Kokonoe: Sometimes killing your family can bring out your inner demons. But be careful as your little brother may come back for revenge. Something these two know all too well.

Ann: Itachi Uchiha, the Clan Killer of Naruto.

Junko: And the Prince of Darkness in the WWE... the Undertaker!

Kokonoe: The stage is set and the combatants are ready...

Junko: It's time for a Death Battle!

Itachi walked around a massive graveyard wearing his Akatsuki cloak. 

Itachi: ... Well... this is a place I did not expect to be...

He kept walking as a mist blew past him. He stopped for a second and closed his eyes before pulling out a kunai at the man behind him. The Undertaker caught his arm and reached for his neck, but Itachi shoved his hand away and kicked the old man back. Itachi then jumped back as they both looked at each other.

Itachi: Another fool trying to take me on...

Undertaker: You've roamed this earth for too long. It is time to feel the wrath of The Undertaker!

Undertaker floated into the air and fired a burst of electricity from his hands. Itachi did what he could to dodge them all before running away. Taker unleashed a fireball at him and Itachi jumped up to dodge it, activating his Sharingan as his hands were already together.

Itachi: Fire Style! Fireball Jutsu!

He unleashed a giant fireball from his mouth and Undertaker shot a fireball from his hands. The impact caused an explosion between them as Itachi slid right in front of a large fountain. He closed his eye once more.

Itachi: Water Style... Water Dragon Jutsu!

The water from the fountain burst out, taking the form of a dragon that unleashed itself onto the Undertaker. Taker got up, his eyes rolled in the back of his head as thunder was heard in the sky. But Itachi wasn't done.

Itachi: Fire Style... Pheonix Flower Jutsu!

Itachi threw a bunch of flaming shuriken and Undertaker went to use his arms to block them. The shuriken flew past him and he looked up to see Itachi striking at him with a kunai. Taker dodged it as Itachi pulled another kunai out of his other sleeve and went to stab his chest. Undertaker caught his hand and dropped to the ground, locking him in Hell's Gate. Itachi tried to get out but Taker already cracked his neck. He let go and the body tuned to a bunch of flying crows. Undertaker immediately realized it was a fake and looked up to see Itachi throwing a kunai at him. He dodged it and saw there was an explosive tag on it. The tag blew up and Undertaker was knocked back. Taker slid on his feet even more pissed off as Itachi landed. 

Itachi: Water Style! Water Fang Bullet!

He unleashed a giant burst of water from his mouth that knocked Taker back, sending him flying into a Tombstone. His hat flew off and he took off his coat, throwing it to the side. He grabbed the tombstone and lifted it from the ground before throwing it at Itachi, who quickly dodged it. As soon as he did, Taker struck the tombstone with lightning and caused an explosion that launched Itachi right into the Undertaker's hands. He picked him up by the neck and slammed Itachi to the ground. He then walked passed him and grabbed a shovel.

Undertaker: Sorry kid, your demise was inevitable. 

Taker went to swing the shovel onto Itachi, but red chakra suddenly blocked the strike and broke the shovel.

Itachi: Funny... you took the words right out my mouth...

A giant skeleton fist came up and punched the Undertaker, sending him flying back again. Taker fell to the ground as Itachi started to get up. He activated his Mangekyō Sharingan as Undertaker looked into his eyes. Once he did, the sky turned red as 27 men surrounded Undertaker. Taker looked at Itachi then at the 27 superstars.

Undertaker: Well don't just stand there. Come on.

The first to attack was Jimmy Snuka, who jumped down at him. Taker caught him and slammed him to the ground. Jake Roberts then ran at him and tried to hit him with a clothesline. Undertaker dodged it as Jake went for another one before Taker hit him with a Big Boot. He took Jimmy and Jake, throwing them at Giant Gonzalez, causing him to fall to the ground. King Kong Bundy then dashed at him, grabbing him and running him into a shed. As Taker struggled to get up, Bundy grabbed him by the hair. Taker grabbed a scythe and stabbed Bundy in the neck with it, pushing his dead body away and walking out the shed with a steel chair. Diesel dashed at him and Taker swung the chair, knocking his head off. Psycho Sid then tried to strike but Taker blocked with the chair and hit him in the gut. Sid leaned forward holding his stomach before Taker smashed Sid's back and broke his spine. He looked up to see Kane, who grabbed him by the neck. He shoved his brother's hand away and unleashed a burst of flames that knocked Kane back. He then spotted a chain on the ground and picked it up before wrapping it around his fist. Big Boss Man tried to hit him with a club but Taker dodged it and punched him with the chain. He then wrapped the chain around the Bos Man's neck and swung him around.

Undertaker: Argh!

He threw him at Triple H before Ric Flair came and slapped his chest.

Ric Flair: WOOOO!!!

That only angered the Undertaker more as he punched through Ric Flair's skull. He saw A-Train and Big Show approaching and unleashed electricity that went straight through their bodies. Kane then came back and they both went for flaming punches. They clashed and Taker punched his chest, unleashing flamed through his body and sending him flying away once more. He turned around and-

Micheal Cole: RKO!!!

Randy Orton hit him with an RKO out of nowhere, smashing his face into the ground. He tried to get up but Mark Henry jumped on top of him and smashed his body back into the ground. Batista then grabbed him and picked him up before throwing him into a coffin. Taker started to get up as the three of them walked towards him. He grabbed the coffin behind him and swung it, knocking all of them into a giant hole in the ground. Edge and Shawn Micheals then went to take a shot but Taker grabbed them both by the neck and hit them with a Double Chokeslam. Triple H came back with a sledgehammer and tried to hit him with it, but Undertaker caught it and elbowed him in the face, forcing him to let go. He took the Sledgehammer and swung it, smashing Triple H's skull in. CM Punk tried hitting him from behind but Taker swung it again and knocked his head off. Undertaker then dropped the sledgehammer as Bray Wyatt went to hit him with a clothesline. He kicked Bray into the ground and turned around to punch Shane McMahon then John Cena. AJ Styles jumped up to elbow him but Taker caught him by the neck. Before he could do anything, Brock Lesnar came out of nowhere and hit him with a Suplex, smashing him into the ground. Brock picked him up and went for an F-%, but Undertaker landed on his feet. As soon as he did, Roman Reigns flew at him and hit him with a Superman Punch. Both Roman and Brock then started stomping at him as Itachi started to walk forward.

Itachi: How pitiful...

Brock and Roman picked him up, forcing him to face Itachi on his knees... when in reality, he was on his knees... looking up at Itachi with blood pouring out of his mouth as no time had passed at all. Itachi closed his eyes and sighed as he activated his Susano'o.

Itachi: You made a mistake going against me.

He went to use the Totsuka blade to stab through his chest. As soon as he did, however, Undertaker disappeared through the darkness.

Itachi: What?

He looked down as a dead arm grabbed his leg. He quickly released Susano'o and cut the arm off with a kunai before jumping back. He looked around as a bunch of zombies rose from the ground. They were all corpses of the Uchiha Clan.

Itachi: ... I see... without me realizing it... he caught me in a genjutsu...

He closed his eyes again as bloody tears started to come out. He opened them again as the corpses burst in black flames. Undertaker came out of the darkness and unleashed lightning from the sky. Itachi resummoned his Susano'o and blocked the lightning with his shield before throwing a giant Magatama. Three books floated around the Undertaker as his aura made a shield, blocking the Magatama and causing an explosion that engulfed the entire cemetery. Once the dust settled, Itachi stood there with his cloak burnt off. His vision was starting to blur, but he noticed Undertaker's body... lying on the ground.

Itachi: Hmph. You were strong... but not strong enough.

As soon as he said those words, Undertaker suddenly sat up.

Itachi: What?

Undertaker started to get to his feet as Itachi took out a kunai.

Undertaker: Never underestimate... the power... of The Undertaker!

Itachi threw the Kunai but Undertaker dodged it and unleashed a claw of darkness at him. The claw stabbed Itachi in the chest and sent him flying into an already destroyed stone pillar. Itachi coughed up blood as Undertaker walked towards him. He went to punch Itachi in the face, but Itachi dodged it and punched him in the gut. Taker took it and elbowed Itachi, causing him to stumble back. Itachi pulled out a kunai and went to stab him, but Undertaker caught his arm and hit him with a darkness-infused punch to the gut. Itachi coughed up more blood before going to kick Taker in the hip, but Undertaker caught his leg and grabbed him by the neck. He lifted him up and slammed him into the ground hard. Itachi tried to get up but his pine was shattered. Undertaker grabbed him by the shirt and looked him in the eyes. With his eyes rolled in the back of his head and his tongue hanging out, Undertaker signaled for the end of this match. He threw Itachi into the air, jumped up, grabbed him upside down, and delivered a Tombstone Piledriver so strong it smashed Itachi's head to bits. Undertaker let Itachi's dead body drop to the ground. He got up and dragged it to a nearby grave, dropping him inside. Flames emerged from it as Itachi's soul was trapped in the darkest parts of Hell. Undertaker's wounds healed as he began to walk away.

Undertaker(echo): REST... IN... PEACE...

Junko: Well... that was a pile of mindfuckery...

Ann: Itachi was a pretty tough opponent, but Undertaker was on a whole other level.

Kokonoe: Right. While Itachi was more agile than The Undertaker, he was much too slow. And even then, Undertaker has plenty of experience against people faster and more agile than himself. 

Ann: Itachi does have his illusions, but that will only slow Undertaker down. Especially since Undertaker has gone up against others with similar abilities to cause illusions and has resisted their effects.

Junko: This doesn't mean Itachi is out of options. He could always seal him in that drunken blade thingy... but last time someone tried the sealing route, Taker destroyed his seal from the inside. This did kill the Undertaker... but then he came back more pissed off than dead.

Ann: And even then, Undertaker has the power to warp reality with his Books of Death. There's no way Itachi even comes close to that type of power.

Junko: He could try killing the Deadman all he wants, Itachi would only be delaying the inevitable... 

Kokonoe: The winner is The Undertaker...
