also notice that Scott's eyes are glowing green in this scene.
When Scott is staring at Ramona in the real world for the first time, and a low bassline is playing, the scene then shifts to when Scott is performing. Stephen replies "Scott! You played one note for that entire song!"
And again when Scott realizes he never broke up with Knives at the Rock It and she shows up in front of Ramona. It sounds like his heart is racing and he runs away. The beat is the host hitting the microphone.
Julie's profane rant at Scott in the Second Cup uses this, as well as a bar blocking potential lip reading. Becomes even more hilarious when Scott lampshades this and asks "How are you doing that with your mouth?" (even though Scott was able to do this himself in Scott Pilgrim vs. the Animation...).
Amp feedback in the scene before the Katayanagi Twins battle obscures Stephen's use of "cock" in the sentence "You know how I feel about girls cock-blocking the rock." The DVD trivia track reveals this was done to avoid an R rating.
Stalker with a Crush: All three points of the Love Triangle exhibit this trait - Knives is this with Scott (even while dating, though that could simply be her way of trying to bond with her boyfriend) at first, and then it is turned Up to Eleven after they break up. Scott stalks Ramona both prior to meeting her (partially in a sequence lampshaded with subtitles calling him out on it), and during their early courtship. Finally, Ramona admits that she was the equivalent of Knives in regards to Gideon and that she moved to Toronto to escape that mindset.
Wallace does this somewhat more literally, outright telling Scott that he's off to stalk Lucas because he's attracted to him.
Stealth Insult: Even after signing onto Gideon's contract, Kim flips him off very subtly, by using her middle finger to "rub under her eye."
Kim: We are Sex Bob-Omb. We are here to make money and sell out and stuff.
Young Neil: (After the Clash at Demonhead plays) Yeah, you should see them live, they are so much better live! Think about that one.
Sting: Kim does this sometimes with her drums (by miming shooting herself in the head and collapsing onto her drumset, no less) when Young Neil, Scott, or Stephen are acting particularly stupid.
The Stinger: Stay through the credits and watch the words "The End" come up...then watch Scott Pilgrim from the video game come in and punch the shit out of it! Doubles as a cross-promotional shout out.
Summon Magic: The aforementioned Demon Hipster Chicks, as well as the Green-Eyed Monster and the double-headed dragon summoned in the battle between Sex B-Bomb and the Katayanagi Twins through The Power of Rock.
Symbolic Blood: The coin drops pretty much become this by the end of the movie. At one point, someone on the verge of dying actually coughed up coins.
Although many conflate the movie with hipsterism, others consider it a Take That against hipsters, what with Gideon's "I'm cooler/better than you" villain rant, and Todd/Natalie explaining that "being a vegan just makes you better than everyone." Not to mention the final battle theme is titled "Death to All Hipsters". Of course, anyone who thinks it isn't possible to both be hipstery and be anti-hipster clearly doesn't understand hipsters.
Gideon and Sex Bob-Omb play a big part in a Take That against big stereotypical music labels that pump out music for the sake of money without caring about artistic integrity. Stephen signs the band to Gideon simply cause they're offered loads of cash and recognition, even though Gideon is pretty obviously a big Jerk Ass. Scott, knowing better, quits the band cause he doesn't want to sell out to him. The song Sex Bob-omb plays when Scott first enters the club is aptly titled "No Fun". When the first round of Scott's final battle with Gideon begins, Gideon demands Sex Bob-Omb to play a pretty cool but still largely generic tune while Kim, completely unmotivated, proclaims they're playing to sell out. Once Round 2 begins however, witnessing Scott finally gain his own self-respect and ultimately become the better man, the band finally comes to realize that there is more than just money and fame, and with their own freedom, they play the same song but this time taken Up to Eleven.
Take That, Us: Comeau can be heard telling someone "The comic book was better than the movie" when Scott enters the Chaos Theater the second time
That Came Out Wrong: When the issue of Knives' age comes up in front of Ramona, Scott's brain switches to an excuse wheel which settles between "Gotta pee." and "Who, her?". Scott subsequently mangles this to "I gotta pee on her."
The Dragon: Co-Dragons, literally. The last but one boss not counting Nega-Scott is a pair of Japanese twins who use synthesiser keyboards to summon twin dragons.
There Was a Door: Subverted. Todd knocks Scott through quite a few walls and looks through the resulting holes menacingly...and then proceeds to use the door to reach Scott anyways. By Offscreen Teleportation.
Scott vs. the Bonus Boss, Nega-Scott. Who turns out to be a pretty cool guy, so the drama wasn't necessary. Technically, Scott had to defeat all of the exes himself.
Roxy: "Give it up Ramona, this is a League Game!" Ramona: "Meaning?" Roxy: "Meaning that your precious Scott must defeat me with his own fists! ...Or possiblyhis feet!"
As the Exes grow more powerful, Scott needs a lot of help to deal with them- The Vegan Police strip Todd of his powers, Ramona tells him Roxy's secret weakness, and the rest of Sex Bob-Omb help him take out the Katayanagi Twins. Scott actually dies when he tries to take on Gideon himself the first time, and it's only with Knives' help he defeats Gideon the last time.
It seems that Scott needs help for every fight. Wallace assists in the first two by heckling/demoralizing Patel and setting up Lee's undoing (he even hands him the fatal skateboard).
Title Drop: According to the cast commentary on the DVD, a cut line had Scott saying "Yeah, I guess I'm just... Scott Pilgrim vs. the world" towards the end of the movie.
Took a Level in Badass: Scott gaining The Power of Self-Respect in Chaos Theatre Round 2 is the culmination of his Character Development. Suddenly he blazes through the crowd of mooks like a hot knife through butter all while his former band now with newly gained respect for him play the Theme Music Power-Up version of the crew's theme song.
Toronto: Openly shown as the setting of the film for once, as in the comic.
Unreliable Narrator: Many critics, cast members, and even creator Bryan Lee O'Malley have claimed that the film, to a certain degree, may be from Scott's point of view, explaining all the weird, video game stuff happening and why nobody seems to react to supernatural powers and people dying (because it didn't really happen.) O'Malley even told Jason Schwartzmann not to worry about crafting a realistic character, but instead playing Scott's Flanderized version of Gideon.
The Katayanagi Twins prefer to let their music speak for them. Apparently, the casting office forgot to write "identical mid-twenties attractive English-speaking Japanese twins" into the casting call.
Lynette, The Clash at Demonhead's bespectacledbionic-armed drummer is also completely silent for her brief time on screen.
Wall Slump: Scott, the depressed variation, against a fridge.
Weirdness Censor: Nobody seems to give much thought to people having incredible martial arts skills, exploding into coins, or being able to summon giant monsters with The Power of Rock.
The one point in the movie where someone thinks something genuinely weird is going on is when Stacey sees Matthew Patel break into song and dance. And that's mostly because it's genuinely weird.
That, and when Julie starts swearing and a black Censorship rectangle covers her mouth, the others do take notice. "How are you doing that?"
What Could Have Been: O'Malley was working on the last novel while the movie was being filmed, which is partially why the ending is different in the movie than in the book. The ending to the movie was actually supposed to be much more somber in tone, with Scott and Knives rekindling their relationship and playing Ninja Ninja Revolution together, and Ramona walking through the door alone.
Scott: "Wallace, when my journey began, I was living in an ordinary world. Ramona skated through my dreams and it was like a Call to Adventure, a call I considered refusing. But my mentor, thatís you, told me if I want something bad enough, I have to fight for it. So I did. There were tests, allies, enemies. I approached a deep cave and went through a crazy ordeal, during which I totally seized the sword. Sadly, I died. Then I resurrected! Now I realize what I should have been fighting for all along."
Wrong Girl First: Played with. Scott has a sweet chemistry with Knives (while retaining his Jerk Ass tendencies, he even comments to his sister that he's not sure if he's doing it because he wants to or because he's going crazy) until he sees Ramona Flowers for the first time. After that he grows even more callous with Knives until he finally (sort of) dumps her. Towards the end of the movie, after some serious growing up on the part of Scott, he and Knives work in-tandem to brutally beat the snot out of Gideon. Ironically, Scott is finally grown up enough to be with the 17-year old girl. Of course, I Want My Beloved to Be Happy kicks in about this point, leaving Knives as The Woobie, albeit an Iron Woobie.
In the alternate ending contained in the DVD deleted scenes, Ramona initiates an I Want My Beloved to Be Happy at the end of the movie and leaves so that Scott can be with Knives.
Ramona has pink hair when she first meets Scott; she changes her hair color twice more before the end of the film, to blue and green, but never to a standard color.
Knives also puts blue highlights in her hair to compete with Ramona, but these are knocked out before the third fight.
Your Cheating Heart: Scott on both Knives and Ramona, or more specifically, Scott cheated on Knives with Ramona ("What's the difference?" "You weren't wronged?"). Scott got off the hook relatively easy (considering he was killed before either Ramona or Knives could really chew him out for it), unlike in the books...
Your Princess Is in Another Castle: With 20 minutes left in the film, Scott "defeats" Gideon... then Gideon gets back up and kills him. After he restarts at the checkpoint, he beats Gideon for good. Then Nega-Scott shows up.
