As the battle began, Sans Undertale immediately summoned bones and gaster blasters to attack his opponent. But to his surprise, the last sans was too fast and too powerful for any of his attacks to land. The last sans easily dodged his attacks and countered with a swift punch which sent Sans Undertale flying backward. Realizing that he needed a new approach, Sans Undertale decided to use his Karma ability which allows him to deal extra damage to evil opponents. As he activated his power, the last sans suddenly became engulfed in a beam of light as Sans Undertale dealt critical damage to his opponent. However, the last sans was not one to be taken down so easily. Once again he appeared behind Sans Undertale and took advantage of his opponent's reduced guard to land a powerful punch. Sans Undertale was now heavily injured and it seemed like he had no chance of winning this battle. But then something strange happened. Sans Undertale's body began to glow in a bright blue light and his wounds slowly started to heal. It was as if his body had activated some kind of hidden power. Feeling a renewed sense of confidence, Sans Undertale decided to use this newfound power to turn the tables on his opponent. With a swift movement, he summoned a wall of bones which served as a barrier between him and the last sans. The last sans tried to break through the barrier, but Sans Undertale had enchanted it with a powerful spell that made it nearly unbreakable. Seeing that his attacks were getting him nowhere, the last sans decided to use his ultimate move - the omniverse trap. The entire battlefield began to shake as an enormous cage made out of pure energy enveloped Sans Undertale. It seemed as though there was no way out for Sans Undertale as the cage seemed to be tightening around him. But once again, Sans Undertale surprised everyone by using his reality-bending powers to teleport outside of the cage. The last sans was stunned by this move and it gave Sans Undertale the opportunity he needed to launch a powerful counterattack. With a shout, he summoned an army of bones and gaster blasters which engulfed the last sans in a barrage of attacks. The last sans tried to dodge and weave his way out of the attack, but there were simply too many bones and gaster blasters to avoid. Finally, the last sans collapsed to the ground defeated. Sans Undertale stood over him breathing heavily, but feeling exhilarated by the victory. He had proven that even though he may seem lazy and relaxed, he was a force to be reckoned with when it mattered. As tuki looked on, he couldn't help but feel impressed by Sans Undertale's victory. It was clear that his power and abilities were not to be underestimated, and he had proven that when push comes to shove, he could hold his own against even the most powerful opponents.
