Cubicles

Cubicles are creatures come from another dimension, simply referred to as the Cube Dimension. Cubicles are made of a large amount of individual cubes, kinda like voxels or lego, which is where their name originates from. It is not to be confused for the cubicles in an office. Regular cubicles are typically colossal in size, barely any of them being smaller than a four storey house. A big one can send so called lackeys, which are always small, but never come on their own, and only act on the larger one’s command. Before a cubicle appears a portal is first seen. It’s hard to miss when you see it given its shape and the glow. The portals can actually be very small, and it’s assumed that cubicles don’t go through it in one piece, but rather come in small parts like a lego set, and then construct their bodies once they crossed the interdimensional door. When a cubicle crosses over it can be measured due to the high amounts of energy being released.

Abilities
Cubicles are incredibly fast for their size, and have extremely good reflexes. Regular weapons barely harm them, and they can simply throw away broken cubes, though this takes a toll on their size and strength. It would require a very powerful weapon to destroy a decent amount of cubes. However, cubicles can harm each other rather easily, which is why people develop weapons that take energy from cubes to fight the cubicles. Given that cuboids naturally can pull energy from cubes, their attacks can also harm cubicles. Their regeneration is also impressive, and given their size, cubicles are also capable of lifting large things easily.

Society
It is noted that cubicles possess a kind of hierarchy, and that everyone fits into a certain spot in their society. Those that fall outside are called broken toys. They do not like humans nor cuboids, as those are seen to be ‘conspiring with humans’. Why exactly they dislike people is unknown.

Cube Dimension
Their world is assumed to also be made of cubes, but there are also parts that don’t look much different from the human dimension.
