I decided to make this the final chapter, since there isn't a whole lot of plot left after the final confrontation between Danny and Vlad. However, I also decided to make a trilogy out of this, so you can expect another fic along this theme to come around sooner or later.

Disclaimer: I do not own Danny Phantom or Naruto!

Danny, with his byakugan, caught Vlad's carefully-hidden look of surprise and shock at the younger halfa's new ability. However, the look was quickly covered in the elder halfa's usual smarmy exterior.

"So you discovered a kekei genkai of your own, very good, son," he complemented in a tone that Danny knew was anything but complementary. "However, you should know that you are still not powerful enough to defeat me. Not only have I had my powers for twenty more years than you, but I've had several weeks of practice with my sharingan whereas you can't have had more than a day's practice with those eyes."

"That may be," Danny responded, purposely lying about how long he'd been practicing with the byakugan in order to get Vlad to underestimate him, "but mine are Hyuuga eyes. Your sharingan is believed to have been descended from my byakugan. Your eyes are only an offshoot of mine." Vlad cringed at the condescension in Danny's voice, knowing all too well that he himself used that tone when claiming himself to be more powerful than his younger counterpart.

The two combatants rose into the air and circled each other silently. Danny glared at Plasmius, his byakugan focused on the elder halfa's sharingan eyes. Plasmius' gaze shifted away from Danny and rested on Sam and Tucker for a fraction of a second before moving back up, but to Danny the eyes moved in slow motion, and based on their movement he was able to tell that Plasmius was going to try and attack the two of them in order to distract him.

He was proven correct as Vlad reached out and fired a pink ectoblast at the two of them, but it was blocked by a dome-shaped shield that Danny had quickly conjured around them.

"Nice try, Plasmius," Danny taunted as he dropped the shield, "but you're a little too slow." He shot forward at the man in an attempt to land a quick blow on one of his tenketsu before Vlad had time to react, but unfortunately for him, Vlad's sharingan allowed him to analyze Danny's move and dodge just in the nick of time. Vlad grabbed Danny's ankle as he sped by him and threw the boy down into the ground.

Danny climbed out of the small crater, an idea coming to him. He rushed at Vlad a second time, and again he was grabbed by the ankle. This time, though, he sent a small burst of chakra out of his ankle, giving Vlad minor chakra burns on the palm of his hand.

"Foolish child," Vlad spat as he yanked his hand back with a grimace of pain. "You will pay for that." He immediately duplicated into four, and the duplicates all surrounded Danny. When Danny looked at their chakra networks, he found that each of them all had identical chakra levels. In other words, they were all identical to him.

"Darn," he muttered to himself. "My byakugan can't tell which is the real one." He duplicated into two in order to at least attempt to even the odds, but one of the Plasmius clones immediately destroyed the duplicate.

"Don't you remember from the other day? My sharingan can determine which is the real you," Plasmius stated. The four clones converged on Danny and fired simultaneous ectoblasts at him. Danny screamed, but a second later was enveloped by a puff of smoke. When the smoke cleared, a charred, blackened Fenton Ghost Gabber was in his place.

"A kawarimi?" Vlad muttered to himself.

"Hey, Plasmius!" Danny, who was now floating outside of the circle, called. The four Vlad duplicates all turned to face him. "Take this!" He threw a shuriken from his thigh holster at them, and quickly formed the ram, rat, rooster, boar, and tiger hand seals.

"Shuriken kage bunshin no jutsu!" he shouted as the shuriken formed three shadow clones. Three of the shuriken were struck and disappeared, but the real Vlad protected himself with a pink ghost shield that blocked the shuriken.

"You'll have to do better than that, son," Plasmius taunted, and fired an ectoblast at Danny. However, it was another kawarimi and it disappeared as soon as the ectoblast made contact.

"Oh, I know," Danny replied from up above Vlad. He charged a pair of kunai with his own energy before throwing them down at Plasmius. Vlad moved to dodge, but the kunai caught on the end of his cape and trapped him in the ground. He tried to phase out of them, but since they were charged with ecto-energy, he couldn't. Vlad growled as he tore his cape out of the ground, leaving two large rips where the kunai had been. He stood erect and looked for Danny, but the boy had disappeared. All of a sudden, Skulker phased up out of the ground.

"I was going to give chase to the whelp when I found the two of you fighting. Do you need my assistance, sir?" He asked as several dozen large weapons popped out of ports in his armor. Vlad rolled his eyes and fired an optic blast at Skulker, who became Danny in a puff of smoke, his hands still locked in the tiger seal.

"Did I mention that I can see through henge no jutsu as well? Silly me," he said in feigned ignorance as Danny glared at him. "This cape was expensive…you will pay, Daniel." Vlad shot towards Danny but Danny quickly ducked. As Plasmius passed over him, Danny thrust his palm out and struck Vlad in the center of his chest with a chakra-infused palm. Vlad tumbled to the ground and shakily stood up.

"Wh-what the cheese was that?" He wheezed.

"These eyes allow me to see your chakra network and attack it directly," Danny explained. He brought his foot around in a devastating whirlwind kick. "Konoha Senpuu!" he shouted as his foot made contact with Plasmius, who was too weak to dodge the blow. Vlad got up for the second time, this time seriously worried. He turned off his sharingan in order to save chakra, but he honestly wasn't sure whether or not that would help.

Where did Daniel get such power? He asked himself. Danny concentrated for a second, and several large, glowing-green circles appeared around him with various symbols interspersed around the circles.

"Hakke Rokujuyon Sho!" He shouted, and rushed at Vlad with chakra-infused palms.

"Two strikes!" he struck two of Vlad's tenketsu.

"Four strikes!" Vlad was knocked back several feet as four more of his tenketsu were closed.

"Eight strikes!" Vlad was one step away from coughing up blood from his internal organs being struck with such force.

"Sixteen strikes!" The elder halfa was surprised that he was still able to stand up straight, what with the beating he was taking.

"Thirty-two strikes!" The man could feel that one more hit like that would destroy him for sure.

"Sixty-four strikes!" Danny screamed as he inflicted the final part of his combo. As he finished, Vlad was thrown back about fifty feet. He tried to stand up, but he immediately sank to his hands and knees. He coughed up a small amount of glowing pink blood, then fell forward.

"Very good, Daniel…" he gasped before losing consciousness. Two rings of shadow passed over him, reverting him to his human form.

Tucker and Sam ran up to where they had seen most of the fighting taking place and saw Danny standing over Vlad's prone body.

"Dude…" Tucker said, awed. "You won."

"I…I can hardly believe it," Danny admitted.

"You didn't even have to use your Wail, either," Sam noted. Danny nodded.

"All the better. The last thing we need is for him to see it and copy it with that sharingan." Just then, Vlad's eyes fluttered open and he slowly came to.

"What…" he muttered. Danny immediately placed a sandaled foot on his chest, keeping him trapped.

"I'll let you go once you answer a couple of questions, Plasmius," Danny spat. "First off, how exactly did you get the sharingan?"

"A bit of research," Vlad replied.

"How about a bit more detail?" Danny asked as he drove his heel into the man's chest.

"Very well," Vlad said with a grimace. "I traced my family's history back a few generations, and it turns out that my mother has an ancestor who was an Uchiha, an S-ranked missing nin."

"Makes sense," Danny mused. Suddenly, Vlad whipped a communicator out of his pocket.

"Do it now," he commanded. Immediately, an invisible force knocked Danny skyward with an uppercut as it phased upwards out of the ground.

"Wh-what was that?" Danny asked as he hit the ground and shakily got up.

"An ally," Vlad replied. The invisible assailant made himself visible, and Danny, Sam, and Tucker paled.

"You…" he gasped.

"Me." Standing in front of him was none other than Dan Phantom. The torn bottom edge of his cape brushed against the ground as he walked towards Danny. Suddenly, his eyes turned into those of the sharingan. A second later, they became something entirely different. The iris was still red, but instead of three toeme the pupil looked like a three-pointed star. He grabbed Danny by the throat and hefted him up into the air, so that the boy's eyes were inches away from his own.

"Mangekyou Sharingan," he hissed.

Tucker and Sam watched as Dan whispered something inaudible to Danny. One second later, their friend fell to the ground, screaming.

The End

Again, expect the final third of the Ninja Phantom trilogy (which will be called Ninja Phantom for simplicity's sake) to come out whenever I find time to write it. See you soon!
