FACTS ABOUT NOBODIES
Uhh will make this nicer later I am simply copy/pasting for now.
1) Nobodies do not get sick.
2) They have blood, but it is stagnant.
3) Food isn't necessary, but they're capable of (and enjoy) eating anyway.
4) Some sleep is necessary to replenish, but they don't need as much of it.
5) If Xion is ever dropped/on hiatus/NOT THERE FOR A LONG AMOUNT OF TIME, everyone forgets she exists.
6) Xigbar was taken from Luceti, and therefore has wings.
7) NOBODIES CAN'T FEEL REALLY GUYS. we're mostly sure. IT'S A SENSITIVE SUBJECT.
8) Nothingness feels like shit. Cold and horrible. There's a reason they're all so desperate to regain their hearts, and it's because the lack of one is a very, very terrible thing.
9) The Organization coats are used as protection from darkness. Prolonged exposure to darkness is dangerous.
10) A Nobody is half of a person. Technically, they might be considered two thirds, as they are the body and soul, but as the heart is apparently the most important part, we just say "half."
11) The Organization owned a moogle.
12) They are able to use Corridors of Darkness as portals to pretty much everywhere they would like to go. However, their coats must be worn while doing so.
13) Mickey is a married mouse who has to reject Riku's advances nicely
14) The Coats were woven out of darkness. Probably out of dead heartless skins.
15) They can "speak" darkness (as seen in the prologue to Kingdom Hearts II, when the Dusks speak to Roxas, calling him their liege). Because it is not a spoken language, however, and relies on transmission through darkness, it is untranslatable by the babel fish (mod approved!)
16) Their spoken language, however, is a mix of Disney and Squeenix. That is to say, it is almost universally understandable, providing you are HERO, HEROINE, LOVE INTEREST, COMIC RELIEF CHARACTER, MENTOR/PARENT FIGURE (and let's hope you're not a mentor/parent figure, because in Disneyland all mentor/parent figures die), VILLAIN, VILLAIN'S HELPER, OR ANY ANIMAL EXCEPT A GORILLA. It also sounds a bit like singing.
17) If a person has a weak heart, when they lose it they will become a Heartless: an instinctive monster constantly searching for hearts to steal. If they have a strong heart (whether good or evil) they will create both a heartless and a Nobody: a more intelligent creature capable of strategizing. Only people with extremely strong hearts retain a human shape when they lose their hearts; they became the Organization XIII + Naminé.
18) A member of Organization can be turned into a Dusk (the lowest form of Nobody), however. This is done by stealing away their memories, which Xemnas (his power being Nothingness) can do.
19) Dusks don't have free will. They act more on instinct, although they're still capable of planning. They are very bad at differentiating between different forms of a thing, however. (See: unable to tell the difference between Roxas and photos of Roxas).
20) As a result of their stagnant blood, their body temperature is lower than normal people's. The only exception is Axel, whose element is fire.
21) They do age.
22) Their hair and nails do grow.
23) Xigbar can cheat gravity and raise his own penis.
24) Theoretically, Nobodies can totally hack computers by cheating. This is never fully explained, but they are capable of portaling into virtual worlds. This might include video games or television shows.
25) All Nobodies like Nomura Fried Chicken.
26) Nobodies are very good at going unnoticed. This has to do with the fact that they do not, theoretically exist, and that it's difficult to notice something that doesn't exist.
27) They're capable of having sex. Not that most of them would, but LOOK THEIR NOT-LIVES SUCK, THEY DESERVE THAT MUCH OKAY.
28) The bathroom in the World that Never Was is called Excrement's Loss
29) Xion pees in potted plants.
30) A swirly is why Roxas's hair is like that.
31) That is the real reason Roxas is blond.
32)
Roxas doesn't much like toilets.33) Axel pees fire.
34) Zexion pees out of his pooper.
35) They were immediately able to use their powers, but it took a while to figure out how to control it properly. That being said, it was also intuitive; their power.
36) Replicas (such as Xion or the Riku Replica) are not like Nobodies. They exist even less, for one, and were created using memories.
37) Nobodies cannot create other nobodies via sex IT DOES NOT WORK THAT WAY
