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.
Complete Monster: Doctor Z used to be one, thanks to his Abusive Parents qualities and cursing his daughter to ruin her career over something he didn't like, but this ends up as a subversion, this being a parody series, that Executive Meddling made his personality flip-flop between his old Complete Monster style or basic Evil Overlord style, and he ends up trying to start clean again in the end. In season 2, his fall into monsterdom got a complete Retcon that he's not even having any business with anime, having been a robot developer instead.
The whole plotline about the Akibarangers trying to appeal to Toei to get their own TV show could be considered a minor one of these after it's discovered that they already have one, it's the show you're watching, and the very company they were pinning all their hopes on is messing with their lives for fun.
Nobuo's "so expensively cheap" line in #1 is ringing uncomfortably true now with the prices of the official merch — a working scale MMZ-01 will run a fan $150, while the SH Figuarts Itasha Robo is set to go for $450.
In fact, that very line is being used in advertisements for the Itassha Robo.
The Reveal that the Akibarangers already have a show and it's undergoing a massive retool stops being funny and starts being prophetic due to the fact that their official counterpart is undergoing that same thing. Thankfully it wasn't as drastic as it was in Akibaranger...
The episode where Mitsuki reveals she's leaving the team — only to add that it's for a martial arts camp and that she'll be back — stings a little bit with the knowledge that Kyoko Hinami will not be returning for season 2. The damage is thankfully lessened that she is back for the 1st episode of Season 2, which was explaining why she wouldn't be in the team anymore: Due to massive Retcon, Mitsuki was the one being recruited by the Pentagon instead of Akagi.
Nichijou had the infamous Overly-Long Gag "Hakase de nyan!" "Moe desu!", stringing together three words we hear a lot in this series.
The popularity of Akibaranger had gotten it extended by one ep - which wasn't really in the gameplan, so they're making it a Clip Show. Which of course is done by lots of other shows for padding. It's just ironic that an "unofficial" Super Sentai is getting an unofficial last episode.
Episode 1 had the villains acting under a fake company named for the Marudeyouna Worlds (read: Pocket Dimensions) of Mahou Sentai Magiranger. It's not just foreshadowing the existence of the Delusion World, but the nature of the show itself.
#6. Yumeria is writing a yaoi doujinshi involving someone called Grey.
At an early press conference for the show, Nobuo's actor reportedly asked if there would be Akibaranger Ranger Keys and was quickly shot down. But eventually... it happened!. * Counts as a Defictionalization, but sadly won't work on ANY Mobirates.
Les Yay: In Episode #10 with Hiroyo and Kozkoz, Mitsuki and Yumeira cosplaying Z-Cune Aoi Scene. Then Played for Laughs in #12 when Yumeria tries to shake up the formula for their very reality by doing this with Kozkoz - and it turns out she liked Yumeria for real.
Memetic Mutation: Come the finale, Saburo Hatte has taken Decade's place as the person to blame any time anything goes wrong.
Moral Event Horizon: Malshina crosses it in 2-10. She cruelly uses General Pain to steal his knowledge on Sentai villains and ultimately turns him into a normal dentist. Next, she brings back Delu-Knight... while making him completely subservient and willing to go through anything for her. Oh, and it's implied all this killed Saburo Hatte and wiped Super Sentai off the face of the earth. Wow...just, wow...
And, like many things in Akibaranger, this is revealed to be a subversion General Pain is an Author Avatar of Saburo Hatte, who was severely weakened, not killed. Malshina's true plan was to take his place as the most powerful being in Super Sentai.
Replacement Scrappy: Luna could be seen as such compared to Mitsuki being the Only Sane Girl and being into martial arts which provides good fight scenes. In comparison, Luna is more ditzy and less 'sane' than others, giving a new flavor but in the same time, detracting those who liked Mitsuki.
Supposedly her actress switched to a different talent agency that's not allied with Toei, not knowing about Season 2, which resulted in Luna being cast. Luna could also be viewed as a parody of idols who've had Sentai roles which have helped their career (such as Shinken Yellow or Mele's actresses).
Turns out Mitsuki's replacement was due to her starring in a movie and scheduling conflicts meant they weren't able to get her to reprise her role. Note the reshoot in Episode 1 of Akibaranger S2 - Mitsuki has long hair in that shot instead of short hair in the original, because Kyoko Hinami had grown out her hair for her movie role.
Take That: More vocal fans who prefer Super Sentai view the Powerful Rangers episode as a proper retaliation to over two decades of Macekre.
While some Power Rangers fans see it as a Take That to the more vocal sentai fans, since it was an alternate reality where sentai actually ripped off power rangers.
Squick: The Season 2 mooks. Would you want people with half male, half female faces with no sense of personal space around you?
Tear Jerker: The revelation about Yumeria's mother near the end of #5, namely the fact that she had been dead for five years prior to the series' beginning, and the scene with Yumeria and her mother was Yumeria celebrating her birthday "with my mother in my mind". Considering that this series is mostly a comedy series, it sort of comes out of left field.
Mitsuki's farewell in the 1st episode of Season 2, with everyone waving good bye for her and wishing her well. The tone got kind of more somber than usual.
The very end of Season 2, which reveals that Nobuo, Luna, and Yumeria really did die at the end of episode 12 and were allowed to return as spirits for the recap. At the end, the first Yellow Four, Time Fire, and Abare Killer arrive to tell them it's time to go, with Hiroyo and Kozkoz, not knowing they're there, nearly crying at their mini-shrine General Pain created before they force themselves to cheer up.
Tough Act to Follow: Season 2 isn't as beloved as its predecessor, as several fans believed that season 1 stood well enough on its own and continuing the series made it stale.
What an Idiot: Oh, Saburo Hatte. Your nurse looks just like a character you created and even has the same name, and you trust her? Even when she knows who you are and tried to defy you?
Hakase... why did you trigger those suicide flags...
