Jester

Sen, often referred to as the Jester or Jestermammal before its name was revealed, is a character played by Serpy.

Appearance
A vaguely humanoid creature whose features resemble that of a jester or mime. Their body is black and white, with a variety of asymmetrical stripes and patterns, and their eyes are red with black sclerae. They have a tail, currently too powerful to be beheld by mortal Minecraft clients, and structures on their head that resemble a floppy jester's hat (though it is confirmed it is not a hat).

It has what Serpy describes as "Digimon proportions"— close to human but not quite, with long arms and big hands. Also it wears pants.

Observation Log
The jester is a very mysterious creature, so information about it can only be gleaned through observation. The description below is an incomplete, crowd-sourced collection of findings thus far. Please feel free to add anything you feel is missing.

Abilities

 * Shapeshifting
 * Flight
 * Teleportation
 * Invisibility
 * Manifesting objects and creatures
 * "Uppies" / "Space Cowboy"
 * Possession or "Meat Swap"

Behavior & Personality

 * Claims to not know its own name.
 * Prefers to speak in whispers, as there are things listening. Somehow manages to whisper in all caps.
 * Seems to have a much greater insight on things the rest of us barely begin to understand, judging by its comments. Possibly semi-omniscient?
 * Has indicated knowledge of the future, such as when it foretold the complete temporal annihilation of the Air Bud movie series.

Interactions with others

 * Appears to have a uniquely positive relationship with IMPALE, referring to it as "my friend", providing insight to its feelings, and having fun with it. It is unclear whether IMPALE regards them favorably as well, but notably, she rarely (if ever) targets them for violence.

Quotes (WIP)

 * IT'S 2019!

Trivia

 * Sen is part of an Apex Legends e-sports team called DarkZero Core, alongside Kore, Nebula, and Oracle. Its username is silly of goofiness.
