Aftertale Geno is a Sans who was able to survive a Genocide timeline by escaping to the Save screen after being slashed by a genocidal Frisk. He now refers to himself by the name "Geno", a title he took due to his regret in failing to save his original timeline from genocide. He is stuck at the save screen with Frisk due to his mortal wound. Geno wants to completely destroy the universe, seeing it as the only way to end Papyrus's repeated deaths, but as he cannot leave the Save screen due to his minimal hp, he tries to get the other Sans to do it. If they continually disagree, then he will erase his mind and will start over again. During the events of Aftertale, he stopped doing this so that the current Sans will remember all the resets and Genocide routes in the previous timelines in hopes to get him on his side.

Geno "survived" the Genocide timeline by injecting himself with determination, and before dusting away due to Frisk's attack, he escapes outside the timeline to the Save Screen, where he resides.

After having endured countless resets and failures, his own inability to fix the situation and Sans' continued nihilism got to him, and he decided the only way in which to save his friends and family from the human's torment was by ending the timeline. He planned to do this by either convincing or tricking Sans into bring the human into the Save Screen, upon which he would then enter the timeline himself, and having more determination than Flowey, he would have control over the timeline, allowing him to erase it "to protect Papyrus".

Geno is very manipulative and will continue to manipulate Sans to gain his trust after erasing his mind over and over until he finally gets his way.

He blames both Chara and Frisk for the genocide runs and calls them "his murderer". He is desperate to convince the current Sans to follow his plan, even if he has to use force.

He is also very sensitive about Papyrus and will not let anyone touch his scarf. When Sans brings Papyrus with him on his visit to the Save screen, Geno becomes furious.

While he can be quite violent, he still has a sense of humour, and his first reaction to seeing Sans is to make puns.

The reasons for Geno's drastic change in morality and judgement is due to his isolation, his mere fraction of a soul, and the determination reinforcing his will to continue.

Like the original Sans, Geno has an unzipped hoodie jacket with a white shirt underneath, along with shorts and fluffy slippers. However, he has some differences to classic Sans. Geno's jacket and slipper are completely white, he has a huge bloody gash that he got after being hit in the Genocide run, along with blood coming from his mouth, and some having dropped onto his slippers. He wears his Papyrus' scarf, which he is very protective of, treating it as if it was Papyrus. He is seen with white glitchy particles around him, one of which is covering his right eye socket, which he can control. Geno Sans placed those particles there on purpose to hide the part of his skull that's melting off due to injecting himself with Determination. He does this to ensure that Sans and Frisk would not be frightened by his ghastly appearance.

Geno has all of Undertale Sans' attacks and abilities, including Bones, Blasters, and teleporting. He can bring others into the save screen, but seemingly only when they are making physical contact with Sans, who is his anchor to the timeline. Due to his location in the Save screen, he is unaffected by resets or the passage of time. It's unclear if this is due to an external factor or a new ability, but Geno can control glitches around his body, primarily to hide his melted skull. With his large amount of Determination, he can remember reset and erase the timeline if he is inside it, with his DT overpowering Flowey's, coming short of Frisk/Chara's however.

You're dead, or at least, you should be. What is this place?
