* ActorAllusion: Peko is voiced by Creator/KotonoMitsuishi, AKA Anime/SailorMoon. [[spoiler:When she masquerades as Kira Kira-chan, she wears a MagicalGirl mask that greatly resembles Sailor Moon and makes a speech about punishing people with justice.]] Since Mitsuishi was one of the voice actors that the script writer specifically asked for, this was most likely done intentionally.
** In the English dub, Hinata is voiced by Creator/JohnnyYongBosch, who voiced [[TheHero Yu Narukami]] in ''VideoGame/{{Persona 4}}''; fitting, since both games revolve around finding the truth. However, he ''also'' voiced [[spoiler: Tohru Adachi, the seemingly-harmless cop who is driven by his envy and misanthropy to try destroying the world. Sounds an awful lot like pre-amnesia Hinata and Kamukura Izuru, doesn't it?]]
* ActingForTwo: Komaeda's voice actors in both the [[Creator/MegumiOgata Japanese]] and [[Creator/BrycePapenbrook English]] versions also voiced Naegi from the previous game. It falls into this trope when [[spoiler:Naegi shows up]]. There's also Creator/AkiraIshida and Jason Wishnov, who both voiced Togami in the previous game and again here. It falls into this trope considering that [[spoiler:the Togami we meet here is an imposter, and the real one shows up later]].
* CrossDressingVoices: Hinata, Komaeda and [[spoiler:Kamukura]] in the Japanese dub.
* FanNickname: Togami as he appears in this game is known by fans as "Fat Togami" or "Fatgami", due to how...[[FatBastard different]] he looks from when we last saw him. "Twogami" and "2gami" are also popular, given how he's [[spoiler:someone completely different from the actual Togami]]. In Japan, "Tongami" is a very popular nickname for him.
** Monobear can be considered one too since his official name is still Monokuma.

* WhatCouldHaveBeen: several of the characters' concept designs were released with the art book.
** Komaeda originally had glasses, and a hoodie with bat ears that eventually became Nanami's.
** Nanami greatly resembled Chihiro, [[spoiler:the person who made her]].
** Kuzuryuu's prototype, of a big, muscular man, eventually became Nidai's design proper. Nidai's original was much more standard, with no crazy muscles.
** Hanamura was a standard tall and slender {{Bishounen}}.
** Mikan had shorter hair and more of a MadScientist vibe, being covered in stitches (in fact, one sketch has her hand falling off at the wrist) while carrying around a BrainInAJar.
** One of Nidai's early designs was a LongHairedPrettyBoy. Another was done in the more cartoonish style that was ultimately used for Hanamura, depicting him as a rail-thin teenager with a shaved bald head, oval eyes and buck teeth.
** Saionji was [[spoiler: one of the survivors while Kuzuryuu was the victim of the third chapter in the beta version of the game.]]
