These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse: Many side characters such as Yawning Squirtle, Boulder Dropping Whale, Kel, Metal Sonichu and Bill the Scientist have become favorites among the fanbase.
Fanon Discontinuity: The author is known to Retcon large amounts of the series. It's up to individual followers of the comic whether any (and which) of them caught on or not.
Sonichu #1: Rosechu could have escaped on her own, considering she is just as powerful as the title character. But no, she willingly became the Distressed Damsel.
Sonichu #4: If Chris-Chan hadn't done... whatever it was... that got him suspect of solicitation, this issue wouldn’t even have a premise, let alone a plot.
Sonichu #8: All of it. Whether it’s Sonichu confusing drawings with reality, Rosechu trying to counteract 4-cent garbage’s pornographic drawings with her own pornographic photographs, or Magi-chan’s inability to warn Blake ahead of time the danger he was in, everybody has dropped quite a few IQ points this issue and that’s saying something.
Sonichu #9: Dating Education, starting from the fact that the title concept doesn’t make any sense and only going worse from there.
Memetic Outfit: While she canonically has grey hair and a viking helmet, earlier artwork of Mary Lee Walsh drew just the helmet, making her look like a bob-cut blonde with devil horns. Practically every piece of unofficial art portrays her as such as a result.
Narm: The biggest source of entertainment in Sonichu.
The Scrappy: Sonichu and Rosechu's kids. The children are widely hated by everybody. Even more so than the other characters. This is saying a lot. They may or may not show traits of Creator's Pet as well.
Punchy is hinted to have a crush on Angelica. Then he ends up with Layla Flaaffy.
Bubbles is with Blake. They hide their relationship for no clear reason.
When Reldnahc is about to be cured of his homosexuality, there is talk of him getting back together with Kel. There is no mention of this in earlier chapters.
Tastes Like Diabetes: The Sonees and Roseys, Sonichu's and Rosechu's children especially. In fact, their "cuteness" is so annoying that they're probably the most hated characters.
Villain Decay: Blake goes from being a Shadow ripoff to a generic Stu in the middle of an episode. Then, he hooks up with Bubbles and becomes a Satellite Character to a Satellite Character before being almost entirely written out.
Wangst: Chris-Chan when lamenting on how he can’t get a girl. Reginald Sneasel as well, being a stand-in for him when he was trapped in the Time Void.
