A few things that are ALWAYS in Dipper x OC fics:

1. The OC is ALWAYS from a 'troubled' background. Usually something involving 'bad parents' or being a 'social outcast'.

2. The OC has ALWAYS got some magical power, from turning into a werewolf, to summoning up MAGICAL FIRE DEMONS!

3. The OC ALWAYS meets Dipper at the Mystery Shack, in a 'cute' way... Like they both drop something simultaneously and bump heads. OUCH!

4. The OC ALWAYS falls in love with this 'strange chocolate haired nerd' at first glance... And the same with Dipper, who INSTANTLY forgets any infatuation he might have with Wendy, Pacifica, Waddles etc... And makes this girl the SOLE OBJECT OF HIS AFFECTION.

5. The OC ALWAYS has Mabel as her Wing Man... As soon as the braced, sweater wearing one sees these two cuties together, her cheeks turn red and her only thought is OMG! OMG! GOTTA SHIP! GOTTA SHIP!

6. THE OC will ALWAYS have romantic rivals in the form of horribly written, out of character girls from the show: For instance, Wendy will forget about 'just being friends' with Dipper and suddenly become a jealous bitch, and Pacifica will lose all the development she got during Northwest Mansion Mystery and regress back into that 'one dimensional, bleached blonde, Valley Girl stereotype' we all love to hate.

7. The OC will ALWAYS get an encounter from Bill, who will convince her to 'do a deal' which involves harming Pine Tree in some way... Cue the OC having a breakdown "WHY WASN'T I THERE FOR HIM?! "And a million sick bags will be filled all over the planet.

8. The OC will suffer a horrible injury at some point, because of an accident that was no-one's fault...Cue Dipper having a breakdown "WHY WASN'T I THERE FOR HER?!"And a trillion sick bags will be filled all over the galaxy.

9. The OC AND Dipper will use overly flowery language to describe each other's physical appearence... The kind of awful dialogue that Alex Hirsch would NEVER allow in the show in a million years. Thank goodness...

10. The OC and Dipper won't actually 'get it on' in the end... Because most of these type of stories will go unfinished. And with good reason... The majority of them are the most appalling soppy nonsense, and besides the authors have got better things to do... Like shovel down ice cream while watching daytime Tv ("JERRY! JERRY!") .

And that concludes my list. I hope you liked it. If not, I don't really care... BUT ****** YOU! ;)
