Any kind of dimensional manipulation can be referred to as "Space"
To take an example from American sources, Hiro from Heroes can manipulate the "space-time continuum". The space half of that gives him teleportation abilities.
Also, "Space" can easily be used to describe different gravity based powers, such as black holes.
My favorite "out there" element is Space, since it's so versatile when used right.
It's just the same as Time, if you think about it the right way. By which I mean Gary-Stu level.
*Doesn't understand the term "Gary-Stu"*
But Space can also be a double meaning, like the space in between objects or outer space.
Gary-Stu is the male equivalent of a Mary-Sue.
Mary-Sue and Gary-Stu are fanfiction/fanwork terms for really...horrible characters.
These characters are usually super powerful, are related or have a romantic relationship with one of the canon main characters, are usually super good looking or super badass looking, and often are some kind of author insertion character.
Basically, 99% of all fancharacters.
Ah, thanks. But I usually tend to make personalities and stories for characters that aren't cliche' or I at least try to...even though my first Sonic fancharacter was related with one of the canon characters...
A lot of my fan characters are either subtle references to various other things I like, while at the same time being original personalities.
For example, the navigator of my One Piece fan-crew is named Diego Von Edgewright.
<_< Guess where his name comes from.
