Fourth wall

At times, characters in the Sonic the Hedgehog series will say something that implies that they know they are fictional characters in a video game, movie, television show, or book; this is referred to as breaking the fourth wall. The term originated from plays, in which actors would do something that involved the audience. Due to a stage looking similar to a box with two walls on the left and right, and two more in the front and back; the front wall, or the direction where the audience is sitting, is called the fourth wall.

Common elements

 * Characters tell the player about commands such as  "Press the A Button to Jump. Press the A button again to do a Homing Attack".
 * After finishing a stage, the character(s) will strike a pose toward the player and comment on the Rank they receive.
 * In the 2D games, characters will look at the player and act impatiently if left stationary for a while.
 * In most character artwork for games, TV shows, etc, the characters often pose towards the viewer.

Sonic 1/2/3/&amp; Knuckles/4

 * When the character is idle for a while, the character will turn to the player and perform various actions.
 * If Sonic is idle, he'll turn to the player, giving an annoyed look and start tapping his foot. In Sonic 2 and Sonic 4, he will look at his arm as if he had a watch with him. In Sonic 3, if the player waits long enough, Sonic will look at the player and point in the direction he's facing.
 * If Knuckles is idle, he'll turn to the camera and start punching.
 * If Tails is idle, he'll look at the player and yawn.
 * When the player hits Dr. Robotnik, he'll look to the player with a shocked expression. If he hits the player, he'll laugh directly at the player.
 * After finishing the game in Sonic 1 or Sonic 4, Sonic will turn to the camera and strike one final pose.
 * After finishing Sonic the Hedgehog 3 & Knuckles, Tails can be seen waving at the player.
 * After the credits from the true ending of Sonic 1 and true ending of the Sonic 2 2013 re-release by Christian Whitehead, Robotnik angrily will crush the title: "End", steadily.

Sonic the Hedgehog CD

 * If Sonic is idle for three minutes, he'll turn to the player and say "I'm outta here!" and jump off the screen with an annoyed look on his face while still looking at the player. This results in an instant Game Over, regardless of how many lives the player has.
 * Before the player is able to control Sonic in the Special Stage, Sonic will turn around, as though saying "Hey! Pay attention!"
 * Before Sonic races against Metal Sonic, Metal will do Sonic's finger wave toward the player. If the player loses against Metal Sonic, he'll do the same thing.
 * In the good ending, Sonic will glance, then turn to the player and pose before the credits play.
 * There is an unlockable extra which has a picture of Tails saying to the player "See you next game!"

Knuckles' Chaotix

 * When Robotnik is being lifted by Metal Sonic, he is seen laughing at the player.

Sonic Adventure

 * If the player moves the camera around a lot while playing as Knuckles, he'll state that he doesn't want to fall.
 * After finishing their respected stories, the character (with the exception of Gamma) will turn to the player and strike one final pose, as though thanking the player for their help.

 * During the CGI ending for the Hero Story, after shutting down the Eclipse Cannon, Sonic turns to the camera, smiles and gives a thumbs up.
 * During the title screen, after enough demos play, a character can be heard saying "Sonic Team!"
 * During the City Escape stage, there are posters telling players that "Playing SA2 is a habit forming" and to not turn off their Dreamcast. In the remake, Sonic Adventure 2: Battle, the posters say not to turn off their GameCube. In it's PS3/Xbox 360/PC Re-release, the posters say not to turn off their consoles/PC even though their console/computer is not mentioned.
 * There are also posters of Soap shoes, which are what Sega helped promote at the time. That has since been removed in the PS3/Xbox 360 re-release due to licensing issues. Because of this, posters of Sonic Team are also present throughout the stage as a replacement to the Soap shoes ads, although it can be restored in the PC version.
 * When starting a level the character will say something about what happened or what is going to happen directed towards the player.

 * During the Tornado Special Stage, the character will turn to the player and do something like give a thumbs up or wave.

 * When Team Chaotix face the Egg Emperor, Charmy asks if it's the final stage, Vector the Crocodile says that it's not (foreshadowing the final battle against Neo Metal Sonic).
 * In Team Rose's opening cinematic, Amy is holding a newspaper clipping with a picture of Sonic (Metal Sonic in disguise) carrying Froggy and Chocola. The article on the newspaper appears to be an ad for a portable "Palm" version of Sonic the Hedgehog.
 * While selecting Shadow or Omega to be Team Dark's leader, if the player uses the first-person camera to look at Rouge, she will turn her head in the player's direction and winks at him/her.
 * When playing as Team Dark, after being idle for a while Shadow will often remark (mostly at the start of the game) "no need to rush" which is both aimed at the player and also saying that there is no time limit.
 * If Team Chaotix gets an E rank, Espio says: "Insulting! Your training has been a waste of time!" (Referring to the player).

Sega Superstars

 * At the start on the Sonic game, Sonic (or Shadow) will look at the player and give a thumbs up.

Shadow the Hedgehog

 * When touching the Hint Ring during the final stage of Expert Mode, Eggman can be heard telling Shadow (i.e. the player) "This is the final stage!"
 * When an ally character appears for the first time, they'll turn to the camera and pose.
 * In the Final Haunt level, when Shadow meets Sonic, Sonic will say "Hey Shadow, looks like we've reached the climax of this little game here." Of course, Sonic could just be making a joke. In Sonic and the Secret Rings, Sonic admits that everything is fun and games.
 * In the cutscene before the Lethal Highway stage, Sonic says "Welcome to the next level." This phrase was also a reference to one of the slogans used for promoting the Sega Genesis.

Sonic Rush

 * If the player taps Sonic with the stylus, he'll swing his arms, as though saying "Come on! Let's go!"
 * If Blaze is tapped with the stylus, she'll jump like a scared cat, stamp her foot, and turn her back to the player while tapping her foot until the player controls Blaze again or taps her again.

Sonic the Hedgeh​og (2006)

 * After Rouge briefly talks to GUN about the whereabouts of E-123 Omega, she will pose and give the player a seductive facial expression.

Sonic Rush Adventure

 * In the final part of the battle against the Ghost Kraken, it will shoot an ink ball at the screen, obscuring the player's vision. The player can wipe away the ink blot with the stylus, but this method is time-consuming.
 * Just like Sonic Rush, Sonic and Blaze will react when they are touched by the stylus on the lower screen (Sonic stretches while Blaze lifts herself in the air).

Sonic Rivals

 * When Sonic reaches the Sky Park, Sonic will say "Looks like we've been teleported to a completely different location...", possibly referring to both him and the player.

Sonic Rivals 2

 * In Neon Palace Zone, there are some neon signs with all the playable characters' icons, also some of them have the logo and the game title.

Sonic Riders/Riders: Zero Gravity

 * In the animated intro to Sonic Riders, Sonic gives the player the "Peace"/"Victory" sign just as he passes the camera.
 * After starting a race in Sonic Riders: Zero Gravity, the character will turn around and look at the player.
 * When performing an "X"-Rank Trick in later games, the character will turn to the player, as he/she is saying "Good job!"

Super Smash Bros. Brawl

 * During Sonic's Side Taunt (the rev-up animation of his Super Peel Out from Sonic CD), he'll turn to the player (possibly the opponent) while saying "You're too slow!"
 * During Subspace Emissary, Sonic appears before the final fight against Tabuu. This could be a nod to Sega's late acceptance to let Sonic join Brawl.
 * If the player fights Sonic while playing as Solid Snake and contacts Otacon, Snake will say that he doesn't like Sonic for some reason, but will not elaborate why. Otacon will then state that many fans are happy that he's in Brawl. Snake's unexplained dislike toward Sonic could, among other things, be a nod to the Sonic games selling better than the Metal Gear games (or simply, in relation to this, because the hype for Sonic's inclusion in Brawl overshadowed that for Snake's own inclusion).
 * It's more highly possible behind this is the fact that the Japanese voice actor for Snake, Akio Ōtsuka, is the son of Dr. Eggman's voice actor, Chikao Ōtsuka.

Sonic Chronicles: The Dark Brotherhood

 * Tails will constantly remind Sonic to save the game before certain areas.
 * Sonic and Tails cite the credits themselves, even making various comments; such as Sonic pointing out that one of the members who worked on the game is named "Miles." Omega eventually joins in, but ends up putting Sonic to sleep.

Sonic Unleashed

 * After Sonic realizes that Chip lost his memory, he asks the player if he fell on him.
 * After Sonic sulks away because Amy didn't recognize him as a Werehog, Chip will offer him chocolate, but Sonic will refuse. Chip will then shrug at the player before flying after him.
 * While Sonic is being graded in the 360/PS3 versions, he and Chip will look directly at the results.
 * After Eggman fails to kick Orbot and falls flat on his back, Orbot turns to the player, points at Eggman, and chuckles before the Doctor gets back up.
 * While visiting any Gaia Gate, if Sonic is idle, he'll sometimes lay down sideways with his hand propping up his head, stretching or turning around, as if heard something, and look at the area behind him. Sonic's reaction, named first, will also work in any Day-Stage when he's idle for a while.

Sonic & Sega All-Stars Racing

 * During races, Sonic or some of the other characters will look at the player.
 * When Big gains first place, he'll put his hand on the camera to stop himself, jump off his bike, and pose.
 * In the CGI opening, after just beating Eggman and when gaining first place, Sonic give the player his famous thumbs up.
 * At the title screen, various characters will drive up, look at the player, and perform various actions.
 * When Amy won, her car would crash back-first into the camera, she'd step out, and giggled as if the "cameraman" was in a fairly sticky situation.

Sonic Free Riders

 * Omochao seems to be talking as though the player is watching television (although he is speaking to the "camera" that some of the other characters can see). It's also supported by the fact that the game is somewhat featured like a television show.
 * During Kinect calibration, characters will occasionally motion towards the player before jumping on their Gear.
 * When characters do their 'X' tricks, they would glance toward the player.

Sonic Colors

 * When Tails corrects Sonic by telling him that it's pronounced "Wisps", Sonic turns to the camera and tells the player, "Yeah. I'll just stick with 'aliens,' if that's okay with everybody."
 * In the CGI opening, a White Wisp looks at the camera in wonder, as though trying to look at something.

 * If the player enters the Death Egg Robot boss gate as Modern Sonic, in the cutscene "Through The Glass," Modern Sonic will look at the player and say, "Another Sonic! What!?"
 * At the start of Speed Highway and some challenges, Modern Sonic will look at the player and give a thumbs up.
 * In the second-to-last cutscene, the hammerspace concept is referenced by Classic Tails, who asks his modern self about where Sonic puts all his gold rings. Modern Tails then says that he has no idea. However, this isn't necessarily breaking the fourth wall, so much as "leaning" on it.
 * When Classic Tails refers to Classic Eggman as "Dr. Robotnik", Classic Eggman says "Nobody calls me THAT anymore" considering that he referred to himself as Dr. Robotnik until after Sonic Adventure, this comment is partly directed at the player.
 * In the post-credits scene, after Modern Eggman tells his younger self, "It'll be your plan pretty soon," Classic Eggman says that he will dedicate the rest of his life to forgetting it at the camera.

Sonic the Hedgehog 4: Episode I

 * Same as Episode II, excluding Tails.

 * When Sonic is free-falling, if the player doesn't hold down the R-trigger button, he will turn around so his back is facing the ground, and look at the player as if to say "Oh, come on!".

Sonic Boom: Rise of Lyric

 * In the cutscene right before the Ocean Purification Plant, Tails briefly looks towards the screen while Knuckles is attempting to boss the group around, as if to say: "Yep, there's Knuckles for you."
 * In another cutscene, Knuckles will playfully hit Sonic on the back, causing him to lose a ring and fall.

Sonic Boom: Shattered Crystal

 * In the cutscene before Shadow Canyons, after Sonic makes a pun on the word "shadow", Tails winks towards the camera and says: "And there's your irony!"

Sonic Boom: Fire & Ice

 * When Sonic and Amy first meet D-Fekt, Sonic says to Amy, "Looks like Eggman lost one of his toys". Amy then says, "Yeah, he'd make a great action figure if our adventures were ever merchandised." and winks at the camera.

 * When Sonic rushed off to save Sally from the trees, he uses a full panel to tell the viewer about the story and what he hopes he'll be able to do, all while using all the bad tree puns that haven't been used up to that point.

The good guy never gets killed in an anime and the bad guy like myself never wins. In other words, not matter how hard we try, the show makers will always make us lose!"

 * Vector and Espio give a description of themselves to the viewer. These descriptions take so long that when Charmy asks if it's his turn yet, Vector informs him that they don't have enough time, and that they have to cut to commercial.
