im just gonna jump in here and point out that while the GTVA colossus was able to focus, as AlphaOne states, 6 to 8 beam cannons on the Sathanas juggernaut, it just cant fire as quickly or sustain its fire as long. As a result the colossus would probably be able to get off hmmmm.. 2 shots from all their cannons while the shivans hit them 5 times everyshot? well in the end the colossus will be destroyed much more quickly.
Back on topic, i think the GTVA will construct a new version of the colossus, but only one. Since its gonna be pretty expensive to build
of them. construction will be much quicker because a lot of proven tech would be integrated into the new design, not to mention the GTVA would prolly have learnt a couple of things when constructing the first colossus. Added with possible new technology and weapons, i cant see why wont the GTVA build a new one. plus you have the added benefit of the new colossus being a massive deterrant to any sort of rebellion or revolt that might arise. heck it could also be the new symbol of unity for the GTVA
well yeah that what i think
