->'''Buffy:''' I was just kind of wondering if anyone else thought that Jonathan is... kind of... ''too'' perfect? \\
'''Xander:''' No, he's not! He's just perfect enough! He crushed the bones of TheMaster, he blew up a big snake made out of mayor, [[ArsonMurderAndJaywalking and he coached the U.S. Women's Soccer team to a stunning World Cup victory!]]

Let's say you're reading through your favorite {{fanfiction}} website and one day, you decide to read some stories set in your favorite fandom. New student joins the school, ho hum... wait, did the main villain [[SwiperNoSwiping just step down after one snippy remark]] from her? That's not right... hey, I thought he already had a girlfriend! Wait a second, did the evil miners all turn themselves in to the police after she had a talk with their leader? Who is this character and why is the whole world bending to her will?

Congratulations, you've just met Black Hole Sue.

Her gravity is so great, she draws all the attention and causes other characters (and, often, [[RealityWarper reality itself]]) to bend and contort in order to accommodate her. Characters don't act naturally around her. They instead serve as plot enablers for her, with dialogue that only acts as set-ups for her response. She dominates every scene she is in, with most scenes without her serving only to give the characters a chance to "talk freely" about her. Most people don't oppose her and anybody who does will either realize their fault in doing so or just prove easy to overcome.

The very laws of the universe bend to accommodate her. If there's only [[MillionToOneChance one in a million chance]] she could succeed at something, she'll [[BoringInvincibleHero accomplish it with flying colors.]] If the logical outcome of the story would end in her failure, a DeusExMachina will ensure her victory. Nothing is too implausible for her to accomplish, whether it be going from RagsToRoyalty, [[DidYouJustPunchOutCthulhu killing]] an EldritchAbomination, or bringing about world peace. If she is so inclined, she may do all that before sitting down to a breakfast [[CanonDefilement consisting of the original story.]]

This is fairly blatant author favoritism in effect, with the author using his or her effective position as {{God}} of the story to carry the character through by her hands. In the rare cases when Sue fails, it will usually be a temporary setback that will either prove advantageous in the end or else just serve to hammer in the point of how special the character is. These failures can often involve just as much DeusExMachina as her successes, setting up events in which she logically shouldn't fail.

Because of this, the character just ends up rather boring to witness. Heroes might be [[BoringInvincibleHero naturally predisposed to winning]] and [[JokerImmunity some villains might never seem to be taken care of]], but Black Hole Sue does away with anything resembling logic to prop up the characters. It stops being a story and just becomes more like a fictionalized resume of improbably fantastic deeds.
