Suburban Senshi is a fan-created MassiveMultiplayerCrossover centered in the Sailor Moon universe. Started in 2002 by Doctor Xadium, the site centers around a present day versions of the now mostly retired Sailor Senshi, set in a universe where almost any fictional series can exist. The story is told though chat logs between characters, stories written by Xadium, an RP chat room, and stories created by users in said chatroom (Though the chat room and related stories are mostly ExtendedUniverse and not always mentioned in the "chat logs"

-----
!!''Suburban Senshi'' provides examples of:
* AuthorAvatar: Doctor Xadium.
* CrossoverShip: [[SailorMoon Hotaru/Sailor Saturn]] and [[Manga/DeathNote L]]
* EverythingsBetterWithPenguins: The Prinnies dood. The chat room has 3 main groups of Prinnies. The Haz-Mat Prinnies, Shin's Prinnies, and Etna's Prinnies (the only ones canon to their original series)
* FaceHeelTurn: Sailor Moon, Sailor Pluto.
* GenderBender: Haruka/Sailor Uranus, thanks to Sailor Moon.
* HeroOfAnotherStory: Matsuo Shin is a glaring example. Most of the characters are heroes of their own stories, but most of the stories have already happened by the time they show up in canon.
* IdenticalGrandson: Harriet S. Weinberg, Granddaughter of Sagitta Weinberg. (Though this is mostly due to Xadium just using images of Sagaitta to represent Harriet)
* LethalChef: Michiru. Also in the chatbox, Flonne.
* MassiveMultiplayerCrossover
* MyGrandsonMyself: Gemini Sunrise uses this to preform on stage after traveling into to the present, claiming she's the famous Gemini's granddaughter.
* NoodleIncident: A Meta example. The players will often refer to people that have been banned from the site but will refuse to speak of WHY said people were banned to avoid dredging up bad memories and starting arguments.
* OriginalGeneration: Quite a few original universes have been added to the Multiverse by players.
* PlutoIsExpendable: Played straight after Pluto's IAU demotion, causing Setsuna to lose her Senshi powers and turn emo and slightly insane. The chat room even filtered out "Pluto" to it's numerical designation. Once Sailor Moon returned post FaceHeelTurn, she gave Setsuna back her powers and removed the filter.
* RealityWarper: Usagi, Chibi-Usa. In the chatroom, Sailor Neggerra.
* SailorEarth: It's a Sailor Moon based fan-fic. This is to be expected. Quite a large number of object's within our Solar System have been claimed by players already, and a few originals not based on any real planet (Sailor Bandersnatch, Sailor Quinox, Sailor Neggerra for example) pop up as well. Non-Sailor Moon Examples include Doctor Xadium and Thrash, original Time Lords.
* SelfInsert: A few characters are based on their players (And a at least one is a GenderFlipped version). [[TropesAreNotBad Most are written well enough that you wouldn't notice]]
* TheWikiRule: It has it's own wiki, which is useful for keeping track of the current canon status of different elements originating in the various series.
