, this AU drifts into the teen years of the Flynn-Fletcher brothers, managing to blend darker elements with plots that wouldn't be too out of place in canon.
Below is the list of stories in roughly chronological order and the recommended reading order.
- PnF: Timeloops: Ten-year-olds Phineas and Ferb go about their normal day, creating, inventing, and unknowingly bothering their sister. But when an unforeseen incident happens in the year 2014, they get a familiar visitor from six years in the future. No pairings, no slash.
- PnF: Ghosts: Takes Place As Teenagers - Do you believe in ghosts? Whether Phineas and Ferb do is debatable, but Phineas' emotions are put to the test when Ferb suddenly and mysteriously disappears. Little known to everyone else, Ferb's been standing next to them the entire time. T for a few sad scenes and some action. No pairings, no slash.
- PnF: Stolen Identity: Takes Place as Teenagers - Phineas knows something's amiss when his brother starts to become irritable, snappy, and downright rude. When things get worse, Phineas is convinced Ferb has gone completely insane, while the real Ferb tries to fight his way back and drive off the impostor who has taken his place. T for some mild violence. No pairings, no slash.
- PnF: Stuck Like Brothers: Takes Place As Teenagers - Brothers are close, but a backfired project puts Phineas and Ferb a little closer. Fused at the elbow, they stumble about going through a day with three arms. But awkward stares aren't their only issue, when Phineas and Ferb discover a problematic side effect: They are linked by a little more than bones! No pairings, no slash.
- PnF: Mind Trapped: Takes Place As Teenagers - After a mysterious sickness hospitalizes him, Ferb finds himself unable to wake up from a strange dream. Now, he must face this new and lonely Danville, and escape from within his own mind, if he is to return to the waking world. T for some sad hospital scenes. No pairings, no slash.
- PnF: Species is a Constant: Takes Place as Teenagers - Ferb finds out the hard way that sometimes even things as concrete as species can change. Accidentally turned into a dog, Ferb must now figure out how to face life in this new form, as Phineas tries all he can to change his brother back into a human. No pairings, no slash.
- PnF: SiaC: A Visit to the Vets: A one-shot based off of the fanfic: Species is a Constant. A veterinarian receives a strange visit from what she thought was a boy and his dog, who isn't so much of a dog anymore!
- PnF: Lifeleap: Sometimes people change when they get older, it's a fact of life. But ten-year-old Phineas worries he might lose his friendship with Ferb as the years go by. Answers are given to him in the form of a lifeleap, and Phineas find himself on a terrifying encounter with an unfamiliar stranger: a green-haired teenager. T for emotional scenes. No pairings, no slash.
Sols06's P&F Verse contains examples of:
- All Just a Dream: Ferb's side of the action in "Mind-Trapped". Justified by it being the result of a coma.
- Big Brother Instinct: Ferb, full stop. He's furious when he witnesses how badly his replacement treats Phineas in "Stolen Identity" and in "Ghosts", he holds Phineas back from rushing into the burning house (Phineas thought he was still inside) despite being (unbeknownst to him) invisible to everyone.
- Brick Joke: In "Mind-Trapped", the mental construct Phineas responds to the phrase "Round and Round" by talking about "The Wheels on the Bus"; Ferb shuts him down quickly. Once he wakes up, Ferb asks the real Phineas what comes to his mind when he hears "Round and Round". The redhead responds by beginning to sing "The Wheels on the Bus"; Ferb cuts him off and remarks that he knows Phineas way too well.
- Converse with the Unconscious: Phineas does this with a comatose Ferb in "Mind-Trapped"
- Demoted to Extra: Pretty much anyone who isn't Phineas or Ferb suffers this fate though who and to what extent varies from story to story.
- Evil Twin: Ferb gets one in "Stolen Identity".
- Forced Transformation: An invention causes Ferb to become a dog with no way to turn back immediately.
- Gen Fic: While characters other than Phineas and Ferb appear and sometimes play major roles in the stories, there is no shipping of any kind.
- Hope Spot: In "Stolen Identity", the real Ferb manages to interact with Phineas, behaving like his normal self and cheering Phineas up immensely. He steps out briefly...and is replaced by the fake again much to Phineas' obvious dismay.
- Right for the Wrong Reasons: Phineas picks up on "Ferb's" unusual behavior in "Stolen Identity" pretty quickly. However he thinks Ferb is just tired (and later has lost his mind) rather than replaced by an Evil Twin.
- Spot the Imposter: In "Stolen Identity", Ferb is replaced by a double for some unexplained but evil purpose. Said double spends the rest of the story acting so unlike Ferb that Phineas eventually thinks he's lost his mind and becomes completely terrified of his beloved stepbrother...meaning he fails this trope for most of the story. Fortunately he eventually figures out which is the real Ferb and the pair escape, leaving the evil double with the invention he needed Phineas to build for a reason we're never told.
- The Mind Is a Plaything of the Body: Discussed but defied in "Species Is a Constant". Ferb has no intentions of acting like a dog and in fact, spends the rest of the story acting distinctly un-doglike.
- Trust Password: In "Stolen Identity", Phineas does an impromptu one on Ferb's replacement, asking him about the day they first met. Different from the typical example in that the first time he asks this question, he doesn't realize he's talking to an impostor (rather he thinks Ferb's gone mad) and wants reassurance that Ferb is still the person he loves. Later the real Ferb answers the question (Phineas insisted on saving Ferb some cake if you're wondering) much to Phineas' obvious relief.
- What Happened to the Mouse?: In "Stolen Identity", we are never told what becomes of the Ferb impostor, where he came from or why he needed Phineas to build the device he had blueprints for (or what said device does for that matter).
