4x

4x is a non-binary ship between Four and X from the Battle for Dream Island fandom.

X finds out his value
Four seems to be caring for X, as he helps him find his value, which happens to be 7.

Battle for BFDI/BFB
Four's behavior towards X is a bit more mean-spirited. Then he sends X to the "Burn Center" and makes him cry, telling him no one noticed he was missing and reminding him he only recently discovered his value.

Four makes X fall and cry, simply for making a translation mistake at Cake at Stake. Despite this, X still assists Four later on.

Four gets angry at X for saying what he wanted to say. X tells Four to screech him so he can get it over with, but Four says he would do something "much worse." Off-screen, Four cuts one of X's legs off, and sends him to the "Limb Reattachment Center." X is seen at the end of the episode with his leg reattached with a bandage.

The number of votes was incorrectly stated in that episode by Four. X quickly corrected the mistake. Four also allows X to recite the votes of some of Beep's team members. However, Four is quickly killed and he is merged into Donut, stopping them from interacting further.

X returns as Gelatin pulled him out of Fries. X may miss Four since he ran away before Four got multiplied by Zero. It's shown that they have a healthy friendship in "Enter The Exit", despite all the things Four's done. X indeed misses Four and is very happy to see Four back. Four tells X that he did a good job hosting BFB, although he seemed angry at first.

X corrects Four by telling them it's the eleventh contest, and how Four has missed a lot. He helps Four by demonstrating the challenge.

X and Four switch bodies with each other. Near the beginning of the episode, they're seen laughing together, implying they are sharing a funny conversation. Before the Cake at Stake starts Four (disguised as X) leaned on X (disguised as Four), causing the disguised Four to slap the disguised X. Later, X hosts Cake at Stake. Four gets back at X for stealing his line in Fortunate Ben by stealing X's line and stating, "Now you know how it feels!" Later, Fanny tells the disguised X to recover Bubble, but X doesn't know what to do, so Four recovers Bubble for them. Fanny and Lightning notice that the two have switched bodies, so they shapeshift back into their normal selves. Later, while announcing that Team Ice Cube! is UFE, they switch bodies again. X, disguised as Four, makes a bad joke. Four, disguised as X, calls him out for this, but X reminds Four that their bodies are switched again, so technically, it's Four's bad joke.

When X asks if it wouldn't hurt to let Ice Cube watch Team Ice Cube!'s Cake at Stake, Four, in an annoyed manner, agrees. when Four describes the challenge, they state that they can't let X find their treasure because they must be X's only treasure.

When Four is in pain from Firey Jr's fire, X tries to give them a juice box to make them feel better. X later appears with another juice box for Four, but Four assumes that X is going to switch to Two's show. X tries to explain themselves, but Four sadly tells him to just go. X, not sure what to do, ends up sticking with Two.

Four is too upset to continue hosting the show due to not knowing where their co-host is. When Four learns from Taco and Firey that they know where X is, he perks up as they might be able to get X back. In the stinger ending, Four hugs X and says they're so happy they're back. Four asks if X feels the same and X says it depends on how good they are at pattycake. Four calls themselves super pro, so X is happy to be back as well.

X reveals that Four promised to stop screeching after they screech at Lollipop, to which Four replies with, "whoops." When X starts the contest by saying "G-G-GO!", Four says "You went for that for that one huh?", X just replies yes. At the end of the challenge, Four and X speak at the same time while announcing how each team did, along with giving the teams their names.

Four acts a lot more sensitive to X. They're angry when Ruby's supervan has driven over X's aloe vera 73 times, but reluctantly agree to proceed with Cake at Stake when they wanted to tell the contestants to respect them more, and base the challenge around helping his co-host out by making the plants grow. After Cake at Stake, Four reminds X when they're to do their snap thing to eliminate Spongy. When X begins to burn because of the sun, Four provides ice for the contestants to use to help them. Once the aloe vera has grown taller than Four, they claim all of X's problems are solved. X tells them they aren't as they're still on fire, but Four is oblivious. In the stinger ending, X tells Four that there is still a problem, which Four still doesn't seem to get, but decides to make it the next episode's challenge, much to X's dismay.

Four's promise to extinguish X was proved to fruition when Four said that cooling down X will add points to the challenge while hurting him will reduce points. The two teams try to do things to X to increase their points while sabotaging each other. Eventually, the teams did things that would make them lose points, with both hosts subtracting them every time. In the stinger, Four compliments X on his garden, which was in fact, Flower standing on a pot. When she asks them how long will she stand in the pot, Four silenced her. X said that she could leave in about 2.5-3 weeks.

Four tells X to quickly snap their fingers to eliminate Loser. When X says that they'll scan the receivers with his satisfaction detector, Four angrily tells them not to show off, which makes X sad.

Four has the Have Nots watch over the prize so that they could help X untwist their nubs. X says that they would be the judge in the court case contest, but Four tells them that he's doing that. Later, X catches Firey returning the diary and immediately reports back to Four to tell them. Four just scans X's brain, which X seems thrilled about until they remind Four to keep their secrets. X then rushes back to grab the diary and give it to Four.

X announces the new stage in the game right when Four was about to, annoying them. Four finds it sweet that Gelatin made a party for X, but angrily scores him with 0/10 since the parties were supposed to be for them.

Four asks X what to do about the new contestant that keeps getting on their nerves. It's X's suggestion to give them a difficult challenge since they haven't won any before. He fears they'll lose and be voted out. Four likes X's idea and calls him a true blue friend. X blankly states that they're not blue, making Four angry. Seconds later, Four is shown recovering X.

Four refers to X as the best co-host money can buy. In response, X asks if they are supposed to be paid, and Four tells him not to shout. When X says that they get bored co-hosting by themselves, Four says that they don't do anything, and brings up X getting so bored of a previous challenge that they left the courtroom. X brushes off the comment, agreeing that they're great and deserve a co-host. During Cake at Stake, X asks Purple Face for a Cake at Stake prize. Four says that they could've just gotten a cake, and X ignores him. Later, Four says that he's been thinking about doing stand-up and X says that they would watch his act. After entering the World's Largest Oven, Four is shown getting jealous when Leafy compliments X twice about how he's a good, caring host.

As X attempts to recover Purple Face, he is seen trying to get a hold of it. They fail to do so successfully, but Four encourages them to keep trying, saying that recovery isn't easy to learn. X then asks Four to bring Purple Face back, but Four refuses, saying X must figure it out. Later, after the Announcer arrives, Four asks X for ideas, and X tells Four about an idea for a hotel for food. Four tells him he needs ideas on how to get rid of the Announcer, which makes X notice that "Announcer stuff" is going on, and says he should pay attention more. X tells Four he has a sneaky idea to get rid of the Announcer, which includes him going over and telling the Announcer to go away and calling him a dork, which he apologizes for. When that plan does not work, X tells Four he has one more idea, which is to panic. X begins panicking, making Four mad. When X managed to recover Purple Face, Four is pleased and congratulates him. When Four notices the contestants haven't grown attached to him, he feels excluded and gets sad. X asks if he's doing okay, and Four tells him they've lost all control. X tells him it'll be okay. When Four sinks into the ground and becomes one with the desert, X frantically tries to ask him what happened. He gets a response from Gelatin but is not worried about his dirt-eating thing, and is more concerned about Four sinking into the Earth. In the stinger of the episode, X tries to ask Four if they will be coming back soon. When they get no response they get sad.

X is shown sad that Four is gone. In response to the contestants' request for aid in saving BFB's budget, they refuse, even asking why they should continue because their best friend is gone.

X sits in the spot that Four sank into, refusing to leave his side, especially knowing that it's the last episode of season Four started. After talking with Profily, who suggested that Four would come back if everyone showed that they care, X leaves to get help from the contestants. As everyone chases Four, X is in disbelief over how much Four is protesting since he is the biggest BFDI fan. The flashback shows X asking Four if he's still watching BFDI while Four interrupts him with his favorite line from BFDI 17. When Four turns back to normal, Four says they missed X and call him a true yellow friend. X agrees that Four is cool when Announcer says he's cool. Four and X are shown talking to each other with the Announcer and Purple Face over a possible season 6.
