Big-Lipped Alligator Moment: Happens often for comedic effect, especially in the first arc. In the seventh chapter, Cia and Morgan run all the way to Canada to get away from a meme version of "Let it Go" and then shop in EB Games, reenacting a commercial of the store. This is of course never mentioned again.
Cargo Ship: Chrom has an extreme and almost romantic love of fish sticks, leading to them being jokingly shipped by readers.
Character Rerailment: Despite the porter confirming that the entire cast is out of character on purpose, in the final arc, Dark Pit and the other characters start to return back closer to their actual characterization in their respective media.
Crossover Ship: Although this is a fanfic of a crossover game, a lot of the ships involve characters that were never even in the same work together, such as Cia/Robin and Shadow/Shrek.
Jerkass Woobie: Cloud Angelos may be a homophobic bully and a terrible person, but his father is emotionally and physically abusive.
So Okay, It's Average: Since the HTK is parody of almost every trollfic trope imaginable, it's going to mimic something along the lines of So Bad, It's Good, like the majority of trollfics. However, some readers argue that while it replicates and utilizes trollfic tropes very well, it isn't something too much to write home about. However, the final arc tends to vary from reader.
