Yeah, Figured.
I the science stuff I was mainly wondering for things like Voriki using lightning to create a electrolysis in the water. Lewa controlling the resulting air, to extend their ability to be submerged under water. Also, it was to determine, although I think I forgot to ask, if Matoran, Toa and rahi require oxygen as their main metabolic catalyst. So if they need to breath oxygen or if they use another gas. Otherwise the electrolysis idea will not work. Also, if they can only survive at specific temperatures or envirmental conditions like us humans. Another question I forgot to ask is how advanced is their understanding on their needs and such. Do they know they need specific gas to breath? or they just know they require air. Do they know they can only survive at specific temperatures, how long they can survive without eating? drinking? Do they have organs that are fundamental for their bodies to function?
Can they survive with a whole through the chest? Do they replace damaged parts? or they they heal their injuries? Can they replace things like heads? Torsos? Arms? Legs? This is also important if you want to make war injuries important and meaningful. Matoran who went to war and lost limbs. Also, the answer to these questions set the bar on how important things are, fighting styles, and so on. If you want to defend what do you protect, where do you aim and when do you aim for such places.
I am sorry, I ended asking other questions. I was recently thinking on fighting styles and how each region fights. If they use types of martial arts and how do each develop. So these question are coming as a result of that.
