What if: Glitchtale\Multiverse

Final Reckoning of HATE. Quest for Emeralds. God vs Devil.

Asriel Dreemuur: Chara, it's me your best friend. ASRIEL DREEMUUR. Chara saw her best friend in shape of goat his true form not only that, but he is now in his godly state achieved, when he absorbs all seven souls. It makes him possess incredible god-like power. More like infinite. However Chara knew this might happen so she prepared. 

Chara: Well traitor it seems you have another glitch. Frisk gave you her soul, when she was still alive. However let's not fret over this. I have something Asriel. I know I can't fight you with my current power, it's not nearly enough. But this gems. Seven Chaos Emeralds float behind her. 

Chara: They will give me so much power. No one ever dreams about. I learned and studied legends about legendary artefacts called Chaos Emeralds. They have limitless energy and power to do wonders and miracles. They have this power. I discovered you can use it, if you know how to. I now have power just to do that with my determination and them. I will erase this world from existence. 

Chara told her plan her friends. She then closed her eyes emeralds glowed giving her power. She screamed creating massive ball surronding her and Asriel. She turned completely black like her hate completely absorbed her and she will never return. This is HATE Chara. Emeralds float away in unknown direction within underground. Even Chara did not know their location, but she did not have to. She had enough power. 

HATE Chara: Finally I have power, so much it's almost overwhelming. I have this here Asriel. She says, while creating ERASE button. Obvious what it does. She had power to create, but couldn't use it herself. Someone else had to help.

Hate Chara: You see I can't activate this button that will erase this timeline from existence. No more pain or sufforing. No more lies told. No more agony or inprisoment for monsters. You know that I hate humanity with burning passion. Frisk I trusted her. However she betrayed me just like you. However she does not matter. She did horrible things, but so have you. So what will it be, Asriel? 

Asriel Dreemuur: Sorry Chara. But erase was never an option. I forgive Frisk, I will make you see. He said with confidence. He managed to destroy the button. He did not have idea about how powerful Chara became after those emeralds, but he won't give up. 

HATE Chara: Well I wanted this to happen easily. Oh well Asriel you are the only obsticle without you, I will be able to erase timeline without your help. She proclaimed. While rushing at Asriel engaging him in battle. 

Meanwhile outside. 

Sans finally recovered from using his Dark Form. However he saw multy-colored beams od light going into different directions. He sensed chaos energy or Chaos Emeralds energy nearby, he realized that Chara must have used them for more power. It's terrible in their situation. He needs to gather emeralds as fast as possible, due to Chara there is weird monsters appearing in all of underground. 

Sans was able to blast through them using his mobility and strength to his advantage. he managed to collect half of Emeralds by this method. However the more time he took to gather his things. The stronger his enemies were growing. He needed to be quick like he always are. That's why he needed to be even faster. He used all of his speed to be as fast as possible.

Asriel's Pov

Asriel fough with Chara. Unexpectedly, but her power that she gained from Emeralds is enough to match him. Well at least in most things. Chara had enough power to hurt Asriel, but even now he was able to push her. He was truly powerful opponent for Chara, even with power of the Emeralds. Asriel too had his power from souls. Both pacifist and genocide met each other to see, which would prevail and what will perish. Chara created multiple orbs of pure energy to make Asrile pay. He countered with his stars that he loved to use. He used attacks that he and Chara invented. It affected Chara, alas not entirely. Asriel was not able to make Chara see things through.
