Hi guys!
Regarding the problem, that we don't know what the meaning of the name 'Takua' is, I have found that the word 'takua' in thai means lead (metal). I do not know if it could be connected to him. A southernwestern region of Thailand is named Takua Pa, because it had rich ores. (https://en.wikipedia.org/wiki/Takua_Pa_District)
I also found (however it is very far-fetched) that when lead is burnt (fire=ta matoran) in the flame test, it colors the flame pale blue. Takua's mask was pale blue, but I don' t know if he was originally going to have that color. (https://en.wikipedia.org/wiki/Lead)
