Mimi never trained with her power, always just being big believing it was enough. Against Harmony, who with learning the fruit's name was able to use its power, being as big as her with actual combat experience from childhood, this got very one sided. Mimi did her best but Harmony was in her head as she faked-out and just wholloped her in the side of head, knocking her down. Harmony then jumped up, growing to the max size the fruit allowed of 50 feet, and landed on Mimi's back, causing her to pass out and return to normal size. Harmony shrunk as well, panting rather heavily as holding the increased size took genuine effort. After catching her breath, she ran up the hill quickly, but was carefully not stepping on any flowers.
Harmony's impact shook the entire island, throwing everyone off balance at the battle sight. Ballgoon bounced after falling, doing a flip and landing on his feet. "Mercury! Hurry up with those two and stop that creature! Don't say your fruits name to her!" Kasai rushed ahead, giving Julio a window to dive for Victoria and roll forward, shooting right at Ballgoon, but the coin just dug into him before bouncing back at Julio, who just ducked in time. "My fruit turns me into an invincible force of destruction!" Ballgoon bragged, as he had the Pump Pump Fruit, which while not turning him into rubber, does make his body stretchy and completely hollow. He can pump air into any part of his body, and can even choose if the air can escape through his skin.
He started pumping his arm with air with the fruit, his arm inflating to a huge size before he tried slamming Julio, who rolled out of the way. He reeled back shaking his hand before reaching for Julio with the huge arm. "Minx, tag out!" Julio jumped back as Minx leap-frogged over him, spinning his daggers and cutting open his hand, causing all the air to escape which flung him back. Julio ran over and picked Kiwi up. Seeing an opening, he looked back saying, "You guys take this, I'm getting him to safety!" before running back towards the Nakama, avoiding the flowers.
Kasai took a gut punch from Mercury, causing him to cough up blood even with his scales. He thrust his own Ryuo fist into Mercury's gut, causing him to cough blood as well. They both traded a blow to the face, when Kasai shifted fully into a wyvern and spun around, smacking him with his tail coated with Ryuo. Mercury blocked, but it still pushed him back. He grabbed the tail and slammed him into the barn debris, but Kasai flapped his wings just right and instead flipped Mercury and bashed both him and his tail into the ground. Mercury coughed, falling back as he returned to a frail old dude.
Minx dashed towards the balloon man, who pumped air into his fist and went for an uppercut. Minx sidestepped and slashed at his side, but his daggers just snagged on his body, not slicing through. "Can't cut unless I'm tensed up. Pretty useful ain't it?~" He pumped air into his pointer finger and then aimed at the pirate. "Pop~" A blast hit Minx with condensed air that flung him back, the impact knocking the wind out of him. Ballgoon looked towards the coast where Nakama was, seeing Julio with his trillion beli. Angrily he cried out, "Bring me back my money!" as he pumped up his legs, and used a pop to launch himself at them.
Kasai stepped up to pursuit, but then a stretched arm coming from behind them grabbed Ballgoon's face, steering his momentum back at the barn. As her arm snapped back, Harmony walked towards where he had landed. "My turn." Kasai nodded in understanding as he flew off, deciding to collect the fallen so no one escapes. Harmony and Ballgoon glared at each other, and he laughed at the situation. "Look at me, a mere million trying my grit against a ten. I can't wait for the bounty increase I get taking you out!" He pumped up his arm, and tried striking her, but she moved her body and brushed past it. She punched his face, her fist just digging down with no effort before she's flung back. "Even your stolen Mega power can't beat me! I'm unbreakable!" She smirked. "You also have a limit though don't you?~" He chuckled nervously, as an idea brewed in her head. "You don't inflate that much. You can only take so much strain. But I'll bet my stretch can out do yours~" she said confidently, settling on her plan.
