An asteroid just hit Vlad, flinging him into a natural ghost portal unknown to him and blacking him out. The next day, he woke up to find himself in an Observant courtroom, in an anti-ghost containment chamber, so that he couldn't phase through it.
"Silence in court! State your case Observant 5012!" the judge Observant exclaimed. "Yes, your Honour! Vlad is guilty for these following reasons. First he hires professional ghost hunters to hunt us down and to shame Danny Phantom into hiding. His plan succeeds into making Danny give up his powers. Then he demands 500 million dollars and to rule the world to stop the asteroid, which, he himself caused to move to Earth. On top of that, he didn't even try to fly back and turn the world intangible! He must be put behind bars!"
"How do you plead, Vlad Plasmius, a.k.a Vlad Masters?" "Guilty of course!" Vlad exclaimed. He turned himself human and escaped from the chamber and the courtroom. "Hmm… according to my knowledge of the ghost zone, this passage should lead to Clockwork's private study. Aha, here we go. Let's hope he left his staff somewhere here."
He searched the room and finally found Clockwork's staff. "Yes! Finally the Mastertime is mine! All the power of Clockwork's in my hands! I've waited for this moment my entire life! Now, on to the past, to the moment my troubles began, when I met Jack Fenton, 35 years ago!" He twiddled the knob on the staff and disappeared. Clockwork then came out from his bathroom and spoke into his special medallion. " It is time, Amorpho. Slip it on him now."
In Amity Park, Danny Phantom was fighting Skulker, unknown to him that 'Skulker' was Amorpho in disguise. Amorpho then received the message and threw time medallions on Sam, Tucker and Danny. "What are you doing with Clockwork's medallions?" Danny questioned. "Saving your life", Amorpho replied, reverting to his normal self and flying off. "What just happened?" Sam exclaimed. "I don't know", replied Danny.
Back in Clockwork's room, Clockwork whisked the trio back 35 years earlier. "This is the last magic I have. Now, they're on their own."
