My sister was talking about how annoyed she was about alternate universes in Bionicle, because in alternate universe characters behave very differently and them behaving in those ways is just as 'real' as their standard behaviours. So for instance, Onua is evil in the Toa Empire alternate universe, making Onua just as truly evil as truly good, something that understandably would frustrate someone emotionally engaged with that character.Buuut, I figured out something that resolves that and makes a lot more sense.The usual theories about branch universes is that branches are created in a couple different ways; one, alternate results of random factors (like Schrodinger's cat), and two, alternate decisions made by people.To clean things up a little, I'll go forward with these hypotheses.First, that there's no such thing as the Butterfly Effect, a theory in which tiny factors, such as the movement of a butterfly's wings, can effect gigantic factors, such as a hurricane.Second, that random factors DO NOT create branch universes. So I'm saying that the universe is an entirely predictable entity, that will always act exactly the same way in the exact same set of circumstances.Which leaves only one thing that creates branch universe; important decisions made by the people in them.Back to my original thing. What defines a fictional character, or a real person? What makes them who they are? Really, how they use their free will. AKA the decisions that they make, especially the important ones.So I theorize that the Toa Empire Onua and the original Onua are entirely different people, kind of like identical twins. They look the same, sound the same, in some ways they think the same but they are different people and make significantly different choices under identical circumstances.WWhich presents and interesting picture; zillions of Onuas spanning the whole range of possible combinations of important decisions. A moral and mental spectrum of Onuas.Now this doesn't work for humans, because we are real people and are not mass produced to neatly fit every slot in a multi-dimensional spectrum, but it works pretty well for robots.Anyway, I hope that was clear. Stomp on, gaze in wonder at, or snort derisevely regarding my theory as you see fit. - 55555
