Characters who are capable of significantly affecting
[1], creating and/or destroying an area of space that is qualitatively larger than an infinitely-sized 3-dimensional space. Common fictional examples of spaces representing such sizes are
space-time continuums (the entire past, present and future of 3-dimensional space) of a universal scale. However, it can be more generally fulfilled by any 4-dimensional space that is either:
A) Equivalent to a
large extra dimensional space. That is, a higher-dimensional "bulk" space which embeds lower-dimensional ones (Such as our universe) as subsets of itself, whose dimensions are not
microscopic / compactified.
B) Portrayed as completely transcending lower-dimensional objects and spaces in the setting of a given work of fiction.
