As the battle began, Gojo and ERROR404 Sans(5%) stood in the middle of the anti-void, a space in between dimensions where anything goes. The tension was palpable as the two tough guys eyed each other up and down, ready to fight with everything they had. Gojo, usually a laid back guy, knew he had to take this fight seriously if he wanted to win. "Alright, ERROR404 Sans," he said, cracking his knuckles, "let's see what you got." ERROR404 Sans smirked. "Oh, I've got plenty, partner," he said, his voice dripping with confidence. "But are you sure you want to do this? I'm not called ERROR404 for nothing, you know." But Gojo wasn't fazed. He charged towards ERROR404 Sans, looking to land a quick hit. But as he got closer, ERROR404 Sans disappeared into thin air with a teleportation spell. "Heh, you'll have to do better than that, buddy," ERROR404 Sans taunted from behind Gojo. But Gojo was unfazed. He focused his energy and summoned a massive red energy ball, aimed directly at ERROR404 Sans. ERROR404 Sans tried to dodge, but the ball was too fast, hitting him square in the chest. But to Gojo's surprise, ERROR404 Sans didn't seem to be affected by the hit. "What the hell?" Gojo exclaimed. ERROR404 Sans chuckled. "Didn't I tell you? I'm invincible, partner. Nothing can hurt me." Gojo was caught off guard, but he knew he wasn't out of the fight yet. He summoned a blue energy ball, which seemed to have a weaker impact, but it sucked ERROR404 Sans towards him. "Nice try, but you're still not gonna beat me," ERROR404 Sans said, as he unleashed a barrage of 404 blasters towards Gojo. But Gojo was ready, using his infinite void power to become incorporeal and dodge the blasts. The two tough guys continued to exchange blows and spells, with neither gaining a clear advantage. ERROR404 Sans seemed to have the upper hand with his powerful magic and telekinesis, but Gojo's toughness and resilience kept him in the game. Finally, after a long and grueling fight, both tough guys were exhausted, battered and bruised. "I think we both know what's gonna happen now," ERROR404 Sans said, with a hint of respect in his tone. Gojo nodded, summoning his giant purple energy ball, mixing his blue and red energy balls to create a massive explosion. It hit ERROR404 Sans head on, obliterating him completely. As ERROR404 Sans faded away, Gojo breathed a sigh of relief. "Phew, that was wild," he said to himself. But deep down, he knew that this wouldn't be the end of his battles in the anti-void. He'd have to keep getting tougher if he wanted to survive in this crazy space between dimensions.
