• Angel Devil Shipping: Put someone who is in the Frank’s gang (angels) with someone in the Morty’s gang (devils), and you get this.
  • Awesome Ego: Victor and, to a lesser extent, Morty. Frank can also count.
  • Base Breaker: Victor. Fan opinion splits between those who plainly love him, those who think he's an hilarious Unsympathetic Comedy Protagonist, and those who consider him an utter scrappy.
  • Designated Hero: Victor. So much. This is actually intentional, as he's a quintessential Unsympathetic Comedy Protagonist.
    • The Frank's gang as a whole come off as more unsympathetic to Victor in the first album. Characterization Marches On, though, becoming more likable.
  • Draco in Leather Pants: Morty embodies this trope. Due to his style and Don-like behavior, some forget how much of a sociopathic kid he is.
    • Victor himself is a downplayed example. He's not evil per se, but he's still an unrepentant Jerkass Spoiled Brat. Fandom downplays his more unpleasant qualities.
  • Ensemble Darkhorse: Frank. Einstein. Jr. So much he has become the center character in the fourth album, as seen here.
  • Evil Is Cool: The "Muerte Chunga" team uniforms in the fourth album. This is acknowledged In-Universe, with Momses wishing Guillotine would have made them their uniforms too. Considering his team's overly pink, strawberry uniform, it's not without reason.
    • Morty is considered this in general.
  • Foe Yay: Any couple listed in Angel Devil Shipping, mostly Frank/Morty, Lupo/Skin and Gus/Quasim.
  • It Was His Sled: Miss Hit is Henrietta's evil alter-ego. No, really?
  • Jerkass Woobie: Victor Von Piro has shades of this. He’s undeniably a spoiled jerk who treats everyone like total crap and only thinks about himself, doing such things like helping the villain to achieve his goal and betraying his own friends by joining their rival's gang. However, those things were done to come back to his former home Miedópolis, failing in both cases. Also, his life really sucks, if you think about it: He has a very embarrassing family, is a Lonely Rich Kid who has No Social Skills; and, to top it all off, he's pretty much the universe's punching bag (although he sometimes deserves it). You want to punch him in the face for being such a jerk, but also feel sorry for the guy, or at least understand him a bit better.
    • To say nothing on Miss Hit. Sure, she's a queen bitch, but being the Super-Powered Evil Side of Henrietta, is not like she choosed to be that. Her Freak-Out after discovering she's still Henrietta only remarks her woobie-ness.
    • Add to that list Flan Hellsing. A monster hunter, he's absolutely pathetic and, deep down, he knows it.
  • Moral Event Horizon: When we first met Morty Vivente, it's pretty clear he's a jerk. But when he hires a minimonster-eater giant spider to eat his own rivals just to ensure his victory, it shows his true sociopathic nature.
  • Toy Ship: All non-canon Minimonster pairings, most of them being Ho Yay.
  • Ugly Cute: Every Minimonster is cute, but Piruja takes this trope to a whole new level.
  • Unpopular Popular Character: Victor Von Piro. Hated In-Universe, loved by the fandom.
  • The Woobie: In Mini Monsters, all characters have moments, but these are the most prominent ones:
    • The most straight-up example is Gus. Despite his cuteness, he's treated like crap by most of the characters. Although it's Played for Laughs, the fact that GUS is the main Butt Monkey (If we don’t count Victor) makes you feel sorry for him.
    • Frank gets this treatment in "El Perfeccionator" with his own Break the Cutie. Ouch.
    • Poor, poor Henrietta. Being an Ill Girl who can't go out home most of the time and having Miss Hit as an alter-ego is really, really sad. She gets better, but still.
  • What Do You Mean It's for Kids?: Seriously, with all the Toilet Humour, Black Comedy and sexual innuendo, it’s surprising that is still considered for kids.
    • Now that the ¡Dibus! magazine has closed, one wonders if it still be considered for kids...
