Awhile ago, I posted a headcanon on the usage of "Slizer" and "Throwbot" in-universe. Well, I'm back dissect BIONICLE's obscure forerunner once again. For the uninitiated:
The line had two different storylines. In Europe and Australia, the story was about a planet with seven continents and a "Slizer Dome" on the north pole. In this version, the different factions were all at war. In North America, the story was of seven different planets whose inhabitants met on the eighth, the Judge Dome, to settle disputes. Now, "settle disputes" is quite vague, but it implies something more civilized than all-out war. Both stories ended with a meteor striking the planet (or presumably the Judge Dome in the North American storyline) and causing mass destruction, leading to the poorly-defined 2000 storyline.
This next part is, admittedly, more headcanon from myself. It seems reasonable that the meteor strike happened at the end of the European storyline, and the meteor fragmented the planet into the many planets in the North American storyline. So, it's as follows:
1. Single planet with many sides fighting a war.
2. Cataclysm happens, resulting in multiple planets.
3. Former soldiers use a more tempered system of combat now.
Does anybody else see the ties to the story of the Core War and the Shattering? I believe Greg confirmed that, at the beginning, the only thing planned was the Great Beings building Mata Nui as a universe-housing robot, and the parts about the Glatorian and Bara Magna were added when it was decided to "refresh" the BIONICLE story. Think anyone working at LEGO took inspiration from BIONICLE's ill-fated predecessor?
