Mr. Lancer's Mistake
Summary: It's been a total of 2 years since the portal accident, and Danny Fenton thinks he has his ghost problems situated, until Mr. Lancer votes in favor of the new idea to inform the students on how to be safe when it comes to ghosts and announces to his students of the new ghost class.
(Many of the ideas are inspired from other fanficfions that are in my favorites and I just wanted to attempt my own version. Also, I don't own these characters, or this show PP never happened. Lastly, I don't own the show.)

Chapter 1: How Everything Has Changed
(This is just what happened to the trio sense the accident. PP never happened)

Third person p.o.v.
Danny Fenton has become an even bigger enigma to everyone, other than his best friend's, Sam and Tucker, to everyone at school. He's become more shy and timid, frightened, and has been less talkative. Along with that, Sam, Tucker, and Danny have come close, extremely close.

They depend on each other with their lives. The trio are attached at the hip, doing almost everything together. One doesn't even have to talk for the other to get what they are implying. They have hundreds of conversations with their eyes. Sam's mother has given up, realizing how close her and her friends are, and doesn't pester her about her daughter's irresponsible friends.

Most of every night, they are always together at one of their houses. They stay side by side, enjoying each other's comfort, and have had their schedules changed to make sure it stayed that way.

People stare at them, talk about them. They call the trio freaks, and make rumors about them. They are the outcast in the school, after all.

Now, back to Danny. He has changed dramatically. His body is muscular, having had trained in ghost and human form, and is extremely tall. He slouches in school though, and wears a baggy hoodie and jeans most of the time to hide it. He never talked, wanting to not give away any hints of him being Danny Phantom by accident.

Tucker hasn't changed physically much, except adding muscle to his lean frame and taller stature. Sam is taller as well, and has her black hair down to her shoulder blades. They all have more muscle, and a few scars. Danny's are the worse though.

Maddie and Jack Fenton are still crazily obsessed with ghosts. They are still good ghost hunters, but they definitely aren't the best. Sadly, they have been neglecting Danny and gave up on bringing him back to the boy who was always happy and was amazing in school. Their attention is always on Jazz Fenton or their ghost inventions. It was bitter sweet for Danny, having his parents giving up. Sure, he liked not having their attention so they won't expect anything of him. But, he loves his parents and is depressed they won't even look his way.

Danny's powers have greatly improved over a 2 year period, and he's proud of himself for how much work he puts into protecting Amity Park. But, school's a whole other story.
For him, ghosts come at any moment of the day, simply to create havoc on the world, not just his city. His ghost sense has seemed to be stronger, making him be able to detect a ghost from a few miles away. He can also detect ecto-signatures, meaning he can identify a ghost through his ghost sense.

Ghost attacks are way more frequent. They come any chance they can to hurt the humans, but Danny knows how to protect his home and his world.
Tucker always upgrades his electronics and has some ghost weapons installed to them, like lasers. Sam has daggers hidden in her boots and a long black sword with green markings.

No one but the trio, Danny's sister, Jazz, Vlad Masters, most Ghostly enemies, and Danielle know about Danny's secret life, and he intends to keep it that way.
He had created a Phantom lair as well. It's a medium sized island with a huge black building with a green glow to it. The huge doors to the front have his big insignia that is a D wrapped around a P. It's like a mini castle. Thanks from the help of Frostbite, Danny Phantom now has his own hideout in the ghost zone.

Now since Danny has been in an act for two years, everyone thinks he's this irresponsible kid that doesn't want to grow up and slacks. He is always skipping class and falling asleep. His grades have decreased heavily since Freshman year, and he doesn't complete his homework.

He's now the mystery. Everyone wants to know this mysterious boy's life, even some of the A-listers such as Paulina. He may be the freak, constantly being put down and bullied, but he has this dark and mysterious aura that people are curious about.

Who is Danny Fenton? Why does he only talk to Sam and Tucker? Where does he end up going during class? How does he come into school with injuries so often? What is the enigma of Danny?
