The Magic Mirror on the Wall is a a supporting character throughout the Shrek series.
The Magic Mirror is brought to Duloc at the request of Lord Farquaad. Farquaad has his captain bring him to the dungeons and asks the mirror if Duloc is the "most perfect kingdom of them all". The mirror tells him that Duloc isn’t a kingdom, since he isn't actually a king, prompting Farquaad to have Thelonious threaten him by smashing a handheld mirror. The Magic Mirror clarifies by saying that while Farquaad isn't a king, he can become one if he simply marries a princess. The mirror presents him with three princesses to choose from: Cinderella, Snow White, and Princess Fiona. After Farquaad chooses Fiona, the mirror attempts to warn him about "the little thing that happens at night" to no avail.
The Magic Mirror is later seen propped up on a easel in Farquaad's room, forced to replay an image of Fiona for him. Farquaad also uses him as a mirror while getting ready for his wedding. The mirror is also seen attending Shrek and Fiona's wedding, and is later seen in Shrek's Karaoke Dance Party.
The Magic Mirror is used as a TV screen in Shrek's home. He reports the news of Shrek, Donkey and Puss in Boots being captured by the guards of Far Far Away and is seen during the song "Livin la Vida Loca".
In the alternative universe he is again being used as a TV screen announcing that Rumpelstiltskin would have an announcement to the people of Far Far Away that if they catch the ogre Shrek they get a grand reward. He also called Rumpel a tyrannical ruler. He appears at the end credits with the rest of the fairytale creatures to help Fiona light the pretty ball.
The Mirror's role is no different than the first film. He still helps Farquaad pick Fiona as his princess, and is used for his amusement.
