I do not own Naruto or Harry Potter!
Okay, I am back. Sorry, but I lied, I don't have any reasons to kill Zetsu. However, if you want to know what happened, read and enjoy!
Zetsu noticed, that four blue orbs appeared around Poseidon. However, he couldn't stop his attack, so he just hoped that he would be able to cut trough it. Poseidon evaded the human torpedo and one of his orbs barely touched Zetsu, when he flew near him. The Akatsuki member landed on his feet and wanted to attack again, when he noticed that he couldn't move his body.
'Shit, what happened? I can't move. This fucker got me', Zetsu thought, in a state of panic.
"You lost, when my water senbon hit your plant. When my Ice Guardian touched the water, which remained on you, you became frozen instantly", Poseidon said, touching one of his guardians.
"This four babies can freeze everything they touch, but when you are wet it becomes even easier for me. You lost, because you thought I could only use water. That is why spies are pathetic, you don't have any real battle experience", he said, coming closer to a completely frozen Zetsu.
"Sayonara, Zetsu from the Grass", Poseidon bowed to him and crushed him into pieces with a swift punch.
Hogwarts.
Konan was lying on a bed behind Pein, reading a magazine. She knew, that when Pein was sitting like that with his eyes closed, he doesn't want to be disturbed by anyone. However, she freaked out a little when he suddenly opened his eyes and said, "Zetsu have died".
"Huh? Died? This is unexpected. I thought that he could do it", Konan replied and continued to read the magazine, not caring about Zetsu fate.
"We can do it. 30% is not enough", Zetsu said, appearing from the wall, surprising Konan again.
"I swear, if somebody is going to appear without a warning again, I will kill them", Konan almost yelled at her comrades. Pein and Zetsu only shrugged not understanding her.
"Zetsu, I even gave you a body double and you weren't able to hit Poseidon even once? 30% or not, that is still pretty pathetic", Pein mocked him. He didn't really liked Zetsu, because the plant-man was too close to Madara and that annoyed Pein.
"It doesn't matter, he gave them enough time to get to Grinngots. The original plan was a success", Tobi said, appearing out of nowhere, surprising Konan for the third time.
Grinngots.
Poseidon was looking at the pieces of a man he never saw before. 'Is this some kind of a substitution jutsu? Or maybe a body double? That spy is pretty fast at running away. Pathetic', he thought, when he heard that someone was behind him. 'He is not alone, at least two of them, more wizards?', the Olympus member thought, turning around. He was surprised when he saw black cloaks with red clouds on them.
"What is with this place? Water everywhere. You know I don't really like this environment, it is annoying to fight here", one of the two man said.
"Shut up, Hidan. You are the one, who is annoying", the other one answered.
"Oh, fuck yourself, Kakuzu. Go fight him yourself, I am not in a fighting mood today", Hidan replied.
"What is the matter? Got into a fight with your little sister clone?".
"Kakuzu, don't call her my sister clone, you ugly bastard".
"I am not ugly, girls love me".
"They don't love you, they love your money. And of course you are ugly, you are wearing a mask for gods sake".
"Do you want to die today, Hidan?".
"Oh, come on Kakuzu, you know better than anyone, that I am ready to die anytime".
'Hidan and Kakuzu, more Akatsuki members? I see, their plan was to win some time with that pathetic spy, while this two get here. However, what are those two doing? Fighting each other, are they underestimating me?', Poseidon thought, sweatdropping. He coughed to receive their attention.
"Oh, right we almost forgot about our target", Hidan said, apologizing.
"Don't underestimate him Hidan or he might kill you'.
"I already said it, Kakuzu, I don't mind him killing me", Hidan yelled, charging straight at Poseidon.
'Such a straightforward attack will never work. He runs too recklessly, now even, if his partner attacks, the attack will hit him as well. Are all of the Akatsuki are so pathetic?", the ice user thought, summoning his 4 Ice Guardians. However, he was too late to notice that Kakuzu was doing handseals.
"Wind Style: Cutting Wind".
'What? He is planning to attack me together with his partner? This is insane', Poseidon thought, trying to evade the powerful jutsu. The wind hit Hidan and the place where the Olympus member was standing. Poseidon appeared from the cloud of dust, coughing. He was flying in mid-air, standing on top of his guardians. 'So much dust, I can't see anything, is the one called Hidan still alive?', he thought, trying to find his opponent in the dust cloud. He barely evaded the scythe, which flew at him. However, he wasn't able to avoid Hidan, who came after the scythe and kicked him in the stomach, sending him flying into the floor.
"Now, Kakuzu, end it", Hidan screamed.
In a blink of an eye, Kakuzu appeared near the man lying on the floor and slammed his fist, with his Earth Armor activated, right into his skull, causing massive destruction.
After the dust disappeared, Hidan and Kakuzu was standing in the middle of the room, disappointed. They were looking at the pile of ice lying on the floor.
"An Ice Clone, how sneaky", Hidan said, with a stupid smile on his face.
"He run away. We should leave too", Kakuzu said, disappearing. Hidan picked up his scythe and followed his partner.
Hogwarts.
"Is she still here?", Tobi said, appearing carefully.
"Nope, she said, that she will read somewhere else, without the freaky idiots", Pein replied. He sounded depressed.
"We wonder, who she called freaky idiots?".
"The one called Poseidon run away. Hidan and Kakuzu weren't able to finish him off", Tobi said, completely ignoring Zetsu.
"Zetsu wasn't good enough for this mission. He isn't a fighting type after all", Pein said, seriously.
"Don't underestimate us, Pein", this was the first time, when Zetsu called Pein like that so casually.
"Remember that you are not the only one who has been called a god. We are Zetsu the forest god from the Village Hidden in the Grass", Zetsu said to him. As soon as he finished he disappeared into the floor, leaving Tobi and surprised Pein in the room.
"You did it, Pein. You made him angry", Tobi laughed, leaning on the wall with his arms crossed.
"What was that all about?".
"I don't know, but let me tell you this, Zetsu is probably weaker than we are, but I don't want to fight him. After all, he earned his title of the god fair and square", Uchiha Madara said, leaving the room.
Somewhere in Hogwarts.
Konan was sitting on a bench, reading her magazine. 'Finally, peace and quiet. I already thought that I will never find a place like this', she thought, smiling unintentionally.
"What are you doing, Konan-chan…yeah", Deidara said from behind, surprising the woman once again.
Everyone in Hogwarts could hear Deidara screams.
So, this is it. This is my experiment with Zetsu, lets see how it will turn out in the end. Oh, and don't forget to review!!!
