Dragon is a green-eyed red dragon of the Shrek franchise. She initially started out as an antagonist, charged with guarding Princess Fiona in her castle, but later reforms and helps Shrek as a supporting protagonist. She is also Donkey's love interest and eventual wife of his.
Dragon first appears while guarding the derelict castle which serves as Princess Fiona’s prison.
It can be assumed that this is her long-time, permanent domicile, since the castle houses a large hoard of treasure and is littered with bones, armor, and weapons of the many unsuccessful knights who tried to rescue Fiona.
While searching for the princess, Shrek and Donkey become separated within the castle. Dragon traps Donkey on a stone pinnacle, intent on eating him like so many other intruders. Out of desperation, Donkey smooth talks Dragon with compliments, causing her to become infatuated and spare his life.
When Dragon traps Donkey on a broken bridge, Donkey uses his charming and smooth talk to seduce her to not eating him. In conclusion, Dragon flashes her eyelashes at him and blows a smoke ring of a heart. Dragon grabs an unwilling Donkey with her mouth and hauls him back to her lair, shaking her hips back and forth happily and swaying her long tail around as she walks away. She wraps him up in her tail, trapping and squeezing him in her coils and attempts to flirt with him persistently. Her attraction initially appears quite one-sided, but this does little to dissuade her. She makes the first move by lighting the hanging chandelier above her with her fire breath, lifting Donkey in her tail, puckering her lips and leaning in closer for an attempt to kiss him. Unfortunately for her, Shrek intervenes right at that moment to rescue his companion. He swings over them with the chandelier's heavy chain, drops onto her tail and frees Donkey from her tight embrace. This leads Dragon to accidentally kiss Shrek's butt instead. Infuriated, Dragon resumes her rampage, but Shrek manages to collar her with the chandelier. In order to prevent Dragon from pursuing them across the bridge, Shrek pins the chain links with a sword. This gambit saves Shrek, Donkey, and Fiona as they flee to safety. Dragon is left alone and devastated.
Later, Shrek angrily berates Donkey and the pair part ways. A brooding Donkey discovers Dragon, weeping with loneliness by a brook. While her escape from the castle is unexplained, Dragon clearly has no wish to return to her old life. Feeling sorry for her, Donkey overcomes his initial hesitation and approaches the forlorn dragon, whereupon the two reconcile.
A tamed Dragon helps Shrek and Donkey prevent Fiona’s wedding to Farquaad by flying them to Duloc. Upon landing, Donkey tells Dragon to have fun – which entails her chasing off some local knights. However, Shrek’s failure to rescue Fiona from Farquaad’s clutches prompts the ogre to whistle for Dragon. At this point, Dragon intervenes by breaking through a glass window and devouring Farquaad. Donkey, riding her head, threatens the assembly by claiming "I have a dragon here and I'm not afraid to use it". This restores peace, since everyone present is glad to be rid of Farquaad. He is later seen again in her stomach, but the events of Shrek 4-D confirm his inevitable death by digestion.
During Shrek and Fiona’s wedding celebration at the swamp, Dragon cavorts with the rest of the fairy tale creatures. As the newlyweds leave in their carriage, she catches the bouquet thrown by Fiona and lovingly presents the flowers to a flustered Donkey.
A later karaoke number was produced for the CD of Shrek. One scene features the two lovebirds performing a song-and-dance. While Donkey sings a rendition of Baby Got Back, Dragon provocatively shakes her backside at the camera – eventually knocking her boyfriend off his feet with her swaying tail.
This short film was produced as the audio-visual media of a Universal Studios ride, but it was released as an additional featurette along with the original Shrek film. Dragon has a prominent role in this production, first helping Shrek and Donkey get away from an animated dragon statue magically brought to life by the ghost of Lord Farquaad, then later taking Shrek and Fiona on her back to their honeymoon hotel. Dragon's aerial maneuvers through a narrow defile causes the pursuing stone dragon to break its wings off, effectively terminating the chase. Dragon saves them again as they plunge over a waterfall, and ultimately, incinerates Farquaad's ghost with her fiery breath, finally finishing the job she began when she swallowed him in the first Shrek film.
While not stated, this film implies that Dragon and Donkey got married at some point following the events of Shrek. In the beginning, Dragon is only briefly mentioned by Donkey to be acting 'all moody and stuff lately'. She does not appear until the very end of the film (in an extra inter-credits scene) – accompanied by her and Donkey’s hybrid children.
Initially, Dragon was intended to have a more meaningful role in the original storyline. When Shrek, Donkey, and Puss were changed by Fairy Godmother's magic potion, Dragon transformed as well, into a talking Pegasus, the perfect match to Donkey's transformation into a handsome stallion. She was meant to join the other fairytale creatures as they broke Shrek, Donkey, and Puss out of jail, but she was ultimately cut from the film, the reasoning being that she had too much to say and it would have been too difficult to hide her pregnancy. The filmmakers stated, however, that Dragon did still transform proving her to be Donkey's true love.
The "mutant children" are hybrids with mostly donkey features, but sporting dragon wings and tails, and an ability to fly and breathe fire.
Shrek the Third
Dragon plays a more consistent role in this film. Her child-rearing responsibilities prevent her from accompanying Shrek and Donkey on their quest, choosing instead to stay behind with Fiona and the other princesses. When Fiona announces her pregnancy, Dragon is shown to be happy for her.
Despite her size and ferocity, Dragon gets captured relatively easily by Prince Charming and his allies during their attempt to take over the kingdom of Far Far Away.
Once the Dronkeys are released, Dragon joins the battle to recapture the Kingdom, turning the tide by tipping over Rapunzel's model tower that crushes Prince Charming to death.
She and her family can be seen during the credits sequence, visiting the swamp, with the Dronkeys playing with Shrek and Fiona’s children.
Shrek the Halls
This made-for television Christmas special takes place shortly after Shrek the Third.
Along with other characters, Dragon, Donkey and the Dronkeys show up uninvited at Shrek's home on Christmas Eve, where they create chaos with their antics. Dragon unintentionally destroys the ogres' supper when she breathes fire into the chimney to grow the flames in the fireplace, and she shakes the earth by dancing.
Later on she playfully drops a pile of snow from a tree branch onto Donkey, though Donkey remains utterly clueless as to who dropped the snow on him.
Shrek Forever After
At the film's beginning, Dragon flies the Shrek family and Donkey from their swamp to the Kingdom of Far Far Away to celebrate the Ogre Triplets’ first birthday. When they arrive, Dragon and Donkey share a brief kiss and he tells her not to eat the valet.
Dragon’s reappears in Rumpel's palace when he releases her to devour Shrek and Fiona, now chained to the walls. No explanation is given for how Dragon was captured. Having never met Donkey or any of his friends, Dragon fails to recognize them.
Donkey and Puss save Shrek and Fiona by dropping part of a huge disco ball on the dragon’s head, this stuns her but only temporarily. In desperation, Shrek encourages Donkey to "woo" his wife. Donkey desperately turns on the charm and even puckers up for a kiss, but Dragon only response is to gobble him up instead. Before Donkey gets swallowed, however, Puss stabs Dragon in the backside with his sword, causing her to bellow and spit her prey out. Humorously, Donkey misinterprets this predatory act as some form of “kiss” and happily shouts out “I'll call you!” Dragon then continues to hunt Shrek and Fiona, but quickly gets thwarted by them and ends up muzzled and trussed up in chains.
At the end of the film, with the original universe restored, Dragon returns to her normal, more benign personality. The ensuing Shrek karaoke scene even features Dragon playfully gobbling her husband as she had done in the alternate world, but instead of actually trying to eat him, this time she opens her mouth to reveal him completely unharmed and very happy.
Dragon and the Dronkeys were completely absent from this film.
