as one of the older farts around here, i can remember the day when me and my old pals went hiking down the- oh sorry wrong flashback. yes there was the old Nickelodeon website that stated Hakoda travelled to the other tribes to find a teacher for Katara.
the southern raiders not knowing about Katara but knowing about 'a waterbender' is cartoon canon. why? probably because fire navy captains can't hear good intel over the sound of how awesome they think they are. standard Fire Nation incompetence.
Hama's flashbacks were from when the firenation war first came to SWT mainland. all the men were out at sea fighting the war there, leaving Hama and the other women to defend the -back then, still standing- homes. (given that both men and women ended up fighting, and how successful the women actually were, i don't know why the forces were split gender-wise. guess sexism isn't that much of a northern exclusive thing?)
it's only after the women lost and Hama was taken, that the villages were destroyed/reduced to tents and freezing outhouses.
well, whaddayaknow. the old website was rescued! it's right here
it's a bit hard to navigate but with the help of the Appearences list on Hakoda's Wiki page
i managed to find his character profile under episode 219.
hmm. curious though.
both the wiki and the old avatar portal almost never speak of the Southern Water Tribe in plural. it's always just "Tribe".
only the wiki mentioned Hakoda being
the chieftain of a minor tribe at the South Pole that was part of the Southern Water Tribe's tribal confederation. Even though Hakoda was not the formal chief of the Southern Water Tribe, he was one of its most prominent leaders at the end of the Hundred Year War
but references The Lost Scrolls: Water
for that bit.
i guess everyone from the South Pole is SWT, but the specific "sub-"tribe is never mentioned. though jokingly, Sokka was greeted as "Sokka Watertribe" so i guess it's as specific as it needs to be. Hakoda would have had to meet and identify himself to someone from the WST but from another village for us to find out.
