Well, remember when the voice of the toa cd said that makuta made them lose abilities. I have a couple of thereies. He stole there memory(TAKUA!). He made them downgrade(therory). He made there masks not work(GO TO THIS LINK TO SEE A SIMALAR DEBATE. HERE'S THE LINK!!!) And he split them into 6 villages. I hope this topic gets on the hot list.

this may be true you know.

I think this is why there masks do not work.
Good theory. Maybe it will be a hot topic.

I think that the matoran CHOOSE not to use their mask AS MUCH as the toa. Remember( Flashback ) .........oh, sorry. Matoro used his mask to identify Kopaka threw the blizzard.
