Okay, so I want to clear up something that's been confusing me for a while.
When Toa Krakua "came out" in 2005, i.e. was shown for the first time and simultaneously canonized, he was obviously wearing a Kanohi Hau (and generally resembled a cyberpunk Tahu but that's another story). At the time, that was explained away as him having a "Hau-shaped Kanohi Suletu" and I believe the Kanohi Suletu was in fact introduced with Toa Krakua (was that LEGO's idea, btw, or was it all John Dexter's head canon made real canon?).
After the Toa Inika came out in 2006 and we were shown that Toa Kongu wears a Kanohi Suletu, albeit organic, Toa Krakua was almost immediately retconned to wear a regular (non-organic) Kanohi Suletu and not a Hau-shaped one.
So up until maybe a year ago, I was under the impression that the latter statement was considered canon, until I started finding conflicting information and at a certain point I even thought Toa Krakua's mask was re-retconned to a Hau-shaped Suletu once again.
So... which is it, in the end?
Thanks. :)
