On Biosector, I read that the technology that produced the Shadowed One’s species evolved over time, how does that work exactly? I know that new Matoran come into being via special machines, but how does their elemental alignment factor into that? How do other species in the MU reproduce, the Makuta make the Rahi species, but what about the other sentient ones, like the Vortixx, Skakdi and the Barraki’s races?
There is no biological reproduction in the MU. It is all done via machine. As far as how tech evolving works, well, tech always evolves. What works in theory doesn’t always work as well in practice and has to be improved upon.
