Like I've said before, I find Black Hole Sue
to the only one that really, really
perfectly describes what a Sue is/does.
A Sue destroys the logic/consistency of the setting simply by existing. Once he/she is placed into the story (whether it's an original work or a fanfic) everything is changed simply because the Sue exists.
It's like the "black hole" concept: gravity affects everything in the universe at the same time. So, once an object exists, no matter how small or insignificant it seems
, it has at least some kind of effect on an object all the way on the other side of the universe.
