(A/N- I am not interested in giving most CP0 agents' names, so I will just give them a simple nickname.)
While Chopper's battle was going on, the others also engaged in their battles.
The battle between Robin, Vivi, and the CP0 agent might not have been the bloodiest, but it was the biggest.
The sheer size of their battle forced them to transfer to a whole new island.
Vivi had transformed the entire ground into sand while Robin was surrounded by a Sand Armor while using her powers.
Because she must make a gesture while using her power, Vivi used Sand Armor to protect Robin from the CP0 agent.
Because this agent wasn't a normal agent.
With the high-level mastery over Armament Haki, Observation Haki, Six Styles, and a Devil Fruit, he was a foe that they couldn't defeat easily.
Tori Tori No Mi- Model: Griffon Vulture
This fruit gave him flight, enhanced strength, speed, regeneration, and sharp claws.
Because of this, Vivi had to carefully protect Robin while fighting the enemy.
Of course, Robin also had a job. It was to pin down the Bird Agent.
"Vivi, now!"
Robin shouted as she clutched her fingers. At this moment, two large hands appeared behind a silhouette and pulled up his wings.
The Bird Agent didn't sense this, but his instinct helped him maneuver in mid-air. He instantly changed back to his human form and used his hand to destroy Robin's Arms before changing back to his Bird Form.
Then, he rushed away from Vivi and Robin while planning his next move.
"Argh!"
When he destroyed Robin's arms, he also inflicted some damage to her real body, causing Robin to feel pain.
"Damn it! Are you okay, Robin?" Vivi's expression changed when she heard Robin's cry as she quickly turned around and asked.
"I'm fine. Don't lose your focus, Vivi. This agent is highly skilled at using his Devil Fruit. We mustn't let him get near us while being distracted."
Robin shook her head and spoke with a serious tone.
She underestimated the agent, as she didn't even expect him to change his form in mid-air.
"Right!"
Vivi nodded.
She also understood her opponent. Although they hadn't fought much, they had exchanged blows.
Robin had learned both Armament and Observation Haki. Vivi had also learned both types of Haki.
But unlike Robin, she couldn't use her Armament in her sand as she wasn't an expert at that.
But their opponent had not only mastered two types of Haki but also had a speed advantage against them.
This made him a dangerous enemy to fight.
"Robin, if this continues, we will lose our stamina before him. I am going to use that trick." Vivi spoke with a gloomy expression.
Robin also understood what she going to do, but she couldn't stop her. Because Vivi was constantly using her Devil Fruit, she would run out of energy quite soon.
Once that happened, it would be hard for her to protect Vivi while fighting the CP0 agent.
[Multiple Sand Eyes]
Vivi closed her eyes and released several Sand Eyes on different corners of the island. Because she was using different Sand Eyes, she was getting multiple visions at once.
At first, she almost overloaded her brain, even getting a nosebleed.
But a few seconds later, she began to control her visions and carefully watch every part of the island with her powers.
In less than ten seconds, she saw the Bird Agent resting on the tree while carefully staring at Vivi and Robin.
"There you are."
Bang!
Suddenly, the ground beneath the tree began to change as it turned into sand, and a massive hand emerged from the sand.
[Sand Grip]
The massively growing Sand Hand caught the Bird Agent before he could escape.
"Robin!"
Vivi shouted.
At this moment, several thousand petals appeared above the Bird Agent. These petals turned into a massive hand.
The hand began spinning the drill as it moved forward.
[Thousand Flowers]
[Giganto Riffle]
As soon as the Bird Agent saw that, he instantly realized he couldn't escape the bindings of the sand in time to dodge the attack. So, he decided to play defense.
[Armament Haki- Full Body Armor]
[Tekkai]
Bang!
The massively spinning fist struck the Bird Agent, covered in sand, and smashed him to the ground.
Crack! Crack
The ground began to shake and crack as the Bird Agent got smashed several inches below the surface.
"Too far, Vivi! I couldn't use Armament Haki. That agent used Armament Haki and Tekkai at the same time. My attack shouldn't have done much damage."
"You are right, Nico Robin."
Suddenly, a voice came behind them, which startled both Robin and Vivi.
"What?"
Vivi turned around and saw the Bird Agent standing behind Robin. His body resembled a half-human, half-bird form, where he seemed to have grown wings behind his back.
His face was no longer covered with a mask and had changed into the face of a bird with some human resemblances, like eyes and ears.
"How could you be so fast?"
Robin gritted her teeth and asked, sounding surprised and fearful.
"What made you believe I wasn't fast? My main strength has always been speed. I just waited for you to attack so I could get behind you."
"Just as I expected, once you attack, it takes you some time to recover. Now, it's time for you to die!"
The Bird Agent's fingers turned into claws as he coated them with Armament Haki and pierced forward.
His claw moved like a speeding bullet and pierced through Vivi's Sand Armor.
Before Vivi could do anything, his hand had already pierced Robin from the middle.
At first, the Bird Agent had a cruel smile on his face, but that smile changed into a look of disbelief.
"How is this possible? You were just here."
"Was I? Did you assume I was here because I was using my powers from here?"
A voice came from his shoulder, where there was a small mouth. Before he could answer, though, a massive wave of sand flew towards him.
[Sand Waterfall Binding]
The sand slowly turned into a large shackle as it started covering his entire body, except for his head.
"Armed"
The Bird Agent gritted his teeth and covered his body with Armament Haki, forcing Vivi's Sand out of his body.
Because of the Armament Haki, her sand wasn't able to break through.
Now, she could only utilize her Armament Haki to break her sand into his body.
Of course, she didn't need to do that.
"You forgot the most useful ability of my Devil Fruit."
[Sand Vortex]
Instead of releasing another sandstorm, Vivi simply controlled that Sand Binding and turned it into a fast spinning crescent-shaped sand tornado.
This sand tornado not only released sharp sand blades that attacked the Bird Agent, but every time it attacked, it would consume a small portion of his moisture.
Because the Bird Agent was using Armament Haki, her sand couldn't absorb the entire water from his body at once.
[Whirlwind Griffon Strike]
Faced with such a deadly attack, the Bird Agent couldn't stay inside the tornado for long. He poured all of his strength into his wings and started spinning.
His spinning created a massive whirlwind that started colliding against Vivi's Sand Vortex before both dispersed into a large dust storm.
Bang! Whoosh!
As soon as the dust storm was released, Vivi and Bird Agent used their Observation Haki at the same time to sense each other.
The Bird Agent had quite amazing senses, stronger than hers. Using his speed, he managed to catch her off guard and kick her in the stomach.
Bang!
The Sand Armor cracked as she got sent flying due to the impact of that attack.
Fortunately, she was using Sand Armor instead of relying on Logia's invulnerability.
That kick had an Armament coating, which would be devastating for her. Even so, that kick was more than enough to destroy her entire Sand Armor.
Just when Vivi realized that and tried to create another Sand Armor, a sound came from her side.
"I can't let you do that."
Bang!
Vivi subconsciously released Armament Haki into her head as the bird claw struck her head. Although her Haki managed to minimize damage, she was still sent flying into the buildings.
Thud! Thud!
Vivi felt her head buzzing with a thousand sounds. Except for that, she didn't suffer much damage.
When the Bird Agent struck her, she turned her body into sand, which made her invulnerable against the crash.
[Thousand Flowers]
[Giganto Șlap]
A massive hand emerged above the Bird Agent, and before he could get a chance to move, it smashed upon him.
The hand wasn't white as before; instead, it was coated with Armament Haki, making it harder than steel.
Bang!
The hand squashed the Bird Agent like a bug, crashing and destroying the ground into pieces.
Several large chunks of the ground flew around as the gigantic hand dispersed into small petals.
The Bird Agent slowly stood up, dusting off himself while red blood came down from the corner of his mouth.
He wiped it out and said.
"I've had enough. It's time to end this."
