Size vs weight

Chaos and death filled the surroundings of Bege's old mansion

From the ground, hundreds of supernatural wolves destroyed, tore and devoured filler gangsters. And at the same time, from the falcon that had the same abilities as Capone Bege, cannon shots and ghosts rained down from the sky, causing incessant explosions over the people.

They had practically massacred all their rank and file gangsters.

In a few seconds, godfather Columbo Andrew would be left without a single subordinate and he had seen how his partners had been kidnapped, but now that was no longer a priority problem.

Daz Bones and Laffitte had already chosen their adversaries and it was only a matter of seconds before their battle began. He really wanted to join Laffitte to kill his most hated enemy, but first he had to take care of an annoying obstacle that was preventing him from moving forward.

"Let's fight!

You cannot face the FINAL boss without first defeating the MINI boss

HIAHIAHIAHAAAAAHAHA!" David laughed at the top of his lungs at his own joke... but he stopped after a few seconds, somewhat sad to see that he was the only one laughing. "Fred-sensei found this joke funny…"

"GET OUT OF MY WAY!" Shouted Andrew while leaving David behind "I don't have time to waste on an idiot like you…"

Andrew was fast, incredibly fast even among super humans, so he left David behind in a flash.

He wasn't against breaking every bone in David's body for bothering him, especially now that he was extremely angry. He didn't want to waste his energy fighting this buffoon who meant nothing to him, his true goal was to kill Fred, the true source of his anger.

However, Andrew couldn't get David off of him, at least not for a long time.

"Come on!" David said, almost face to face with his possible playmate. "I need someone to test my new ninja weapons on!"

Andrew didn't know how David managed to catch up with him every time he left him behind, he didn't seem to be that fast, especially when he was carrying such heavy weapons.

"A shield and a jousting lance!?" Shouted Andrew just before accelerating again, angrier than before after that nonsense "SINCE WHEN ARE THESE NINJA WEAPONS?"

Andrew was right, David wasn't especially fast and the Mini Mini hadn't made him faster despite making him smaller. Despite shrinking, David retained his giant's physical abilities, so he was always the same strong despite reducing his size or weight.

Normally that should make him exponentially faster, since he was moving much less mass with the same force, but that doesn't apply with the Mini Mini No Mi. Despite weighing and measuring less, his giant strength, mass and density remained the same for many things, including calculating his speed 

"They're giant ninja weapons!" David shouted after catching up with him again. He was like a little child showing his Christmas gifts to his friends. "And Stephen they also made me a short sword.

Cool right?"

The mechanism behind David's incredible acceleration was simple. David simply leaned towards his enemy and returned his legs to their original size. The simple increase in size was already enough to lengthen distances, but doing so at a speed comparable to that of a cannon shot catapulted him at great speed.

David not only learned to use size recovery speed offensively, this ability had many applications if is used well.

'Damit…'

Andrew took the hint, he wouldn't be able to get rid of him and David wasn't a weakling. Maybe he wasn't even stupid or at least childish. It was very likely that this annoying act was deliberately planned to get on his nerves and thus force him to fight him (no, it's not...)

"Okay..." Andrew said resignedly, Fred would have to wait his turn. "If you insist so much I'll kill you first…"

Unlike the other three mob bosses who had inherited his parents' family, Colombo Andrew and like Capone Bege, earned his place at the top of West Blue organized crime with his own power.

Andrew was born with an extremely strong body, a good talent for hand-to-hand combat, an aggressive personality and also the luck of eating an Akuma No Mi that complemented him very well, the Kiro Kiro no Mi.

The Paramecia-type Devil Fruit that allows the user to change their weight from 1 to 10.000 kilograms without, in any way, affecting the overall size of their body.

A simple power, at least in theory, but Colombo learned to use it masterfully after so many years.

FIU!

Andrew reduced his weight, including his clothing and equipment, to just one kilogram. But he did it without affecting his physical strength in the slightest, lightening the load his muscles had to move and therefore increasing his speed drastically.

'The fuck!?'

Andrew had been fast before, but not that fast; he had been holding back to take Fred by surprise and now he had succeeded with David. 

David wasn't expecting that sudden increase in speed. Before he could realize Andrew was behind him to hit him with the full force of his gauntlet-fortified fist, his most powerful weapon and attack.

10 Ton Punch!

Instead of increasing his entire body weight to reach 10 tons, Andrew concentrated all that increase solely on the fist with which he was going to attack. A powerful right hook that didn't lose speed or precision in the slightest.

A peculiarity of the Kiro Kiro no Mi's and its increased weight ability is that it doesn't affect the movement capacity of the user's body, no matter how much weight he was able to carry. 

The user always feels that he or she's moving with his or her original weight when it has increased.

However, the Kiro Kiro no Mi translated that increase weight gain into destructive power for the rest of the world!

David knew that, that's why he instinctively felt so afraid after sensing that he could be hit squarely in the head.

Do you think a punch from Garp is destructive? Imagine if that fist weighed ten tons instead of one or three kilos at most!

Andrew is no Garp, but still being hit by such a small 10 ton object accelerating at that speed was dangerous even for a giant.

David didn't have time to turn his shield or dodge that attack for which he wasn't prepared and although he was confident that this impact wouldn't knock him down, he didn't want to risk suffering that amount of damage.

Fortunately, David had an emergency escape technique that didn't require the use of any muscles

Shrink!

Tenths of a second before the 10-ton iron fist hit his head, David shrank and successfully avoided that attack. But that evasive maneuver wasn't a stroke of luck resulting from improvisation.

One of the many trainings David practiced since obtaining the Mini Mini No Mi was to instinctively shrink parts of his body before being hit. To this day he could remember how Fred trained him, as if he had flashes of Vietnam.

'If you can dodge my bullets you'll be able to dodge... the shurikens!'

BANG! BANG! BANG!

'AU! AHHHH!!!

Is this really necessary?

Aishhhh...!

Can't we practice with something less dangerous, like balls?'

'No! And later you'll have to dodge my sword blows, so you'll be able to dodge... the punches and kicks.'

David was still convinced that this training was unnecessarily dangerous and had one or a couple of things that didn't make sense, but he couldn't deny that the results were outstanding. He wouldn't have been able to dodge that blow if it hadn't been for the fact that he had reached a point where he could shrink by reflex like a successful Logia user.

'Thank you Fred-sensei!' David thought, moved like Daniel-san after discovering that he learned karate and cleaning the house at the same time. 'I should never have doubted your teachings'

While...

"What the fuck!?" Shouted Andrew, almost with his eyes popping out of his sockets "Has he gotten smaller?"

Without further ado the tiny David pointed his tiny jousting lance called Gugnir towards his enemy. A jousting lance whose shape greatly fascinated Colombo Andrew with every detail.

Aside from the hilt, which was artistically difficult to describe, the rocket in front of him wasn't made of a single cylindrical piece of steel, but of four long, wide, solid, sharp blades joined together as if they were the tip of a star turntable. (the design is similar to the one that can be seen in the manwua [The Knight King Who Returned with a God], chapters 14 and 34)

'It's beautiful... I would love to have one like this one adorning the fireplace of my house...'

A sleek and cool design but extremely heavy and difficult to handle for a person without enough strength in one arm. However, if someone could dominate her she could do wonders, or at least that's what Andrew understood in such a short time.

This jousting spear couldn't only be used as a spear to pierce enemies. Being made up of four blades, it could be used as if it were a four-edged sword and, being so heavy, it could also work as a cutting club 

A deadly work of art that even Andrew now wanted to wield even if he didn't use weapons.

'One moment...

Because I'm wasting my time thinking about this and how the hell am I having time to think about all this?'

Colombo Andrew watched as little David was still suspended in the air, still pointing his wonderful jousting lance at him. He was still in that position even though Andrew may have had dozens of thoughts until now.

It was almost as if time had slowed down.

'OH SHIT!'

Something very similar to what happens moments before death.

SPLASHHHHHH!!!!

Time returned to normal and David's jousting spear grew dozens of meters in an instant, destroying absolutely everything in its path. The grass, the asphalt, the fountain, the plants, the trees and even the garden wall of the mansion that communicated with the outside.

The only reason Andrew wasn't included in that list of defects is because he was able to react thanks to that paranormal situation from which he was able to escape in time. In an instant Andrew was able to reduce his weight and thus avoid that deadly attack by a hair, receiving only a cut on his face, losing part of his ear and also a few years of his life.

Andrew had just narrowly escaped death and his heart was racing, his body was drenched in cold sweat and he might have wet himself if he hadn't emptied his entire tank before the fight. Andrew hadn't recovered from this experience, but he knew that he couldn't afford to back down.

Andrew understood that David is not a clown, he's extremely dangerous and he had to attack him relentlessly and risk his life in each attack if he wanted to win.

FIU!

Just after dodging death Andrew tried to land with his most powerful punch, praying that he could catch David more off guard than he had been a few moments ago and thus end this combat.

GOONGG!!!

But it wasn't possible!

The circular shield that seemed to be far from the reach of his fist suddenly grew and blocked Andrew's ten-ton punch, thus frustrating his incredible counterattack.

That was incredibly frustrating and also mind-blowin

Andrew couldn't understand how after delivering his most powerful blow, that shield was still intact and David didn't retreat a single millimeter. 

The change size ability of his opponent' was very annoying, versatile and powerful despite looking so simple. Not only does he have a brutally offensive ability with his spear, he could also easily evade and raise defenses in a second.

His opponent had better reflexes than he thought. Otherwise, he wouldn't have been able to stop a counterattack like this.

But above all...

Andrew couldn't understand how after hitting it with his most powerful punch, that shield was still intact and David didn't retreat a single millimeter.

'Is this guy... even human?'

Usually everyone who received his fist was smashed into a wall, even if they blocked it with a shield!

Andrew was completely dismayed by just imagining the physical strength of his adversary and that small, insignificant loss of time once again made the difference between his life and death.

FLAAAAAAAAAAAAAHHHHHHHHHHHH!!!!

Andrew had no Observation Haky, even so his fighting and survival instincts, which had been sharpened after his near-death experience, warned him that something extremely dangerous was approaching from his left and that he wouldn't have time to avoid it this time.

David had swung his extremely gigantic jousting spear sideways with all his might to slash and shatter him at the same time with one of his swords, a blow that would be fatal even if he blocked it.

If it weren't for one of the Kiro Kiro no Mi applications!

The user of the Kiro Kiro no Mi doesn't suffer from the mobility problems and danger of death expected in a normal-sized human being with an overwhelming weight of 10 tons.

On the other hand, the Akuma No Mi didn't increase the density of his body to make him extremely resistant to physical attacks. However, an experienced user could break this rule to increase body density in exchange for remaining completely still.

Just like Andrew and even Mikita, that was able to emerged unharmed from meteoric falls thanks this ability!

To survive Andrew protected his body with his gauntlets to block the blades, he dug himself into the ground as hard as he could, tensed all the muscles in his body, clenched his teeth, increased his weight to 10 tons thus increasing the density of his body accordingly and...

PLOOOOMMMMMMMMMMMMMMMMMMM!!!!!

CRASHHHHH!!!! CRASHHHHH!!!! CRASHHHHH!!!! CRASHHHHH!!!! CRASHHHHH!!!! CRASHHHHH!!!! CRASHHHHH!!!! CRASHHHHH!!!! CRASHHHHH!!!! CRASHHHHH!!!!

Andrew flew out and passed through the far wall of the garden, dozens of trees in the forest surrounding the mansion, and even a few small mountains and large stones in his path.

Despite having blocked with his best defense, Andrew was completely defeated with a single attack.

His gauntlets had broken down and his arms were completely purple. It was more than evident that they had been broken and not in an easy way to heal.

The ribs that cushioned part of the blow had also been shattered and his internal organs had taken quite a beating as well.

Andrew was on the floor vomiting blood, struggling to stay conscious...again. He already lost consciousness within moments of receiving the first blow and woke up again when the stone mountain he was trapped against stopped his aerial journey out of the island.

'What kind of monster have I been facing?

I have never had a single scratch done using that technique...

It can't be... not even Fred has such strength...'

Since then Andrew had fainted several times, but the reputed mobster fought again and again to stay awake. The battle wasn't over and it was more than evident that his enemy would look for him to finish the job. He couldn't afford to give up, even if it might minimally alleviate the humiliating pain he was feeling.

"Ugh... thank goodness, I almost killed him.

Fred would have been angry with me…"

David followed the path of destruction that he had created and finally came across Andrew, who was completely motionless and embedded in a stone wall near the emblematic Ballywood sign.

With some care David pulled Andrew out of the stone and carried him on his back. He wanted to take him back to the mansion instead of giving him the finishing blow.

'Thank you,' Andrew thought, deeply relieved. 'Thank you very much...

THANKS FOR GIVING ME THIS OPPORTUNITY!'

If David had hit him one more time with his spear, Andrew wouldn't have a single chance to win, he would have died with just two hits.

However, what David did changed everything.

Andrew barely had the strength to fight against anything, much less a monster with super superhuman strength like David

Even if Andrew now, who was pretending to be asleep, suddenly increased his weight to 10 tons, he had a feeling that his enemy could bear it, but he was confident in his next move.

10 Ton transfer!

After years of training, Andrew discovered that by touching a person or object directly with his hands could also increase or decrease its weight. However, unlike the user of the Kiro Kiro No Mi, the rest of the living and non-living beings did feel the true effects of seeing the weight of their body changed.

Both negative and positive effects.

"UGH?!"

It's extremely simplistic to think that drastically increasing your weight only hinders your ability to move and get off the ground.

Muscles and ligaments would tear more easily and bones could be broken with much less effort. The blood in the body would become heavier, so the heart would have to work harder to circulate it through the body, making breathing very difficult.

Many other things could go wrong with this weight change, which wasn't much different from increasing gravity.

In theory, an increase in G force between four and five times was fatal for a human being, since blood could no longer circulate through the body.

And now Andrew had set David's weight at 10 tons!

The weight of someone with David's physical characteristics was around 100 kg of almost pure muscle. Multiplying that weight by 100 was enough to make irrelevant many of the concerns mentioned above. Death should have been almost instantaneous for hundreds of reasons, even in a fantasy world with superpowered people like this one.

'GOOD! GOOD! 'Andrew thought euphorically as he held the back of David's head with his broken left arm. 'I WON'T BE ABLE TO KILL FRED! BUT AT LEAST I'LL FINISH ONE OF HIS FRIENDS!'

The other people who had experienced this ability died instantly, but Andrewn didn't want to risk it. He also had to kill him the old fashioned way just in case.

Andrew didn't have the strength to kill his rival with his fists, but he always carried a knife with him. His arms were completely destroyed but despite that he used all of his will to wield the knife despite the searing pain he felt to slit the throat of his enemy, but...

"Wow" David shouted, deeply surprised by his sudden increase in speed. "I feel very light"

David momentarily lost control of his body and accidentally dropped some of his luggage.

"UGH?!" Andrew shouted after failing and also falling to the ground "No... way..."

The only problem with Andrew's plan is that his enemy was David, a giant with a 55-meter body that weighed almost 100 tons.

Although he had now reduced his size and weight thanks to the Mini Mini No Mi, his real giant body was fully capable of supporting 10 tons and much more weight. The only thing he had managed to do was increase his speed and not crush him with his own weight.

Because of that imbalance Andrew fell to the ground and didn't have much time to think about why his powers had failed, since a new problem fell upon him. That problem was the circular shield that David previously had on his back, which had now become so large that it practically covered the sky.

'Shit! Shit!' Andrew thought desperately as he saw how that giant shield was approaching him 'I can't move and it's no use increasing the density of my body, I'll die of suffocation anyway!

I can't even use my arms!'

He was in a desperate situation but Andrew still didn't throw in the towel, he could still move his legs and he hadn't run out of resources with which to survive this situation, even if it was risky.

In the same way that Andrew could make anything he directly touched weigh 10 tons, he could also make it only weigh 1 kilogram. That's precisely what he planned to do with the shield that was about to crash against him, transform its weight to a single kilogram with his legs and then throw it away

But it was easier said than done!

The shield was falling at high speed and had already accumulated a large amount of kinetic and potential energy that would be directly transferred to his legs and the rest of his body the moment he touched it. That's why Andrew had to be extremely fast if he wanted to reduce that damage as much as possible.

His timing had to be beyong perfect!!

At the very moment that his feet touched the shield he had to transform it's weight

He couldn't waste even a single fraction of a second!

Otherwise he risked losing his legs, which he needed to escape.

He only had one chance

Pom!

Andrew's feet gracefully touched the shield and in record time, faster than ever before in his life, Andrew managed to reduce the weight of the shield just as he wanted!

'Success'

He had gone through more stress than a bomb defuser, but...

CRACK! CRACK!

However, Andrew didn't notice that David put his 2-ton sword on top of the shield...

"AAHHHHHHHHHHHHHH!!!!"

The weight transformation only applies to things he touches directly. This effect doesn't chain to the things the affected person or item is touching, so Andrew had to carry the weight of the giant sword with his legs.

"AAAAHHHHHHHHHHHHHHH!!!!!

WHAT THE FUCK IS HAPPENING!?

AAAHHHHHHHHHHHHHHHHHHHHHH!!!!

Why is not working?"

Some bones in his legs were broken, but he still achieved the impossible, he prevented that mass of metal from crushing him. He couldn't feel his legs and he didn't know why his tactic hadn't worked or how he was preventing that giant shield from falling on top of him, but one way or another he seemed to have saved the situation.

"Done"

But Andrew was wrong.

What prevented the shield from falling on him wasn't his destroyed legs, but David's shrunken left hand, which a few centimeters from him held the light shield and relatively heavy sword. And meanwhile with his right hand he injects a little of the [Sleeping Beauty] that Fred had lent him into his neck.

He was knocked out almost immediately and David was happy to defeat him with a real ninja weapon

"That skill is dangerous" David said as he picked up and shrank his belongings. "If he had used that skill on me to transform my weight to 1kg, he could have put me in trouble.

He could possibly have handled me too easily, tossing me from one side to the other 

Besides, I don't know that weight reduction would have made me weaker or less dense.

Or worst of all, it could have caused problems in my internal organs due to lack of pressure as Fred once explained

If any of that had happened it could have been very, very dangerous."

Faced with that possibility, David didn't want to take unnecessary risks. That's why he followed the example, teachings and equipment of his teacher to defeat his enemy intelligently.

Like a ninja would do!

No, like a giant ninja would do!

"GOOD!

My first real victory!" David said enthusiastically as he picked up Andrew again, but this time he placed him on the shield, as if it were a stretcher. "And now it's time to go back to the mansion and give this guy to Perona.

"I don't want to miss Fred and Stephen's fights."
