Fon

Pacifier: Red
Element: Storm
Animal: Japanese macaque (Ri-chi/Li-chi)
Special technique: Bakuren-ken (exploding lotus-ken)

* Amano has placed in manga chapter 250 that Fon is the official spelling. This is the pronunciation of the katakana ‘fu-o-n’ that you see above the kanji.

* Chinese and Chinese-speaking fans often use “Feng” (pronounced “fung” as in feng shui) because this is the romanized spelling of the same character in Chinese. This is not wrong, and is acceptable.

* “Fong” is the variation Viz’s translations are using for Crunchyroll. (I used “Fong” prior to the official spelling, since I tend to rhyme ‘feng’ with ‘cheng’, which would be wrong. However to decrease confusion I’m sticking now to the official spelling for this site.)

what we already know:

- Fon was I-pin’s teacher, the one who taught her martial arts, back in Hong Kong.
- Hibari Kyouya bears a more-than-uncanny resemblance to Fon, which makes I-pin get shy around Hibari.
- I-pin currently carries a stuffed doll resembling him.
- The kanji for his name means “wind” or “discipline”, depending on usage. The kanji is one of the two in Hibari’s arm band (“discipline committee”)

Newer information:

- He’s really a martial arts master
- He has been a champion at martial arts tournaments in China for three consecutive years
- He currently owns a street stall selling gyoza (Japanese dumplings)
- Also fights using gyoza-ken
- Pacifist among the seven

From Haru-Haru Interview in volume 31 [thanks to yamachan01 for the translation]:

- Fon confirms that he is related to Hibari, but they are not brothers. He won’t say anything more, though, because Hibari would get angry.
- His favorite food is mapo tofu
- He has such a strong punch that his air punch can indent an eraser!
