- Bland-Name Product examples like the Nastea, Cylon Tea (comes in 12 flavours), the Bauer Bar (gives you 24 hours of energy!) and tidbits like Apathy Syndrome being postulated to be the curse of the local shrine god, along with many, many others. The game's brimming with shout outs to just about everything.
- In the Japanese version, the takoyaki stand is named "Octopussy".
- The way the Personas are evoked are quite similar to how Jotaro Kujo calls out his stand for the first time.
- Not too many people think to combine teen angst, philosophy, psychology and religious symbolism, but nowhere is the influence of a certain massively popular anime more obvious than in the awakening of the main character's Persona (compare with this battle (2007 style) in aforementioned anime).
- Junpei: I pity the foo' who don't know when to quit! Mr. J says to throw in the towel, boy!"
- "I bet he'd slit his mama's throat for a five-yen piece!"
- One of the weapons you can find for Aigis is the Six Shot. It can transform into six different shapes.
- For those who don't quite get that reference, Six-Shot is a Decepticon with six different forms.
- Speaking of weapons, one of Junpei's earlygame weapons in Persona 3 Portable is the Great Sword, which happens to be a hiltless, thick, raw mass of iron taller than the wielder. If that description doesn't strike you uncanny, here's a hint: it looks just like the Dragonslayer.
- Unrelated, but some Fridge Logic: if it's really a reference to the Dragonslayer, how in Nyx's name is Junpei swinging around what is effectively a 400-pound replica of the Dragonslayer, let alone carrying it?
- Continuing with the weapons, the Female Protagonist's Beam Naginata gives off a very familiar sound when swung.
- Two of the movie posters in Portable are Detonator and Friday On A Certain Day.
- Junpei's Believe it or Don't?
- Aigis's gun Phalanx B2 is clearly based on Samus Aran's Arm Cannon, specifically in missile mode (and it seems to fire missiles to boot).
- Nata Taishi's design is clearly based on Astro Boy.
- The Persona Hell Biker. Its Japanese name is Hell's Angel, which makes it a double Shout-Out.
- The Very Top of tartarus where Nyx Avatar is fought highly resembles the top of Temen Ni Gru from Devil May Cry 3.
- During one of the student conversations that you overheard before an exam, a student shouted "Sine! Cosine! Tangent!" note , to which the other student promptly replied with "Megido! Megidola! Megidolaon!"
- Those Featherman episode names every week? Look at the number and name of the episode, go to the Wikipedia page for Choujin Sentai Jetman, and go to the episode list. Every episode of the show corresponds to the Jetman episode of the same number. All of them. And, yes, Jetman is one of the main shows Featherman is an homage of.
