THE END

???

"Oh? Only one? Forgot about me already I see."

Frisk

I turned around as fast as I could and barely put up my barrier in time as a blast was deflected off of it and back at the attacker, a skull much like Sans's was destroyed, "oh? You've improved, that's good.. I need your soul to be nice and strong, when I take it from you!" The tall skeleton said as he raised his palm, it glowed purple, remembering our last fight I avoided this one rolling out of the way and pulling Sans and Undyne from the acidic drops with my barrier, "what are you doing Gaster? How did you get out of the void, what do you want with my soul?!"

Gaster

"I'm only trying to kill you so I can take your soul, you wouldn't have it in a few more moments anyways.. As for that dreadful void, I found my way out of there by absorbing the power of your dear friend Blook, oh but don't worry, he's very much alive and well.. For a ghost that is. Ah yes what do I want with your soul, you ask? Well since you haven't realized how utterly powerful you can be yet, I must take that power from you and use it to destroy the surface world and all humans left on it, once that's done I'll create a paradise for all monster kind to live in, with no humans to threaten or enslave us ever again."

Sans

"I'll never let the happen, Gaster!" I yelled as I summoned my own skull, the timer was 1, and if I could get up to 10 of them, then I could beat him.. "Oh please put away that trivial toy, you couldn't beat me then, and you most definitely could never beat me now, who taught you how to control your magic anyways, son?" His response chilled me to the bone, no pun intended, but I wasn't ready to just give him the kids soul just like that, no I had to protect them, they were gonna be our saviour, all Gaster wants to be is a liberator.

Undyne

"Hey don't forget about me! I'm here for Frisk too!" I shouted readying my spear and stood beside Sans in front of Frisk "oh, so the big bad knight of the King's royal guard is going to stop me, don't make me laugh, once I'm through with the three of you I'll take the King's power and destroy the barrier!"

Frisk

"I-i won't let that happen!!" I shouted as I jumped out in front of Sans and Undyne "I will not stand behind my friends, I will protect them! You will not beat me here, Gaster!"

Gaster

"So you've grown a little backbone have you? Alright then, enough games, let's see how strong your determination really is!"

Third Person

Gaster raised both of his hands, the palms glowed red and green, a firestorm and earth fused into one, a skull seething with fire but made of earth was formed, Gaster moved his hand and the skull blasted a fireball twice it's size at Frisk, Frisk created a barrier but changed it's shape, she created a ring that looped all the way back to Gaster who had been watching her very closely, the fireball slammed against the barrier and was directed straight towards Gaster, who disappeared for a moment, and then appeared a few steps away from where the fireball struck, he'd used Blook's power, but Frisk noticed something, when Gaster disappeared the skull would not move, and actually seemed like it had weakened, she was thinking of a plan when Gaster raised his hands again purple and blue, the water formed but no purple was added which meant that the cloud was.. Above! Frisk rolled out of the way as the acid poured down from the cloud, the skulls didn't move, but the cloud did, it seemed to be following the movements of Gaster's hands, he was manipulating her into a position where she would be unable to protect herself, but Frisk wasn't going to let that happen. "Undyne! Throw me your spear!" Undyne who'd been watching the battle intensely snapped out of her trance and threw the spear to Frisk just after yelling "it won't work for you! It'll burn your skin if you touch it! But here you go!" Frisk knew she wouldn't be able to touch the spear directly, she formed a small barrier wrap around her hand and arm and held the spear evenly, she created barriers like steps and jumped toward the cloud and cut it in half with the spear, it dissipated and the glow from the palm ceased, Gaster's smile had faded "kid look out!" Frisk was sent flying from the impact of the earth coated skull hitting her directly, she landed on the ground "done already? That was almost too easy." Gaster looked at Frisk who was still lying on the ground but noticed she didn't have the spear in her possession anymore, instead he felt weaker for some reason, he looked behind him in shock, the purple palm had been impaled with the spear, it turned to dust and Gaster seemed to seethe with anger. "I'm going to enjoy killing you now, you brat!" Gaster shouted as he raised his hands again, his palms glowing white and red, a glowing red skull was summoned and just as Frisk had assumed the other skulls didn't attack while his two palms were specific colors, Gaster had limitations. The skull let out a large blast of flame, Frisk put up a huge barrier around Gaster and the skull, the blast struck the barrier and circled around it inside, Gaster tore through dimensions again but not before getting singed by his own attack, he appeared beside Frisk and grabbed her by the collar and lifted her up, his eyes were glowing, "so you think I'm limited to only two elements at a time do you... Oh no.. I can use all four at the same time!" As he shouted this his left eye glowed blue, his left red, and his palms were left white, right red. Frisk struggled to get loose from Gaster's grip but to success, he had a tight hold on her and wasn't letting up, she thought for a moment, not liking her own idea, but poked Gaster in both of his sockets, his grip loosened as he scowled covering his eyes with both palms, the glow from each was gone and the skulls seemed lifeless, Frisk jumped up and quickly grabbed the spear that had fallen from the purple palm and cut the white palm in half, it turned to dust and Frisk retreated back quickly, Gaster had recovered and the glows were back, though the glow from the red skull was now gone, a pulsing anger could be felt coming from Gaster, "I'll kill you.. Then the humans.. I'll make all the monsters never have to deal with enslavement.. Ever again!" Gaster shouted, he moved his hands and one eye, the skulls moved in unison surrounding Frisk a jet of water shot out from the blue skull, Frisk directed it back with a barrier towards the red one, it fired a blast of flames at her which she deflected back at the earth skull, both skulls were destroyed, Gaster grew annoyed and focused, the water skull dissipated and a rumble from the earth caught everyone's attention, a golem, with three skulls imprinted on it's shoulders and head appeared, green, red, blue, the golem stomped the ground shook and Frisk was forced to roll out of the way, a blast of water shot from the golem's shoulder and Frisk was caught off guard, she blasted into a wall by the water and slid down gripping her arm, it hurt but she was determined to continue, she knew she could win against Gaster, she had to. Frisk stood up, she brushed herself off and raised her barrier up like a shield and charged at the golem, it swung down at the barrier but it's arms were shattered on impact, as was it's body as Frisk crashed into it, the golem crumbled and Frisk saw her chance to charge at Gaster, who disappeared but not before losing the red palm, all that was left was green and blue now.
