The dimly lit underground arena was set for the ultimate showdown between Sans The Skeleton and LV 20 Frisk. The tension in the air was palpable as both the combatants strutted their stuff to impress their fans. And thus, the bell rang to signal the beginning of the ultimate heavyweight battle. Sans The Skeleton was the easiest enemy in his world, but his powers were not to be underestimated. His blue flame eyes, which could give Frisk's soul gravity, were enough to knock back the toughest of opponents. On top of that, his Karma Retribution attack inflicted poison on his enemies, leaving Frisk with a difficult path to victory. On the other hand, LV 20 Frisk had a real knife as their weapon, and their armor came in the form of the Locket, making them a force to be reckoned with. The Erase ability that Frisk carried made them a dangerous combatant, and their skillset was nothing short of impressive. Both beings sized each other up, and a brief moment of silence passed before Sans made the first move. With his slight frame, Sans lunged towards Frisk and got his Gaster Blaster power ready. The Skeletal-like faces shot out beams of light, leaving Frisk no option but to dodge or suffer countless damage. Frisk had no difficulty in dodging the first few attacks from Sans, and they retaliated quickly with their Inhumane Rush. Frisk landed five quick slashes, followed by a powerful knockback that left Sans struggling to get his footing. But Sans immediately recovered and countered with his Bone Manip, throwing out random bones in Frisk's direction. Frisk dodged each bone easily while retaliating with their Inhumane Dash. The teleportation allowed them to move behind Sans, and Frisk quickly launched an array of slashes at Sans's back. But Sans was resilient, and he used his teleportation powers and dodged the attacks quite impressively. To gain an advantage, Frisk decided to use their Haemorrhage attack and dashed back. Frisk shot out three slashes at varying angles towards Sans' front, hoping to catch him off guard. The attack hit perfectly and caught Sans in a vulnerable spot. Sans was now starting to feel the pain, and he decided to activate his Badtime Mode. In this mode, Sans' magic and speed increased by 10 times, making him a powerful force to be reckoned with. Frisk was visibly nervous, but they had to continue with the fight. Sans lunged towards Frisk like a missile, and Frisk barely managed to dodge. But once Sans had activated his Badtime mode, there was no stopping him. He countered with his Gaster Blaster power, this time using the Giant Blaster variant. The blast was too powerful for Frisk and hit them squarely, knocking them down. The pace of the fight had increased drastically, and both combatants were severely injured. Each one of them knew that one wrong move could end the fight. They continued the fight with all their might, each one of them trying to land a decisive blow. It was Frisk's turn, and they decided to use their Thantophobia move. Frisk teleported around Sans, saving and loading their positions, and launched an array of slashes. Sans could barely keep up with Frisk, and he knew that this might be his last stand. Sans decided to launch one last attack, using his Side Blaster variant of the Gaster Blaster. The blast shot out multiple beams of light in varying directions, hoping to catch Frisk off-guard. But to Sans's surprise, Frisk had already seen it coming and used their Erase ability at the perfect moment, making the attack null and void. Frisk seized this opportunity and launched an Inhumane Dash, followed by a powerful set of slashes. The slash cut deep into Sans, and Frisk knew that they had won the fight. They took a deep breath, and the bell rang, signaling the end of the battle. In conclusion, the winner of this ultimate heavyweight battle was LV 20 Frisk. The reason behind this lies in the fact that they had multiple skills at their disposal, and they could adapt to situations easily. The Erase ability allowed Frisk to nullify Sans's attacks and the powerful Inhumane Rush made sure that Sans could not get close to Frisk. It was a close call, but Frisk came out on top, victorious.
