Sans and Luffy stare at each other across the battlefield, both sizing up their opponent. Sans: "Well, well, well. Looks like we got ourselves a rubber man, huh?" Luffy: "That's right. And it looks like you can control bones. Interesting." Sans smirks and creates a wall of bones behind Luffy. He quickly turns around as the bones come hurtling towards him. Luffy: "Gum Gum Balloon!" Luffy inflates his body and the bones bounce harmlessly off of him. Sans: "Impressive. But let's see you dodge this!" Sans starts launching bone projectiles at Luffy, who dodges them easily using his Observation Haki. Luffy: "Your aim needs work, Sans." Sans: "Maybe so. How about this then?" Sans charges at Luffy, but the rubber man quickly grabs him and slams him into the ground. Luffy: "Gum Gum Pistol!" Luffy hits Sans with a powerful punch that sends him flying. But he quickly gets back up, fully healed thanks to his Crossing Times ability. Sans: "You're a tough one, I'll give you that. But can you stand up to this?" Sans enters his second life phase and creates a massive bone army to attack Luffy. Luffy tries to fight them off, but they just keep coming. Luffy: "I need to end this now!" Luffy powers up and prepares to use his Gum Gum Bazooka. But Sans is ready for him. Sans: "Not so fast, rubber man. Bone Wall!" Sans creates a massive wall of bones to block Luffy's attack. Sans: "And now, it's time to finish this. Dying is Gay..!" Sans enters his third life phase and charges at Luffy with incredible speed. Luffy: "I won't let you win!" Luffy uses his Gum Gum Bell attack, but it misses and Sans lands a devastating blow. Sans: "It's over. Remember son, dying is gay." Winner: Sans Sans was able to outlast Luffy with his abilities and strategic use of his phases. Luffy was a tough opponent, but he couldn't stand up to Sans' final attack in his third life phase.
