And here's the shadow keshuon personally this one and the earth keshuon came out the best.
The tentacle-like things are made from shadows so they can grow back to whatever size. There is a superstition that they are the herald of a horrible event so people believe that it is bad luck to see one. The elbow things are used to catalyze energy into the arms and claws but these can also shoot blasts of energy from the tips. A common misconception among the scholars of the world is that a shadow keshuon refers to shadows. That, however, is untrue. Shadow refers to dark based magic. There are also those who believe that these keshuons are evil. They are also very wrong since it is darkness as opposed to sunlight not the side of light.
It can use shadow based magic.
Like the light keshuon it can walk on darkness and shadow and can move at about 40 mph and can boost that to about 500 mph.
It makes its home in a dimension bubble that it forms in its mind. This bubble is detached from everywhere but the exact area where it made the bubble and entered into it.
Shadow keshuons are among the most intelligent creatures on the world and the most mentally aware (that is how they form the dimension buuble.) They are likely to just sit in their home and ponder something that occured to them. They do not put up with violence and will go out of their way to stop it.
A special ability that shadow keshuons have is the ability to see a person's fears. They use this ability when someone tries to attack them then use their tentacles to shape that person's fear.
The coloring on their bodies is that their body is a shiny black, their tentacles are a dark grey, their eye coverings a dark purple, and the symbol is white.

keshuons of all elements belong to me
