||A wrestler video game villain is seen only wearing tight undergarments; in the same scene a female villain appears in a low cut dress.
Ralph finds a pair of men's undergarments in a lost-and-found box and is grossed out. He later knocks out a solider to steal his uniform and dresses the solider in only the undergarments so he won't be completely naked while locked in a closet.
||The movie is a cartoon adventure based on video games and contains numerous slapstick scenes of characters running into things and getting hit with comical objects and video game style fighting.
A sequence involves Ralph entering a dark, modern "first-person shooter" game called Hero's Duty. This game contains scenes of automatic gun firing, with bullets are replaced by green bursts, and explosions. These automatic weapons are used to shoot at mindless bug creatures which explode in green goo.
A cyborg fighter playfully rips out a zombie's heart and then returns it to him without hurt feelings.
In a flashback intended as comical, a female Sergent explains how a giant bug creature burst into her wedding ceremony and devoured the groom, in one non-explicit "gulp."
In a slapstick scene, Sergent Calhoun repeatedly punches Fix-It Felix in the face which he heals immediately using his superpower. We see his face undergo various deformities, including black eyes, missing teeth and swollen lips and face.
Vanellope crashes a racing cart and spits out a tooth.
Ralph burns his feet in lava like boiling hot diet cola but does not show lasting pain or wounds.
In a nightmare sequence, a character is quickly shown fading into nothingness when a video game is unplugged.
A character, having morphed into a bug monster, is hypnotized by a giant bug zapper and allows himself to be burnt to ash. His death is shown from a tasteful distance. By the "rules" of the movie he dies for good.
Characters throughout have the threat of "dying for real" if they are killed outside their own game.
||Intermittent double entendre insults like "come on you pussy willows", "move your molasses", "like fun you are!" "bull roar!" etc.
A girl makes several jokes about "Hero's Duty," clearly implying that she's thinking of it as "doody,".
||Video game characters are seen drinking from martini glasses in a party sequence.
One of the video games in the movie is called Tapper, which involves a bartender serving mugs to customers which dialog identifies as root beer. Tapper is a real-life video game, not just from this movie, that was controversial in the 1980s because it did in fact involve beer and was sponsored by Budweiser. However, the real game developers later released a kid-friendly version called "Root Beer Tapper." The version in Wreck-It Ralph looks like the original game but calls the mugs root beer.
||Younger viewers may be disturbed and upset by a scene where Ralph destroys the car that he and Vanellope built together.
In the final scene Ralph battles a giant bug monster with the main villain's face on top, which taunts him. This scene is played for dramatic effect and does not have the same comedy as earlier fight scenes. The scene peaks when Ralph attempts to sacrifice himself by jumping into a volcano so it will activate and destroy the main bad guy. Ralph is saved at the last second by Venelope but the villain is not.
Though it is a dream sequence, the game being unplugged and the likeable character of Vanellope disappearing into nothing could be upsetting to some viewers.
When the goofy villain King Candy is revealed as the more serious villain Turbo the unnatural, glitchy transformation may be scary. His later transformation into a bug monster may also be upsetting.
