YMMV: Randy Cunningham: 9th Grade Ninja

  • Alternative Character Interpretation: NomiRandy. Is he the Nomicon's consciousness or a replica of Randy's consciousness?
  • Awesome Music: Anytime 30 Seconds To Math gets to play, expect it to be awesome.
  • Base Breaker: Howard. He's either a funny character, or an insufferable Jerk Ass with Skewed Priorities. Not helping with this is part of the fandom's tendency to excuse his worse moments as "just part of his character" while leaping on Randy for the slightest jerkish inclination (though this has lessened recently).
  • Cargo Ship: Randy and the Ninjanomicon. Like with most cargo ships, the fandom has created a Moe Anthropomorphism of the object half.
  • Crossover Ship: Randy and Mabel Pines.
  • Ear Worm: The opening theme.
    • Bucky's "Ninj-Along" song.
  • Ensemble Dark Horse:
    • Julian, the goth boy, is a very popular character within the fandom.
    • Morgan, the leader of "Dancing Fish", is another very popular character.
    • The Tengu has a huge amount of fanart.
    • Theresa is ridiculously popular for the amount of screentime she's had, to the point where there are several Ninja Theresa AUs and other fan ideas with her as the protagonist floating around the fandom.
  • Evil Is Cool: In-universe, Randy and Howard would love to boycott McFist's products but they're just too cool for them to pass up on purchasing them.
    • Slips into Fridge Brilliance when one realizes they'd stick out if they stopped buying things from the most beloved man in town.
  • Fan-Preferred Couple:
    • Randy and Theresa was this originally, but Theresa is now Randy's canon love interest.
    • Heidi and Randy is another very popular couple, as well.
    • Howard and Debbie are often paired together too.
    • Not to mention the most popular ship in the fandom, Randy and Howard.
  • Friendly Fandoms: Thanks to Spiritual Licensee and a popular webcomic called Age Accurate Secret Trio, crossovers are common between this show, American Dragon Jake Long, and Danny Phantom. Also thanks to the aforementioned webcomic, these kinds of stories are commonly tagged as "secret trio".
  • Hilarious in Hindsight: This show starting airing around the same time as Kamen Rider Wizard. Both shows had the Big Bad using the victim of the week's Despair Event Horizon to turn them into the Monster of the Week. The only difference between the two is that the Sorcerer actually succeeds most of the time.
  • Ho Yay: The relationship between Randy and Howard runs close to this a lot.
    • Season two ramps it up by having an episode where Randy gets jealous of Howard hanging out with Bucky (titled "True Bromance") and where they have to take care of a bologna "baby" for science class and bicker over who gets to look after it.
  • Nightmare Fuel: Even if it's not focused on much in-show, the idea that typical high school upsets like breaking up, being bullied or losing friends can open you up to being turned into a mindless monster.
    • Some of the "destroy the ninja" plots are pretty horrifying when you remember they're aimed at a fourteen-year-old - McFist has tried to decaptitate him in multiple episodes, the Sorcerer almost crushed him (not in the figurative sense), one of Viceroy's robots tried to suffocate him by basically standing on his windpipe, he almost got vaporised in one episode (and if his scarf didn't have some sort of miraculous anti-strangulation function, that probably would have gotten him instead)...the list goes on.
    • To a degree, how the season 1 finale is played. Most heroes in shows like this are at least equal to the big villains in power by the time they hit a showdown like this one...but this episode explicitly shows that Randy is enormously, laughably out of his league when facing the Sorcerer. Even when he brings Howard as the Tengu into it, it takes minutes for the Sorcerer to win, and he's about to kill Howard when the First Ninja intervenes.
    • In "Fudge Factory", McFist almost succeeds in destroying the Ninja...via sticking his head in a high-speed industrial fan.
    • "Ninjception" pretty much runs on it, figuratively and literally. The Sorcerer Orb that Randy got at the start of Season 2 invades his dreams and basically puppets his body to the school so he can free the Sorcerer and return the orb. Meanwhile, Randy is trapped in continual dreams of him accidentally destroying the world/killing Howard while Howard continually eggs him to "stick the ball in a hole" (the Orb breaking in the dream is what destroys everything and starts the next one)...then it turns out that dream Howard is actually the Orb's manifestation in the dream and he basically ends up looking like he's been possessed by a demon (slit eyes, floating, horrible neck cracking).
  • Ship-to-Ship Combat: Slowly has been starting between Randy/Theresa and Randy/Heidi shippers.
  • Spiritual Licensee: To some fans, this series is a sequel of Danny Phantom.
  • True Art Is Incomprehensible: No one at Norrisville High understands Jacques's work.
  • Ugly Cute: Barnabutt Jones.
  • What Do You Mean, It's for Kids?: Mrs Driscoll drags around the skeleton of her dead husband!
    • And snogs him.
  • Visual Effects of Awesome: The opening theme song is incredibly well animated. The show itself is also pretty well done for Adobe Flash.
