Gotham Girls is one of the few series of Flash animations made by a professional publisher of mainstream cartoons, and features professional voice-acting by the same actresses and actors as those who voiced the television series. Its use of Flash enables the animation to appear undistorted and unpixellated at any resolution. However, the episodes do not tend to show the Symbols outside of the intended viewing area. For example, in Season 1 Episode 1 while the light beam on Harley continues off screen, her body is only drawn for the dimensions of the intended viewing area. Each episode features a mini-game or puzzle which can be played while the clip downloads, as well as an interactive feature which allows viewers to help a character make a certain decision. Other features of the website include downloadable trailers, screensavers, desktop backgrounds, internet chatbuddy icons, as well as biographies of the characters, and an online version of the classic game Othello featuring the Gotham Girls. The screensavers, desktop backgrounds and internet chat buddy icon sites, however, no longer work, and simply redirect to the Warner Bros. website, as the Gotham Girls website also does. The series lasted for three seasons, with each episode released month-by-month. While the first two seasons featured primarily comedic episodes, the third season attempted to make the show more serious. These episodes linked directly to '. Dropping the magician Zatanna from its lineup and adding a host of new characters to the cast, including Detective Renee Montoya, each episode from this series tied into the next, forming a collective thirty-minute whodunit. The storyline also dealt with issues not seen since ', such as the corruption of the Gotham City Police Department, Poison Ivy's environmental crusade and Commissioner Gordon's wavering faith in costumed superheroes. It is also heavily implied that the series takes place in the DC animated universe. One significant aspect of the third season is the appearance of Det. Selma Reesedale, a character revealed early on to be a transgender woman. The series finale, "Cold Hands, Cold Heart" aired in 2002, wrapping up the mystery and ending the website. The final episode was dedicated to the memory of Hilary J. Bader, script writer for numerous DC Animated series, and who had died in 2002 of cancer. GothamGirls.com is no longer online, but the individual.swf files were still accessible until mid-2015.
