JackieChan is a well respected, semi-active commenter who plays the role of Uncle Chan from the animated series Jackie Chan Adventures. As such, many of his comments are often punctuated by an "Aiya!", in spirit of the character.
On September 1, 2017, Explosm moderators, in response to a wave of spambots, dished out a wave of bans. Unfortunately, some legitimate users were caught up in the storm as well, including JackieChan. He was unbanned shortly after, but as a result of this mistake, lost his profile picture. As a result, for a short period after, he held the default Explosm avatar.
On November 4, 2017, he adopted the Halloween themed avatar of another commenter, Mrfrogman99, and has been using it since.
