While that's true, and I agree that on Mata Nui they had to "grow up fast" in that way due to the Rahi, let's keep in mind they spent thousands of years working, and working hard, in Metru Nui. It still doesn't seem much like children to me. More like industrial workers. Unless we want to see it as child labor lol.Also, Lhikan/Vakama would probably look like citizen to hero to us if Vakama wasn't smaller.I know the Matoran wouldn't be completely like OUR children. If that was the case, mo work would be done. But there is defiantly a child like element to them.
