Maniac!sans

ORIGIN: One day in Snowdin sans went into the back door in his house,like he had done many times before. But this time he could feel something was off. He felt that something or someone was watching him. Then he realised that Gaster was in the room with him but he felt that he had seen this before. Gaster went up to Sans and told him that he wanted to make him an offer. But before he explained anything about it he explained that the human were not as nice as they seemed and that they had completed many genocide routes before this moment. Gaster told Sans that he wasn't "determined" enough but he could help with that. He pulled out a syringe with a strange substance in it. He said that he could make Sans more determined but it would cost him his sanity. Sans didn't want to accept at first,but when he thought about seeing all his friends die again. He accepted the offer. Once he had the determination to stop the human set out to find them. Meanwhile Frisk was coming to the end of snowdin like many times before. When they got to the final area they were expecting to find Papyrus at the end but this time something else happened. They found Sans at the end of the room. He greeted them saying how he remembered the times they killed his brother over and over and over. But then something changed. Originally he was going to fulfil Papyrus'es dream by capturing Frisk but he decided that wasn't enough. He was going to kill them on the spot. So what he did was he summoned a cage of blue bones around Frisk,commenting how he could just leave them there to starve but then he summoned a ring of gaster blasters before saying "when i said you were going to have a bad time... I WASN'T KIDDING" before firing at the human. When there was nothing left he didn't feel satisfied. He knew they would just come back. So he went back to his house and waited for them. When they "respawned" Sans didn't hesitate to stab them with his bones. Then he realised this wasn't like him,that he shouldn't be doing this. But he didn't care. Over the next few days he would wait for Frisk to come back to him. And he would kill them no matter what. The more he did this,the more he lost his sanity. And the more annoyed Frisk became. Eventually Flowey took notice of Sans'es questionable tactics and went up to him. He asked why Sans was doing this. He replied with "Just a bit of fun". He then asked Flowey to step away from him. When he refused Sans imapaled him with his now strangely spikey bones. But then Frisk didn't respawn,they had given up. Moved on if you will. Sans was disappointed as he felt that they hadn't learned their lesson (even though with Sans'es method wouldn't let them) and he felt that he needed to be MORE powerful in case they came back. And so he went on a killing spree in order to harvest LV believing it was for a good cause. No one was safe from him. Toriel,undyne. Not even his brother was safe from his wrath. Eventually he got to king Asgore but this time Sans didn't kill him. Instead he made him a deal. He would spare Asgore if he gave him the 6 human souls. Asgore refused leading to Sans decapitating him and placing his head on a spike. After this sans went back to the ruins and waited for Someone,anyone to come into the underground. But nobody came...
Now Sans wanders around the ruins waiting for a human or anything really to come down into the underground. With bloodshot eyes,the top part of his skull missing and a chainsaw. If anyone sees him... they better run
PERSONALITY: Maniac!Sans'es personality is essentialy a combination of insanity!sans'es personality and underfell sans'es personality. Hes a complete killing maniac but when he's not focused on murder (almost never) he's a complete a**hole as he feels he is immortal with both his L.O.V.E and his determination. (He also hates the mention of E.X.P for some reason)
RELATIONSHIPS: Maniac!Sans has absolutley no friends at all. Everyone he meets (even some of the evil sans'es) finds him revolting. This also pushes his sanity to the breaking point as he has no one to help him. He has considered asking ink sans for help before deciding thats a bad idea by saying "i dont need to ask some random inferior version of me. I can help myself =]) However he seems to have an interest in Dust sans as he believes that they have been through his pain. {he also hates the mention of any good sans for example ink,alpha,blueberry. Any good sans he hears about he will hate their guts.)
ABILITIES: While maniac!sans doesn't have many abilities as he mostly uses his chainsaw,he still has a few abilities that you should definitly avoid. For starters he has the spike bone throw. When activated he will summon 10 spikey bones that shoot forward. While each bone only does 4 damage per bone, he likes to use this move a lot so get used to it. Next is the Maniac Blaster.This gaster blaster is twice the size of a regular blaster and does twice the damage,however it does have a delay between summoning and firing. After that is his chainsaw. When he swings at you,be prepared as each hit does 20 damage. And it can sometimes turn blue or orange so be careful. Finnaly is his "rage" ability.When he reaches half health [For clarification he has 250 health] he will activate this ability causing him to buff up his damage to twice the normal amount.
þħáßé ³: Not much is known about this phase but it is said this phase will activate when Maniac!Sans obtains the human souls. Something he is determined to do no matter what the cost is. However it is said that when he does,he will gain control of about half of all the aus in the multiverse.While Maniac!sans doesn't say he is interested in this. Deep down it is his only goal.
DIALOGUE: (when falling down for the first time) "... Well,well,well. It's been some time since YOU'VE been down here. I gotta say it's been pretty lonely.You can agree right? heh. Why would you? You dont know what iv'e been through,what iv'e had to do. So go ahead.Continue. Il see you later. þáł." (after exiting the ruins) "Feels weird doesn't it? Well that's how it's been for some time now. At least ever since Frisk stopped respawning. But they were different to you.After all. . íŧß níçé ŧó ħá“é ßóµé đ¶éßħ µéáŧ." (After reaching the end of snowdin.) "well this is the spot. This is where i started the killing spree... And this is where im going to continue it!" [initiate battle sequence] Throught the fight sans will mention how he remembers this feeling but plays it off to just being his insanity.
