"PLEASE, I WOULD APPRECIATE IT IF YOU GOT OFF OF MY LEG!"

Papyrus just kept on stomping him. Gaster held on tightly to the skeleton's femur, draining the SOUL-powered energy inside him, but he was having trouble as Papyrus kept on doing damage. Suddenly, Pap's foot fell one more time, but it hit nothing but a goopy mess. Gaster had once again lost all material substance and sank into the ground. Papyrus fell to his knees and began breathing heavily. Sans instantly teleported over to him.

"you ok, bro?"

"YES, SANS, I'M FINE, YOU DON'T HAVE TO WORRY ABOUT ME! I JUST NEED A SECOND TO CATCH MY BREATH…"

"are you sure, pap?"

"YES, SANS. SAVE FRISK, DON'T WORRY ABOUT ME. I'LL BE FINE. YOU SAW WHAT JUST HAPPENED TO GASTER WHEN HE TRIED TO STEAL MY POWERS."

Sans smiled lovingly.

"yup. he sure had a bad time."

Papyrus beamed at the praise. Suddenly, the ground rocked with what felt like a massive earthquake.

The skelebros turned to look behind them and saw that Gaster had engaged in combat with Asgore. The massive goat king was shaking the ground with every strike, every stomp, every step, every movement. Gaster was dodging each blow, but it was obvious that if any of them landed, he would be in for a beating.

Asgore stomped the ground, hard, causing cracks to snake out across the earth. At first, Gaster was unimpressed, thinking that it was a kind of boast, a showing of the king's power. Ol' W. D. had seen much better. Suddenly, however, lava and flames burst out of the cracks, forcing Gaster to take a few scorching hits in order to escape. As soon as he exited the trap, he was met with Asgore's titanic fist to his face, sending him flying hundreds of yards before he landed on his feet and fired an invisible pulse of energy at the king, striking and stunning him.

Suddenly, Gaster was struck from behind by another massive punch, the strength of which rivaled that of Asgore himself. Turning, he realized that he had been hit by Alphys' newly built war machine, and that Undyne was standing atop it's chassis, spear in hand.

Gaster thrust out his palm and blasted the duo with a pulse of energy, before following it up with an unstoppable wave of scorching fire magic developed from studying Toriel and Asgore.

The smoke cleared, and Alphys was smiling.

"If you want to beat us-"

Suddenly, from behind the mech-suit, Undyne leapt high into the air, firing spears of light from the magic weapon she held and pinning Gaster to the ground. At the same time, she finished Alphys' phrase.

"You'll have to do better than that!"

Gaster realized suddenly that he was open to a follow-up attack from either of the two, not to mention from anyone else in the area. Melting into goo, he sank into the ground, avoiding any possible damage.

Gaster rose from the ground a few hundred yards from the battlefield and tried to catch his breath. He was superior to any one of them, but all of them together could give him a lot of trouble. He could feel Frisk's SOUL inside them, beating furiously, fighting against him. He knew that if he RESET, the SOUL would simply go back to before Gaster showed up, and Sans, Frisk, and possibly even Asgore would remember the day's events, and be prepared. He had to wait until the SOUL was assimilated before he could RESET and take total control of the timeline.

Gaster's thoughts were interrupted by a serene and yet furious voice from behind him.

"W. D. Gaster. You seem to have forgotten why you came here. Were you not trying to kill us seconds before now?"

Gaster spun around and shot a massive wave of fire magic at Toriel, who stood behind him. The goat woman, however, easily countered with her own burst. Gaster lifted one of his hands into the air and collected all of the darkness in the area into his palm, creating a massively powerful blast which he then hurled at Toriel.

The woman barely had time to prepare herself before the attack hit, and all she could do was cushion her impact by putting her hands out before her, catching the ball. She struggled against the attack, before she suddenly noticed a blue glow emanating from it.

The ball began to lose momentum, before being hurled entirely in the wrong direction, back at Gaster. The enigma put out his palm and sucked the energy back into it, before glaring at Sans, who simply shrugged.

"Where were we?"

"I was preparing to kill you."

"Ah, that's right, thank you. I was preparing to kill you."

"Very funny. But I think that you should expect more from me than an easy death."

"You used to work for my husband, correct?"

"Yes, I was once the royal scientist for King Asgore."

"Then you should be used to getting served by me."

"Ooh, savage. Yes, I recall the pies you always brought to the royal company picnics."

Toriel didn't reply. Gaster had kind of ruined her joke. Instead she summoned dozens of fireballs which all rotated around her in a deadly fiery ring. Gaster raised his hands and did the exact same thing. They each shot the blasts at each other skillfully, each attempting to order their fireballs to evade those of their opponent and hit their mark, but in the end all were destroyed in collisions but two, and this time, Toriel succeeded in hitting Gaster. While her ex-employee was stunned she prepared and fired a massive ball of fire. Gaster was about to dodge when he felt the SOUL inside him increase exponentially in weight… and turn blue.

Damn that Sans. Damn him straight to hell.

The massive blast of fire singed Gaster badly, but he'd been through worse. He turned and looked at Sans.

"I originally planned to save you for last, but you've proven so annoying that I don't feel that I can afford to do so."

Gaster raised his hand, and a field of pure darkness suddenly surrounded Sans.

"Tell me, Sans, have you ever tried to dodge a room shrinking and crushing you from inside?"

Sans' smile became a bit less genuine.

Gaster closed his fist, and the field of darkness surrounding the big-boned skeleton began to solidify and harden. An instant before it had a chance to do so, one of Sans' Gasterblasters flew at far faster than the speed of light to close it's titanic jaws around it's master to protect him.

The Darkness closed in, and a sickening crunch could be heard. Papyrus went into shock instantly, staring blankly forward, and fell to his knees. He had been just about to rejoin the fight.

A shocked Toriel rushed toward the large chunk of solid darkness that now lay on the ground and fell to her knees next to it, beating it with her fists.

"Sans! Sans, no!"

For the second time that day, although this time unbeknownst to Toriel, a blue light began shining out of the darkness, lighting up the area.
