Well you guys remember Candace Against the Universe right? Well this is the AU version with roles reversed, different scenes and development. Well hope you guy are ready cause it's show time. (PS this is a sequel to Far from home)

A collection of short stories in the same timeline about small moments shared by two characters. Chapters are not in canonical order.

A Human AU in which Perry is Phineas and Ferb's adoptive older brother and Monty Monogram's spymaster (cross-posting from AO3)

Turnpike Tavern es como el hogar de Ferb. El lugar perfecto para fumar, beber y todo los demás que le pueda gustar al británico. Su vida puede no ser tan decente, pero él es feliz. Al menos es lo que él dice. Phineas vive el sueño de estar en la escuela secundaria. Es el primero de la clase, tiene la novia perfecta y es popular. Él dice que es feliz. Él está mintiendo (Traducción).

Perry gets fired. Monogram believes that Perry is innocent but the rest of the department doesn't believe so. Perry has to discover the reason why he was fired and then put an end to end to it, and quick, before he gets in more trouble. Can he put a stop to it, before there is no hope of return?

A surprise visit at work, leads to a grander one for down the line.

Heinz Doofenshmirtz has always held a grudge against his family, which was his abusive and neglectful parents and the younger and his mother's favorite child Roger, who is his brother, and he rather stay as far away as possible from them. However, he is one day invited to a reunion, which could probably be a chance to fix his relationship with them and earn their approval.

Phineas earns his Emotional Bravery patch. (Or: he remembers when the world was taken over by pharmacists, even when the rest of the world doesn't. Isabella included.) — phinabella, canon-divergence

The story starts when it was hot and it was summer. Isabella likes Phineas and is best friends with Ferb. It's senior year of high school and Isabella has a plan to get Phineas to FINALLY notice her. Will her efforts remain unnoticed by Phineas? And what about Ferb? AN: The story starts Phinabella, stay tuned it will end Ferbella.

While taking a break from their usual lifestyles, two friends run into each other (literally) and, over a short time, start feeling things that they didn't know were there the entire time.

Monty accidentally walks in on Vanessa in the shower during one of their "private" visits. However, the daughter of one Dr. Heinz Doofenshmirtz uses this embarrassing situation to her advantage though. And an interesting one that Monty may find himself thankful he was caught in. Monty/Vanessa one-shot. LEMON. WARNING: Features language, smut, PWP.

Part 13 of the beloved fanfiction.

Phineas and Isabella are both still having nightmares from the night of the living pharmacists. They are 15-16 btw. The gang builds a machine that will bring back suppressed memories to stop the nightmares. I think you know where I am going with this.

AU. The Turnpike Tavern is like home to Ferb. It's the perfect place for smoking, drinking, and everything else the young Brit enjoys. His life may seem like a long downward spiral, but he's content. At least he says he is. Phineas is living the high school dream. He's at the top of his class, has the perfect girlfriend, and plenty of popularity. He says he's happy. He's lying. PxF

A few days before the events of "Road Trip", Baljeet decides to take advantage of Phineas's absence to win Isabella's heart with an audacious construction of his own. But we all know how the course of true love runs - especially in Danville.

MOOOOOOOM! Phineas & Ferb are making a Pitch Meeting!

Pero ¿Qué pasaría si de pronto y casi por arte de magia el menor de los Flynn finalmente sintiese lo mismo por ella y deseara estar juntos para siempre? Isabella cumpliría su mayor sueño y todo sería perfecto a partir de ese momento. Sería la máxima felicidad... ¿o no?
