  • Recommended by: Witchfinder, Crossover-Enthusiast
  • Comments: Already well established in other fandoms like Steven Universe and The Loud House, check them out for nice, in-character one-shots and slice-of-life pieces.
    • Seconded. They offer a great look inside the characters and really know how to pack a punch into emotional scenes.

Ask Lakewood Darrell

  • Recommended by: Crossover-Enthusiast
  • Comments: An ask blog focusing on a Darrell who decided to turn tail and work at Gars', where everyone but K.O. (and Carol to some extent) is suspicious of him. Great characterization for Darrell and a wonderful artstyle.


General Fics

Stories which primarily focus on the normal adventures and lives of the cast. Plot-focused stories or light day-in-the-life stories. Pretty much anything that isn't focused on romance.

Lost by Silvers Little Angel

  • Recommended by: Glitter Cat
  • Status: Complete
  • Synopsis: Lord Boxman has lost it all. His home, his job, everything. And to his own robot no less. Now left out on his own during a stormy night, he can only think of how much he has lost because of this whole ordeal. And how he really is, as the other villains say, a "joke villain". Thankfully... there will be a small light to save him from the elements. And his own mind even.
  • Comments: An excellent look at the friendship between Lord Boxman and Professor Venomous, and a great insight into Boxmore's feelings following the Season 1 finale. AO3 link.

Robotic by Silvers Little Angel

  • Recommended by: Glitter Cat
  • Status: Complete
  • Synopsis: Sequel to "Lost". Things have been peaceful since Venomous took Boxman in. Apart from a few things, like the professor trying to make Boxman a new red eye, and having to watch the Boxman as he recovers. Despite this, Venomous is determined to try and help Boxman in anyway he can. Despite finding himself with more questions than answers in multiple areas. AO3 link.
  • Comments: Another great story with excellent characterization for Prof Venomous and Lord Boxman (and a little cameo from Fink.)

Denny's Eggs by bisuroh

  • Recommended by: Infinity League
  • Status: Complete
  • Pairings: Boxman/Venomous
  • Synopsis: "This is a story about loss. A loss of FUCKING brain cells because by the end of this fic my babes Box n’ Ven only have one left and somehow manage to fucking share it. You, my precious reader, are in for a wild fucking ride."
  • Comments: This story is non-stop hilarity from start to finish. It takes a basic premise (Boxman and Venomous get high and go out for a night on the town. Hilarity Ensues) and runs with it, creating some amazingly funny dialogue and scenarios that you could actually see the characters going through, despite how adult and vulgar they are compared to the show. The author does a great balancing act of having Boxman and Venomous behaving in-character while simultaneously doing and saying things you'd never expect from them. Also, the entire story is narrated in a snarky, irreverent, deliberately unpolished style that just ties everything together.

Shipping Fics

Stories focused on the romantic relationships between the cast.

Alternate Universe Fics

Stories where one or many plot points or characters are significantly different from canon.

Hanahaki AU by SneaselXRiolu

  • Recommended by: Infinity League
  • Status:
    • KO's Ask Blog: Complete
    • Unfinished Business: Ongoing
  • Synopsis: Rad, K.O., and (a reluctant) Mr. Gar set up a question and answer on request of K.O. . Each suffer from hanahaki. Will they find their happy ending or will the hanahaki take their lives?
  • Relationships: K.O./Dendy, Carol/Mr. Gar, Enid/Red Action, and Boxman/Venomous
  • Comments: A fun, charming little series that diverts from canon around late Season 1 by establishing that K.O., Rad, and Mr. Gar (and, as eventually revealed, several other characters) suffer from Hanahaki disease note  The author does a great job establishing the concept for those uninitiated, and the deviations from canon make for a very intricate and fascinating experience. Of note is how the story is driven forward via Audience Participation. Readers leave comments to be read aloud and responded to by characters in the very next chapter, and while these interactions started out as simple questions about how Hanahaki has affected the characters' lives, the commenters (or, as they're known in the story, "The Askers") take on lives of their own, becoming characters in their own right and showing the ability to bend the reality of the story's world to their whim. All the while, the author does a fantastic job keeping the characters and setting consistent with the actual show.

Crossover Fics

Fanfiction that combines elements, characters, etc. from two or more different franchises.

Dendy-Wendy Swap by CartoonConshmiracy

  • Recommended by: Forceofnatureandcorn
  • Status: Hiatus
  • Crossover with: Gravity Falls
  • Synopsis: With a strange device created in Dendy's backpack, K.O. gets to find out what life would be like without one of his closest friends, and with a mystery solving kids' red head crush! What changes when these two rhyming name characters swap lives?
  • Comments: A very cute and interesting story of very different (yet similarly named) characters Dendy and Wendy, with everyone very much in character and a good amount of interaction.

Dark Fics
