- Narly actually took this as a dare. Someone asked him "Okay, if you're so smart and powerful, can you actually improve a human's life by their own standards?" trying to use the old Free Will Logic Bomb. Now it can say "Yes, I did it once. I'm very aware of what I'm choosing to do to you."
- Or maybe she's an exceptionally eccentric incarnation of Haruhi...
- Alternately, Guu is the herald of the Spiral Nemesis.
- Jossed, as Guu can't "end" humanity, anything she swallows remains alive.
- You're assuming that this isn't the case because she happens to like it that way, for the moment.
- I mean come on! Same size, same noseless face, same stoic attitude, same ability to make a bitch out of even the most powerful people; not to mention her eyebrows looks like an "M" if you bridge the gap between them.
- Guu? Arrested? What are you smoking?
- That's the part you find unbelievable?
Last, but not least, Guu is the new Avatar(Bet you saw that coming from a mile away). Hale (And Dr Clive, to an extent), are the only ones unaware of this. When Guu first arrived in the village, she told everyone at the village meeting who and what she was and they accepted her with open arms. All the parents told their children of this development and thus almost no one in the village is alarmed at her antics. Weda didn't tell Hale about who Guu was because to do so would make him overly jealous of her and could cause unheard of damage to either his own mental state or Guu's physical one. Besides, Hale has an idealist image of what an Avatar should be like, so when he see's Guu, he thinks monster as opposed to Avatar. One more thing: Since the four elements are now practiced by everyone the Avatar is now charged with (As well as protecting the people and preventing another world war) discovering what other elements or principles can be bent by humans. Most of the crazy stuff that Guu does on the show is either practicing other bending tecniques developed by former Avatars or discovering and applying tecniques she developed herself.
Recall how in the beginning, Guu took on a large, monstrous black shape, suggesting she was some sort of powerful deity, and suggesting that this deity was black. Ravens are also black, but admittedly they are not very large. Recall the episodes in which Guu became an older form of herself to protect Hale and his friends. This may have been the avatar of the creator raven, while Guu's smaller, more childlike self is the childish raven. Recall the episode in which Dama was cutting Gupta's hair and told everyone about their guardian spirits. She freaked out when she got to Hale and didn't see anything for Guu. Perhaps when she identified Hale's guardian spirit she saw a god (the raven) and was at first amazed, and then shook her head in disbelief and proceeded. If that were the case, when she failed to identify Guu's guardian spirit, it could be because spirits have no guardian spirits.
Who knows why the raven took special interest in cultivating and caring for Hale? Perhaps he is the reincarnation of the daughter of the one who guarded the materials from which the raven fashioned the world, the gray eagle. The story says that the raven fell in love with the gray eagle's daughter, and was once a snow-white bird, which the daughter found pleasing. When the raven stole the elements, it carried them in its beak and burned itself badly while trying to carry the element of fire, and it is now black (and presumably regarded as unattractive by the gray eagle's daughter). This could be symbolized by Guu's habit of changing faces and the fact that Hale only likes her when she's wearing her cute face (during which time her other abilities do not appear to manifest, just as the raven could not create the world before it had stolen the elements).
Also in the festival episode, there was a bird shape on the curtains for the play. And in Episode 20, when Guu was wearing the polar bear skin and closed the curtains to prevent Hale from watching her prepare food, a silhouette of a bird flashed. Guu could have needed to briefly revert to her true form for some reason, which was why she didn't want Hale to see. A more likely story is that she was just fooling with his head, as implied more directly, but it could be both.
Clive's story can also be considered homage to the story of the raven. The raven and the gray eagle's daughter were superficially romantically engaged, and when the raven stole the elements from the gray eagle, it turned black, and the gray eagle's daughter no longer took interest in it. Similarly, in Clive's story, Clive and Weda were superficially romantically engaged, and when Clive stole virginity from Weda, Weda no longer took interest in him, and an indeterminate amount of time afterward, he dyed his white hair black. From this perspective, Hale's birth in the jungle could be considered representative of the raven bringing the elements to mankind, represented by the jungle, while the spirit world in which the raven and the gray eagle initially resided could be represented by the city. By this reasoning, Clive's story is arguably a better match for the raven than that of Guu, but Guu's story matches well enough as well that it seems silly to disregard this match, even in favor of a closer match. Perhaps Guu is related to Clive somehow. Perhaps Clive's spirit guardian was the raven, but it was passed on to Hale when he was born, explaining Guu's appearance.
