"Your brave kid, for hurting my son," Big Mom who suddenly appeared benign Xin gloomy said while looking at him.
Xin turns around and sees Big Mom big change, the happy go lucky Yonko suddenly changes into a demon.
Behind Big Mom is a blazing ball of fire and a black thunder cloud with sinister-looking faces, these two animated creatures are made from Big Mom's ability.
Prometheus the Sun is a sun homie that Big Mom summons from her right hand.
Prometheus is a mass of compressed flames with several sunrays surrounding it, giving it the appearance of a miniaturized sun. Its eyes and nose are very close together and are small compared to its largemouth. It has blushy, rosy cheeks and is usually seen with a toothy smile.
When it uses its power, its appearance changes, and it resembles a fireball while its facial features remain, though it can take on a more sinister appearance. While sleeping, Prometheus does not exude any sun rays nor light, instead of appearing a mere orb with a face floating in midair.
Zeus the Thundercloud is a thundercloud homie created and formerly owned by Big Mom, that she summoned from her left hand.
Zeus is a cloud that normally appears large and light-colored. When he causes a storm, he turns dark. He also wears a striped red and white baseball cap with a yellow brim on his head. He usually has a carefree, sleepy expression, but can take on a more sinister appearance.
And lastly is the sword that Bih Mom holds, Napoleon.
Napoleon is a homie taking the form of a bicorne hat that is worn by Big Mom. It can also become a sword that Big Mom uses in combat.
"Kid, you are really brave to destroy my Tea Party and hurt my son," Big Mom sinister said.
"Well, I'm not really coming for your Tea Party, I came here to test my strength on you," Xin grinning said.
"Want to test your strength using me? Then die, Napoleon Hahaba!" Big Mom said.
"Yes Mama!," Napoleon said.
Napoleon change into a gigantic Cognac and turn to a sinister weapon in front of Xin,
All of the people around the room suddenly become pale, they feel that Big Mom is going to do something stupid this time that will endanger all of them.
"Be slice kid, "Blade of Destruction"." Big Mom then swings horizontally to where Xim is. Xin calmly twirls his Stone staff and stabs it in the ground.
All the people in the room become pale in fright seeing the sword coming to them too, because of Napoleon forme the slicing power is longer and powerful
Even Stussy who is close to Xin, her legs become weak and fall to the ground, she helplessly looks at the incoming slice attack of Big Mom.
'I'm going to die here? I still want to find my other half,' Stussy helplessly closes her eyes and waits for her time.
Meanwhile, the other people around scare shit less, while others are frantically running to escape.
"Hardening!"
Xin's arm turns into gold color then holds his stone staff tightly, the Cognac and Stone Staff hit each other creating a wave of haki around.
Even though Xin is already holding his stone staff tightly, he is still being pushed by Big Mom's tremendous strength.
Xin then stamps his right foot on the other end of the staff and uses hardening to stop the pushing power.
Big Mom suddenly felt that the swing power started to stop by Xin's strength until it finally stopped beside Stussy and the other Underworld Kings.
The Underground Bosses felt relief looking at Napoleon that inch away from them, they thought that they were dead this time but thank goodness Xin stopped the attack.
"What!!" Big Mom and Napoleon were surprised how this kid easily stopped the swing, they both know that only Kido can stop that attack but who thought that there's another one who contends to Big Mom's raw strength.
"Too strong but I can still stop it," Xin said.
Even Xin did not expect that Big Mom could drag him 2 meters away from his original position.
"That's only luck, take this kid," Zeus angry said.
"That's right, you will pay for it," Prometheus nodded.
"Prometheus, Zeus, come," Big Mom shouted.
"Yes, Mama," Prometheus, Zeus come to the left and right hand of Big Mom.
"Then escape from this Kid,"
"Thunderbolt"
Big Mom summons Zeus around her left hand and then slams them down on Xin, striking them with a massive bolt of lightning.
Seeing the incoming thunderbolt up in the air, Xin uses his armament in both hands then raises it as if trying to catch it.
"Hehe idiot kid, no one can escape from the power of nature!," Big Mom said.
Xin only grins at her and catches the gigantic thunderbolt with a b.a.r.e hand, Xin's feet sink to the floor while carrying the tremendous weight coming above.
Big Mom, Prometheus, and Zeus lunch when they see Xin grabbing them, the thunder that they release is strong enough to roast anyone but this kid actually grabbing them.
Big Mom suddenly raises her feet and delivers a haki coated kick to Xin, but Sin is always prepared for a sneak attack.
He also coated his feet with Haki and intercepted Big Mom's kick., after intercepting, Xin bow down slightly and push Big Mom's hand up in the air.
After creating an opening Xin grab his stone staff that stab on the floor and smack Big Mom's like a fly
This time Xin did not hold back, he used all his strength, cousin Big Mom, causing a large part of the castle to be destroyed.
All of them were shocked to see Big Mom's body fly to the wall and fall outside, creating a long stretch line in the ground.
Xin looked beside him and tapped Stussy's shaking shoulder, and whispered," Hey Miss, you need to escape from ehre, the next fight will be more dangerous."
Stussy's eyes slowly one, she sees a white figure in front of her saying that she needs to escape, but she doesn't know why she seems attracted to the white figure in front of her.
"Are you fine?" Xin's voice bring Stussy back to reality, she hurry stand and run, but before he even takes 3 steps she looks back and said," Be careful,"
Xin gently smile and reply," I will,"
Stussy then escapes reactant looking back at Xin, while Xin looking at Big Mom whos anger already reaches to the max.
Xin grin and sprint straight to Big Mom to start the second round
