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...
