One Piece: The Power System

Baron glared at Rein as his eye pupils flashed red. Rein stare back at him, he had never seen someone so eager to fight except Ace and Luffy, not even Sabo was like this. "Hold it right there, Baron! Weren't you fighting Captain Red Bull not too long ago?"

Cloud had been secretly watching the fight when they clashed, afterward, he left and was suddenly met with the Flagstar pirates. He chased them but they were running from the Malone Family, he ran into them and a conflicted started on who would capture and receive the Insignia.

"Ha! A low tier Bull like him can't match the legendary bull, it was so weak that it only took one hit for me to bring him down!" Baron sneered at Cloud then looked back at Rein who just stood in place saying nothing.

"By the way, can you stop it from raining in here, it already damn cold enough!" Laflaga complained seeing the clouds in the air still pouring out rain. It was too cold to have water on them, was he insane?

"Deal with it, you slippery squirrel!" Cloud chuckled and looked back at Rein and his crew. "You guys took down Laflaga and his crew, so I'll assume that you guys are in possession of the insignia?"

Cloud speculated

"Insignia? What is that, never heard of it." Rein looked around confusingly and Feigned Ignorance.

Cloud's mouth twitched as he whispered.

"Liar!"

"I have no time for this, I just want to head to the grand line after this! Erica, you deal with this Cloud guy, make sure to turn up the heat a bit because it's going to get colder." Erica nodded and looked seriously at Cloud.

"Little girl, do you think you have what it takes, after I beat you, your Captain is next!" Cloud's body turned into clouds then he flew toward Erica as she did the same. The two clashed, with Erica turning up the heat, Cloud was no match, but Erica made sure to stay away from the rain, she knew what it could do.

"Now, it you and me, Hisagi, you stand back! I'm going to see what this guy is made of." Baron grinned and stepped forward. Baron then rushed quickly to Rein, baring his fist, they crushed towards Rein.

Rein didn't dodge and challenged him as their fist collide, this shook the area and cracked the ice!

"What!? Impossible, he was able to challenge the Captain's raw strength head-on!" The two members of his crew were surprised. Cloud looked back for a moment a was surprised himself, he himself and Baron were from the South Blue so he knew Baron's strength.

"It's just as I thought, I really do have some good judgment!" Baron smiled in excitement and began to exude force to push Rein back.

Crack!

Crack

The ground underneath them began to crack even more with two of them going at it.

"Tekkai Ken!"

Rein took his arm back and swiftly punched Baron in the stomach, sending him flying much to everyone's surprise. Baron slammed into the ice wall and it collapsed on him.

"No way, just Impossible!" Hisagi the swordsman of his crew was at a loss, he had never seen his Captain knocked away before!

Suddenly, Baron burst out of the rubble, he looked at Rein and grinned. "Good, you're stronger than I thought, this is really good!" Baron had some strange red aura around his body as his eye pupil turned deep red!

"Uh Oh, this isn't good!" The two crewmen backed away seeing baron's berserker state. Baron pulled out his Axe and charged toward Rein in a frenzy.

Rein sensed something strange and move away quickly on to an ice Pillar. Baron Axe slammed in the last position Rein was in and crushed the ground. "What is that feeling, he can't be using what I think he's using."

Baron jumped and attack the pillar Rein was on but he had already moved away from it. "Stop dodging and let me hit you!" Baron couldn't catch Rein for the life of himself.

"I gotcha!" With that, baron swung his Axe at Rein. Suddenly, Rein's body splashed and turned into clear water-like liquid. Rein's body materialized around and on Baron's body, giving off below zero temperatures.

"Ice Coffin!"

Baron's Body was instantly Frozen to the point where no one could see his facial expressions! Everyone's face changed greatly due to the drop in temperatures, Nami and Kuina had already made a run to the exit before this could happen.

Sadly, Captain Laflaga and his crew were turned into statues, it was already cold outside and with the fact that Cloud made it rain in here didn't make it better. Now Rein used Nitrogen to this extent and made things even more colder.

"H-he can use Ice!? No wonder Laflaga and his crew members from before were turned in ice sculptures!" Cloud understood right away, this crew had some dangerous abilities, one that could use strange Black Fire and one that could use a liquid cold substance. The scary part for Cloud was that they were both Logia type, which was rare in itself.

Rein stood in place before Baron who had been frozen solid, he was in his liquid state, he looked like water but he was actually Nitrogen.

Whoosh!

Suddenly, two missile homed in on Rein, he looked up then...

Boom!

The area around Rein exploded and was sent into flames, the cave shook from the explosion. "I got him, he's dead for sure with those two missile hitting him at point-blank, haha! Dare to freeze our Captain, he was looking to die!" The markmen of the Berserker Pirates shot two missiles at Rein, he had a rifle but decided to use the Missile launcher on his back.

"Rein!"

"Rein"

Nami and Kuina looked on in Shock, he was directly hit by missiles, they thought he was seriously wounded or worse, Dead! However, Rein walked out of the fire with half the side of his body gone, but he began to regenerate as he walked out!

"What!? He came out unfazed, he even healed his missing side!" The Sniper was stunned seeing Rein come out unscathed. Cloud shook his head, of course he would come out unscathed, he had that type of ability.

"Attacking people in the middle of combat, that pretty disrespectful!" Rein sneered under his helmet.

"Let me show you what happens to people who sneak attack me!" Before he could initiate an attack, the ice began to crack around Baron, the ice showed a red l.u.s.ter coming from it.

Crack!

Boom!

Rein back moved back a bit to see what was up.

*Pant Pant*

Baron broke out of the Ice panting, his body was all red as steam was exuding from it. This reminded Rein of WhiteBeard in his final battle against Blackbeard. "I didn't know you had an ability like that, It looks like I'll have to get serious!"

At that moment, Baron's vein began to bulge and pulsate. Erica and Cloud had completely stopped their fight to watch the interesting fight between Rein and Baron. Steam formed around Baron, he was giving off a lot of heat and melted the ice around him.

Suddenly, both his arms expanded outward and so did his upper body, it looked just like how Frieza looked when he first started to transform. Baron's body grew bigger, his c.h.e.s.t popped the armor he was wearing to reveal his b.a.r.e c.h.e.s.t.

Judging from his transformation, Rein could tell he was a Devil Fruit user. He had a humanoid b.a.r.e c.h.e.s.t, with feet has hooves, out of nowhere a large Axe appeared in his hands. The Axe seemed to have been created from Red Energy of some sort. His face showed that of a bull's face, his face exuded red rage stricken eyes.

"Its a Zoan type!" Erica said unconsciously.

"Not just any Zoan type! This is the Mythical type, a Minotaur!" Rein was pretty surprised about seeing someone with Mythical type devil fruit in this place of all places.

"Oh, you can tell what type of power it is, most just think I'm regular bull, haha!" Baron's voice was much deeper this time around. "It seems that you're that annoying type of ability user just like that Cloud guy's type of power, it looks like I'll have use that to beat you then!"

With those words, baron move quicker much than before and smash his Axe towards Rein! Rein could feel it, this was definitely Haki, but how? Rein dodged and appeared on pillar but Baron was already ready to attack him again.

This was a mythical type, it was completely different from the rest, it was faster, stronger, and much more durable. Eating this type would change someone's power completely, it was very well earned to be in Baron's hands.

Rein dodge again a sent a kick toward his c.h.e.s.t, pushing Baron back slightly! "Haha, you're too slippery, and you have some good strength in that little body of yours, but I can do this all day!"

Suddenly, Baron shot a flamethrower out of his mouth! Cloud moved away, he knew about Baron's strange force to attack people like him. Cloud was unaware of Haki as of now, so he didn't know what this force was.

Zzzwoosh!

The area was set ablaze, but most of the ice that Rein let out didn't melt. It was only the ice that had been there before. "Hehe, I know you're still there somewhere, come on out buddy, this isn't over!" Rein walked out of the fire slowly, Erica remained in her same position, she didn't need to fear this fire.

"Hmm, I guess I'll get a little serious, you're not bad, not bad at all." Rein could see that if this guy had proper training then he could become a decent rival in the future. Though his decision-making skills didn't seem to be the smartest, he nevertheless had good strength.

"Not bad, huh? Then show me what you got!" Baron glared at Rein with anticipation.

Rein nodded and took off his helmet, he didn't want it to get damaged for what he was about to do. He could use an even more power Ice attack like that Chill Fire but his crewmates were around. They would most certainly be caught in that attack, it was just too cold.

Suddenly, wing sprouted from Rein body, they looked shadowy mist wings, claws sprouted from his hands as horns came out of his head. One of Rein eyes turn Aqua blue while the other turned orange, his whole face was covered by shadowy mist that had long since engulfed it, only reveal two blue and Orange gleaming eyes.

"What is that transformation!?" Cloud was shocked! What kind of a freak was this? Why did people like this have to appear, he hated it so much, just why!?

Even Erica was surprised, she had never seen Rein transform before, what would she think if she knew that this was only a half transformation? Nami and Kuina's eyes were glued to Rein, they were lost for words, they couldn't say anything!

Baron's eyes went wide, he himself went straight for the full-body transformation instead of a half body. He was a serious person, so he didn't play around with his foes like most people did in some cases. But this was the first time he felt pressure, it didn't make sense to him, it was like something was telling him that he was no match for this guy before him!

"No! I refuse to believe that, I must fight to improve, I don't chicken out!" Baron refused to believe he was inferior and slammed his Axe onto ground with battle intent. He steeled his will, he was no quitter, he burned with fighting intent!

"Here I go!" Rein voice was slightly distorted, it sound unworldly and devilish! With a quick leap, he appeared in front of Baron at Extreme speed. Baron was still looking at where Rein recently was, he just to fast for him, thus he was kicked in the face and sent flying through the wall.

Baron didn't have Observation Haki, he couldn't see or predicted anything of this magnitude.

The mountain shook and threatened to collapse on them at this point, it was just too much rambling going on in this mountain. Cloud's heart fell, he couldn't process any of Rein's movements, no one could!

Rein wouldn't go full body of this form until he could better control his instincts in it. Carnivorous Zoans bring out the savagery in people due to the fruit. This was even worse with Ancient types like the Spinosaurus and so forth. So one could imagine a Mythical type that was carnivore, it would

be hard to contain it.

Baron never came out of that hole, the mountain shook again as rock began to fall from the ceiling. Cloud concluded that baron was defeat in one hit! Rein didn't need to be here anymore for any reason, so he and his crew made a run for it, out of this place.
