Avatar Fanon Wiki was created on 20 November 2007 by Paperclipchains. The project found it difficult to start, and September 2008 was the first month where the number of active users exceeded six. The only administrative appointment in those months was Masterhybrid. However, the project sustained a level of growth from then, and four administrators were appointed, including Vagrant Lustoid.

On June 27, 2009, Avatar fanon and Avatar Wiki merged into one wiki in order to increase the amount of traffic of future users, creating the Fanon Portal on this wiki. Fanon administrators were created as a result of this merge. The group was later disbanded as a result of community consensus in February 2012.
