Bionicle characters are said to not be robots-they’re living beings with organs, muscles, etc. Throughout the story, Toa, Glatorian, and Matoran were described as getting tired when they exerted a lot of energy. The Toa even had a “heartlight,” which is presumably a counterpart to a human heart.
But what about eating and drinking?
Despite having cybernetic components, the Toa and Matoran still have hearts, muscles, and lungs. Those are all products of living beings that are classified as animals. Unless I’m not mistaken, every species in the Animal kingdom need to eat and drink in order to survive. And, since the Toa, Turaga, and Matoran are frequently said to smile, frown, scowl, grin, and make other facial expressions, they must have mouths.
Of course, with the Bara Magna inhabitants, this is already explained. On Bara Magna, there were a good number of food and water sources that the Agori squabbled over; therefore, we know that that’s what the Agori and Glatorian eat. But what about the Matoran universe? Was there any information given on what the Toa/Matoran/Turaga/Skakdi/Vortixx ate or drank?
