[[MostWritersAreMale One of the few well known female comic book writers in existence]]. Simone has written multiple books, mostly for Creator/DCComics (including ''ComicBook/BirdsOfPrey'', ''[[ComicBook/TheAtom The All-New Atom]]'', and ''Franchise/WonderWoman''), though she also had a famous run on [[Creator/MarvelComics Marvel's]] {{SelfDemonstrating/Deadpool}}. She is the one charged with coining the infamous phrase 'women in refrigerators', and has an entire [[Website/WomenInRefrigerators website]] dedicated to such instances.

Gail is known for being unfailingly polite and friendly to her fellow creators (going as far as to say ''ComicBook/AmazonsAttack'' has good points and defending the artwork of Creator/RobLiefeld when they did a ''ComicBook/TeenTitans'' arc together), and interacting a lot with the Internet fandom. She visits and debates with members of scans_daily, has founded the Wonder Woman section on the CBR boards and hangs around Comic Bloc as well. She used to be found on the [[http://forums.comicbookresources.com/forumdisplay.php?f=34 You'll All Be Sorry!]] forum on Comic Book Resources, named for a satiric column on comics she used to write before working for mainstream comics. She now has her own website at [[http://www.gailsimone.net gailsimone.net]].

In 2010, she finished ''ComicBook/SecretSix'' and concluded a second run on ComicBook/BirdsOfPrey, which she started writing after her years on ''Wonder Woman''. Most recently, she enjoyed a long run on the New 52 ''ComicBook/{{Batgirl| 2011}}'' and a somewhat shorter run co-writing ''[[ComicBook/{{Firestorm}} The Fury of Firestorm]]'' with Ethan Van Sciver. When she was fired from the former (via e-mail, no less) the {{Internet Backdraft}} resulted in her quickly being put back on the book. She is currently working on a new ''ComicBook/SecretSix'' series, ''ComicBook/CleanRoom'' for Vertigo and Leaving Megalopolis Surviving Megalopolis for Dark Horse.

!!Gail embodies these tropes:
* {{Cloudcuckoolander}}: It happens, especially on her Twitter.
* DeadpanSnarker: See most of her comments on the internet, as well as her writing.
* ExactlyWhatItSaysOnTheTin: As she frequenty reminds people, King Shark is a shark.
* FieryRedhead
* GirlsHaveCooties: A regular victim to executives who believe in this trope. [[NeverLiveItDown Her being fired by e-mail from]] ''Batgirl'' stands as the crowning example.
* InsultBackfire: Often responds to people calling her a Feminazi by joking about how much of a Feminazi she is.
* MostWritersAreMale: Initially, she was the ''only'' woman working on the 2011 DC reboot (out of 52 creative teams). The second wave added three more: one writer and two artists.
* TheKnightsWhoSaySquee: To some extent, with Bryan Q Miller: Both are big fans of each other; ''ComicBook/BirdsOfPrey'' was a title Miller was clearly a fan of and followed a lot (including working in plot points of the series into his own) while Miller's writing as what completely flipped Simone's opinion on Stephanie Brown, and now the two are reportedly good friends.
* [[PromotedFanboy Promoted Fangirl]]: Gail started off as a fan of comics who made a site, before getting a job writing Simpsons comics. Then Marvel hired her to write the last storyline for the ''Deadpool'' comic and the opening arc of ''Agent X'', before jumping ship to DC and writing many of their comics. Now she's one of their biggest name writers, and probably the main reason for the current Batgirl series to sell so well despite some critical backlash.
* VitriolicBestBuds: With Dan Slott and Creator/ChuckDixon.
* WhatCouldHaveBeen: Twice she's had a pitch which would have pleased a large number of fans. Firstly, she wanted to bring Cassandra Cain into ''ComicBook/BirdsOfPrey'' with a story that would transform her into a Christian, citing the fact that while an atheist herself she feels religion is misrepresented in comics. Secondly, she pitched a new book for the [[{{ComicBook/New52}} New 52]] which involved Stephanie Brown and a handful of other missing female characters and form a team and would be co-written by Bryan Q Miller. Both were unable to come to pass due to some issues involving both Cass and Steph.
** She had several scripts written that were scrapped when she was briefly fired from Batgirl, and her concept for the "Zero Year" crossover issue of Batgirl was "cool," but [=DC=] wanted someone else to write it. But the crossover isn't editorially mandated-- the writers of the various books all expressed interest!
** DC also rejected a pitch for a Shazam family comic that would be written by her Mark Waid and Grant Morrison.
