Miscellanium
Miscellanium, often shortened to "Misc", is a concept of a character defined as having no lore or canonical traits. While Miscellanium's most common depiction is that of a multi-limbed red-furred cat-like creature, Miscellanium is able to be interpreted as having any form, personality, and traits that the artist desires. Multiple interpretations of Miscellanium are also often portrayed together.
Miscellanium 1
Miscellanium 1 is the original design for the character, being a shapeshifting multi-limbed red-furred cat-like creature. Miscellanium 1's head has two spherical tufts on each cheek, with an additional tuft that extends outwards and droops down. The face is adorned with several lighter patches of fur, with there being markings on the ears, at the forehead, below the eyes, at the cheeks, and on the tufts. The arms also have lighter fur which typically spell something. Miscellanium 1's tongue is also forked.
Miscellanium 1 is often portrayed as being an arrogant, selfish person, berating and otherwise being difficult towards others. The dialogue used by Miscellanium 1 is most often put through an unknown alphabet which can be used for any language.
Miscellanium 2
Miscellanium 2, sometimes nicknamed "Categorium", is a smaller monopedal red-furred cat-like creature inspired by that of earlier Flipnote animations. Miscellanium 2 simplifies the design characteristics of Miscellanium 1, with the cheek tufts simply being pointed spikes and complex patterns being dropped.
Miscellanium 2 is often portrayed as being careful and anxious, often hesitant to speak or otherwise do something—usually blamed on Miscellanium 1. Miscellanium 2 is generally more receptive towards others.
Miscellanium 3
Miscellanium 3 has a similar form to Miscellanium 1, but simplifies the shape such that it can be easily drawn with few polygons. Only the general silhouette is retained, as most of the fur patterns are not present at all.
Miscellanium 3 currently is seen as being more positive and enthusiastic compared to Miscellanium 1.
