I am very well aware of this, that's why I noted it as a probable outlier. Though, Slenderman did canonically stalemate Jeff the Killer and Zalgo and also defeated Ben Drowned and Sonic.EXE in the canon.

Since creepypastas cross over frequently, I do believe that they're the same verse, especially seeing as how only Slenderman turned into a franchise/verse of its own. He's still Creepypasta though. Another factor is that there's a character, Mr. Creepypasta, who IIRC is the God of the Creepypasta Verse.

But again, Slenderman's fight with Zalgo was likely an outlier, that's why I noted that down and also applied a "possiby" rather a definite Low 1-B.
