Summary
I was very captivated by the new episode i just watched, “Dooflicated,” a great epiosde that lasted 11 minutes showing the gang turned evil and Candace has to stop them, the stakes were high but not that much.
So, what if it has higher stakes?
This is that story, which was originally going to be a standalone two-shot but I now plan for it to be longer like 22 minutes, also i'm adding some more characters we didn't get to see. -

Summary
Autumn comes to Danville and Phineas and Ferb and friends prepare to enjoy the season to the fullest. Meanwhile, Candace struggles with the decision whether she should keep her summer job as Heinz Doofenshmirtz's intern or go to college, as her mother keeps urging her to do.
However, as shadows seem to suddenly encapsulate the city, thoughts of devising fresh ways to rake leaves or choosing what to go out for as Halloween swiftly fade into that same darkness as friends and loved ones start to disappear and Candace finds that she might not even have a future, as she and her brothers band together to take on the unknown monster threatening them all.
It soon becomes a perilous choice which leads to Candace, at last, coming face to face with the Mysterious Force she feels has been out to harm her all along...

Summary
Extra Hereditary Murphy’s Law: The high concentration of negative probability ions around an individual which causes things to go wrong more than they would for anybody else.
The Murphys always thought that they were the only family who had EHML. Everyone on Earth, and even extraterrestrial races, could be affected by Murphy’s Law, but nothing like what the Murphys had. They had it much worse. Now they're realizing that isn't the truth. Not by a long shot.
When Martin was escorting Milo to school one day, the two Murphys didn’t expect to suddenly stumble upon an evil scientist trying to use his new Inizor to take over the world. When they try to escape, Milo is the only one who makes it out. Now he and his friends have to figure out how to shut down this machine to secure the safety of their entire dimension. To make things even weirder, several peculiar strangers have come to town. On top of everything already on his plate, he has to help them get home before it’s too late.
Fixing dimensional warping, saving the world, finding (and probably rescuing) his dad, and trying to deal with the existence of the multiverse. How can a 13-year-old handle that much? He keeps moving.

This is a story of misinterpretation and miscommunication, of love trapped inside definitions they were too scared to break… and the one time they finally did.

The crew of the USS Enterprise-D are responding to a distress call when they are transported to Danville USA where they meet a pair of stepbrothers who make cool inventions. Together, they will have to face off against the intergalactic criminal known as Mitch.
Or, the Star Trek: TNG / Phineas & Ferb crossover you never knew you wanted (and probably still don't want because it sounds completely ridiculous. Don't worry; it's even stupider than you think).

Summary
Believing that everything in his life could be fixed if he had only become class president in High School, Heinz Doofenshmirtz uses his past invention, the De-Age-inator, to become 18 years old again and quickly enrolls in Danville High. However, in the high school political arena, Doof faces fierce competition from his opponent, a girl named Candace Flynn, whom smells something fishy about the new "exchange student" and soon sets out to bust him!
When the two are paired as soccer rivals and then lab partners, though, their mutual understanding soon works against them and turns their fierce rivalry into something neither of them expected.
Heinz now has to ask himself if he's evil enough to take his daughter's friend to the prom before taking over the Tri-State area, while Candace has to answer, once she gets the evidence she craved, if she's prepared to bust someone she's fallen in love with? And if she'll really be okay this time when everything disappears.
It seems neither teenagehood nor middle agedness is all it's cracked up to be.
