4.0tale is a cyber-music Undertale AU centered around Sans, who was originally nothing more than a lazy gamer and talented hacker living in Snowdin. He only became a DJ because of his younger brother, Papyrus, a charismatic rapper who pulled him onto the stage and gave him a reason to connect with the world. Everything changed after countless RESETs and Genocide timelines caused by the Player. Watching Papyrus die over and over again broke Sans completely. Knowing he could never defeat the Player through normal means, he turned to the AU’s forbidden power: "AI" (an entity with near-absolute control over the game’s system), capable of granting immense knowledge and manipulating reality itself. After obtaining AI, Sans became Techno. Unlike many versions of Sans, Techno does not hate Frisk. He understands that Frisk is merely a character being controlled by someone beyond the screen. His hatred is directed toward the Player ("us"). Using AI, Techno seizes control of the game itself, locking choices, denying freedom, and preventing the Player from doing whatever they want. His ultimate goal is not to destroy the Underground, but to break through the boundary of the game and reach the one responsible for the endless cycle of suffering. 4.0tale, the true battle is not between Frisk and Sans. It is between a character who became aware of his own fiction and the person holding the controls.
In Underverse
✜»✜«✜»✜«✜»✜«✜»✜
- Techno first learned about the existence of other AUs when Nightmare visited 4.0Tale in an attempt to recruit him into his faction. However, Techno had no interest in joining anyone's side and immediately rejected the offer. Even so, the encounter sparked his curiosity. If other worlds truly existed beyond his own, then there had to be a way to reach them.
- Driven by that curiosity, Techno began experimenting with the forbidden ability "AI" alongside his own hacking skills. After countless attempts, he eventually succeeded in breaking through the boundaries of 4.0Tale, allowing himself to freely travel between alternate universes. Rather than pursuing any grand objective, he wandered the multiverse simply because he found it interesting.
- During one of these journeys, Techno encountered Error. Fascinated by Error's corrupted existence, he secretly began "repairing" him, treating the process as nothing more than another experiment to satisfy his curiosity.
- After some time, Ink noticed that Error had started behaving strangely. Unable to determine the cause, he asked the others to investigate. Fresh eventually tracked the source of the problem after being guided there by the "Audience", leading him directly to Techno's privately programmed dimension.
- Their first meeting immediately turned hostile. Techno was genuinely surprised that Fresh had managed to enter a space that was supposed to be accessible only to himself. To Techno, Fresh was interfering with an experiment he had been enjoying. Meanwhile, Fresh saw Techno as the reason behind Error's unusual behavior and viewed stopping him as part of his responsibility to the "Audience".
- The two quickly engaged in battle. However, despite fighting with everything they had, neither side was able to gain a decisive advantage. Their abilities and adaptability were so evenly matched that the battle reached a complete stalemate. Realizing that continuing to fight would accomplish nothing, both agreed to stop and settle the situation through conversation instead.
- During their discussion, Techno discovered something that immediately caught his attention: Fresh possessed the ability to break the fourth wall ( the very thing Techno had been searching for ever since becoming aware of the truth behind his own world).
- Seeing an opportunity, Techno proposed a deal. If Fresh agreed to help him one day escape beyond the boundaries of the game and into the world outside the screen, Techno would immediately stop "repairing" Error and leave him alone. Fresh accepted the proposal, though with one condition, the time wasn't right yet.
- As their conversation continued, the two realized they actually had something else in common. Beyond their own personal goals, both simply enjoyed having fun and chasing whatever interested them. That unexpected similarity completely changed the atmosphere between them. Instead of remaining enemies, they called a truce and acted as though their battle had never happened.
- In the present day, Techno has largely abandoned the experiments that once consumed him and now spends most of his time relaxing after everything he has been through. Fresh, however, still visits him from time to time whenever his own side encounters problems too difficult to solve alone, often relying on Techno's intelligence and hacking abilities to deal with situations beyond anyone else's capabilities.
About Techno!Sans personality
✜»✜«✜»✜«✜»✜«✜»✜
Techno is extremely arrogant, having complete confidence in both his intelligence and his abilities. He rarely believes anyone can outsmart or overpower him. Although he usually appears calm and playful, he can become surprisingly manic whenever something genuinely captures his curiosity, often throwing himself into experiments without caring about the consequences.
Likes:
- Cheese, especially pizza.
- Cats ( His favorite animals).
- Rap music, largely because Papyrus was a rapper.
- Video games, as he was originally a gamer long before becoming a DJ.
- Whenever he's bored, he likes chewing bubble gum made from his own holograms.
Dislikes:
- Being interrupted while working or experimenting.
- Sports, which he finds boring.
- Insects and parasites ( get it? He's a gamer and also a hacker... And he HATE "bug" hehe)
- "player"...
- Any food or anything related to octopuses.
Fears:
- Despite his confidence, Techno has a genuine fear of tentacles. Because of this, he dislikes octopuses as well as monsters or Sans variants that possess tentacles, such as Nightmare ( This fear is also one of the reasons why he rejected Nightmare's invitation in the first place).
Abilities
✜»✜«✜»✜«✜»✜«✜»✜
- Techno can freely travel between AUs using his hacking abilities. He is also capable of editing an AU's code, allowing him to add, remove, or alter parts of its programming.
- He can create solid pink holograms that function as real objects and is even able to generate holographic clone of other characters and himself.
- Thanks to the forbidden ability "AI," Techno possesses extraordinary intelligence, allowing him to rapidly analyze situations and predict countless possibilities. He can also "Hack" his offensive and defensive capabilities in to "high level", he is considered one of the strongest beings in the Underverse.
- Because of his overwhelming power, Techno is often regarded as an "optional hidden boss" within the Underverse. Luckly, he has no true enemies there ( at most, there are simply individuals he doesn't get along with).
Weaknesses:
- Despite his strength, Techno has several limitations. His code deletion abilities only work properly on game-based characters. They cannot be used directly on beings such as Ink or Fresh, whose existences aren't tied to standard game code.
- Against unique entities like Error or Fatal, Techno must first locate and understand their "code" before he can manipulate or "erase" it ( that's why he was almost kill Error because of his curiosity...).
- Additionally, overusing the forbidden ability "AI" places immense strain on his body and mind, eventually causing severe exhaustion.
- Papyrus...
Fun Facts:
✜»✜«✜»✜«✜»✜«✜»✜
- Techno is Aro/Pan
- Birthday 25/05
- Y'all can freely ship him with anyone even OCs.
- Although Techno is extremely intelligent and cautious, if someone invites him to do something interesting enough, he'll be surprisingly easy to talk into it, especially when he's bored.
- Techno sometimes cries for no apparent reason. Deep down, he's feeling sad without realizing it, because he's forgotten what that emotion feels like.
- Techno gets very awkward around people with small, adorable appearances. To him, they seem like clueless little kids, which makes him embarrassingly easy to fluster around them ( you could say that Techno sees cute things as completely innocent and impossible to predict) Ah, and Techno also can't deal with people who are just too dumb.
- When he's exhausted, Techno heats up like an overheating electronic device, so he often takes off his jacket to cool down.
Relationship:
✜»✜«✜»✜«✜»✜«✜»✜
Fresh Sans:
- First, I'll split Techno and Fresh Sans's relationship in Underverse into two versions: canon and fanon.
Canon:
- Techno and Fresh don't have any romantic feelings for each other. They aren't particularly fond of one another either, though neither of them makes it obvious. Their relationship is based solely on a mutual agreement to pursue a shared goal: fun. Fresh is the only one capable of entering Techno's personal space thanks to his ability to break the fourth wall, so he occasionally drops by to ask Techno to help the protagonists.
Fanon: or different AU
- good friends, they enjoy looking for fun together.
- If it's a toxic ship, I like portraying Fresh as the possessive, controlling one, while Techno is the one yearning for love.
- If it's a healthy ship, then the two start out as friends before gradually becoming lovers. Fresh openly has feelings for Techno, while Techno, despite always looking annoyed, secretly likes Fresh just as much.
Error Sans:
- Error absolutely hates Techno because he nearly "fixed" him once. As for Techno, he occasionally likes to tease Error whenever they happen to cross paths.
Ink Sans:
- Techno doesn't like the fact that Ink is helping "them", but he doesn't hold anything against Ink as a person. In fact, Techno finds Ink quite interesting.
Dream Sans:
- Techno doesn't think there's anything particularly special about Dream.
Swap Sans:
- Techno always sees a reflection of his brother Papyrus in every Swap Sans. Because of that, he tends to be especially gentle with them and usually avoids unnecessary conflict.
i thought the goggles on the head in your pfp were eyes like cappy from super mario odyssey, this would imply the hair can be thrown leaving a bald head in its wake
Wha-😭 i was cosplaying Thadeus from "Killer Peter" LOL
what her character is like to her other siblings and what they think of her? Are they siscons or just ordinary sibling affection? and how do the 'parents' behave and think about their daughter?
(Sorry for the amount of questions, I just admire her character too much!)
A little summary about Alpha!! She’s the second child, and she’s got a pretty crazy and stubborn personality lmao(Yandere vibe type shi-).
When it comes to her older brother Prototype, he does genuinely care about her, but he can get REALLY annoyed by some of her "bad behavior" sometimes. Beta, on the other hand, is absolutely terrified of Alpha 😭 She’s always messing with him because of how shy and timid he is. As for the youngest, "Rose", it pretty much just sees Alpha as their older sister.
To Techno, both Alpha and Beta are basically successful results of his experiments(not really successful but he does care for them tho). Meanwhile, Fresh can sometimes be a little creeped out by the way Alpha thinks, but he’s still super supportive of her and tends to spoil her a LOT.
And I got another question for Techno: how does he feel about all those outcodes roaming through Omniverse?
Since he doesn't like glitches, but again, not all outcodes are glitches. Some of them were created to be outcodes from the start.
So, me just being curious 🤭🤔
His real enemy is "us"(the players/viewers controlling the game) So when it comes to outcodes, he doesn't hate them or pay much attention to them. If someone is interesting enough, Techno might take notice and approach them. Otherwise, he simply couldn't care less.
Bonus: If you want Techno to actually hate you, there are only two ways: either keep bothering him, or threaten him by trying to harm or kill him...
