Bad Bad Acting: This series is built off shoddy acting. Here's an example form Vengeance:
Knuckles: Sonic man, I got an idea. We can take up to that.. that crane thing up there that's what it's called I think a crane.
Batman Gambit: Silver's ultimate goal in Vengeance revolves around this.
Berserk Button: Don't ever say you used Tails' tacos to summon a giant monster.
Or say you're hungry for one yourself. Amy and Charmy found this out the hard way.
Bi the Way: Knuckles is usually straight in the series, but that changes in Doom Ship The Movie when he notices Espio's horn, which leads into a romance, though it ends in tragedy.
Camera Abuse: In Gmod, the camera works very much like a tripod. Cue the numerous moments when someone decides to touch it and the camera topples over, sometimes sending it into a spinning frenzy or launching it across the room.
National Stereotypes: All over the place. The easiest and probably most offensive is Tails' Mexican heritage.
Nice Job Breaking It, Hero: In yet another attempt to "do'' Sonic, Amy instead decides to have sex with one of the many Sonic clones on Blaze's starship, accidentally releasing everyone else's clones, including Dr. Eggman's.
Nice Job Fixing It, Villain: Sort of. If Satan didn't go and announce he used the power of Tails' tacos, he wouldn't be beaten to death by a young mexican fox who suddenly went insane.
Perpetual Poverty: In effect starting from Vengeance; the team repeatedly mentions not eating for days, but no one has shown signs of starving or being physically weaker from the lack of food. For instance, even on an empty stomach, Knuckles is still able to defeat a gang of zombies without receiving any type of body damage or bites.
Potty Emergency: Sonic and Shadow in Doom Ship once the Swedish meatballs Vector fed them earlier kick in. They find Rouge and Tails waiting outside while Amy uses the restroom.
Power Incontinence: Sort of. Sonic's "Hornhog" form in Vengeance causes him to become hostile and having a thing for raping his victims to death. He can still speak and even questions what happened to him, though the main characters remain scared to approach Sonic in Hornhog form.
Sealed Evil in a Can: Thanks to the logic that any of Blaze's clones that has a living counterpart on Earth that dies in some way inherits the memories of their deceased counterpart, the clone of Dr. Eggman accidentally released by Amy is just as dangerous as the real one Sonic killed an episode prior.
Serial Rapist: Hornhog Sonic. The only one that sees this as a good thing is Amy, since she is constantly trying to get near Sonic.
Spoiler Opening: The preview images for both Origins and Vengeance reveal several key plot elements. Origins' reveals that Knuckles will become zombified and Sonic will have to power up using Rouge's boobs, Vengeance spoils Sonic becoming a "Hornhog" and the return of both Knuckles and Silver after they were killed off in prior episodes.
Doom Ship The Movie spoils that Eggman will join the heroes, Knuckles and Espio will romance, a sea monster will attack the ship and Tails will pull a lifeboat out of Rouge's ass to escape.
Sonic even lampshades the spoiler-tier thumbnails in both Origins and Vengeance.
Swallowed Whole: In Vengeance, Monster Silver kills Shadow this way, however Silver is later impaled on some poles, meaning Shadow could still be alive and escaped from Silver's dead body offscreen.
The next episode Space confirms that Shadow did indeed die inside Silver's body, since according to Blaze, Shadow's life readings have dropped to zero, resulting in the team picking up a clone of Shadow during their visit on Blaze's Starship.
Doom Ship shows Sonic and Tails being swallowed by the giant sea monster that attacks Vector's ship, leading to the two depositing two of Vector's laxative "meatballs" in the stomach, causing the monster back to suddenly erupt with feces, expelling Sonic and Tails in the process.
Take That: In the first episode released, Sonic's voice was meant to be a Take That towards the then-current voice actor for Sonic, Jason Griffith. It later changed to a Roger Craig SmithTake That after Sega switched official voice actors.
Doom Ship shows Tails' hatred towards Taco Bell.
Tails: Oh this would've never happened if we just had tacos!
Sonic: Heh. What are you f***ing kidding me? Have you ever had Taco Bell before?
Tails: Taco Bell does not serve tacos, they serve... dog food!
Take That, Audience!: Near the end of Vengeance, Sonic makes a quick stab at viewers who take the series seriously and don't see it as a Stylistic Suck series. Another such stunt would appear in Space.
Toilet Humor: The entire main cast sans Knuckles in Doom Ship all rush and argue over the restroom on Vector's ship after experiencing harsh diarrhea from the odd-looking meatballs they ate earlier. Things don't get much better when Tails catches Charmy about to munch one of his tacos.
The Monster of the Week gets this too when Sonic inserts spare "meatballs" into it's stomach, which causes the sea monster to experience a rather harsh case of diarrhea.
Too Dumb to Live: Knuckles, at least in his first appearance in Origins. When he finds Espio with a zombie bite on his shoulder in Doom Ship, he recognizes it, compared to when Cream had a bite and bit Knuckles in Origins.
Unlikely Hero: In Diaries, it is ultimately Tails that defeats Satan.
Verbal Tic: Sonic's "Whooba Dooba Doo" phrases, especially in Vengeance.
What Happened to the Mouse?: For a series based around zombies, the only scene to contain any form of zombie attack in Space is the opening attack in the deserted city's sewers.
