Dragonfruit

Dragonfruit is the het ship between Mei and Red Son from the Lego Monkie Kid fandom.

Backstory
Mei initially mistook Red Son for MK's friend when she saw Red Son chasing MK, believing they were racing and suggested to MK that he should invite Red Son to play Monkey Mech with them. However, MK replied that Red Son tried to kill him. This prompts Mei to half-jokingly ask MK where Red Son lives so that she could nuke him. Later on, when MK's team believed MK had been killed, a furious Mei insisted on fighting Red Son herself. Mei then uses her power to fight him.

Mei is at first distrustful of Red Son after he shows up on the Team Dronecopter and tackles him along with Pigsy and a reluctant Sandy. Mei slowly calms down after Red Son reveals that the reason he came to them was because his father was trapped by the Spider Queen. Red Son very depressingly asks the Monkie Kids for the ship so he can save his father, After MK makes the decision to let him help them defeat the Spider Queen, Mei questions it for a bit. Mei then hears MK out and reluctantly agrees.

When Red Son brings them to the Celestial Realm to get the ingredients they needed for the antidote, Mei teased Red Son and refuses to let him go after the Immortal Peach on his own. Red Son is condescending to her, so she bites him on the hand and states she's gonna keep him where she can see him. Once they are in Celestial Realm, the team is divided into groups, with Mei paired up with Red Son. While looking for a peach, Mei reminded Red Son of when he helped MK defeat his father, making him angry and defensive. Mei then jokes that since he was helping them now, he was a hero.

Red Son then makes a note to put her on his hit list. She and Red Son are both angered when Strong Spider insinuates that they are in a romantic relationship. While the team fought against the Spider Queen, Red Son attempted to protect Mei but it only ended up in both of them captured. When DBK frees his son from the cocoon Spider Queen wrapped him in, Red Son in turn frees Mei. When Mei tells his father about how Red Son acted "like a real hero", he yells at her before teleporting himself and his father away.

In the season three special, Red Son becomes Mei's mentor after she begins to lose control of the Samadhi fire. During this special, Red Son and Mei form some sort of bond. They trained together and Red Son teaches Mei how to meditate to stay calm and control the fire. During a break from the training, a softer side of Red Son is shown, as he seems to care about Mei and his parents for a few moments.

Later on, Mei is kidnapped by the Lady Bone Demon and a corrupted Sun Wukong because she is the vessel of the Samadhi fire. Red Son appears worried about her, and reluctantly goes with MK to come up with a plan to defeat the Lady Bone Demon. When Red Son, and others find Mei in the Lady Bone Demon's realm, Red Son doesn't think twice and immediately jumps to defend and save her. The Lady Bone Demon then begins to forcibly rip the Samadhi Fire out of Mei, Red Son warns the others to leave and he stays to get through to Mei. This is the point in time for the first time he refers to her by her name and not "dragon girl." He does get through to her and defeats the Lady Bone Demon with MK. The final frame with Red Son and Mei is them cuddling after the battle.

In season four, Red Son comments on one of Mei's streams. It doesn't show what he comments, however.

Fanon
Dragonfruit is one of the most popular het ships in the fandom. People seem to like the enemy to lovers trope. Many people like to draw Mei and Redson with Redson being a tsundere and Mei being very, very tolerant, finding his antics cute. This ship seemed to become a bit more popular in season 3, as Redson and Mei had more screentime. People freaked out by the last Dragonfruit frame in the Season 3 special, which shows the two cuddling. Some people like to ship Mei and Redson with MK, as a polyamorous ship. People like to headcanon Redson and Mei text with one another, after the season two scene where Redson pockets Mei's phone after she teases him for being a hero. People like to draw Mei as the one with more romantic initiative. Some people headcanon that Red Son is genderfluid and Mei as non-binary.
