Variant:Unknown is a tag on the Soy Booru used to describe jaks that can't be tagged as any of the existing variants. Variant:Unknowns that attempt to pass off as new variants are commonly described as coal or brimstone. Occasionally, Variant:Unknowns are described as gems, but there are exceptionally few Variant:Unknowns that take off and reach known status. On a few occasions, a particular depiction of a variant:unknown (such as the one janny paycheck ‘jak that you WILL find on your own) might become somewhat popular about soyteens though. Sometimes, an existing variant is deformed beyond recognition, and that instance becomes a Variant:Unknown.
Variant:Unknowns tend to be tracejaks, and miss typical visual cues of a Soyjak. This is one of the reasons they are NAS coal. Popular jaks are almost always better than Variant:Unknowns, and easier to find. The main exception is when ARYANS force a name onto their poorly drawn coal nobody uses, and spam hundreds of low effort flag edits of it.
THIS IS ALL THAT IS KNOWN ABOUT VARIANT:UNKNOWN YOU WILL NOT INVESTIGATE FURTHER
