What if: Glitchtale\Multiverse

New Path?

Sans now was trying to summon his Gaster Blaster. Due to his experience with his new found power, he was able to summon it earlier than his bones. It looked same as bones save it had same eye sockets(flashing eye) as him. Sans prepared to launch Gb at ground, but he also created bones in hopes that they will absorb most of impact. Gb opened it mounth and charged it's beam. It fired at another location to not leave more damage to already damaged area. After collision with ground. A huge explosion was emitted from GB engolving Sans and quite huge chunck of forest. Then only that was seen is Sans. He is unharmed, but on the other hand area that he fired his gb at was no more with huge part of forest. Luckily it was remote location. So no one should know about it, nor see his damage. 

It did not hit Sans like bones. He was especting it. Still he was surprised by his power. It seemed insanely powerful. He felt he can get stronger than right now. Due to any organism capability to grow stronger. However this leaves question on his new abilities. He already saw his new shoes, which supposingly helped him with his speed and were durable, via fact that they easily withstood Sans hyper sonic speed. Sans was thinking on how to bring his new powers into light. When he got urge to curl himself into a ball and go into a tree. Sans thought this at stupid, but decided to try anyways. 

It wouldn't hurt. Sans mused. He easily did so. He started to move spining on his ball like state. He rushed at tree. Yes it's famous homing attack(if I am not wrong). He hit tree, which exploded by impact with Sans spin with homing attack. Sans stood in his normal state. He found out one of his new powers. He can spin and also go to weak point of tree, which he could notice. He called his ability to go ball and spin. Spin attack, while other is called Homing Attack. 

Sans: I wonder what else can I do?

Time skip

A couple of months passed from Sans transformation and his power change. Of course his brother was worried for Sans. He had Alphys to examine him, but she did not see anything wrong with him. She only said that he had immense amount of energy, that's it. She stated that it seemed to not be harmful. That made Papyrus and others to calm. Sans continued to train all this time. 

He was able to master all of abilities and powers he got. Note: Basically can do anything Sonic do, but it's stronger and faster and on top of it all add his own abilities amplified by Sonic abilities. 

Moreover he grew more powerful this months because of his training. Also he noticed that he was getting stronger even without training. Also Frisk already have fallen into underground. She was experimenting with her power. The power of reset. This power allows user to control time itself. Reseting this world and timeline. Sans was immune to this as he was able to remember everything. Now he was waiting for something to happen. 

Little did he know what adventures await for him. So let's skip genocide as it's current  Frisk path. 

Judgement Hall

A pair of footsteps is heard. In the corridor right in centre of it. A figure. A short one is there. It's a skeleton. Not normal one though. It Sans the Skeleton. Also for some reason he also likes to call himself Sonic sometimes. He does not know why. Anyways he was waiting for Frisk. He did not know why he hadn't stopped her in the beggining. However he just couldn't force himself to break old lady promise early on. Only when his brother was killed he was too angry to kept that promise. 

Although Frisk killed even Old Lady. He knew that too. He wondered why such sweet kid would do something like this. Alas he did not know of another kid forcing her. Puppetering genocide with her hate and power. 

After time. A small figure even shorter than Sans is entered the hall. It was none other than Frisk. The kid whose had power to alter this world, whoever she wished. Meanwhile Chara first fallen kid who planned on freeing monsters. Encouraged her to do this route. Genocide. Frisk did not see anything freeing. Perhaps in Pacifist. Despite it her curiosity got better of her. She did it to see what differences will be. She saw them, but did not like what she saw.
