->''"It seemed a little far-fetched, but Harry is pretty honest and that thing is very tall."''
-->-- '''Hugo''', ''X Mandelbrot''

Yet another Website/YouTube series based on Franchise/TheSlendermanMythos.

Hugo, an OrdinaryHighSchoolStudent is investigating the disappearance of his twin brother, Harry, with the help of his friend, Travis. Before his disappearance, the very GenreSavvy Harry was attempting to write a song about our resident [[Franchise/TheSlendermanMythos thin gentleman]] before he started getting stalked. Harry documented his experience through heavily encrypted video diary entries. Hugo and Travis are now attempting piece everything together.

The series has a [[https://www.youtube.com/user/XMandelbrot YouTube channel]] and a [[http://www.facebook.com/pages/X-Mandelbrot/254218587942656?sk=wall Facebook page]].

!!"X Mandelbrot" provides example of:

* BreatherEpisode: The seventh video is entitled "(attempted) Breather Episode."
* CrazyPrepared: Harry somehow managed to [[spoiler: get a Colt Python to defend himself]].
* CrossOver: It seems Hugo may be trying to start one, judging by a comment he left on an WebVideo/EverymanHYBRID video.
* DeadpanSnarker: Harry's reaction to the disturbing videos he was Emailed?
--> "You probably think you did a good job scaring me with those videos. That's cute."
* FanService: Harry frequently doesn't wear a shirt in his videos. Justified though, as it's often night time, and some people don't wear shirts to bed.
** Later lampshaded by Hugo who in "Sleep Recording", said:
--> "I've heard people talking about how Harry never wears a shirt in these videos. You're lucky he's even wearing pants here!"
* GenreSavvy: Harry is (was) very aware of being in a situation much like that of WebVideo/EverymanHYBRID and even mentions them by name. His song is what seemed to get Slendy's attention.
* OrdinaryHighSchoolStudent: All of the characters were this. Until Slender Man got involved.
* PoliceAreUseless: Said almost word for word by Hugo in "Maine".
* LastNoteNightmare: "Harry's Tapes Part 2" ends with some highly distorted coughing.
* ShoutOut: Mostly provided by Harry, who mentions ''Series/DoctorWho'' and says "Fezzes are cool." as well as various Slender Man Vlogs.
* WhamEpisode: "Judgement", Hugo and Travis explore a place Harry visited, [[spoiler: they are soon being shot at by some unknown attacker]]. When they return to Travis's family's camp, [[spoiler: Slenderman is waiting for them]]. Hugo then explains that him and Travis no longer have any doubt that this is indeed Slenderman they are dealing with.
