Dimensionality

1. The state or characteristic of possessing dimensions.
2. (*chiefly mathematics and computing*) The number of dimensions something has.

https://en.wiktionary.org/wiki/dimensionality

**Dimensionality** is the n number of degree of freedoms or directions of a character. For example, Humans are three-dimensional, since Humans degree of freedoms or directions extend to three axes that are perpendicular each other: x, y, z. Common Humans degree of freedoms or directions are: left and right; forward(s) and backward(s); up and down.

## **Dimensional Tiering**

### **Common spatial dimensions**

#### Zero-dimensional (0D)

Characters devoid of any degree of freedom or direction, because they do not move in respect to any axis.

**Note**: Characters listed as **Zero-dimensional (0D)** do not mean that they are "**transcendental**" or transcend the concept of dimension. They are rather "**dimensionless**" due of their lack of extent in space. The reason why it is nonetheless in the category of dimension is because the first-dimension, a line, is an extension of zero-dimension, represented as a point.

#### One-dimensional (1D)

Characters with one degree of freedom or direction. Such characters move anywhere in respect to a single-axis or line: x.

#### Two-dimensional (2D)

Characters with two degree of freedoms or directions. Such characters move anywhere in respect to two perpendicular axes: x, y.

#### Three-dimensional (3D)

Characters with three degree of freedoms or directions. Such characters move anywhere in respect to three perpendicular axes: x, y, z.

### **Temporal dimension**

#### Time (4D)

In fiction, time is commonly regarded as "the fourth dimension" part of the spacetime continuum (i.e three dimensions of space and one dimension of time). Therefore, for this reason, time is the dimensionality for **4D** characters.

Time is also commonly regarded as a geometrical dimension: a one temporal line in direction to the future, as portrayed in the picture above.

### **Higher-dimensional**

#### Extra-dimensional

Characters beyond the four dimensional spacetime continuum. In fiction, such characters are usually shown being qualitatively above other dimensional characters existing in dimensions below them. The most notable example is the fifth dimensional imp Mxyzptlk from DC Comics.

Therefore, only characters shown being qualitatively above other dimensional characters existing in four dimensional spacetime continuum universe(s) can be categorized as **Extra-dimensional.** This therefore means that **characters drawing their power from extra-dimensional sources are not categorized in this tier**, since they do not match the criterion based on being "qualitatively above", as their power is explained by the fact that they use extra-dimensional sources giving them extra-dimensional powers, such as the ability to travel through the dimensions of spacetime.

The dimensionality for extra-dimensional characters range from **5D** to **Infinite-D**.

#### Trans-dimensional

Characters who either transcend the concept of dimension or transcend the concepts of space and time. Such characters are qualitatively above any n dimensional characters and are obviously unaffected to anything in relation to space and time.

The level/plane of existence in which they exist can obviously not be reached by means in relation to space and time, e.g breaking down the barriers of spacetime, teleportation, wormholes, etc. contradicting their trans-dimensionality. They are also unaffected by the destruction of the physical universe, realm, world, etc. as their level/plane of existence is rather meta-physical. So characters such as the New Gods can, however, be categorized in this tier because **their existence expresses an idea** (in the case of the New Gods, our contemporary society in Manichean view).

Therefore, trans-dimensional characters are the most powerful in their verse. Of course, not taking into account **Boundless** characters.
