Disclaimer: I do not own Danny Phantom!
Danny brought his fellow Titans back to the hospital room. As soon as they arrived, Sam and Tucker asked them for a full description of the villains and the ensuing fight. The three heroes were only too glad to deliver a blow-by-blow account of the battle with absolutely no embellishment whatsoever. Unfortunately, the story was interrupted by the arrival of a certain evil halfa who took the liberty to teleport directly into the room in a swirling pink vortex.

"Why hello, Daniel," Plasmius said as his vampiric form materialized out of the flash of pink light. "It's good to see you again."

"What do you want, Plasmius?" Danny growled, his eyes narrowed.

"Oh, the usual, your apprenticeship and eventual domination of both worlds."

"You know as well as I do that I'll never join you."

"Even after the tragic accident that deprived you of a family with whom you can find solace?" Danny's eyes blazed at the mention of his family.

"Have you no respect for the dead?"

"I'm partially dead myself, Daniel."

"You know what I mean, Vlad. This offer is a sacrilege to my mother's memory."

"On the contrary; it would be an honor to dear Maddie's memory if I were to adopt her only son and living descendant and take them in as my own."

"I will never join you, Plasmius."

"Very well, then I guess that I'll just have to destroy you for good this time." The elder halfa hit Danny with a pink energy blast that knocked him out of the hospital, and the two of them prepared for battle as they hovered tens of feet above the ground.

"Who was that?" Raven asked.

"Vlad Plasmius," Sam replied. "He's half ghost, just like Danny. He received his powers in a lab accident about twenty years ago. He believed that the accident was deliberately caused by Danny's dad in order to lure Danny's mom away from him, so for the past couple of years he's been scheming to kill Danny's dad, marry Danny's mom, and make Danny his apprentice."

"So he has all of Danny's powers and twenty years of experience using them?"

"Basically."

"What does his human half look like?"

"As a human he's known as Vlad Masters, a reclusive billionaire with untold wealth and power."

"And Danny's been able to stop this guy before now?"

"Yep, we've handled him before on numerous occasions." Sam said with a touch of pride. Outside, Danny had summoned a rectangular ghost shield with each hand and was using them to reflect ectoplasmic energy blasts that the four Plasmius duplicates were sending his way. During a lull in the assault, Danny dropped the shield and made three duplicates of his own. A fierce melee ensued, but luckily it ended in a stalemate that did not involve Danny being severely beaten. Suddenly, The blue-faced halfa disappeared. Danny re-entered the hospital room.

"That was almost too easy," he thought out loud. All of a sudden, Plasmius reappeared in the room alongside a tall man wearing a mask that was unfamiliar to Danny, Sam, and Tucker.

"Slade!" The two Titans shouted angrily.

"That's right, children. And once I have the access codes to your little tower, I'll be able to disarm the security system and attack you at any time." Slade said.

"You'll never get the security clearance," Cyborg boasted. "The Titans Tower database is protected by a 10-terrabyte encryption code."

"A code which one of my employees should be able to crack with no problem," Plasmius announced.

"And who might that be, Plasmius?" Danny asked. A cloud that appeared to be made up of binary code entered the room and coagulated into the Ghost Zone's own master of science and electrical technology. Nicolai Technus floated serenely over the proceedings for a few seconds, then uploaded himself into Tucker's PDA. With his signature evil cackle, he accessed the Internet and disappeared into he World Wide Web. Suddenly, all three communicators began beeping. Danny, Cyborg, and Raven flipped them open to reveal a harried Robin.

"Guys, we have an emergency."

"We know, we know, someone hacked into our database." Cyborg responded.

"How did you know?"

"We just saw the ghost responsible enter the Internet and begin hacking into the encryption code."

"And you couldn't stop him? Even if he's a ghost, it should be no problem for Danny." Robin asserted.

"Danny's currently being tied down by his arch-nemesis, another half-ghost named Plasmius who's much more powerful and experienced than he is." Raven replied.

"Do you have any idea why the ghosts might want to get into our database?"

"Because in addition to the technological ghost, Plasmius is also partnered up with Slade, who wants to use the information to destroy us."

"What? That's not possible! How can Slade still be alive?" Cyborg lifted up his communicator so that on the other end, Robin was able to see Slade waving at him.

"Hi, mom," the villain said sarcastically.

"Shut up, Slade. We'll stop you again; we were able to do it before."

"Robin, Robin, Robin. Can't you see? My new allies are too powerful for you, even if you team up with Danny."

"We'll see about that. Robin out." The three communicators went blank.
