Habitual behavior
Supreme Genghis Khan's disruptive behavior takes many forms, the most common of which include the addition of duplicated images to articles and other users' userpages, and other image vandalism such as the replacement of images in BLPs with an image of Genghis Khan, Osama bin Laden, or North Korean leadership (Kim Jong-un and Kim Jong-il; ). Edit summaries can be obscene or defamatory (e.g. "F*** you, [user]!" and "[User] has AIDS!"; ) and may have to be hidden by administrators. This image vandalism can cause browsers to crash; some instances have added nearly 2,000,000 bytes to a page (example).

Other disruption patterns include replacing article content with giant text (e.g. "GENGHIS KHAN FAVOURITE...!"; ), full unwikifying of articles by adding tags, personal attacks (often gross; e.g. "[User] is a rapist/pedophile/sex offender") and harassment, abuse of warning templates , vandalistic and malicious page moves , impersonation of other users through usernames and signature forgery , creation of hoaxes and attack pages, blanking of AIV reports and obscene unblock requests.

Supreme Genghis Khan has a history of adopting usernames which impersonate or attack users who have blocked or reported him, making close typos, adding e.g. "Genghis Khan", direct attacks, or in some cases variations of the Khan moniker using accented characters to evade detection. Several editors (such as ) have been targeted in this way. Some of his usernames use French language words (example), as evidenced by a recent sockpuppet investigation.

Starting in 2023, this user has also engaged in racist vandalism, typically involving racial stereotypes related to fried chicken and watermelons. Also, there seems to be an ongoing pattern of Genghis Khan related vandalism to MongoDB.
