Troublemaker!Sans

== Main informations ==
 
Troublemaker!Sans is a Sans OC created by MaruKuroshima for an AU called "Marutale". However, after the end of the story (this AU only has one timeline) he became an out!code and causes troubles in various AUs for fun. He does not hurt anyone though, his crimes are mostly theft (He only robs people who deserve it), pranks, causing a little chaos time to time, cheating in games… But he usually gets away with it because of his inventions and escaping skills. 
== Story ==
•PAST/Before the main storyline : 
•Childhood : 
Troublemaker is the created son of Marutale!Gaster. As a kid, he spent most of his time in the castle of King Asgore and Queen Toriel since Gaster was their friend but also their Royal scientist. Toriel was like a teacher to him, learning him several things such as writing, reading, calculating… But also jokes ! Troublemaker was a very innocent and kid child back then and Toriel loved making this little precious kid laugh. He was also friend with Asriel, who was slightly younger than him, Undyne, who was the child of Eidothea, the former head of the Royal guards, who spent a lot of time with his dad… She pretty much flirted a lot with him but Gaster didn’t really responded to her actions. 
But also with some other kids that would come by time to time such as Alphys, Grillby, Muffet… But it was pretty rare. So he mostly played with Asriel and Undyne (His Papyrus was still a baby back then.) 
Later, the queen and the king adopted Chara, a human child. Chara joined their little group and the children quickly bonded. This group was a spark of hope for their parents who were working on a project about peace between human and monsters. They hoped they could make everything better again and free the monsters, to live in peace and never live another war ever again. 
This hope lasted until Chara’s death. The kingdom, Toriel and Asgore, and the children were devastated. But it wasn’t even all. Asriel went missing for days… Very long days. He eventually came back without Chara’s body… And he came back from the place humans usually fall, meaning he couldn’t cross back the barrier. No one knows what happened but when he came back, he was hurt … And not alone. Another human child fell with him, by trying to help him going back home. It was a kind little girl. She brought back hope for a little while… But not for everyone. Asgore couldn’t take the idea of seeing his son coming back hurt and terrified. He knew something happened and that the humans were behind it. 
At this point, the king had given up the idea of peace between humans and monsters. He has another plan … And got his most loyal friend, Gaster, involved. Gaster volunteered to take care of the human girl, despite having one young child and one baby to take care of. No one suspected anything… But Gaster did exactly what was necessary for Asgore’s plan. Gaster didn’t actually want to do this, but he was very loyal towards Asgore.
Everything could have gone unnoticed if little Sans wasn’t awake, holding a present for his dad… A drawing of their family. The drawing fell on the ground when the child witnessed the scene… His father, his role model, the adult he looked the most after, with the blood and soul of the little girl in his hands. Obviously, the little skeleton got scared but couldn’t do anything against his father, who was way stronger than him. He knew too much… So little Sans didn’t go play with the other kids. He didn’t go learn new things with queen Toriel. His father always come up with excuses and isolate the child somewhere when he was working… Because he knew there was a risk of him telling everyone what he saw. It was the beginning of him trying to learn by himself how to escape situations like this. 
Eventually, the disappearance of the little girl didn’t go unnoticed. Hope was lost again… The kingdom believed in a curse. Humans and monsters weren’t meant to be friends… 
But then… Another child fell in the underground. A very energetic little boy. This time, before anyone could get any hope or even acknowledge of the boy’s presence, Asgore decided to take this matter in his own hands. But once again, he got witnessed… By no other than his own wife. Everything was clear now. Toriel guessed Asgore’s plan and was completely against it. She was disgusted by the man she used to love the most… And decided to leave with Asriel, who was also disgusted and disappointed. He knew his father had something to do with the little girl’s disappearance… His friend. He was never going to see her again, just like Chara. But this event caused chaos in the kingdom. One side was still believing in peace between humans and monsters while the other disagreed. They saw humans as a sign of misfortune, sadness… Peace wasn’t a possibility to them and it created discord among the kingdom itself.
So the underground was split in two halves. One had Toriel as their queen. This part of the underground was the one believing in friendship between humans and monster. The other has Asgore as their king, and this one was against this idea. 
Toriel lived in the ruins, that were like a new castle to her, ever since, with Asriel… Before being joined by Philomena, who came with a little scared skeleton in her arms. It was little Sans. He finally managed to escape and ran to Philomena, the former nanny for used to watch over the kids when they played together. He told her everyone he saw and she decided to take care of him since she always wanted children. Toriel welcomed them with opened arms and Asriel and Sans could continue their friendship safely. However, since little Sans was still a weak child, he couldn’t take his baby brother with him and he missed Papyrus a lot… 
It was the beginning of the discord and rivalry between both sides of the underground. 
 
•Teenage years : 
After living with Toriel, Philomena and Asriel for a few years, Sans eventually grew a little, becoming a teenager alongside Asriel. Their mothers also fell in love after a few years of living together and announced their wedding, which made Sans and Asriel step brothers. Toriel’s side of the underground was delighted of having a second queen and seeing their queen, Toriel, smiling again. 
But her smile faded each time another human fell in the underground and took the decision to go in the other kingdom, trying to go home. No matter what she did, they always left… Then died. Philomena and Asriel were trying their best to cheer up Toriel, which usually worked. Toriel was truly happy with her new wife, she never felt this kind of happiness in years, even though she also loves Asriel dearly and … 
Tries to handle Sans who was turning into a troublemaker. He wasn’t a easy-to-handle teenager. He always tried to go in the other kingdom as well but only to cause troubles on purpose, and every times, Toriel had to send guards to bring him back. 
Toriel and Philomena always tried their best to make him feel loved, but this bratty teenager wasn’t the best at showing affection. But the truth was that he really did love them and saw both of them as mother figures. 
They couldn’t really stop his trouble making behavior but they did try to make him do other activities, to give him other interests… He ended up being interested in robots and machines. They thought he would probably be an engineer someday. If only they knew … 
Years later, Toriel and Philomena gave birth to their new son, Felix. A perfect mix of his mothers and the new source of happiness of their side of the underground. Meanwhile, in the other side, Undyne was training to become a Royal guard. Papyrus was still a child but started to dream of becoming one as well. He wanted to make sure that everything and everyone was in order, pretty much like a policeman. 
Gaster was still loyal to Asgore. Asgore was still mad at humans, blaming them for losing everything… He was hurt, because he initially wanted to protect his son. He was a dad after all. Gaster also regretted his actions but never tried to get Sans back because he knew that his son was now disappointed and scared of him. He was also ashamed but it was too like to turn back. The plan was still ongoing. Eidothea stayed by Gaster’s side but never really told anyone if she was or not for peace between humans and monsters.
The initial goal of peace between human and monsters was very far because there were still a conflict… In the underground itself. Monsters against monsters. It stayed that way for years. 
 
• Adult life : 
As an adult, he moved out from the ruins to live alone in a little house in Snowdin. His trouble making behavior didn’t stop. AT ALL. It got worse. Sans, now known as « Troublemaker » had a new reputation of being someone who caused a lot of troubles in BOTH kingdoms. Small and harmless in the one of his mothers, and bigger in the other kingdom where he is now a wanted criminal. Undyne, as the new head of the Royal guards after the retirement of her mother, Eidothea, was trying to get him arrested with the occasional help of Papyrus, her apprentice. Papyrus was confused of why Sans has left since Gaster never mentioned Asgore’s plan to him. So, alongside wanting to arrest him because he violates the laws all the time, he also wanted answers. Sans however was pretty happy to see his brother being motivated and energetic, despite his motivations being to arrest him, literally. It was a way of checking if Papyrus was okay, and it was enough to him. 
Sans was Undyne’s biggest rival, as he ALWAYS managed to escape from her. Despite not being strong in battle, he was very fast and sneaky enough to be an escaping expert. His tools and devices also helped. 
He left Toriel and Philomena’s house to move alone in a little house in Snowdin. Felix, who was now a child, moved in his room. 
A one day… Another human fell in the underground. That one human who changed everything… Frisk. 
•PRESENT/During the main storyline : 
When Frisk arrived in the underground, Troublemaker was still causing troubles around, especially in Asgore’s kingdom. He seemed amused by this and loved messing with Undyne and Papyrus, as if it was a game to him. 
He didn’t really pay any close attention to Frisk at Frisk since many humans feel before them and always ended up leaving and dying. He thought the same thing would have happened (which made him worried about Toriel and Philomena since it always made them sad.) but this time, things seemed different. 
At first, Frisk stayed for a while. They loved life in Toriel’s kingdom. Monsters were friendly… But they noticed the conflict with the monsters of the other side if the underground, and eventually learned about what happened in the past… 
Frisk also made two friends, Felix and Florian (Monster kid’s name in this AU), these 3 kids thought that this conflict was dumb. So they tried to talk about it with Toriel. Toriel was pretty strict about it : They must leave her side of the Underground, it’s too dangerous. 
But those 3 kids were determined. They proved themselves to her… And as a team, they were pretty strong ! But it wasn’t enough to convince a worried mother. They ended up leaving without permission… Which made her worried sick. Since she was already getting old and tired, Asriel started to replace her, and took the throne while Philomena was taking care of Toriel. Asriel called Troublemaker and asked him to look for the kids, which he accepted. 
He noticed that they were doing pretty well. The kids already had the support of many monsters of Toriel’s kingdom, such as Grillby and Muffet (they’re dating in this AU) and Mettaton (A famous ice-skater in Snowdin)… 
So he disobeyed again and instead of bringing the « FFF trio » home, he watched them closely, making sure nothing happens to them. The trio started to get monsters from Asgore’s kingdom helping them and supporting their cause. Especially Eidothea, Undyne’s mother, who was pretty happy to learn about Toriel and Philomena’s marriage since she was their old friend. They also got Undyne and Papyrus’s support and friendship as well but not from many monsters… They still had enemies, such as Mad mew mew, a popular idol in Hotland but also a human killing machine. Alphys, who also joined, had to hack her system to stop her from hurting the kids. 
But once they arrived to Asgore’s castle… They met him and Gaster, who had changed a lot due to him making experiments on himself in order to find a way to help the king. They tried to talk at first but it was useless. They showed that friendship between humans and monsters was possible, but only if everyone makes efforts… Which Asgore already knew since he was once the father of a human child. But he resisted for his plan. 
Another battle started… But not only Asgore, Gaster and the kids were fighting, some other monsters joined ! There was two teams : 
The team that was fighting for peace between humans and monsters (With Troublemaker joining and revealing he has been watching them this whole time… just imagine Undyne and Papyrus’s reaction. Luckily, they didn’t do anything to him since there was more urgent stuff going on at the moment) and Asgore’s team, with Gaster and other monsters who didn’t want humans and monsters to be in peace again, who thought humans were sign of bad luck and sadness… 
Toriel, Philomena and Asriel ended up joining too. Toriel personally confronted Asgore. 
Meanwhile, Troublemaker had to confront his father during this battle, but he couldn’t really tell him anything. It was awkward. Once seen his son as an wanted criminal and one saw his dad changed and completely harmed by his own actions. But before they could do anything… Butterflies appeared. Not a pretty amount of butterflies, it was a scary one. They were glowing and pretty much paralyzed everyone they stopped on. 
Troublemaker, Gaster, Papyrus, Undyne, Alphys, Asgore and the other monsters got paralyzed but somehow, Frisk, Felix and Florian didn’t. 
Then, a silhouette of a human child appeared… Those who knew them immediately recognized them. It was Chara. But they weren’t alone. There were the souls of all the humans kids Asgore killed with them. They were those butterflies who paralyzed everyone. They came back to Chara, who seemed very upset and turned into a butterfly theme boss. 
Chara, alongside all of the human souls, were sad and angry to see that the monsters were still in that stupid conflict, but also because the humans children who fell after Chara all died, killed by Asgore. Chara never wanted that, they didn’t want their death to have caused that. They were really upset, telling monsters and they’re stupid, screaming, crying and attacking because if this pain they have been feeling for years, not being able to rest properly because of this conflict. 
The FFF trio, who were the only ones remaining not paralyzed, had to calm them down. But they also had to speak to group of monsters that had problems with each other, in order to solve them and end this conflict. One of those groups being Gaster, Sans and Papyrus… 
Papyrus got his answers during this talk. Gaster apologized to Sans and told him and despite not trying to bring him back, he still cared about him for all these years. Sure, it didn’t solve everything but it was still better. Sans and Papyrus got reconciled while Sans and Gaster’s relationship remained neutral installed of hate. It was still awkward though. 
The FFF trio also made Toriel, Asriel and Asgore confront. Same thing here, instead of hate, their relationship remained neutral. Asgore was hurt by the news of Toriel being married to Philomena but still accepted it. He even had some affection and sympathy for Felix. 
After these problems solved… All the monsters had to talk with Chara and the other human souls. Seeing everyone apologize had eventually calmed them down as they took their child from again. The butterflies disappeared and Asriel, Sans, Papyrus and Undyne could do their final farewell to their childhood friend, Chara. Toriel and Asgore did it as well, as their adoptive parents. Chara was finally in peace and thanked the FFF trio before finally getting proper rest with the other humans souls, the barrier broke in the process and the monsters were free. 
Some decided to move to the surface and some decided to stay in the underground. Toriel and Philomena moved to the surface with Felix and Frisk as their children, and with Asriel as well of course. Asriel and Frisk were ambassadors of friendship between humans and monsters. Asriel represented the monster as they new leader, letting his old parents retire, and Frisk represented the humans. Felix and Florian helped as well ! 
Troublemaker and Papyrus got closer over time, but his relationship with Gaster was still awkward. Eidothea stayed by Gaster’s side, Undyne and Alphys were happily dating… Mad mew mew became a very popular idol in the surface, Mettaton got popular as well as the fanciest ice-skater in the world… Grillby and Muffet opened a café together, Toriel sometimes allowed kids to come to her house to learn new things despite her old age… Everyone was happy. It was the happy ending. 
•AFTER THE MAIN STORYLINE/As an out!code : 
And after causing troubles at the surface for a while, Troublemaker managed to leave his own AU, to explore the multiverse… Because he has been studying the theory of multiverse alone, this whole time, in secret. He became an out!code and started his trouble making in many AUs, for fun. He will never change… 
But he met many people in his individual journey, such as Snake!Sans, his current best friend and two wonderful children who needed him and didn’t want to leave his side. After wondering what he wanted to do after years of causing troubles, he decided that it was time to calm down. He officially adopted those kids and gave them a better life. He is surprisingly a great father ! He loves his kids more than anything and will definitely introduce them to his family someday. Sure, he still causes troubles but not to them and less frequently. As the smart inventor he is, he created a kind of « miniverse » in a cube-like device, only containing a house and a garden with a tree. This is where he currently lives, peacefully with his kids. 
Oh, and he accidentally created a third kid but still loves him dearly.
 
== Personality ==
Troublemaker is a mischievous but friendly skeleton. He likes causing troubles around him (such as stealing those who deserve it, pranking others, cheating in games…) but can also be very caring. It just depends of your relationship with him. If you’re his friend, he will still be a little teasing but caring ! He’s a very loyal friend and a shoulder you can rest on if you need to. 
He also discovered he had a strong paternal instinct when he adopted his kids. He can be very protective. He doesn’t want them to be involved in the troubles he causes and wants them to have a better life. Sure, he teases them as well, sometimes, they’re not spared but it’s usually in a playful and innocent way and it makes them laugh. He also gave them his stuff from when he was a child. 
As a child, he was very innocent, shy, sweet… He loved picking flowers and play with his favorite bunny plushie (This plushie now belongs to his youngest child, Hope), but his innocent nature faded as he grew up. As a teenager, he was already causing troubles and was emotionally pretty unstable. 
== Appearance ==
Troublemaker is a short skeleton with dark circles under his eye sockets (Probably because he drinks too much coffee and lacks of sleep) and different colored pupils, his left pupil is green while the right one is yellow. His face is often dirty since he spends almost all of his time working, causing troubles outside or escaping from the guards… 
He wears brown and green googles on this head (And on his face when he's working), a multicolored baggy turtle-neck, a broken overall, and brown belt, brown gloves, brown boots and a dark blue jacket.
His teeth seem to be yellowish (Again, probably because of coffee) and the inside of his "nose" seems to be dark green. He also blushes dark green.
He sometimes wears a green turtleneck instead of the rainbow one his adoptive mothers made him.
== Abilities ==
Troublemaker isn't strong, he's even pretty weak, which is why he builds so much weapons and devices… But he's very good a dodging, getting away, escaping and is pretty fast ! He's also very good to steal without people even feel his touch. That man can be sneaky if needed.
His science and technology skills allow him to invent many devices and machines he can use as weapons, one being a special gun with a special source of energy that allows him to travel between universes for a limited amount of time. He must always have extra sources of energy because he would remain stuck where he is if the teleporting Gun ever runs out of energy. 
=== •Weapons : ===
•Troublemaker has a metal-looking Gaster Blaster. He rarely uses it but seems damaged and dirty. Its attacks look lime green and electrical. He also has bones attacks but again, he’s just not using them much. 
•Troublemaker also has a teleporting gun he uses to travel between AUs but also to attack. It can't kill but is very similar to a taser, but stronger. It has two buttons : 
- Red = attack mode, it's like a taser but more powerful. 
-Green = Travel/portal mode. A screen appears on the top of the gun when he presses that button and the code of the selected localization appears on the black bone on the side of the gun. 
 
== Relationships ==
•IN HIS AU : 
•Marutale!Gaster : Troublemaker has a kinda awkward relationship with his father, because of what happened between them. He doesn’t even call him « dad » or « father », he’s rather call him « old man » or just by his name. But as a kid and teenager, even though he was disgusted by his father’s actions, he actually missed him and wished it never happened. He wished they could keep the relationship they had before Chara’s death. The most difficult period was his teenage years, he because very angry and emotionally unstable but Philomena always managed to calm him down. 
as an adult, when Gaster asked him why he didn’t think they could get the relationship they used to have back, he answered « I needed you 20 years ago, not now. » and at the end of the story, their relationship remained neutral. He doesn’t hate him anymore but still doesn’t love him as much as he did as a kid. 
•Marutale!Papyrus : After the events of the main story, his relationship with his Papyrus got better but Papyrus is still annoyed when Troublemaker causes troubles. He scolds him, just like Classic!Papyrus scolds Classic!Sans when he makes puns. 
But in the past, just like Undyne, he wanted to arrest him. 
Despite not being able to grow up with him, as an adult, Troublemaker had his own ways of checking if his Papyrus was okay, even though he knew that he wanted to arrest him. It didn’t stop him from making sure that his little brother was okay. He even liked teasing him ! Their relationship got better after the story. 
•Marutale!Toriel : He respects Toriel and saw her as a second mother figure when he was younger, even though he wasn’t the best at showing it. She initially was like a teacher to him, she used to help him learning how to write, read, calculate… When Gaster was busy. She is also the one who thought him many puns and jokes when he was a child ! She used to pull very harmless prank on him, Chara, Asriel and Undyne. He used to say that it was like having a very tall and strong best friend. 
He wasn’t against her marriage with Philomena, his actual adoptive mother. But since she already was pretty teasing towards Sans, she used to joke about it and say something like « How does this feel to know that I married your mother? »… 
… Which always made him cringe but since it was the purpose, she always bursted out laughing. Toriel loved teasing little Sans and Asriel, she also loved making them laugh, just like any good mother loves to see her children happy. 
When he was a teenager, Toriel always had to send guards to bring him back home. She always tried to help him, to understand why he was causing so much troubles… He didn’t know how to respond to her affection but she didn’t care about that. 
Now, as an adult, he still sees her sometimes and teases her. He calls her « old lady », or « granny » (Which technically isn’t wrong since he adopted kids) and they have puns battle sometimes, despite this version of Toriel being very old now since she didn’t stop aging in this AU. 
•Marutale!Asriel : Asriel initially was his childhood friend. They had a little friend group with little Undyne and Chara back then since their parents were friends. 
But after the events of the past, he started to live with him as Philomena’s adopted son and after Toriel and Philomena’s engagement they became step-brothers. They were very happy about that and pretty much grew up together. Asriel was a bit of a troublemaker too when he was younger but he stopped, while Sans didn’t. 
When Asriel took Toriel’s succession, Troublemaker teased him, calling him « your majesty » in a sarcastic way. 
•Philomena : Philomena was always very sweet and gentle towards little Sans and the other kids of their former little groups. Since he was innocent and easily scared back then, he used to hide behind her when Undyne pretended to be a dangerous shark in their games… 
So no wonder why she’s the one he ran to when he escaped after what happened with his Gaster. Ever since, she took care of him and treated him as her own son, even though, as time went by, he became more difficult to handle (Especially in his teenage years-) 
He was very happy for her when she married Toriel. Just like pretty much everyone in Toriel’s kingdom, everyone knew it was going to happen, they didn’t hide it pretty well. He was also glad Toriel found happiness again and saw them as two mother figures, even though he never really knew how to tell them how much they mean to him. It was still easier for him to show affection to Philomena, as he sometimes fell asleep on her shoulder, accepted her hugs… She was the only one he managed to tell how the felt about everything in his childhood and teenage years. 
He loves his adoptive mother a whole lot and would always be ready to defend her if needed ! 
•Felix : Troublemaker was also happy when Felix was born, but just like any mischievous person, he teased him in a friendly way. That’s what big bros do after all. 
He kept an eye on Felix, alongside his friends Frisk and Florian during the main story, to make sure nothing bad happens. He saw they were doing pretty well and decided to only bring them back in case they end up in BIG troubles, which didn’t happen and at the end, everything went well. He’s very proud of little Felix. 
•Marutale!Frisk : At first, he didn’t really pay attention to Frisk since they were just another fallen human. He thought it was going to be the same over and over again, them leaving the Toriel’s kingdom then dying. But it didn’t happen and he was impressed. He got some kind of affection for this kid and started to tease them as well. He’s happy he got to meet them, the savior of the entire underground. Everything got better thanks to them and he’s very thankful. 
•Florian/Marutale!Monster kid :He likes Florian’s grumpy nature, it makes them easy to tease, and their reactions are funny to him. 
•Marutale!Chara : Chara was his childhood friend, alongside Asriel and Undyne. Saying his final farewell to them left a bittersweet aftertaste to him, and a feeling of nostalgia. 
•Marutale!Undyne : Undyne was also his childhood friend. When they were little, Undyne was very energetic and used to chase him, pretending she was a shark and she was going to eat him raw, which scared him. But they were still friends. 
Since Undyne became Asgore’s Royal guard and Troublemaker caused troubles in Asgore’s kingdom, she tried to arrest him several times. Even after the story, they still keep a friendly rivalry. 
•Marutale!Alphys : They didn’t really interact much but they share interests in machines and robots. They sometimes meet and talk about their inventions. Undyne calls them the « nerd duo ». 
•Marutale!Asgore : Just like with Gaster, their relationship is pretty awkward. He used to admire him when he was little and Asgore allowed him to see his beautiful Garden full of flowers… But this admiration disappeared with the events of the main story. 
•Eidothea : Eidothea flirts a lot with his father… So when Gaster created him, she saw him a lot was completely in fond of him. According to her, he was an adorable baby and child and looked a lot like his father. 
•Marutale!Grillby, Marutale!Muffet and Marutale!Mettaton : He seems to be friend with them. Especially with Grillby. He teases him a lot as well, trying to get him out of his «serious guy » role. He also helped him asking Muffet out. 
•Mister Pudding : «*Uhhh… What? » 
•OUTSIDE OF HIS AU : 
•Ink!Sans : Ink doesn’t really like Troublemaker, since he causes Troubles in AUs he’s not supposed to be in. But he ended up forgetting about him… You know, because Ink he’s very forgetful. 
•Snake!Sans : Snake is Troublemaker’s best friend. Snake hates his job and gives weapons and materials to Troublemaker, just to annoy his superiors. Troublemaker also sometimes teases Snake because of his grumpy nature, just like he did with little Florian. Snake’s reaction are pretty funny to him. They’re also partners in crimes sometimes when it comes to causing troubles together. They insult each other but in a playful way, it’s their way of saying « I care about you » and he also knows his kids. Snake also had to help Troublemaker escaping prison many times… 
Troublemaker and Snake actually met in the prison of Snake’s universe. They escaped together and they became friends! 
•Ray, Raven and Hope : Let’s get it straight. Troublemaker LOVES his children. They’re very precious to him. He wants them to have a better life and would gladly give his own life for them. He currently lives with them in an isolated place and tries his best to be a good father. He didn’t think he would ever have children and had no idea he had a paternal instinct before having them, but he doesn’t regret anything and is proud of his sons. When no one is looking, he can be much softer with them, as if the «Dad-mode » was activated. 
•Valentina (OC) : Once when he was a teenager and still studying the theory in multiverse in secret, he made ONE attempt of traveling and ended up in a random AU, where he met a skeleton lady. She seemed sad… But his bratty nature made her smile. He was a lost kid trying to go home after an experiment. She told him how unhappy she was of her marriage and they kept each other company for a few days. But one day, she didn’t come. She never came back, and he managed to find a way home. He never knew what happened to his old friend… He isn’t aware of her terrible fate… Her own husband killer her. Once he came back, Toriel and Philomena were worried sick because he went missing for a few days. He never told them where he was and didn’t attempt to travel again until the end of the main story line, many, many years later. 
•Baker!Blueberry!Sans : Blueberry is a young baker in a place where Troublemaker often goes. He treats him like a nephew and often teases him as well. He absolutely loves his pastries, they’re his favorites. 
Blueberry also reminds him of Valentina, his old friend he haven’t seen in years. If only he knew this young baker was her son… 
(NOTE : Baker!Blueberry!Sans isn’t related in any way to Fanon!Swap!Sans. He’s basically a Sans OC based on actual blueberries. You can call him Myrtille!Sans to avoid confusions if you want.) 
* Extra : Here is his messy and chaotic family tree (With alternate versions of Noelle and Rudy from Deltarune, because I didn't want Asgore to end up all alone) :

== Trivia ==
* Troublemaker was heavily inspired by Rick Sanchez (From Rick and Morty, for the teleporting gun) and Eda Clawthorne (From The owl house, for his personality). His Jacket was also inspired by Alador Blight's Jacket (The owl house).
* His rainbow turtleneck was a present from his mothers, they hated seeing him wearing damaged clothes so they decided to make a new shirt… However, they couldn’t pick a color and ended up using all of their yarns. They were embarrassed about it and told Troublemaker that he didn’t have to wear it if he hated it. But the situation made him burst into laughter, and since he loves his mothers so much, he actually accepted to wear it. It has a sentimental value to him.
* He's a coffee lover. He also has alcohol in his pockets but doesn't drink in front of his kids.
* He nicknames his kids "the munchkins".
* The jacket he's currently wearing once belonged to Marutale!Gaster. He stole it from him and keeps him as a trophy.
* His MBTI is INTP.
* He collects his own "wanted posters" he finds when he's outside. He also doesn't like being called "Sans" anymore, he'd rather be called "Troublemaker", which is the name that is usually written on them, except on the ones from Marutale.
* He realized how big the multiverse was and how small he was. This made him see everything around him differently and feel the overview effect…He also doesn't like big spaces and huge buildings but can still act calm when he has to confront this fear.
* He is also afraid of bees, wasps and anything similar.
*Troublemaker has a little robotic dog named « Milo ». His kids were the ones picking the dog’s name. He loves dogs !
*This guy definetly owns a #1 dad mug, and it’s a present from his kids. It’s his favorite mug. 
*He has a fresh design…
*He has a coffee themed pyjama. He’s also NOT a morning person. 
*He secretely enjoys singing... His favorite music genre is rock. He probably listens to Muse songs. His favorite song would be Knights of Cynodia.
*His AU takes place in the UK, which makes him British.
*Alongside English, he can also speak French. He also knows Morse code and binary language ! 
*You can talk to him on C.Ai here !
