''Warning: Spoilers on this page are unmarked like the other Dangan Ronpa 2 pages''
* ActorAllusion:
** Peko is voiced by Creator/KotonoMitsuishi, AKA Anime/SailorMoon. When she masquerades as Sparkling Justice, 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, Hajime 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 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 Hajime and Izuru Kamukura, doesn't it?
** Another English dub example: A pink haired girl with [[CurtainsMatchTheWindows matching pink eyes]] who sacrifices herself in the name of hope for her friends, but did not really die so much as she is nonexistent in the real world. [[Anime/PuellaMagiMadokaMagica Madoka Kaname]]... or [[Creator/ChristineMarieCabanos Chiaki Nanami]]?
** A third English dub example (and a two-for-one deal, too): A boy is trapped in a virtual world gone horribly wrong. [[LightNovel/SwordArtOnline Kirito]]... or [[Creator/BrycePapenbrook Nagito Komaeda]]? Later, a boy specifically enters the virtual world to save those trapped in it. Again, Kirito... or Makoto Naegi?
** The Logic Dive minigame was [[http://www.animenewsnetwork.com/feature/2015-07-22/interview-danganronpa-creator-kazutaka-kodaka/.90760 reportedly]] inspired by Hinata's actress Creator/MinamiTakayama, and her most famous character Manga/DetectiveConan. Specifically, the Turbo Skateboard he rides around on.
* ActingForTwo: Nagito's voice actors in both the [[Creator/MegumiOgata Japanese]] and [[Creator/BrycePapenbrook English]] versions also voiced Makoto from the previous game. It falls into this trope when Makoto shows up. There's also Creator/AkiraIshida and Jason Wishnov, who both voiced Byakuya in the previous game and again here. It falls into this trope considering that the Byakuya we meet here is an impostor, and the real one shows up later.
* CastingGag: In the English dub. BrycePapenbrook playing a constantly-cheerful yet simultaneously entirely unnerving white haired boy? [[VideoGame/FireEmblemAwakening Now where have I seen that before?]]
** There's also the additional gag of the voice actor for Makoto and Nagito being the same in both languages.
* CrossDressingVoices: Hajime, Nagito and Izuru in the Japanese dub.
* FanNickname: Byakuya 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 someone completely different from the actual Byakuya. In this vein "Fauxgami" is also a common name English speakers use when spoilers aren't considered an issue. In Japan, "Tongami" is a very popular nickname for him.
** Monobear can be considered one too since his official name is still Monokuma.
** Due to its status as a WalkingSpoiler, Izuru Kamukura is being affectionately referred to as "Spoiler-kun".

* WhatCouldHaveBeen: several of the characters' concept designs were released with the art book.
** Nagito originally had glasses, and a hoodie with bat ears that eventually became Chiaki's.
** Chiaki greatly resembled Chihiro, the person who made her.
** Fuyuhiko's prototype, of a big, muscular man, eventually became Nekomaru's design proper. Nekomaru's original was much more standard, with no crazy muscles.
** Teruteru 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 Nekomaru's early designs was a LongHairedPrettyBoy. Another was done in the more cartoonish style that was ultimately used for Teruteru, depicting him as a rail-thin teenager with a shaved bald head, oval eyes and buck teeth.
** Hiyoko was one of the survivors while Fuyuhiko was the victim of the third chapter in the beta version of the game.
** According to some rumors floating around the Internet, Akane was originally planned to be the main villain. This was due to the [[MeaningfulName symbolism in her and Hajime's names]]. Hajime means "beginning", and Akane's last name, Owari, means "end". But this idea was ultimately scrapped.
** As with the first game, there are several drafts for unused executions.
*** If Hajime had been convicted, he would've been [[http://66.media.tumblr.com/85e551c4a1757518f4913f2b288ae7e4/tumblr_mztn3a5p7P1rp03jbo2_400.jpg printed onto a piece of scratch paper]]. Monokuma would then begin scratching him off with a coin as Hajime is helpless to do anything. Once he's completely scratched off, the words "Try Again" are revealed and a disappointed Monokuma litters the paper on the ground.
*** If Nagito had been a culprit, he would've been placed on a wooden platform suspended by several ropes. Monokuma would've then cut the ropes one by one, only to discover they weren't connected to anything, presumably thanks to Nagito's [[BornLucky luck]]. Frustrated, Monokuma would've then set fire to the platform, [[http://65.media.tumblr.com/0fdb34ee7be6549ad01970c789733c03/tumblr_mztn3a5p7P1rp03jbo4_1280.jpg leaving Nagito to burn to death.]]
*** If Fuyuhiko had been a culprit, he would've been placed in the midst of a gang battle. Among the crowd would be someone that looks like Peko and a Yakuza-style Monokuma making its way toward her. Fuyuhiko would've seen this and rushed forward to cover her, only to be fatally shot. The shadow would've turned around to and revealed to be just another Monokuma, [[http://67.media.tumblr.com/0ef3b0b80667e7d0560176a07aca09ae/tumblr_mztn3a5p7P1rp03jbo5_1280.jpg leaving Fuyuhiko with a regretful smile as he dies]].
*** If Kazuichi had been a culprit, [[http://67.media.tumblr.com/1c4bcb5d9240f06b0033394f028fd02f/tumblr_mztn3a5p7P1rp03jbo7_1280.jpg he would've been forced into a drilling machine]], which begins tunneling down toward the Earth's mantle. The heat would've caused him and the machine to melt.
*** If Mahiru had been a culprit, she would've been left in a deserted ruin. There, she would have found a photo album with her name on it. As she begins flipping through it, the pictures show [[http://67.media.tumblr.com/fc6de60de31ac003ca07edfd58bdbc60/tumblr_mztn3a5p7P1rp03jbo3_400.jpg a white hand clamping down on her neck and strangling her]], with the final page showing her lying on the floor. A camera then begins snapping pictures as the white hand appears behind her without her noticing.
*** If Sonia had been a culprit, she would've been made into a snow white puppet by Monokuma and [[http://67.media.tumblr.com/7108fef952c9c7acfd8e89cb245f8e07/tumblr_mztn3a5p7P1rp03jbo6_400.jpg forced to eat a poisoned apple.]]
** Gundham and Chiaki also had alternate executions.
*** Gundham would've been placed inside a giant hamster wheel being chased by a giant Monokuma ball. He would've then tripped, causing his hamsters to fall out. [[HeroicSacrifice He would've rushed to protect them from being crushed]] and [[http://66.media.tumblr.com/5bdfe5dfa16d424fec2a71e1a007b42b/tumblr_mztn3a5p7P1rp03jbo8_1280.jpg died with a satisfied smile]].
*** Chiaki would've been placed on [[http://67.media.tumblr.com/8e5b3f714fd5e6ea912909dfd2140df6/tumblr_mztn3a5p7P1rp03jbo9_250.jpg a giant Sugoroku board]] and forced to move a number of steps determined by dice rolls. She would've managed to avoid a dangerous tile, but then Monokuma would have changed ''all the tiles'' to death tiles. With no other choice, she would've taken a step forward and been electrocuted.
