"Henshin!"

As Tendou raised the Kabuto Zecter, he attached the Zecter to his belt, which caused it to glow.

- Henshin! -

From the belt, multiple small hexagons began forming all over Tendou's body which soon formed a black bodysuit. Then, his suit formed a heavily bulky armor with the colors of silver and red. Oh his hands were silver gauntlets and silver plates could be seen from the end of his gauntlets to the top of his arms. Silver shin plates formed on his legs with armor covering his ankles as well. His visor was blue with a pair of ZECT's insignia on both of the armor on his shoulder.

Once the transformation was complete, the Zecter released a blast of energy, which pushed Rayleigh back a few steps while the Worm shielded its eyes. As the Worm lowered its arm, it flinched at the sight of Tendou's new form as it hissed. "You...how did you get the Rider belt?! I thought I destroyed it!"

Tendou scoffed. "I don't remember you coming near me for the past few years. This belt and I share a long relationship. And now, it is a part of what I must do."

"I'll kill you!" The Worm cried as it pounced onto Tendou, who merely sidestepped the Worm with his right arm stretched out, hitting the Worm's torso before pulling his arm back to strike its back.

The Worm stumbled forward and it quickly turned around, only to receive a fist to the face by Tendou, who then pulled out a weapon from behind his back which resembled a larger sized pistol, with a sharp blade at the bottom at its hilt glittering as Tendou pulled the trigger. The weapon blasted three bullet-like projectiles that struck the Worm's left shoulder and cheek, which made it flinch and fall on its back.

"Tendou..." Rayleigh watched on as he gazed at the weapon Tendou held in his hand as well as the strange armor he wore. All these...from a bug that came from nowhere? He found it hard to believe but yet, it was right in front of him, fighting against a creature even more strange than the armor. But what could he do? Tendou had told him to stand back so that he could battle the Worm himself. And to see him battle a monster, who defeated fifty Marines in an instant, and was gaining the upper hand, the ex-pirate wouldn't bother to interfere.

As the Worm got to its feet, Tendou grabbed it by the shoulder and tossed the Worm onto the ground, where it tumbled onto its side before turning to Tendou and fired web-like projectiles from its mouth.

Using his Observation Haki, Tendou was able to see the Worm's actions before it had done it. Tendou fired his weapon once more, hitting the Worm's projectiles with ease using his own.

"You bastard," the Worm cursed. "You're with ZECT, aren't you?"

"ZECT?" Tendou repeated. "As if I would ever join those liars." He approached the Worm and flipped his weapon around, holding his weapon by its gun barrel, which made it looked as if he was now holding an axe.

The Worm hissed and swung its claws at Tendou, who deflected them with his weapon's blade. Then, in the next moment, Tendou slashed his weapon at the Worm's arm, which caused sparks to fly in all directions as the Worm flinched in pain.

Rayleigh was impressed. Despite the heavy looking armor that Tendou now donned, he was still able to hold against the Worm for a long time, and he was also able to deal blows to it as well. Rayleigh was now convinced that he was perfect to be in Luffy's crew.

With another blow from the weapon, the Worm was now on his back, against the ground. Tendou pressed the weapon's blade against the Worm's neck. "Any last words?"

The Worm smirked as it raised its foot, knocking Tendou off of it as the Worm activated its Clock Up ability, reducing its form to a flash of blue and orange as it slammed into Tendou multiple times which sent the Kabuto user off his feet as he was constantly knocked all over the place while still being in the air.

Now, Rayleigh was worried. "What kind of ability is that? It's even faster than Soru! Not even my Haki can sense it!"

However, Tendou wasn't anxious. As he crashed onto the ground, the Worm reappeared in front of him again before activating its Clock Up once more. Tendou lowered his weapon and closed his eyes, using his Observation Haki again as he searched for the Worm. Tendou trained himself, pushing through his limits. And he knew all of those times spent on training was worth the time for this moment as his Haki soon found the Worm's aura, which created the silhouette of the creature.

"There you are," Tendou muttered as he opened his eyes. With one swift swing of his weapon to the right, the blade struck the Worm, causing its Clock Up ability to be interrupted, bringing it back to the world's normal pace as sparks flew from its left arm, where Tendou had struck.

Injured, the Worm struggled to get back on its feet, barely managing to get up on a knee. It looked up, seeing Tendou approaching him with a intention to kill. The Worm quickly changed into its human disguise, which was also bleeding from the spots where Tendou had struck. "Please, have mercy..."

Tendou ignored its plead for mercy and raised his weapon. Then, he swung it down, letting the blade pierce through the Worm's shoulder as it screeched. Moments later, it was engulfed in blue flames and exploded, leaving no evidence of its body.

As the explosion cleared up, the Kabuto Zecter detached itself from Tendou's Rider belt, cancelling his transformation as it took off towards the sky.

Rayleigh approached him with a grin. "That was an interesting battle, Tendou. What was that thing?"

"All you need to know is that it was a threat to humanity but it's long gone," Tendou replied, earning a laugh from Rayleigh.

"I guess Luffy-kun was right to have you in his crew. I'd suggest you quickly make your way to Grove 42. That's where Luffy's ship is at and knowing him, he's probably waiting for you," Rayleigh said.

Tendou nodded and he made his way towards the direction of Grove 42 before turning his head back to face Rayleigh. "I didn't accept his invitation. But I guess I'll stay on board for a while. They might come into some trouble eventually."

"You're have quite the knowledge about Luffy-kun," Rayleigh said, impressed. "But this is Luffy-kun were talking about. I'm sure he'll be bugging you to stay and join his crew."

"I'll keep that in mind," Tendou replied.

ZECT Branch of Sabaody Archipelago:

Tadokoro and the other ZECT members were all staring in shock at the scene they were witnessing. Their base, that once was their home, had collapsed and had killed everybody inside. Marines who were in nearby Groves were alerted and had rushed in, confirming that no one had survived as they covered each of the bodies they had retrieved from the remains of the base.

"Misaki," Tadokoro spoke, gaining the attention of his colleague. "Get me a Den Den Mushi. Headquarters has to know what happened." Misaki nodded, walking away as she made her way towards one of the Marine Captains who was speaking to his fellow Marines. Tadokoro then turned to Arata and Platoon H and spoke to them. "Search the remains. We have to retrieve the Rider belt at any cost!"

"Yes, sir!" Roared the ZECTroopers of Platoon H as they began their search while Arata stayed behind with his superior.

"Is this what a Worm is capable of?" Arata asked.

Tadokoro shrugged. "It really depends on the Worm itself. They can be intelligent enough to form plans, or they can just attack head on. But judging from the Worms' activities and behaviors, the Worm who destroyed the base was just following orders, probably that albino. All I hope for is that we find the Rider belt. There's a chance that we might still be able to find out who Kabuto's user is."

"When we find Kabuto's user," Arata said. "We'll give him the belt and he'll help us battle, right?"

"If he isn't like the one that Headquarters had selected, then yes," Tadokoro replied as Misaki made her way back to them with a Den Den Mushi in her hands.

Misaki handed the Den Den Mushi to Tadokoro and spoke. "I've managed to get one that links you to ZECT HQ, Tadokoro-san. I hope they'll go easy on you for this incident."

Tadokoro sighed. "I doubt it..."

As he picked up the Den Den Mushi, a voice came through it. "This is ZECT HQ. Why did you call us?"

"This is Tadokoro of Sabaody Archipelago ZECT," Tadokoro replied. "I have...bad news for you, Mishima-san."

"Explain," Mishima replied.

Tadokoro sighed. "It seems that the Worms have proven to be much more threatening than before. They've managed to ambush my men and killed the whole of Platoon L. They've also managed to kill your candidate for Kabuto and while that was all happening, they've managed to send one of their molted Worms to infiltrate our base and destroy it. Our dead consists of the mentioned Platoon L, the candidate, and the rest of my men excluding Platoon H. We are currently searching for the Rider belt that we have left in the destroyed base and are awaiting further instructions."

An irritated sigh came from the Den Den Mushi before Mishima spoke again. "I can't believe that they've become this dangerous. I'm very disappointed in you. Retrieve that belt at any cost, Tadokoro-san. That candidate I selected was useless, as it seems. It's time we find a new one. Gather the remaining of your men and head to Dressrosa. We've been unable to get any words from Shadow lately. We fear that they've been found. Make your way there and wait for your next instructions and send anyone from your remaining members to the branch at Fishman Island. We were hoping that the candidate would come by Fishman Island to pick up something but since he's dead, we'll need you to get it and bring it to Dressrosa."

"Understood," Tadokoro replied as the line went dead afterwards.

"What did HQ say?" Misaki asked as she was handed the Den Den Mushi.

"HQ has instructed us to make our way to Dressrosa to check on Shadow," Tadokoro answered as he adjusted his tie. "It seems that HQ hasn't been receiving any words from Shadow and we're instructed to head to Dressrosa to wait for our next instructions, probably hep find them. And I'm sending you and Arata to Fishman Island to collect something from the ZECT branch there. "

Misaki raised a brow. "Shadow? They're ZECT's elite fighters. If they're in trouble, then I'm guessing that the Doflamingo case must be serious. And for me to go to Fishman Island with Arata? You're kidding, right?"

"Either that or Worms are interfering," Tadokoro replied. "ZECT members who were once part of Cipher Pol managed to find quite a lot of info about slaves and Worms being in Doflamingo's island. ZECT sent Shadow to infiltrate the Worms and prove that Doflamingo is keeping slaves. That is their mission. But to lose communication, I fear for their safety. And no, I'm not kidding when I say that you and Arata need to go to Fishman Island. HQ's orders are absolute."

Moments later, Platoon H's leader soon walked up to them with the Rider belt in his hands. "Tadokoro-san. We found the Rider belt. But the Marines who found it said that it was broken. However, it looks as if nothing had happened to it, even when it was crushed under the weight of the base when it collapsed."

Tadokoro nodded and grabbed the belt. "The Rider belt is one of our most mysterious weapons. Its creators had somehow managed to make the belt self-regenerate over time, which we should find impossible since the top scientist, Dr. Vegapunk wasn't able to make something like it. But we do not question it since the ones who created the belt are also the people who knows more about the Worms than anyone else."

"Tadokoro-san," Misaki said. "Aren't you a friend of the people who has knowledge of the Worms? Because I remember the last time we were in HQ, you were discussing with Mishima about them and he said that you were a-"

"We'll talk about it some other time," Tadokoro interrupted as he handed the belt back to Platoon H's leader. "Tell the rest of your Platoon to assemble at Grove 60. We'll need to borrow a warship and sail to Dressrosa to await further instructions from HQ. Also, we'll need a coated ship for Misaki and Arata."

"Yes, sir!" Saluted the ZECTrooper as he walked back to his Platoon.

Grove 42:

As the soap bubble coating of the Thousand Sunny began to expand, the Straw Hats could only stare in awe as the bubble engulfed them, not even popping as it did so.

"Listen up, everyone!" Nami spoke. "The coating can reduce any level of water pressure, so we need an airbag underneath the ship to keep us floating. Once it's removed, the buoyancy drops and the coated Sunny will sink towards the ocean floor. That who it works."

"I see..." said both the Captain and the First Mate as they stared out towards the Grove.

Nami's brows twitched as she folded her arms. "You obviously don't understand. So, how long is this 'new nakama' of ours going to take to get here anyway? The Marines will catch us if we don't hurry."

Unfortunately for them, the Marines had reinforcements. Three more warships were approaching their way from their back, firing cannonballs at the Sunny.

"They're attacking from behind!" Chopper cried.

Sanji grinned as he leapt off the mast and into the air. "I'll handle this..." With a swing of his foot, one of the cannonballs was sent crashing back at the warships. "What do you think of that, Nami-san? Do you see how much I've matured?" Sanji thought as he looked towards the Navigator's direction, only to catch a glimpse of her pair of treasures and, not regretting it, suffer another nosebleed as he slowly plummeted towards the ship's deck.

"I got him!" Usopp cried as he stretched out his hands to catch the Chef. "Damn it...I hope this new guy's worth the time we're wasting!"

Franky soon got onto the deck, soaked. "I've removed the airbag! Now all we have to do is wait for the new guy!"

"Ah!" Luffy cried. "I see him! He's here!"

The rest of the crew, excluding Sanji, rushed over to the railings, where they spotted Tendou running towards their ship. As soon as he was at the edge of the Grove, Tendou leapt, passing through the soap bubble coating as he tucked himself into a ball and rolled onto the deck before getting back up and dusting himself off. "Looks like I made it."

"You sure took your time," Zoro said, folding his arms.

Luffy gave the Swordsman a toothy grin and petted his shoulder. "That's alright. As long as he's here, we can leave now! Welcome on board the Thousand Sunny!"

"Unfold the sails!" Nami cried, earning confused looks from the crew as she began to explain to them the reason. "I figured you guys wouldn't know what it means. A coated ship catches the ocean currents like wind, and moves with them."

"So we won't get there just by sinking?" Usopp asked, earning a nod from Nami.

More cannonballs were soon fired at them and Zoro was about the unsheathe his swords when Tendou stepped forward and leapt up, swinging his foot at it, coating his foot with Haki as he smashed each of the cannonballs into pieces which made them explode as he landed back on the deck, turning to see the awestruck faces of the crew. "So, should we be going now or what?"

"That was awesome~!" Both Luffy and Chopper cried.

Zoro smirked. "Huh? Another guy who kicks? This should be interesting."

Franky had gotten into his signature pose again. "That was SUPER~! Nice work, new guy!"

"Very impressive," said Robin.

Nami and Sanji simply smiled, until Sanji began gasping for air and twitching uncontrollably. "Sanji! What's wrong?!" Usopp asked.

The Chef calmed down and turned to Usopp, panting heavily as his cigarette fell out of his mouth. "I have no idea. All of a sudden, it felt like someone was crushing my heart."

"Anyway," Nami sighed. "Are the sails ready?"

As she looked up, she spotted both Brook and Zoro at the top of the sails with ropes in their hands. "We're ready at anytime!"

"Good," Nami smiled before turning to Luffy. "Just give the order, Captain."

A grin formed on Luffy's face as he turned to his crew. "Well then, you guys! There are a loads of things I've wanted to talk to you about. But for now, I'll just say thank you for going along with my selfishness for the past two years!"

Sanji lit another cigarette and looked up at Luffy. "You're talking as if we've never dealt with your crazy whims before."

"You got that right," Usopp laughed. "You're always like that, Luffy. Now the only thing we can hope is for the new guy to handle it as well."

Luffy nodded with a chuckle. "Alright then, unfold the sails! We're setting sail now! Onward to Fishman Island!" With that said, both Brook and Zoro unfolded the sails, causing the ship to begin submerging itself under the water.

Grove 39:

The albino clenched its hand, savoring the joy it was feeling as it held the destroyed Rider belt in its grip, not knowing that it is a fake. The albino turned to the other Worms and smiled as it changed into its pirate disguise. "Well done, my friends. We've managed to prevent ZECT from getting a step ahead of us. Without the Rider belt, they won't be able to destroy more of our brethren for a long time."

As the Worms, all still disguised as ZECTroopers, saluted the albino, it continued. "Now the only thing that's left is for the weakling to destroy the base of ZECT on this pathetic island."

"You won't have to wait any longer, sir," said a Marine, who walked pass the disguised Worms to greet the albino as he reverted into a Salis Worm before continuing his speech. "I was at Grove 46, where I saw the Worm your talking about. And I have some...terrible news for all of us."

The albino narrowed its eyes at the Worm. "What kind of terrible news?"

"It seems that you didn't destroy the Rider belt," the Worm replied, eyeing the fake belt in the albino's hands. "Sir, you have destroyed a fake Rider belt. The real one, however, is in possession of a human, who has successfully transform into Kabuto and killed our comrade. However, I do have some good news as well. Before being killed by Kabuto, our comrade was able to infiltrate ZECT's base and destroyed it, including most of the ZECT members inside of the base, which numbered more than half of the entire ZECT on this island."

Hearing this, the albino was conflicted with mixed feelings and it couldn't decide which one was it feeling more. "I can't tell if I should feel glad or disappointed in him. To think that he would be killed so easily even when he had molted. But at least he was able to do something right for a change. I guess he wasn't much of a weakling after all."

Then, the albino took a deep breath and faced the ocean before it smiled. "Now that ZECT is no longer functional on this island, there's no need for us here. Come on, boys, we're heading to Fishman Island!" As the Worms all reverted back into their true forms, the albino did the same before it leapt into the waters, followed by its other molted Worm, and the other Worms.

"Whoever Kabuto is, I'll be sure to kill him..." Thought the albino as it dived deeper into the water.

A/N: Well, this was shorter than the others but I hope it was enough for you guys.
